[0043] Example 2 Germination experiment of Chinese cabbage

[0044]In normal soil (0-35cm soil layer of vegetables in Wenshang County, Jining City, Shandong Province, the soil salt content is 0.22%), saline-alkali soil (collected from 0-35cm surface saline-alkali soil in Aksu area, Xinjiang, the soil salt content On 2.05%~2.50%), treated saline-alkali soil (using the product and method for improving soil salinity in Example 1 to process saline-alkali soil, dilute 1000 times, and treat 3 times altogether, each interval is 5 days) Plant pakchoi (the variety is Shanghai Green), select a few pakchoi seeds with full grains and the same size, plan to plant 25 seeds in each pot, fill the experimental soil to a distance of 1-2cm from the edge, and sprinkle 25 pakchoi evenly seeds, and sprinkle 3-5mm of experimental soil on top, just cover the seeds, pour water until the soil is thoroughly watered after planting, and water once a day, the temperature is 18-25°C, and the scattered light...

Abstract

The invention discloses a microbial agent for improving soil salinization, which comprises the following components in parts by weight: 85-90 parts of rhodopseudomonas palustris or a culture thereof, 0.1-0.3 part of polyacrylamide, 5-10 parts of polyglutamic acid, 1-3 parts of amino acid powder and 1-2 parts of hydrolyzed polymaleic anhydride. The effective live bacteria count in the rhodopseudomonas palustris or the culture thereof is 2*10<8>-1*10<9>/ml. The microbial agent for improving the soil salinization can effectively improve the quality of the salinized soil, reduce the salinization, reduce the EC value of the soil, promote seed germination and promote plant growth. Tests prove that the microbial agent for improving the soil salinization can reduce the conductivity and pH of the salinized soil, improve the granular structure of the soil, increase the germination rate of pakchoi and effectively improve the salinized soil.

Description

technical field [0001] The invention relates to a microbial bacterial agent for improving soil salinization, which belongs to the technical field of soil improvement. Background technique [0002] Soil salinization refers to the process in which the salt in the bottom soil or groundwater rises to the surface with capillary water, and after the water evaporates, the salt accumulates in the surface soil. It refers to the phenomenon or process in which soluble salt accumulates on the soil surface, also known as salinization. China's saline soil or saline-alkali soil has a wide distribution range, a large area, and many types, with a total area of ​​about 100 million hectares. It mainly occurs in arid, semi-arid and sub-humid regions. The soluble salts of saline-alkali soil mainly include sulfate, chloride, carbonate and bicarbonate of sodium, potassium, calcium, magnesium, etc. Sulfates and chlorides are generally neutral salts, and carbonates and bicarbonates are alkaline s...
