Special fertilizer for saline land peanut

Abstract

The invention discloses special fertilizer for saline land peanut. The special fertilizer is formed by blending organic fertilizer, inorganic fertilizer, an ameliorant, a water-retaining agent and a biological agent, and is characterized in that the organic fertilizer comprises the following components in weight ratio: 45 percent of fermental chicken droppings, 50 percent of crushed straw and 5 percent of wood vinegar; the weight of the organic fertilizer is 25 to 45 percent of that of the special fertilizer; the weight of the inorganic fertilizer is 35 to 55 percent of that of the fertilizer; the inorganic fertilizer is formed by mixing the following raw materials: urea, monoammonium phosphate, calcium magnesium phosphate fertilizer, potassium chloride, heptahydrate, boric acid and a filling material; the ratio of nitrogen to phosphorus to potassium contained in slow release micro element fertilizer is equal to 15:12:5.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a special fertilizer for peanuts in saline-alkali land. Background technique [0002] Peanut is an important food crop and is moderately sensitive to salt stress. Salt is one of the important environmental factors affecting the growth and development of peanut. Soil salinization accompanied by the process of industrialization and the scarcity of fresh water resources has become an urgent need for peanut cultivation today. One of the important difficulties to break through; salt damage is the main abiotic adversity that restricts peanut production. Under saline conditions, its yield decreases, and salt-sensitive varieties are more affected by salt stress than salt-tolerant varieties; at the same time, peanuts require fertilizer. Large-volume crops need about 8 million tons of fertilizer annually, accounting for 17-20% of China's fertilizer consumption. However, long-term single applicat...

[0002] Peanut is an important food crop and is moderately sensitive to salt stress. Salt is one of the important environmental factors affecting the growth and development of peanut. Soil salinization accompanied by the process of industrialization and the scarcity of fresh water resources has become an urgent need for peanut cultivation today. One of the important difficulties to break through; salt damage is the main abiotic adversity that restricts peanut production. Under saline conditions, its yield decreases, and salt-sensitive varieties are more affected by salt stress than salt-tolerant varieties; at the same time, peanuts require fertilizer. Large-volume crops need about 8 million tons of fertilizer annually, accounting for 17-20% of China's fertilizer consumption. However, 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 be significant. decrease, and the fertilizer efficiency of organic fertilizers is slow. At the same time, most of the crop straws, leaves, and weeds in the prior art are directly burned in the field to avoid affecting the cultivated land; although this treatment method is simple, it is harmful to the beneficial microorganisms in the soil. The damage is serious, which is not conducive to the growth of crops; in addition, the carbon in the straw accounts for the vast majority, followed by potassium, silicon, calcium, magnesium, sulfur, and phosphorus. The products after incineration mainly include CO2, CO, SO2, NO2 and N2O. Harmful gases enter the atmosphere and cause serious environmental pollution; if these straws are composted and returned to the field, they will become rich organic fertilizers to fertilize the soil and improve soil properties; the degradation of straw cellulose by microorganisms is through the free Cellulase, degrades cellulose by hydrolase mechanism and oxidase mechanism; the use of microorganisms can finally decompose cellulose into CO2 and H20, and the growth of microorganisms can produce a large amount of bacterial protein, so the use of microorganisms to treat straw , can greatly increase its nutritional value
