Abstract

The invention provides a humic acid chelated boron, magnesium, zinc and iron fertilizer and a preparation method thereof. The fertilizer is composed of the following components in parts by weight: 20 to 30 parts of urea, 10 to 15 parts of diammonium hydrogen phosphate, 10 to 15 parts of potassium sulfate, 30 to 40 parts of boron magnesium slag, 10 to 15 parts of humic acid, 12 to 15 parts of citric acid, 1 to 2 parts of ammonia borate, 6.5 to 8 parts of magnesium sulfate, 7 to 7.5 parts of zinc sulfate, 5 to 6.5 parts of ferrous sulfate, 1 to 2 parts of avermectin, and 0.3 to 0.4 part of diazinon. The preparation method comprises the following steps: preparing medium trace element chelated fertilizer from citric acid, ammonium borate, magnesium sulfate, zinc sulfate, ferrous sulphate and humic acid, then adding urea, diammonium hydrogen phosphate, potassium sulfate, and boron magnesium slag into the fertilizer, grinding, and carrying out a spraying granulation process by using a mixed solution of avermectin and diazinon so as to obtain the finished product. The fertilizer has the advantages of high utilization rate of trace elements, reduction on soil hardening and water pollution, sustain-released effect, and longer lasting drug effect and fertilizing effect.

Description

technical field [0001] The invention relates to a humic acid chelated boron-magnesium-zinc-iron medicinal fertilizer and a preparation method thereof. Background technique [0002] In agricultural production, in order to increase the yield of crops, it is necessary to apply fertilizers to provide the nutrients necessary for the growth of crops. The fertilizers on the market are mainly nitrogen, phosphorus, and potassium macronutrient fertilizers. Studies have shown that medium and trace elements such as boron, zinc, iron, magnesium, and molybdenum are also necessary nutrients for crop growth. Once they are deficient, they will also affect the growth of crops. Therefore, , When planting in farmland, proper application of fertilizers containing trace elements has attracted people's attention. [0003] At present, compound fertilizers containing medium and trace elements are prepared by adding inorganic salts or oxides of medium and trace elements to nitrogen, phosphorus a...
