Organic fertilizer

Abstract

The invention relates to organic fertilizer. The organic fertilizer is prepared from the following components in parts by weight: 53 to 77 parts of an organic fermented matter, 20 to 35 parts of fowlmanure, 10 to 25 parts of oil residues, 5 to 20 parts of zeolite powder, 3 to 10 parts of urea, 2 to 8 parts of acid, 8 to 12 parts of potassium dihydrogen phosphate, 3 to 8 parts of coal, 1 to 3 parts of zinc sulfate, 17 to 20 parts of carbon fertilizer and 13 to 27 parts of animal manure. The organic fertilizer has the advantages of low cost, simple production technology and remarkable fertilizer efficiency; the organic fertilizer can be used as basic fertilizer and additional fertilizer, can meet the nutrient requirements of crops and has a remarkable yield increasing effect; the yield increasing rate per Mu of various crops can reach 20 to 50 percent; and the content of organic matters in soil can be increased, a soil structure is improved and the fertilizer retention and fertilizer supply capabilities of the soil are improved.

Description

technical field [0001] The invention belongs to the field of agricultural fertilizers, in particular to an organic fertilizer. Background technique [0002] At present, most of the agricultural fertilizers use urea and potassium chloride, which have a single component. The compound (mixed) fertilizer is a two-element or multi-element mixed fertilizer, but it is still an inorganic fertilizer. It lacks potassium, one of the three essential elements for crops. The lack of potassium has become a key factor restricting the increase in grain and fruit production. There are also some compound (mixed) fertilizers. Although they do not lack the three major elements of nitrogen, phosphorus, and potassium or some trace elements, their nitrogen is in an inorganic form. After entering the soil, it cannot directly participate in synthesis or storage, but when it is absorbed and assimilated by crops , but also consume a lot of energy, long-term use of inorganic fertilizers will lead to a ...

The compound (mixed) fertilizer is a two-element or multi-element mixed fertilizer, but it is still an inorganic fertilizer. It lacks potassium, one of the three major elements necessary for crops. The lack of potassium has become a key factor restricting the increase in grain and fruit production.

There are also some compound (mixed) fertilizers. Although they do not lack the three major elements of nitrogen, phosphorus, and potassium or some trace elements, their nitrogen is in an inorganic form. After entering the soil, it cannot directly participate in synthesis or storage, but when it is absorbed and assimilated by crops , but also consume a lot of energy, long-term use of inorganic fertilizers will lead to a decline in soil organic matter content, soil compaction, soil fertilizer retention and fertilizer supply capacity reduction and other adverse phenomena, so that it will affect the future crop yield and agricultural production stamina play
