Simplified high-yield cultivation method of summer sowing short-season cotton

Abstract

The invention discloses a simplified high-yield cultivation method of summer sowing short-season cotton. The simplified high-yield cultivation method comprises the steps of seed selection, agricultural implements preparation, fertilizer application, sowing, final singling in good time, disease pest and weed control, chemical regulation and tip pruning, and ripening and harvesting, the agricultural implements are maintained before sowing, plate stubble direct seeding is carried out after harvesting wheat, base fertilizer is applied along with sowing when mechanical sowing is carried out, early sowing, full stand and strong seedlings are achieved, and final singling is carried out in good time. According to the simplified high-yield cultivation method of summer sowing short-season cotton, compared with a conventional spring cotton plantation technology, planting density of the summer sowing short-season cotton is three times of that of conventional spring sowing cotton, the summer sowing short-season cotton is planted in a manner of yielding two crops a year, full mechanical operation can be achieved, labor, time and pesticides are saved, growth time is saved by one third, cost is saved by 1000-2000 yuan, willingness of farmers to plant the summer sowing short-season cotton is largely motivated, the problem of conflict between grain and cotton is also solved, planting benefits are largely increased, the national grain safety production strategy is not influenced, and production, consumption and reserve of the cotton are also ensured.

Description

technical field [0001] The invention relates to a simplified high-yield planting management technology for summer-sowing short-season cotton, which saves time and labor, and increases yield and efficiency. [0002] technical background [0003] Cotton belongs to angiosperms in plant taxonomy, Malvaceae, Gossypium, and is one of the important economic crops in my country. Cotton (fiber) is a necessity for people's life, and it is also an important industrial raw material and military material , plays an important role in the development of the national economy. China is the largest cotton producer and consumer in the world. The current annual demand is about 9-10 million tons, the domestic output is about 6 million tons, and the import ratio accounts for more than 50%. The situation of cotton safety production has undergone profound changes, and the degree of dependence on foreign countries tend to increase. [0004] At this stage, my country's agricultural planting structure...
