Embodiment Construction

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention will be further elaborated below.

[0020] A kind of cotton cultivation method in saline-alkali land, is characterized in that: comprise the following steps,

[0021] 1. Plowing and salt pressing: carry out deep plowing in spring and autumn, and plow once every 4 days;

[0022] 2. Use water pressure to salt: After plowing, water the furrows 25 days before sowing, and irrigate according to the salt content of the saline-alkali land. The amount of irrigation water with a salinity of 0.1%-0.3% is 40-50m 3 / mu, for every 0.3%-0.6 increase in salt content, the irrigation volume will increase by 5-10m 3 / mu, irrigate once every 6 days;

[0023] 3. Add organic fertilizer: Before sowing, apply 3000kg of coarse fertilizer, 15kg of urea, 20kg of diammonium phosphate, 15kg of potassium sulfate, 1kg of zinc sulfate, and 0.5k...

Abstract

The invention discloses a method for cultivating cotton in saline-alkali soil, and relates to the field of technologies for cultivating crops. The method is characterized by comprising steps of plowing the soil to press salt; pressing the salt by the aid of water; additionally applying organic fertilizers to the saline-alkali soil; sowing seeds in due time; covering the soil by mulching films; placing seedlings in the soil in due time; reducing branches of cotton and pruning the cotton; uncovering the mulching films timely, watering the cotton and applying additional fertilizers to the cotton; performing reasonable chemical control; timely performing insect disease prevention on the cotton. The method has the advantages of simplicity, clear steps and good cultivation effect.

Description

Technical field: [0001] The invention relates to the technical field of crop cultivation, in particular to a cotton cultivation method in saline-alkali land. Background technique: [0002] Cotton is the seed fiber of the Malvaceae cotton plant, native to the subtropical zone. The plant is shrubby and can grow up to 6 meters high in tropical areas, generally 1 to 2 meters. The flowers are milky white, turn dark red shortly after flowering and then wither, leaving small green capsules called cotton bolls. There are cottonseeds in the cotton bolls, and the fluff on the cottonseeds grows from the skin of the cottonseeds and fills the inside of the cotton bolls. When the cotton bolls mature, they crack, exposing soft fibers. The fibers are white or white with yellow, about 2 to 4 cm long, containing about 87 to 90% cellulose. [0003] The saline-alkali land is a type of salt accumulation, which means that the salt contained in the soil affects the normal growth of crops. The f...
