High-yield cultivation method for winter wheat spring planting

Abstract

The invention belongs to the technical field of wheat cultivation, and discloses a high-yield cultivation method for winter wheat spring planting. The method comprises the steps of screening, soil preparation, winter irrigation in November, seed dressing, timely sowing in early and middle ten days of March, irrigation after topdressing of seedling fertilizers at the tillering stage, prevention and control of plant diseases, insect pests and weeds at the middle and later growth stages, and timely harvesting. According to the method, the winter wheat is sown in a spring planting mode, the problem that the winter wheat cannot be sown since the winter wheat cannot become ripe through normal vernalization and heading in the spring wheat area of Qinghai is solved, so that the wheat can be normally produced without vernalization, and finally the high-quality cultivation method achieving high yield and low insect damage is obtained.

Description

technical field [0001] The invention belongs to the technical field of wheat cultivation, and in particular relates to a high-yield cultivation method for spring sowing of winter wheat. Background technique [0002] Wheat is the main food crop in my country. Wheat production is related to national food security issues. Strengthening wheat production, increasing wheat yield per unit area, and improving wheat quality are important ways to develop efficient agriculture. For a long time, spring wheat has been mainly cultivated in spring wheat areas in my country. Because winter wheat cannot undergo normal vernalization and heading maturity, winter wheat has not been planted in spring wheat areas. [0003] Now spring wheat has low population density, few ears per mu, low yield, poor lodging resistance, high yield but not high quality, high quality but not high yield, late maturity, more rain in autumn, lodging, ear germination, disease and insect pests and other reasons. [0004...

AI Technical Summary

Problems solved by technology

For a long time, spring wheat has been mainly cultivated in spring wheat areas in my country. Since winter wheat cannot undergo normal vernalization and heading maturity, winter wheat has not been planted in spring wheat areas.

[0003] Now spring wheat has low population density, few ears per mu, low yield, poor lodging resistance, high yield but not high quality, high quality but not high yield, late maturity, more rain in autumn, lodging, panicle germination, disease and insect pests and other reasons.

[0004] In the Qinghai plateau area, the altitude is as high as 2200-2600 meters. Winter wheat cannot be planted in the Qinghai spring wheat area. The long-term sowing mode is winter wheat autumn sowing and spring wheat spring planting. The advantages of winter wheat varieties cannot be fully utilized, and they are susceptible to disasters such as diseases, insect pests and hailstorms. , prone to a large number of dead seedlings
