Method for planting rape in dry land for field management by adopting small machine

Abstract

The invention discloses a method for planting rape in dry land for field management by adopting a small machine. The method comprises the following steps of: after harvesting previous rape in the dry land, carrying out dibble seeding on the rape according to a method of sowing 5-8 grains of seedlings in each row at the row pitch of 50-60cm and the plant space of 15-20cm; finishing final singling in one step when the rape is grown to form 3-5 true leaves; leaving 2-3 seedlings in each row and controlling the density to be 13,000-18,000 plants / mu; when the rape grows to form 6-8 true leaves, scattering 10-15kg of urea as fertilizer for seed bed along a rape row line by one person in front of a walking tractor; and carrying out field management by adopting a method of turning plow, earthing up and covering the fertilizer by using the walking tractor with a plowshare through one person at the back of the walking tractor. According to the method disclosed by the invention, the wide-row and density-planted sowing is carried out to ensure the small agricultural machine can enter the field and participate in management during seedling stage of the rape, the fertilizer for seed bed application, weeding, cultivation and earthing up and ditching one-time operation of the rape in dry land can be realized, the labor input for the field management is reduced, the work efficiency is improved and the timely and effective development of the field management during the seedling stage of the rape is ensured.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and in particular relates to a method for planting rapeseed in dry land suitable for field management by small-scale agricultural machinery. Background technique [0002] rape( Brassica napus ), belonging to Brassicaceae, Brassica, is the main source of vegetable oil for human consumption and one of the main economic source crops for farmers. Rapeseed planting mainly includes paddy field rapeseed with rice as the fore-crop and upland rapeseed with corn and flue-cured tobacco as the fore-crop. Among them, the sown area of ​​dryland rapeseed in Yunnan has reached more than 2 million mu, accounting for more than 50% of the province's rapeseed area, and the per capita arable land in dryland rapeseed production areas is more, and the average dryland rapeseed area per household is more than 5 mu. [0003] Rapeseed is "three-point planting and seven-point management". Timely and effective fie...

AI Technical Summary

Problems solved by technology

Due to the lack of labor force, the management of seedlings is often not managed in time or even extensively, which leads to weak growth of rapeseed seedlings, weak ability to resist natural disasters such as drought and freezing damage in the later period, and aggravates the damage of weeds, clubroot, aphids and other diseases, insect pests and weeds. Occurrence and degree of harm, resulting in low and unstable yields
