Production method for direct-seeding winter rape suitable for mechanized harvesting

Abstract

The invention relates to a production method for direct-seeding winter rape suitable for mechanized harvesting, and belongs to the technical field of mechanized planting of crops. The production method specifically comprises the steps: (1) selecting seeds; (2) performing mechanized sowing and fertilizing; (3) performing management in a rape growth period; and (4) spraying a ripening agent 2-3 daysbefore rape harvesting, and performing mechanized one-time harvesting, wherein, the specific pesticide fertilizer and growth regulator and the like employed in the method are all capable of greatly improving the yield of rape. Population density of rape planted by the direct-seeding winter rape production method is suitable, and the plant height, growth angle, pod bearing position and maturity are all basically uniform, so that the method is very suitable for mechanized harvesting. In addition, the production method is capable of greatly improving efficiency of mechanized harvesting of winterrape and reducing loss rate, and compared with a manual harvesting method, the method has the advantages that the harvesting time consuming is shorter, the ratio of output to input is higher, labor cost is more favorable to be reduced, and the economic benefit is better.

Description

technical field [0001] The invention belongs to the technical field of mechanized planting of crops, and relates to a production method of direct-seeded winter rapeseed, more specifically, the invention relates to a production method of direct-seeded winter rapeseed suitable for mechanized harvesting by using drug coupling to regulate the plant type of direct-seeded rapeseed . Background technique [0002] Rapeseed is the main source of edible vegetable oil in my country. Rapeseed oil accounts for more than 40% of my country's self-produced vegetable oil. my country's rapeseed production is divided into two major production areas: winter rapeseed and northern spring rapeseed. They are mainly concentrated in the provinces along the Yangtze River Basin. Among them, winter rapeseed is planted The area accounts for about 90% of the total area of ​​rape in the country. In recent years, the sown area and total output of winter rapeseed in my country have increased significantly, e...

[0003] For a long time, the rice-oil-rice planting method has been mainly adopted in the winter rapeseed planting areas in the coastal areas of Jiangsu. The last stubble is usually rice. The sowing and harvesting of rapeseed have seasonal conflicts with rice production. The traditional manual harvesting process is mainly to manually cut down Finally, put it in the field, and then manually thresh, transport, and dry it in the sun after 5 to 7 days. The rapeseed is cut down manually and placed in the field for a long time, which not only affects the pla
