Abstract

The invention relates to a coastal sandy soil saline land soil modifier and applications of the coastal sandy soil saline land soil modifier in sorghum-sudangrass hybrid planting. The present invention discloses a coastal sandy soil saline land soil modifier, which comprises, by mass, 30-35 parts of organic fertilizer cow manure, 8-10 parts of potassium feldspar, 3-5 parts of hydrolyzed polyacrylonitrile, 1-3 parts of asparagus officinalis residue, 3-5 parts of boric acid, 7-10 parts of sawdust, 12-15 parts of fulvic acid, 6-8 parts of biochar, 5-7 parts of polyvinyl alcohol, 3-5 parts of polymeric amino acid, 0.6-0.8 part of a soil thickener, 3-8 parts of gaillardia pulchella foug powder, 7-9 parts of Yeqiexiang, 0.2-0.8 part of a water retaining agent, 0.05-0.07 part of Bacillus coagulans, and 0.2-0.6 part of halophilic methane bacteria. According to the present invention, 12 months after the sorghum-sudangrass hybrid is planted, the pH value of the soil is 7.0-7.3, the soil alkalinity is 1.8-2.5%, the soil salt content is 0.11-0.18%, and the soil water holding capacity is 42-47%.

Description

technical field [0001] The invention provides a soil improver for coastal sandy saline-alkali land and its application in planting Sorrel grass, which belongs to the technical field of soil improvement. Background technique [0002] The fundamental reason for the formation of saline-alkali soil is poor moisture status, so in the early stage of improvement, the focus should be on improving the soil moisture status. The main feature of saline-alkali land is that it contains more water-soluble salt or alkaline substances. The principle of improving saline-alkali land is to actively fertilize the soil while draining, separating and preventing salt. The main measures are: [0003] 1. Drainage [0004] For low-lying saline-alkali land. By digging drainage ditches, surface water can be drained away to remove some of the soil salt. [0005] 2. Wash salt with water [0006] According to the law of "salt comes with water, salt goes with water", water is poured into the ground to f...
