When we pick up a bowl of white rice, the first thing that comes to mind is Yuan Longping, the father of hybrid rice.As we all know, he miraculously let grain harvest and increase production, the knowledge of serving the country as a concrete heart of grain, for China and the world’s food security made important contributions, for this was awarded the “Medal of the Republic”.At 13:07 on May 22, 2021, Yuan Longping died in Changsha, Hunan province, just like a rice plant falling into the soil.”Yuan Longping likes to see rice in thousands of heavy waves, and he is the most romantic yuan Longping.” All his life, he rooted himself in rice fields and cultivated the fields by himself, realizing the simple wish of the people for thousands of years and lifting hundreds of millions of people out of hunger.A grain of rice incense, a burst of rice waves, a mu wo field, his departure, let the people shed tears, into a “Yuan Grandpa, all the way good!”However, many people may not know that he also has an indissoluble relationship with the development of rice in Nanling County.He visited Nanling twice and planted a deep rice friendship here.On September 23, 2009, Yuan Longping instructed the production of super hybrid rice in Nanling.The Propaganda Department of Nanling County Party Committee offered wuhu as one of the “four big rice markets” in China as early as the Ming Dynasty. Nanling County, as the main rice-growing area of Wuhu, has the reputation of “Rice market of Wuhu and Granary of Nanling”.Since the 1990s, Nanling County began to study the stable and high yield of rice.”We all believe that if we have food in our hands, we will not panic.”Cheng Taiping, director of Wuhu Xinghuo Agricultural Practical Technology Research Institute, said, “The rice bowl firmly in our hands, stable yield is the basis, high yield is the key, we should strengthen the protection and utilization of germplasm resources and breeding and promotion of excellent varieties, while carrying out key agricultural core technologies.”With the joint efforts of Cheng Taiping and other experts, Nanling County has made a “glorious turn” in its rice planting mode. The five technologies of direct seeding rice, allelic rice, extra early maturing rice, low early maturing regrowth rice and Chinese milk veg rice have been tested and promoted, which have created a number of national no.1 and are known as the “five golden flowers” of rice planting.Direct seeding rice: Planting rice no longer stoop to transplanting rice seedlings, directly sowing rice seeds what is direct seeding rice?”Different from traditional transplanting rice, direct-seeding rice does not need to go through the process of seedling raising and transplanting, which saves labor costs to some extent.”Cheng Taiping dispelling doubts, rice seeds soaked for 36 hours, after bud, can be sown into the field, greatly improved efficiency.As early as 1992, Cheng Taiping has been working on rice direct seeding technology for 30 years.It is because of the advantages of simplicity, cost saving and efficiency, the majority of farmers have been recognized.Nanling is the birthplace of direct seeding rice technology, which is used in 70 percent of anhui’s rice cultivation.”Seventy percent of the planting area is directly related to food security, rather than the traditional model of rice cultivation and transplanting in the past. It is equivalent to 70 percent of every bowl of rice we eat comes from rice direct seeding technology.”Cheng Taiping image metaphor.Aerial seeding of rice by drone.The key technology of direct seeding rice lies in changing the traditional rice planting mode and cultivating rice varieties suitable for direct seeding cultivation. Compared with transplanting rice, direct seeding rice varieties have the characteristics of lodging resistance, stable yield and high yield.In the 1990s, the direct rice production technology was only applied to single-cropping rice. Although the direct rice production area was more and more extensive, it still could not be applied to direct rice production of double-cropping rice.Cheng Taiping breaks new ground, seek breakthrough from breed.In 2005, “Wandao 143” passed the variety examination of Anhui Province, which directly turned double season direct-seeding rice breeding from ideal into reality. It is also the first direct-seeding rice variety examination in China.Allelopathic rice: Allelopathic rice can suppress weeds without the use of herbicides. The English name for allelopathic rice is “Allelopathy”.In agriculture, the term has long been used to describe the biochemical interactions between plants that inhibit the growth of neighboring plants, extending to rice cultivation and the relationship between rice and weeds.”Currently, herbicide control in rice fields is mainly dependent on chemical herbicides.Without manual weeding or herbicide application, rice cannot compete with weeds.”Cheng Taiping frankly.After repeated plant trials, Cheng found that breeding “green rice”, which inhibits weed production, was an important way to reduce the use of chemical herbicides, supported by cultivation and management measures.So how can we find a rice variety with the ability to suppress grass?Wild rice is the best proof!Under the long-term pressure of natural selection, wild rice has accumulated many good character-determining genes, which also provides opportunities for new gene mining and planting innovation. Its existence belongs to natural growth, so wild rice is also called grass-suppressing rice.In Cheng Taiping’s view, rice individuals who survive in the harsh weed environment should be screened naturally, and unstable populations formed by breeding techniques such as sexual hybridization of the rice should be formed, and then new rice varieties should be selected by using the weed environment co-coercion, and then targeted rice growth allocation should be carried out to establish a set of grass-suppressing rice pattern.This approach has proved successful.Allelopathic rice variety 6173 and Allelopathic rice variety 2205 were successively developed by Wuhu Xinghuo Institute of Agricultural Practical Technology, which had strong inhibition effect on symbiotic weeds. Allelopathic rice variety 6173 had great influence in academic circles, and provided germplasm resources for allelopathic rice production and application.Based on the research of direct rice production technology, “Huagan 2205” and “Nanling Zao 2” have been successfully cultivated in Nanling. Their contribution lies in that they are extra-early maturing early-rice varieties.”It only takes 94 days from sowing to ripening, compared with more than 105 days for ordinary early rice. Although it is only more than 10 days earlier, it is far beyond our understanding of extra early rice.”Cheng Taiping said.In his view, the emergence of extra early-maturing varieties has solved the problem of rice being able to be harvested before the plum rains hit, allowing early rice to “avoid disasters” and return to the barn.Cheng Taiping does rice hybrid in the field.Nanling county party committee publicity Department for the figure for double cropping rice planting, before and after the start of autumn points in the morning and evening, farming time varies.It is precisely the extra early ripening early rice that is more than 10 days earlier, so that the traditional double cropping rice production has a fundamental change, the past so-called “double rush”, harvest early rice, planting late rice, is no longer the traditional rush to harvest and plant.The implication is that the emergence of precocious varieties solved the problem of farming.After the first crop is harvested, there is enough time to plant the second crop, so that the annual double cropping rice yield is stable and increased.The Jianghuai River Basin is prone to large-scale flooding during the plum season. As water recedes late in many farmland, rice cannot be planted, and the extra early-maturing rice delays the safe sowing date of existing relief rice varieties by more than 10 days, ensuring that more affected farmland can produce grain.New rice on the market in advance, for the people, can taste fresh taste new earlier, eat safe and healthy rice;For farmers, the rising price of rice will increase their income from farming.In Cheng Taiping’s view, the promotion and planting of extra-early maturing varieties has provided a new idea for the adjustment of agricultural industrial structure and promoted the integrated development of agricultural industry and industrial technology.At present, there is a shortage of labor force in rural areas. However, there has always been an imbalance of labor force in rice production, resulting in the contradiction between the shortage of labor resources and idle.Based on this consideration, regrowing rice is one of the ways to solve the imbalance of employment.What is regenerative rice?As the name implies, it is the first harvest of rice, the use of rice piles to re-sprout, grow ears, mature and harvest another season.Heading performance of nanling soft treasure regeneration season.Nanling county Party Committee propaganda Department for traditional recycled rice, there is a saying in the folk: the regeneration of that crop, some of the harvest, lost.In Cheng Taiping’s view, if you can’t solve the problem of the yield of the regenerative season, the significance of the existence of the regenerative rice will be lost.”Because the harvester will crush the rice crop, which can reduce production or even fail to harvest, it shows that traditional rice is not suitable for mechanized operations.”Cheng Taiping led a team to study low-maturing regenerated rice.”If agricultural machinery cannot be solved at present, we should start with agronomy.Low and early maturing regenerated rice will not be crushed by machinery, but can also ensure the safety and stable yield of regenerated crops.””At the end of the day, the pattern of growing regenerative rice is all about ensuring a consistent yield for the second crop.”Cheng Taiping revealed that low early maturing regenerative rice through continuous years of research, the current seed is going through the approval process, once passed, will provide a new way for food security production, rice production and labor balance.To his delight, a farmer in Fanchang District of Wuhu city has used direct seeding technology to plant 100 mu of low-maturing regenerative rice varieties in 2021. The first crop harvested more than 1,000 jin, and the second crop yielded more than 700 jin.”This is the final yield harvested under more extensive management, if refined management, an increase of 200 jin is not a problem.”Cheng Taiping calculated an account, once the production, this is the so-called tons of grain.When it comes to nanling’s rice cultivation, we have to mention its unique Chinese milk veg rice.As a grain production county, but also the provincial Chinese milk veg seed regional fine seed breeding base, Nanling has been planting Chinese milk veg tradition.At present, the county has a planting area of nearly 200,000 mu, and has grown nine new varieties of Chinese milk veg, producing 3.2 million kilograms of Chinese milk veg seeds, accounting for a quarter of the national total output.The so-called Chinese milk vetch rice, that is, Chinese milk vetch is used as green fertilizer to grow rice.Sheets of milk vetch.Established in 1989, Wuhu Qingyijiang seed industry is the country’s first green fertility and reproduction integration of seed enterprises, specializing in Chinese milk cloud seeds and rice seeds research and development and production.At present, ziyunying Yi Jiang seed developed and produced by the company has achieved full coverage of southern rice areas, which has not only won the title of national crop excellent varieties and Anhui famous brand products, but also won the Chinese well-known trademark.Wang Genhuo, chairman of Qingyijiang seed industry in Wuhu, introduced that Chinese milk veg yijiang seed can not only improve the soil, protect the ecology, but also beautify the environment, and is the largest Chinese milk veg variety to be promoted in the country at present.Seed is the chip of agriculture, farmland is the lifeblood of agriculture.Wang Genhuo, who has been engaged in the research and development of Chinese milk vetch seeds for many years, knows that Chinese milk vetch, as a green fertilizer, is equivalent to fallow land. Planting Chinese milk vetch is the best way to combine planting and cultivating land.In recent years, the cultivated land in rice-growing areas has been affected by chemical fertilizers to varying degrees, and the demand for Chinese astragalus is getting higher and higher. The qingyijiang seed industry in Wuhu has been breeding plants with high yield, many seeds and long flowering period. In Wang Genhuo’s view, Chinese astragalus can be eaten, enjoyed and harvested honey, and also returned to the field as green fertilizer.”To cultivate the head of nanling rice varieties, good varieties with good green fertilizer, and create a good brand, finally achieve the goal of negative growth of chemical fertilizer, this is the significance.”Wang Genhuo said.Spring breeze and rain, and quickly usher in the rice sowing season, as a “granary” Nanling, the reason why can in rice cultivation, innovation results, and the local county party committee county government has always attached great importance to inseparable.To carry food security responsibility, the south, has issued a “NaLing rice industry development plan notice and on the packages to protect harvest bureau of agricultural and food setting up contact service notice, clear will be 90% of the rice subsidies, adjusted for early rice, YiJiDao and double late actual acreage of subsidies.At the same time, integration project funds continue to support the development of rice industry.A porridge a meal, when the hard-won.Nanling county officials said in an interview with “Chat current situation”, “in order to achieve the simultaneous improvement of varieties, quality and brand of Nanling rice, enhance the market competitiveness of Nanling rice, to ensure that The Chinese bowl containing Chinese grain, Chinese grain with Chinese seeds.”Source: Chat about the current situation author: Wang Ruihua
