Organic compound fertilizer

Abstract

The invention discloses an organic compound fertilizer. The organic compound fertilizer is prepared by mixing the following components by weight: 8 to 15% of a bean cake, 6 to 20% of urea, 8 to 15% of pig manure, 10 to 20% of straw powder and 10 to 15% of ferrous sulphate, with the balance being fly ash. According to the invention, since organic matters like the bean cake, pig manure and straw powder are added, more nutrient elements are provided for growth of crops, fertilizer efficiency is prolonged, and soil properties are improved; since fly ash is used as a filling material, the organic compound fertilizer is applicable to a variety of acidic and alkaline soils; moreover, elemental composition of the organic 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 an organic compound fertilizer suitable for field crops with long fertilizer effect and complete crop nutrient elements. Background technique [0002] With the development and popularization of scientific farming technology, farmers have higher and higher requirements for the quality of chemical fertilizers. Elemental chemical fertilizers are no longer suitable for the needs of scientific farming. Most of the currently used compound fertilizers are ammonium bicarbonate, ammonium nitrate and other compound fertilizers. Practice has proved that the application of these waste materials alone is far from meeting the requirements of farmland soil for nitrogen, phosphorus and potassium, and some soil is not suitable for these compound fertilizers. Long-term application will cause soil hardening and reduce production. Summary of the invention [0003] In view of the shortcomings of the prior art, the ...
