Wheat straw compound fertilizer for slowly releasing drought stress

Abstract

The invention discloses a wheat straw compound fertilizer for slowly releasing drought stress. The wheat straw compound fertilizer is prepared from the following components in parts by weight: 1000 parts of dry straws, 2000 parts of biogas slurry, 400-500 parts of urea, 60-90 parts of monopotassium phosphate, 80-110 parts of boric acid, 40-50 parts of chromium trichloride, 40-50 parts of manganese chloride, 100-120 parts of zinc sulfate, 2-5 parts of SA (salicylic acid), 2-5 parts of ethephon, 20-30 parts of polyaspartic acid, 15-20 parts of trichodermaspp, 9-15 parts of micromonospora and 20-30 parts of polyangium cellulosum. The wheat straw compound fertilizer is prepared through the following steps of: selecting biogas slurry; implementing microorganism treatment; implementing aerobic fermentation; implementing anaerobic fermentation; adding boric acid, chromium trichloride, manganese chloride, zinc sulfate, SA, ethephon and polyaspartic acid in a fermentation tank and evenly mixing to form a mixture; bagging and packaging the mixture.

Description

technical field [0001] The invention relates to a wheat fertilizer, in particular to a wheat straw compound fertilizer for slow release of drought stress. Background technique [0002] Drought stress has an extremely serious impact on agricultural production, and its damage is equivalent to the sum of other natural disasters. Therefore, exploring ways to improve plant drought resistance has always been one of the hotspots of scientific researchers. Due to soil drought or atmospheric drought, wheat roots The water absorbed from the soil is difficult to compensate for the consumption of transpiration, which makes the water balance in the plant imbalance, seriously affects the normal growth and development of wheat and even dies, and eventually leads to reduced yield and quality. [0003] Long-term single application of chemical fertilizers will cause long-term problems such as soil compaction, nutrient imbalance, and poor physical properties, and the production capacity will d...

[0002] Drought stress has an extremely serious impact on agricultural production, and its damage is equivalent to the sum of other natural disasters. Therefore, exploring ways to improve plant drought resistance has always been one of the hotspots of scientific researchers. Due to soil drought or atmospheric drought, wheat roots The water absorbed from the soil is difficult to compensate for the consumption of transpiration, which makes the water balance in the plant imbalance, seriously affects the normal growth and development of wheat and even dies, and eventually leads to reduced yield and quality.

[0003] Long-term single application of chemical fertilizers will cause long-term problems such as soil compaction, nutrient imbalance, and poor physical properties, and the production capacity will drop significantly, and the fertilizer efficiency of organic fertilizers will be slow. Burn directly in the field to avoid affecting the cultivated land; although this treatment method is simple, it seriously damages the beneficial microorganisms in the soil and is not conducive to the growth of crops; in addition, the carbon in the straw accounts for the vast majority, followed by potassium, silicon, and calcium , magnesium, sulfur, phosphorus, and the products after incineration mainly include CO 2 , CO, SO 2 , NO 2 and N 2 O, these harmful gases have caused serious environmental pollution after entering the atmosphere; if these straws are composted and returned to the field, they will become rich organic fertilizers to fertilize the soil and improve soil properties; microbial degradation of straw cellulose is through secretion into the cell External free cellulase, which degrades cellulose by hydrolase mechanism and oxidase mechanism; the use of microorganisms can finally decompose cellulose into CO 2 and H 2 0, and a large amount of bacterial protein can be produced through the growth of microorganisms themselves, so the use of microbial methods to treat straw can greatly improve its nutritional value; polyaspartic acid is a polymer of amino acids, a water-soluble polypeptide , biodegradable, has a certain biological activity, it acts as a fertilizer synergist, can absorb and enrich the elements in the soil that are beneficial to plant growth, and can improve the utilization rate of fertilizers
