High-yield culture method for planting cotton in high-risk cotton region

Abstract

The invention provides a high-yield culture method for planting cotton in a high-risk cotton region. The technology adopts double-wide-film mulching, the influence caused by low temperature, rain damage, wind damage and the like in spring on the seedling emerging is effectively resisted, and the seedling emerging is fast, regular and uniform; the multi-time intertillage and few-time chemical control technology in the seedling period is combined, the earth temperature is raised, the early emerging of strong seedlings is effectively promoted, and the seedling retaining rate and the strong seedling rate are improved; the water control is used as a main measure, the chemical control is used as an auxiliary measure, the water is saved, the pesticide is saved, and the premature senility is prevented; organic fertilizers (humic acid) and special fertilizers (special drip-irrigation fertilizers) are heavily applied, few chemical fertilizers are applied, the fertilizer effect is enhanced, and the soil and environment pollution is reduced; first watering is carried out later at proper time, the watering is stopped early, the water utilization rate is improved, and the early ripeness is promoted; top pruning is carried out early at proper time, the useless fruit branch number is reduced, the plant height is reduced, and the falling is prevented; maturity acceleration is carried out early at proper time, the harvesting can be carried out for many times in the early period, the loss rate is reduced by 5 to 10 percent, and the yield is improved.

Description

technical field [0001] The invention belongs to a crop cultivation technique, and relates to a high-yield cultivation method for planting cotton in a high-risk cotton area north of 46° north latitude. Background technique [0002] The range suitable for planting cotton in the world is about 18-46° north latitude and 76-124° east longitude, and the area suitable for planting cotton in my country is roughly within this range. According to different regions, my country's cotton-growing areas can be divided into four major cotton areas, among which the Xinjiang cotton area in the northwest inland cotton area is an important cotton-growing area, and it is also the cotton-growing area with the highest yield per unit area in the country and even in the world. According to the scope of cotton planting, the area (Xinjiang) suitable for cotton planting starts from the southern edge of Karamay in the south, Manas County in Xinjiang in the north, Hami City in Xinjiang in the east, and t...

Problems solved by technology

[0003] The purpose of the present invention is to break the history that high-yield cotton cannot be planted north of 46° north latitude in northern Xinjiang, and to solve the problem of frequent natural disasters in spring in some farms in this area, and the unstable temperature in summer and autumn leads to poor emergence, weak growth, late maturity, and low yield. A series of problems such as poor quality, aiming at the biological characteristics of extra-early-maturing cotton varieties and technologies such as disaster reduction and high-yield, propose a high-yield cultivation technology for planting extra-early-maturing upland cotton in high-latitude and high-risk cotton areas, reaching north of 46° north latitude in northern Xinjiang The purpose of planting high-yield, high-quality and high-efficiency cotton in high latitude areas
