Method for mechanically harvesting winter rape efficiently with low power consumption

Abstract

The invention discloses a method for mechanically harvesting winter rape efficiently with low power consumption. The method comprises the following steps of: A, constructing a rape group suitable for mechanical harvest: selecting the variety suitable for mechanical production, performing mechanical precise-quantity direct seeding when the soil water content is 30 to 40 percent, and constructing an ideal group and a plant type by fertilizer and water application and disease inset pest and weed control; B, adjusting a mature period: spraying a ripener two to three days before the harvest of rape seed ripening stage in the regions of contradictory seasons; C, harvesting at right time: observing and measuring the morphological physiological index of the plant before the harvest of the rape, wherein more than 95 percent of siliques, namely yellow loquat fruits in the cropland are suitable for mechanical harvest; D, mechanically harvesting and measuring loss rate: harvesting by a special rape harvesting mechanism in a combining way in the period suitable for harvest; E, smashing and returning rape straw to the cropland: flooding the straw in water immediately after the harvest of rape, decaying and returning to the cropland. The method is easy and convenient to operate, improves a one-time efficient branch height, reduces the branch number, reduces the thickness of the pod layer, solves the problems of high harvest loss rate, and improves the yield.

Description

technical field [0001] The invention belongs to the technical field of crop mechanized planting, and specifically relates to a method for mechanized harvesting of winter rapeseed, which is suitable for mechanized harvesting of winter rapeseed in the Yangtze River Basin, can reduce the loss rate of mechanical harvesting, improve harvesting yield and production efficiency, and is ecologically friendly and beneficial to agricultural production sustainable development. Background technique [0002] Rapeseed is the main source of edible vegetable oil in my country, and rapeseed oil accounts for more than 40% of my country's self-produced vegetable oil. The Yangtze River Basin is the main planting area of ​​winter rapeseed. For a long time, winter rapeseed has been planted by transplanting seedlings and harvested manually at the mature stage. The harvesting process is: first, it is manually cut down and placed in the field, and then manually threshed, transported, and dried after ...
