Plantation technique for cotton protected areas with low-latitude plateau climate

Abstract

The invention provides a plantation technique for cotton protected areas with low-latitude plateau climate, and relates to plantation technique for cotton seedling growing, transplanting and field management under low-latitude plateau climate. During a seedling growing phase, means of cooling, moisture retention, shortening film-covering time and prolonging sunshade time are employed to prevent burning of seedlings during the very phase. Special seedbed fertilizer is used to facilitate growth of seedlings. The phase of transplanting to a field mainly involves cultivation in protected area of the field, one-time applying special cotton fertilizer and chemical regulation of whole processes and other comprehensive plantation technology, and the problems of too much rain during the field cultivation phase and drought in later phase can be solved. Weeds are effectively controlled, manual weeding and use of herbicides are reduced, and the cost is lowered.

Description

technical field [0001] The invention relates to a cotton planting technique, in particular to a planting technique of cotton seedling raising, transplanting and field management in a low-latitude plateau climate. Background technique [0002] Cotton is an important economic crop in China, mainly distributed in the Yangtze River Basin, the Yellow River Basin and Northwest China. In these planting areas, cotton planting and cultivation techniques are relatively mature, and most of them adopt seedling transplanting and field direct seeding. The Yangtze River Basin mainly adopts seedling cultivation and transplanting, with plastic film mulching, heat preservation, humidity reduction and disease prevention as the main technology. [0003] However, under the climate conditions of plateau and mountainous areas such as Yunnan, due to different geographical environments, such as strong light, strong ultraviolet rays, rapid temperature rise in sunny days, and strong dry and hot mount...

AI Technical Summary

Problems solved by technology

The implementation of the current conventional cotton planting technology may result in reduced production, poor quality, and low economic benefits.

Therefore, in Yunnan and other low-latitude plateau areas, there has been no successful example of cotton planting technology
