A kind of convex-concave planting method of winter wheat

Abstract

The present invention relates to the technical field of crop planting, in particular to a convex-convex planting method for winter wheat. Within one week after the previous crop of wheat is harvested, the soil is subsoiled at intervals, ridges are formed in the non-subsoiled area, ditches are opened in the subsoiled area, and crop straw is covered. Form a convex-concave surface and soil-air barrier interface to promote the accumulation of rainwater into the soil; use herbicides to control weeds in the summer slack season; use fungicides or / and insecticides to dress seeds before planting wheat, adopt equal row spacing and equal sowing width, and fertilize The integrated operation of rotary tillage, seeding, and suppression realizes convex and concave planting of wheat; chemical weeding is carried out in the early winter; plant growth regulators and topdressing are sprayed in the turning green and jointing stages; Apply foliar fertilizer. The method reduces the negative impact of water and fertilizer stress on the growth and development of dryland wheat, improves material production capacity and water and fertilizer use efficiency, and stably increases wheat yield by transforming soil, straw mulching to collect rain and moisture, convex and concave planting, and root zone positioning fertilization.

Description

Technical field[0001]The present invention relates to the field of crop planting, and more particularly to a method of convex and concave planting in winter wheat.Background technique[0002]Winter wheat is the main food crops in the drought zone in my country. Due to less drought, there is a lack of suppression and soil barren, difficulty in topdipage, causing dry wheat yield and unstable, water and fertilizer utilization efficiency is low. Therefore, it is important to explore water-saving cultivation and nutrient management measures that can collaborate in increasing production and water fertilizer utilization efficiency, which is critical to the sustainable development of wheat industries and the national food security.Inventive content[0003]It is an object of the present invention to provide a winter wheat convex and concave planting method to improve the water and fertilizer utilization rate of dry land and increase wheat production.[0004]In order to solve the above technical pr...

Problems solved by technology

[0002] Winter wheat is the main food crop in dryland areas in my country. Due to the lack of precipitation, lack of supplementary irrigation, poor soil and difficulty in topdressing in drylands, the yield of dryland wheat is low and unstable, and the efficiency of water and fertilizer use is low.
