Special soybean fertilizer capable of enhancing nitrogen utilization ratio

Abstract

The invention discloses a special soybean fertilizer capable of enhancing nitrogen utilization ratio. The fertilizer is prepared from the following raw materials in parts by weight: 2-3 parts of nitrogin, 6-8 parts of cigarette rag, 44-48 parts of vinasse, 6-7 parts of weathered coal, 0.6-0.8 part of xylitol, 3-4 parts of ammonium molybdate, 4-5 parts of calcium carbonate powder, 1-2 parts of quartzite powder, 20-22 parts of waste newspaper, 2-3 parts of potassium persulfate, 30-33 parts of yellow meal worm manure, 0.7-1.0 part of ferric chloride, 0.5-0.6 part of ammonium ferrous sulfate hexahydrate, a right amount of 25% phosphoric acid solution and a right amount of water. The fertilizer is composed of the reasonably prepared raw materials according to the fertilizer demand rules of the soybeans. The nitrogin is added to implement the generation of the soybean root system symbiotic root nodules. The ammonium molybdate and other nitrogen components are properly added, thereby supplementing the demand for nitrogen in case of a small amount of rhizobia in the earlier period, and avoiding the excessive nutrient waste caused by abundant nitrogen fixation of rhizobia in the later period. The nitrogin and nitrogen components regulate the nitrogen demand of the soybeans under the synergic actions, thereby enhancing the nitrogen utilization efficiency.

Description

Technical field [0001] The invention relates to the technical field of fertilizers, in particular to a special fertilizer for soybeans that improves nitrogen utilization. Background technique [0002] my country is a large agricultural country, and the use of fertilizers is extremely high. The current fertilizer and its corresponding fertilization technology have kept the fertilizer utilization rate in my country at a low level for a long time, which has seriously affected farmers' enthusiasm for planting and caused serious pollution to the environment. , It is not conducive to the construction of an efficient and high-yielding modern industrial technology system for sustainable development in my country. Based on national food safety requirements and high-yield targets, the use of chemical fertilizers has continued to increase. Some farmers' blind fertilization has caused soil, water quality, and crop pollution, reduced fertilizer efficiency, and increased food costs. Therefore,...

If these insect droppings are not handled properly, it will not only cause waste of resources, but also pollute the environment. How to make good use of insect droppings has aroused people's attention

At present, insect manure has been used as organic fertilizer, animal feed and cultivated edible fungus, etc., but these applications are only simple applications of insect manure, and the added value is not high
