AI Technical Summary

Problems solved by technology

The above-mentioned fertilizer has a single nutrient component and has no slow-release function. After application, it decomposes quickly, and only a small amount is absorbed by crops. The fertilizer utilization rate is only between 25% and 35%, and the rest of the nutrients are volatilized or washed away by rainwater. Nutritional pollution seriously endangers the environment and people's health
In addition, the above-mentioned fertilizers are very lethal to the seeds and their young shoots, and farmers have to carry out multiple fertilization
First of all, it is necessary to apply base fertilizer in the soil before sowing the crops and then sow them, and then topdress the crops in the early and middle stages of growth, which is time-consuming and laborious, and is easily restricted by rainwater

Abstract

The invention relates to a polypeptide humic acid chelate sustained-release fertilizer, which consists of the following ingredients in part by weight: 95 to 110 parts of potassium chloride, 170 to 185 parts of monoammonium phosphate, 15 to 25 parts of ammonium bicarbonate, 240 to 260 parts of ammonium sulfate, 260 to 280 parts of urea, 80 to 95 parts of humic acid, 35 to 45 parts of boron calcium powder, 3 to 8 parts of zinc sulphate heptahydrate, 15 to 30 parts of amino acid, 2 to 5 parts of sodium molybdate dehydrate, 1 to 5 parts of chelator, 8 to 15 parts of polypeptide sustained-release agent and 3 to 8 parts of film coating agent. A preparation process comprises the following steps of: mixing and stirring the ingredients in a ratio to obtain powder; and conveying the powder into a granulating machine for granulating, drying, cooling and sieving to obtain the finished product. The polypeptide humic acid chelate sustained-release fertilizer has the advantages of economy, environment friendliness and the like, labor and time are saved, and a preparation method is simple.

Description

Technical field [0001] The invention relates to the technical field of fertilizer science related to plant nutrition, and particularly provides a polypeptide humic acid chelated slow-release fertilizer. Background technique [0002] At present, most of our country's crops such as wheat, corn, rice, rape, flowers, etc. use single nitrogen fertilizer or compound fertilizer or compound fertilizer containing only nitrogen, phosphorus and potassium. The above-mentioned fertilizers have a single nutrient composition and no slow-release function. They decompose quickly after application, and only a small amount is absorbed by crops. The fertilizer utilization rate is only between 25% and 35%. The rest of the nutrients are volatilized or washed away by rainwater, thus causing river water bodies. Nutritional pollution seriously endangers the environment and people's health. In addition, the above-mentioned fertilizers have great lethality on seeds and their sprouts, and farmers have to a...
