Preparation method and application of crop straw organic fertilizer containing poly-Y-glutamicacid

Abstract

The invention discloses a preparation method of a crop straw organic fertilizer containing poly-Y-glutamicacid. According to the method, crop straw is used as a base material, a microorganism strain is added, high-temperature compost fertilization is matched with the effective component poly-Y-glutamicacid, and accordingly the crop straw organic fertilizer containing the poly-Y-glutamicacid is prepared. The preparation technology is simple, low in cost and high in controllability. The crop straw organic fertilizer containing the poly-Y-glutamicacid is high in yield, free of environmental pollution and balanced in nutrient content; and the crop straw organic fertilizer containing the poly-Y-glutamicacid contains major elements of nitrogen, phosphorus and potassium, and rich microelements and beneficial microorganisms, and under the synergistic effect of the poly-Y-glutamicacid, a good effect on improving soil, raising soil fertility and improving crop quality can be achieved. The crop straw organic fertilizer containing the poly-Y-glutamicacid prepared through the method can be applied to soil fertilization of vegetable crops, grain crops and commercial crops.

Description

technical field [0001] The invention belongs to the field of chemical fertilizer production, and in particular relates to a preparation method and application of a crop straw organic fertilizer containing Y-polyglutamic acid. Background technique [0002] The promotion of ecological agriculture and the protection of the ecological environment and farmland soil are becoming a research hotspot for environmental protection and agricultural science and technology personnel. However, with the increase in the use of chemical fertilizers, a series of problems have appeared while increasing the yield of crops: ordinary chemical fertilizers dissolve too quickly, decompose when heated, coupled with surface runoff, underground infiltration, unfavorable weather conditions, etc., fertilizer loss Seriously, the fertilizer utilization rate is low, which not only causes energy and resource waste and economic loss, but also causes serious pollution to the ecological environment such as water...

Problems solved by technology

However, with the increase in the use of chemical fertilizers, a series of problems have appeared while increasing the yield of crops: ordinary chemical fertilizers dissolve too quickly, decompose when heated, coupled with surface runoff, underground infiltration, unfavorable weather conditions, etc., fertilizer loss Seriously, the fertilizer utilization rate is low, which not only causes energy and resource waste and economic loss, but also causes serious pollution to the ecological environment such as water sources. The long-term use of chemical fertilizers will cause damage to the farmland ecosystem, soil physical and chemical properties and soil microbial system Severe damage, resulting in soil compaction

Crop straw contains a large amount of organic matter, nitrogen, phosphorus, potassium and trace elements, but most of the crop straw is directly discarded and burned, resulting in a huge waste of resources and serious pollution to the environment
