Compound fertilizer capable of improving soil environment

Abstract

The invention discloses a compound fertilizer capable of improving a soil environment. The compound fertilizer is prepared by mixing the following components by weight: 10% of diammonium phosphate, 9% of potassium chloride, 12% of straw powder and 15% of ammonium bicarbonate, with the balance being fly ash. According to the invention, since components like fly ash and straw powder are added, more nutrient elements are provided for growth of crops, and the problem of soil hardening is effectively improved; through addition of potassium chloride, ammonium bicarbonate and diammonium phosphate, elements needed by the crops are enriched, the compound fertilizer is applicable to a variety of acidic and alkaline soils; moreover, elemental composition of the compound fertilizer is reasonable, so good yield and income increasing effects are obtained.

Description

technical field [0001] The invention relates to a compound fertilizer, in particular to a compound fertilizer which can effectively improve soil environment and increase organic matter. Background technique [0002] With the development and popularization of scientific farming technology, farmers have higher and higher requirements for the quality of chemical fertilizers. Simple chemical fertilizers can no longer meet the needs of scientific farming. Most of the compound fertilizers currently used are compound fertilizers such as ammonium bicarbonate and ammonium nitrate. Practice has proved that the single application of these waste materials is far from meeting the needs of farmland soil for nitrogen, phosphorus and potassium, and long-term use of chemical fertilizers will cause soil compaction and organic matter reduction, greatly affecting crop yields. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the technical problem to be solved by ...
