Problems solved by technology

[0003] In the cotton planting in the south (middle and lower reaches of the Yangtze River and the Yellow River Basin), the planting density is about 2000 plants / mu, because the south is rainy and the plants are tall, which makes it difficult to mechanize the cotton harvest in the south, which greatly increases the production cost of cotton in the south
[0004] Although the area of ​​cotton in the south has dropped significantly in recent years, the planting area of ​​some old cotton areas still exists to a certain extent

Abstract

The invention relates to a cotton planting method. The cotton planting method comprises the following steps that S1, a base fertilizer is applied, and cotton seeds are sowed; S2, mepiquat chloride is used for treatment 15-18 days after seedling emergence, then cotton seedlings are treated once every 15-18 days through mepiquat chloride, and the planting density in the seedling stage is 10000-12000 plants per mu; in the seedling stage and the bud stage, mepiquat chloride is sprayed according to 1.6-2 g / mu; and 4-6g of mepiquat chloride is sprayed per mu in the flowering and boll-setting period. According to the cotton planting method, the yield of ginned cotton is ensured; and meanwhile, the cotton planting period is shortened, the fertilizing amount is reduced, and mechanical harvesting is achieved.

Description

technical field [0001] The invention relates to the technical field of planting, in particular to a cotton planting method. Background technique [0002] In traditional cotton planting, the planting density in Xinjiang can reach 12,000 plants / mu, laying the foundation for the mechanized harvesting of cotton in Xinjiang; [0003] In the south (the middle and lower reaches of the Yangtze River and the Yellow River Basin), the planting density is about 2,000 plants / mu. This is because the south is rainy and the plants are tall, which makes it difficult to mechanize cotton harvesting in the south, which greatly increases the cost of cotton production in the south. [0004] Although the area of ​​cotton in the south has dropped significantly in recent years, the planting area of ​​some old cotton areas still exists to a certain extent. [0005] Because the original southern cotton region can undertake a part of the cotton production task, how to realize mechanized harvesting bec...
