High-yield, high-efficiency and simple cultivation method for dryland wheat

Abstract

The invention discloses a high-yield, high-efficiency and simple cultivation method for dryland wheat. In order to meet the planting requirements of dryland wheat, in the process of planting dryland wheat, excellent wheat products with drought resistance and barren resistance are selected, a field cultivation and management system for storing water and preserving moisture is established, soil fertility is improved, reasonable fertilization, sowing with adequate moisture at an appropriate time, field management and corresponding prevention and control measures are adopted according to differentplant diseases and insect pests characteristics, so that the planting yield of dryland wheat can be effectively improved, the planting benefit can be improved, and the development of the wheat industry can be promoted; the early and deep fertilization of fertilizers is used to increase the root penetration before spring and winter, increase the root-shoot ratio, enable the root to fully absorb the water and nutrients in deep soil; and a reasonable group management strategy is adopted, and the grain number per spike and 1000-grain weight on the basis of large groups are synchronously increasedto increase the yield of dryland wheat, and thus not only the risk of rain topdressing at the later growth stage of wheat is reduced, but also cost and labor are saved, so that the method is efficient and simple.

Description

technical field [0001] The invention relates to the technical field of crop cultivation, in particular to a high-yield, high-efficiency, light and simple cultivation method for dryland wheat. Background technique [0002] Wheat is the main food crop in my country. Its growing season is the period of severe drought in northern my country. Wheat production has been low and unstable for a long time. This is due to the frequent threat of drought on the one hand, and the incomplete utilization of precipitation resources on the other hand. More important immediate reasons. Therefore, improving dryland wheat yield is of great significance for coping with drought and ensuring food production. [0003] The existing dryland wheat production technologies are mainly: [0004] 1. Cultivation: Dryland wheat mostly adopts deep plowing to store moisture, shallow plowing to preserve moisture, and rotates plowing every other year to increase the accumulation of precipitation in the plow laye...

Problems solved by technology

[0010] 1. Fertilizer needs to be applied in batches. Topdressing is limited by the rainfall after the wheat turns green. If there is no rainfall and no irrigation, it will cause the situation that the fertilizer cannot be applied, which will affect the growth and development of wheat in the later stage, and the phenomenon of defertilization will occur.

And topdressing fertilizer is labor-intensive and time-consuming
