Anti-low temperature preparation composition for cotton production, preparation method and application method thereof

Abstract

The invention discloses a low-temperature-resistant preparation composition for production of cotton, a preparation method and a using method of the low-temperature-resistant preparation composition. The low-temperature-resistant preparation composition for production of the cotton comprises a preparation I and a preparation II; the preparation I comprises a low-temperature-resistant nutrient substance, a plant nutrition promoter, an antifreezing agent, a surfactant and water; and the preparation II comprises a low-temperature-resistant nutrient substance, a plant nutrition promoter, a plant growth regulator, a surfactant and water. The preparation I is mainly used at a seedling stage, and the preparation II is mainly used at blossoming and boll-forming stages. The preparations can well prevent and retard influence and harm of low temperature to production of the cotton, solve the problem of cotton plant growth retarding, cut production and the like caused by low temperature damage in a main cotton production region, guarantee production effectiveness and stable income of cotton planters, are simple in preparation process, easy and convenient to use, environment-friendly and obvious in effect, and can be widely popularized and used in cotton regions.

Description

technical field [0001] The invention belongs to the technical field of agricultural production, and relates to a low temperature resistance preparation composition for cotton production, a preparation method and a use method thereof. Background technique [0002] Chilling damage is the damage to crops caused by low temperatures above 0°C during the crop growing season. Sometimes it even occurs at a temperature close to 20°C. After the crop is damaged, there is no obvious change in appearance, but it has a great impact on the formation of crop yield and quality. In the cotton-growing areas of northern my country, due to unstable temperature changes in spring, especially when encountering "late spring cold", the surface temperature is far lower than the minimum growth temperature of cotton seedlings, which seriously affects plant growth and yield formation. In the middle and late stages of cotton growth (July and August), strong cold and humid air flows in, and the continuous...
