Abstract

The invention provides a method for planting cotton in low-lying saline-alkali soil. Through a mode of embedding concealed pipes, digging a water treatment pit to perform water filtration and salt separation and digging a water-collecting well to underground water to perform drainage, the problems of salt damage and waterlogging damage in low-lying saline-alkali soil districts are solved. A specially-made microbial fertilizer is adopted, so that the cotton agricultural damage is little, and the yield is high. Carbendazim and gibberellin are combined, gibberellin can improve the seed germination rate, can stimulate leaf and bud growth; carbendazim is a bactericide and can kill germs carried by seeds and germs carried in peripheral soil after seeding; and carbendazim and gibberellin are combined to perform mutual synergism, so as to improve rate of emergency, prevent diseases at a seedling stage and improve cotton yield.

Description

technical field [0001] The invention relates to the technical field of improving saline-alkali land, in particular to a method for planting cotton in low-lying saline-alkali land. Background technique [0002] Saline-alkali land is the general term for salt land and alkaline land. Saline soil mainly refers to salinized soil with high chloride or sulfate content. The soil is alkaline, but the pH value is not necessarily high. Alkaline soil refers to the soil containing carbonate or heavy phosphate, the pH value is high, and the soil is alkaline. The content of organic matter in saline-alkali land is low, the soil fertility is low, the physical and chemical properties are poor, and there are many anions and cations harmful to crops, so it is difficult for crops to promote seedlings. The area of ​​saline-alkali land in the world is 954.38 million hectares, of which 99.13 million hectares are in my country. The formation of alkaline land and alkalized soil in my country is mo...
