" to improve the yield of recycled rice per mu, China has an important food security production and strategic development significance. This is not by the abuse of pesticides and fertilizers, but the need for multi-disciplinary, multi-ecological areas to work together, around the cultivation of rice advantages of industrial areas, the creation of high-yield cultivation technology model. Xie Hua'an, a plant genetic breeder,
, and a researcher
Fujian Province Agricultural Research Institute, said in Fuzhou on the 29th.
29, the third Southeast Science and Technology Forum of Fujian Province, focusing on the theme of "Agricultural Green Development and Rural Industrial Revitalization", was held in Fuzhou. Xie Hua'an delivered a keynote report entitled "Science, Technology, Innovation and Food Security".
Xie Hua'an recalled that in the 1980s, China's first generation of hybrid rice rice plague resistance was weak, so that farmers in many areas of the grain no harvest. In order to solve the problem of "chip of grain", it is envisaged that simply relying on the introduction of good varieties from abroad, Chinese scientists have worked hard for decades to cultivate a strong recovery system with independent intellectual property rights, especially the creation of China's first "Ming-Hui 63", which achieved outstanding results.
1990 to 2010, China created the second generation of hybrid rice excellent quality. Among them, hybrid rice seed "Yuyou 63" became the first national high-quality hybrid rice varieties, from 1986 to 2001 for 16 consecutive years, has been The largest area of rice cultivation in China. "Yu you 63" also spread to Southeast Asian countries and large-scale cultivation, by local farmers as "Oriental God Rice."
Xie Hua'an said that in that year, the progress of the breeding industry depended on technological line innovation, and now, based on traditional breeding methods, combined with genetic engineering, cell engineering and chromosomal engineering technology, plant mutation technology, molecular breeding and genome editing technology, in-depth research on basic theories such as anti-reverse genetic breeding and optimization of breeding procedures, the creation of excellent characteristics of the breeding material or new varieties.
aimed at "recycled rice", Xie Hua'an continued to work in Sanming, a mountainous area of Fujian Province, for another 20 years.
rice is the use of rice piles after harvest survival sleep buds, germination into regenerative rice, and then spike mature rice. In Xie Hua'an's view, renewable rice has the advantages of low production cost and high economic benefits.
He believes that, as a resource-saving and efficient rice production system, recycled rice can effectively avoid the dangers of diseases such as rice mosquitoes, is conducive to improving the comprehensive production capacity of rice paddies, suitable for planting a single-season rice area in southern China with more than one season of light temperature resources and two-season light temperature resources are insufficient ecological areas.
Xie Hua'an with a set of data to show that in Fujian's breeding area, Fujian Sanming Yuxi, 100 acres of demonstration park has been 21 consecutive years to achieve high yield of recycled rice, the highest yield of 928.3 kg per mu, very impressive. And in another full mechanization of Fujian Pucheng 100 acres of recycled rice demonstration area, but also achieved a good yield.
Xie Hua'an admitted that there are 160 million mu of single-season rice fields in southern China, it is estimated that 50 million mu of suitable renewable rice, if the yield can be gradually raised to the level of production in Yuxi, Fujian Province, can add 20 billion kilograms of rice per year, "which is only 7% of the world's arable land, accounting for 22% of the world's population of China is of great significance." Xie
believes that this goal must not be at the expense of ecology, "to keep clean soil, leaving for future generations to cultivate, has always been the ideal and pursuit of my generation."
