Abstract

The invention relates to a cotton cultivation method. The method comprises the following steps: sowing of cotton seeds and laying of drip irrigation pipes: sowing three rows of cotton seeds under a mulching film, laying a drip irrigation pipe on each row; drip irrigation of seedling emergence period water; drip irrigation of bud period water, wherein the maximum water holding amount of the soil in the bud period is 70%-80%, the drip irrigation liquid of the bud period water is clear water or a water and fertilizer mixed solution; drip irrigation of flowering and boll-setting period water, wherein the maximum water holding amount of the soil in the flowering and boll-setting period is 80%-90%, and the drip irrigation liquid of the flowering and boll-setting period water is a water and fertilizer mixed solution; drip irrigation of boll opening period water, wherein the maximum water holding amount of the soil in the boll opening period is 60%-70%, and the drip irrigation liquid of the boll opening period water is clear water or a water and fertilizer mixed solution. The method also comprises the steps: flowering and boll-setting period chemical topping, flowering and boll-setting period cotton spindling controlling, and ripening and defoliating. Water and fertilizer are saved, water, fertilizer and sunlight can be fully utilized by the cotton, the mechanical production is achieved, manpower and material resources are saved, and finally the cotton yield is improved.

Description

technical field [0001] The invention relates to the technical field of cotton planting, in particular to a method for cultivating hybrid cotton using drip irrigation technology. Background technique [0002] Cotton production has an important position and role in my country's agricultural production. The superior natural endowment conditions make the national cotton layout concentrated in Xinjiang. Cotton production occupies a leading industrial position in Xinjiang's agricultural development. Cotton is still the most comprehensive advantage among the major crops in Xinjiang. agricultural products. Cotton drip irrigation technology is a new type of field crop irrigation technology developed on the basis of cotton film cultivation technology; due to its high efficiency and water saving characteristics, cotton drip irrigation technology has begun to be widely used in agricultural production in recent years. The effects of saving water, saving fertilizer and increasing producti...
