Henan rapeseed green high-efficiency cultivation technology succeeded

"It turns out that my 800 mu of land is wheat, which is not only prone to waterlogging, but also because the maturity of wheat is late, affecting the cultivation of the next rice. After replanting rapeseed, it is not only simple to manage, it does not affect the rice. Planting, you can earn an extra 200 yuan per mu of land."

The author said that Ding Zhifa, the head of the planting of the Taiping Planting Cooperative in Gushi County, Henan Province, has planted all of his 800 acres of land into rapeseed, and the variety of rapeseed he planted comes from Zhang Shufen, a researcher in the rapeseed research laboratory of the Institute of Economic Crops, Henan Academy of Agricultural Sciences, has developed a new double-low rapeseed variety, Fengyou 10, Shuangyou 195 and Zashuang 7 and so on.

It is reported that these rapeseed varieties have the characteristics of low erucic acid and low glucosinolates. The oleic acid content is above 60%, close to 70% of olive oil, and the saturated fatty acid content is only about 4%, which is lower than olive oil. Civilian olive oil.

Gushi County is a comprehensive demonstration county of scientific and technological achievements of the “Modern Agricultural Science and Technology Demonstration Project” of Henan Academy of Agricultural Sciences. It is also a demonstration county of the national rapeseed modern industrial technology system and one of the main rapeseed producing areas in Henan Province.

On May 10th, the on-site observation meeting of “High-quality and high-yield rapeseed hybrids and high-yield simplified cultivation techniques demonstration” was held in Taiping Village, Guolutan Town, Gushi County. The delegates observed the local growth of rapeseed and the rapeseed of Zhang Shufen’s team. The variety is tested on site.

In order to achieve cost reduction and efficiency, according to the characteristics of high-quality hybrid rapeseed and its fertility characteristics and developmental rules, Zhang Shufen's team determined the efficient production technology of “five changes and five drops”. After adopting this technology, the sowing and harvesting of rapeseed were mechanized, and the control effect of aphids in seedling stage was close to 100%, and the control effect of aphids in flowering stage was still as high as 90%. According to the characteristics of inconsistent ripening of rape pods and easy breakage of pods, combined with the sowing time of local sorghum crops, combined harvesting is used when time is sufficient, and harvested by segmentation.

“In order to ensure the national food production area, ensure the safe supply of edible vegetable oil and vigorously tap the production potential of oil on limited land, and use mechanical sowing and harvest to reduce management costs when rural labor is increasingly scarce. The demonstration and promotion of hybrid rapeseed and high-efficiency production technology has played a typical role in driving," said Zou Qingpeng, deputy director of the Henan Academy of Agricultural Sciences.

It is understood that in addition to Gushi County, the rapeseed team of Henan Province and the high-efficiency production technology have adopted the same demonstration and promotion mode in other major rapeseed producing areas in Henan Province. According to the measurement results of the production team, the per mu yield of rapeseed in Gushi, Luoshan and Xinxian is about 300 kg, and the per capita yield of rice in Luoshan County is as high as 311 kg, creating a high-yield record of paddy field in the province. .
