Fujian Ratooning Rice Achieves the Goal of "Ton Grain Fields" for 5 consecutive years

To achieve the goal of "tons of grain field" for full mechanized production of ratooning rice for 5 consecutive years! Located in the ratooning rice demonstration field in Heping Village, Shuiji Town, Jianyang District, Nanping City, Fujian Province, Professor Li Chunxi, the leader of the production measurement expert group and Professor Li Chunxi of Henan Normal University, announced that the average yield of the demonstration film during the regeneration season is 435.

The reporter learned on December 9 that the project is a national key research and development program "Selection of high-quality and high-efficiency rice varieties and its supporting cultivation techniques" undertaken by Professor Lin Wenxiong of Fujian Agriculture and Forestry University.

Aiming at the "low-yield" problem, build a machine-harvested ratooning rice technology

As a rice cultivation method with one sowing and two-season harvesting, ratooning rice not only has the characteristics of "two harvests, three without four, saving and five improvements", but also has significant ecological benefits.

Although the mechanized production of ratooning rice has obvious advantages in saving costs and increasing efficiency, the output has been difficult to break through

Lin Wenxiong told reporters that the regrowth characteristics of the variety, the vigor of the root system in the late stage of the first season rice, the low and unstable germination rate of the low buds in the regenerative season, and the mechanical harvesting and rolling are the main factors that limit the yield of the regenerative rice

In recent years, Professor Lin Wenxiong’s team has continued to carry out research on key technologies for mechanically harvested ratooning rice, and created the "full-process mechanized ratooning rice high-yield and high-efficiency variety selection and its three-guarantee, two-promotion and one-attack high-yield and high-efficiency cultivation technology system", which has been selected as "Yongyou 1540" "Taifengyou 3301" and many other rice varieties with strong ratooning power suitable for mechanical harvesting, through the study of the characteristics of the varieties, constructing a screening index system for mechanically harvested ratooning rice varieties; innovation and integration of ratooning rice high-yield, stable-yield and high-efficiency water and fertilizer management technology; preliminary Developed a small reclaiming rice harvester suitable for hilly and mountainous areas that can reduce mechanical harvesting and rolling and prevent tangling

Each mu can increase income by 500 yuan, and accumulatively promote 6 million mu

"High-yield machine-harvested ratooning rice can effectively change the status quo that rice is not profitable or even loses money

"For many years, with the support of Professor Lin's team, our cooperative has developed mechanized planting of low-stay ratooning rice throughout the whole process.

"This year, through the'cooperative + poor households' model, we signed trusteeship agreements with more than 10 poor households, trusting 216 acres of land, and planting mechanized regenerated rice throughout the process, effectively increasing the income of poor households from growing grain

It is reported that in recent years, Professor Lin Wenxiong’s team has compiled and distributed the "Regeneration Rice Model Map with a Per Mu Yield Ton Grain Field", "Regeneration Rice High-yield Cultivation Integrated Technical Manual", and held training courses, on-site observation meetings and other forms of exchange and training.
