Microbial fertilizer applicable to improvement of soda alkalized and salinized areas in northeastern China

Abstract

The invention relates to a microbial fertilizer applicable to improvement of soda alkalized and salinized areas in northeastern China. The microbial fertilizer comprises 1-1.5 of pentaerythritol, 10 to 15 of biochemical fulvic acid, 10-16 of trans-butenedioic anhydride, 30 to 40 of an amino acid solution with a concentration of 50%, 2 to 3 of calcium phosphide, 1 to 3 of magnesium sulfate, 15 to 20 of potassium permanganate, 8 of Bacillus amyloliquefaciens, 6 of Thiobacillus thiooxidans, 4 of nitrogen-fixing bacteria and 2 of yeast. Directed at the characteristics of soil in soda alkalized andsalinized areas in northeastern China, pentaerythritol, biochemical fulvic acid and trans-butenedioic anhydride are used for regulating the formation and shaping of soil granules; calcium phosphide,magnesium sulfate and potassium permanganate are used for balancing salt ion trends in granular soil; Bacillus amyloliquefaciens, Thiobacillus thiooxidans, nitrogen-fixing bacteria and yeast loosen soil through proliferative activity; Bacillus, Thiobacillus and a pentaerythritol composting product are directed at alkalized soil with soda characteristics in northeastern China, and have substantialcontrol and regulation effect on fertilizer retention, fertilizer supply, water retention, water supply and air breathability.

Description

technical field

[0001] The invention relates to the technical field of fertilizers, in particular to an improvement microbial fertilizer suitable for soda alkalization and saline areas in Northeast China. Background technique

[0002] Soil characteristics of soda alkalized and saline areas in Northeast China: Soil in soda alkalized and saline areas in Northeast China belongs to the inland soda saline type, with soda (Na 2 CO 3 ) and baking soda (NaHCO 3 ) mainly. This type of soil has different degrees of salinization and alkalization characteristics. The average soil pH is between 8.8 and 9.2, with strong alkalinity and basic Na + , K + The content is not much different from that of the cultivated land, and the cultivated land is the most, but the content of Mg2+ and Ca2+ is significantly higher than that of the cultivated land, and the relationship between sodium salt hazard and ion balance is out of balance. The advantage of microbial fertilizer is that it can form a...
