Abstract

The invention discloses an organic-inorganic sustained-release compound fertilizer applied at one time. The fertilizer is prepared by mixing treated nitrogen, phosphate and potash fertilizers with sustained release performance with common nitrogen, phosphate and potash fertilizers and organic matters, wherein the treated nitrogen, phosphate and potash fertilizers are a product after polymerization of urea and formaldehyde and polymerization of monoammonium phosphate and potassium chloride. The production method for the fertilizer comprises the following steps of: 1, preparing a sustained-release nitrogen fertilizer or a sustained-release phosphorus potassium fertilizer; 2, uniformly mixing a base fertilizer, the sustained-release nitrogen fertilizer or the sustained-release phosphorus potassium fertilizer, organic matters and trace element materials; and 3, granulating, drying and sieving the uniformly mixed materials by using the conventional method to obtain the organic-inorganic sustained-release compound fertilizer. The sustained-release compound fertilizer can provide balanced nutrients required according to growth periods of different crops, and is applied at one time during plantation to meet the requirements of crops on different nutrients in the whole growth period, the utilization efficiency of the fertilizer and the quality of agricultural products are improved, the labor cost is saved and the yield is promoted to be increased.

Description

technical field [0001] The invention relates to fertilizers, in particular to compound or mixed fertilizers of nitrogen, phosphorus and potassium, especially to compound fertilizers with slow-release properties. Background technique [0002] The existing organic-inorganic compound fertilizer production is mostly made of oil dry, poultry manure, humic acid, crop straw, etc. It has obvious effect on effectively absorbing and improving the quality of agricultural products and increasing farmers' production and income. However, the effective elements of nitrogen, phosphorus, and potassium dissolve quickly in the soil moisture after application, which is not conducive to the balanced absorption and utilization of crops during the growth period, and is easily washed away by rainwater to pollute rivers and lakes, destroy the ecological environment, and also reduce the use of fertilizers. The effective utilization rate increases the cost of agricultural production. [0003] In vie...
