Abstract

The invention discloses humic acid compound fertilizer and a preparation method thereof. The humic acid compound fertilizer is prepared from raw materials in parts by weight as follows: 30-60 parts ofpond sludge, 10-20 parts of cow dung, 10-20 parts of straw, 5-10 parts of modified attapulgite, 3-5 parts of vermiculite powder, 15-25 parts of urea, 12-18 parts of manganese sulfate, 5-10 parts of potassium humate, 12-18 parts of zinc sulfate, 1-3 parts of EDTA (ethylene diamine tetraacetic acid) and 0.5-1.0 part of a silane coupling agent KH550. The humic acid compound fertilizer has positive effects on yield and quality of crops, has a function of improving soil, provides excellent growth environment for crops and realizes better economic benefits and ecological benefits.

Description

technical field [0001] The invention relates to the technical field of crop fertilizers, in particular to a humic acid compound fertilizer and a preparation method thereof. Background technique [0002] Fertilizer is a kind of substance that provides one or more essential nutrients for plants, improves soil properties, and improves soil fertility. It is one of the material basis of agricultural production. 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 ve...
