Abstract

The invention discloses a wheat dedicated composite coated fertilizer which is characterized by being prepared from the following raw materials in parts by weight: 34-40 parts of a castor cake, 18-25 parts of a rapeseed cake, 22-25 parts of wheat bran, 10-13 parts of a fishbone powder, 6-8 parts of clay, 100-110 parts of dry cow dung, 24-30 parts of bagasse, 1-2 parts of polyglutamic acid, 2-3 parts of urea formaldehyde, 35-40 parts of urea, 33-40 parts of ammonium phosphate, 18-24 parts of potassium chloride, 2-3 parts of ferrous sulfate, 6-8 parts of an EM agent, 8-10 parts of a soil improvement agent, and a proper amount of water. The fertilizer is reasonable in formula, more comprehensive and balanced in nutrition, and good in use effect; coating can play the sustained release role, and the fertilizer efficiency is allowed to be slowly released; moreover, with addition of polyglutamic acid, water and fertilizer retention abilities are improved, soil organic matters are increased, the fertilizer efficiency utilization rate can be significantly improved, the wheat yield and quality are greatly improved, and thus economic benefits of winter wheat are improved.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a special compound coated fertilizer for wheat and a preparation method thereof. Background technique [0002] Fertilizer is a type of substance that provides one or more essential nutrients for plants, improves soil properties, and increases soil fertility. There are many types of fertilizers, including chemical fertilizers such as nitrogen, phosphorus, and potassium, organic fertilizers such as soybean meal, animal manure, and agricultural waste, biological fertilizers such as biological bacteria, and medium and trace elements such as silicon, magnesium, iron, boron, and selenium. Fertilizers are varied. Different crops have different requirements for fertilizers due to different growth habits and different growth stages. Therefore, it is necessary to combine different crop varieties and study different fertilizers. It is very necessary to improve the quality and quality of crops. I...
