Long-acting high-concentration compound fertilizer

Abstract

The invention discloses a long-acting high-concentration compound fertilizer which is formed by mixing the following components in percentage by weight: 10-15 percent of ammonium bicarbonate, 10-20 percent of potassium sulphate, 10-20 percent of ammonium phosphate, 3-5 percent of raw bone meal, 10-15 percent of pig manure and the balance being yellow phosphorus slag. With the raw bone meal, the pig manure and other organic matters, elements required by crops are complete, and the proportion of nitrogen, phosphorus and potassium, which are necessary for the growth of crops, is reasonable, the soil environment can be improved, the fertilizer retaining capability is improved, and the fertilizer efficiency is long.

Description

Technical field [0001] The present invention involves a compound fertilizer, especially for a long -term and high concentration compound fertilizer with long -lasting fertilizers suitable for large field crops and complete crop nutrition elements. Background technique [0002] Nitrogen, phosphorus, and potassium are the main elements that affect plant growth. The fertilizers currently used for crops are mainly inorganic nitrogen fertilizer, inorganic phosphate fertilizer and inorganic potassium fertilizer. Inorganic nitrogen fertilizer is mainly urea, ammonium bicarbonate, ammonium nitrate sulfate, etc., and inorganic phosphate fertilizer is mainly due toCalcium phosphate, hydrogen -phosphate dilate, etc., inorganic potassium fertilizer is mainly potassium sulfate, potassium chloride, etc. The above -mentioned inorganic fertilizers, long -term application, will cause soil plates, harsh soil environment, affect the output of crops, and the element required by crops is single., Aff...

[0002] Nitrogen, phosphorus, and potassium are the main elements that affect plant growth. Currently, the fertilizers used for crops are mainly inorganic nitrogen fertilizers, inorganic phosphorus fertilizers, and inorganic potassium fertilizers. The inorganic nitrogen fertilizers are mainly urea , ammonium bicarbonate, ammonium nitrate, ammonium sulfate, etc. Inorganic phosphate fertilizers are mainly calcium superphosphate, diammonium hydrogen phosphate, etc. Inorganic potassium fertilizers are mainly potassium sulfate, potassium chloride, etc. The long-term application of the above inorganic fertilizers will cause soil compaction and make the The soil environment is bad, which affects the yield of crops, and the elements required by crops are single, which affects the growth of crops
