Simplified and efficient cultivation method for ratooning rice interplanted oilseed rapes

Abstract

The invention belongs to the technical field of oilseed rape cultivation and discloses a simplified and efficient cultivation method for ratooning rice interplanted oilseed rapes. The simplified and efficient cultivation method comprises the steps: selecting an oilseed rape field; selecting oilseed rape and ratooning rice varieties; preventing and controlling weeds in the field by using a stem andleaf herbicide; sowing oilseed rapes, and interplanting ratooning rice; mechanically harvesting the ratooning rice; drying seeds before sowing; uniformly mixing the seeds with dry fine sand or fine soil, then, uniformly blending the mixture with a base fertilizer, and carrying out broadcast sowing; interplanting the oilseed rapes; uniformly spraying the herbicide once at the stage that the oilseed rapes have 3-5 leaves; and preventing and controlling pests at a seedling stage, and preventing and controlling sclerotinia sclerotiorum at a flowering stage. According to the simplified and efficient cultivation method, light, heat and water resources before the ratooning rice leaves from the field are sufficiently utilized to strive for early seedling and full seedling of oilseed rapes as wellas early and rapid growth, so that the simplified and efficient cultivation method lays the foundation for early maturation and high yield of winter oilseed rapes, promotes the industrial developmentof oilseed rapes in China and has positive significance in guaranteeing grain and oil safety, increasing agricultural production and increasing income. Compared with a production status of oilseed rapes in Jiangxi, the method disclosed by the invention is capable of increasing the production by 10% or above, reducing the cost by 20% or above and increasing the efficiency by 20% or above.

Description

technical field [0001] The invention belongs to the technical field of rapeseed cultivation, and in particular relates to a light, simple and high-efficiency cultivation method for inter-sowing rapeseed with ratooning rice. Background technique [0002] Rapeseed is one of the main oil crops in my country. Oil crops are an important source of vegetable oil and protein in people's daily life, and are also important industrial raw materials, occupying an important position in agriculture and national economic development. China is a big oil producer and the largest consumer: in recent years, the domestic oil supply has been in short supply for a long time, and the self-sufficiency rate has continued to be less than 60%, and the proportion of imported oil in domestic consumption has continued to rise; at the same time, with the development of society and economy , my country's animal husbandry and aquaculture are in the process of rapid development, and there has been a serious ...

AI Technical Summary

Problems solved by technology

[0003] To sum up, the problems existing in the prior art are: since the harvest of ratooning rice is generally in late October, and the suitable sowing date of direct seeding rape is generally before mid-October, the sowing date of rapeseed after ratooning rice is harvested is late, which limits the direct seeding. Rapeseed Yield
