AI Technical Summary

Technical Problem

In the production of saline-alkali land cotton in Xinjiang, the traditional method of light salt reduction requires a large amount of water sources and a good drainage system. However, the shortage of water resources in Xinjiang is unable to support a large amount of light salt reduction work, resulting in the lack of obvious improvement of the yield and quality of saline-alkali land cotton in the production and quality of saline-alkali land cotton.

Method used

A cultivation method for reducing alkali in saline-alkali cotton is proposed, including deep cultivation of base fertilizer, irrigation and entropy, live streaming of plastic film covering and machine-picked cotton planting mode, staged fertilization and pest control, to improve cotton yield and water utilization efficiency.

Benefits of technology

By improving soil structure and water-salt movement, reducing soil salinity content and improving cotton yield and quality, it is suitable for Xinjiang saline-alkali cotton fields, improving cotton yield and improving soil conditions.

Abstract

The invention discloses a salt-light alkali-reducing cultivation method for cotton in saline-alkali soil, and relates to the technical field of cotton planting. Comprising the following steps: deeply ploughing a cotton field, applying a base fertilizer, and irrigating to make entropy to obtain a to-be-sown cotton field; cotton sowing is carried out by adopting a direct-seeding plastic film mulching method and a machine-harvested cotton planting mode, the sowing depth is controlled to be 2.5-3.5 cm, the soil covering width is 5-7 cm, the soil covering thickness is 0.5-1 cm, the one-grain rate is larger than or equal to 95%, and the hole rate is smaller than or equal to 3%; after-sowing management is conducted in the cotton seedling stage, timely intertillage is conducted, and meanwhile leaf fertilizer is sprayed according to the cotton cotyledon stage to the two-leaf stage, the 3-4-leaf stage and the 4-leaf stage; performing water and fertilizer management in a cotton bud stage, performing intertillage, and performing foliage dressing at the same time; in the cotton flowering and boll-forming period, water dripping fertilizer is conducted according to the entropy condition, topping is conducted in good time, meanwhile, fertilizer is applied to regulate and control the plant type, and fertilizer is applied according to the premature senility trend and the snooze growth vigor; disease, pest and weed control is carried out in the sowing period. The cultivation method is suitable for saline-alkaline cotton fields in Xinjiang and is an effective means for increasing the cotton yield and improving soil conditions.
