Problems solved by technology

[0004] The purpose of the present invention is to solve the problems that crops cannot grow normally due to boron deficiency in soil, and the common boron fertilizers have poor borax solubility, serious boric acid leaching loss, and low boron content in boron and magnesium fertilizers, and propose a slow-release boron fertilizer, while improving Soil pore structure, degradable environment-friendly boron fertilizer for improving soil water retention performance and preparation method thereof

Embodiment Construction

[0040] The present invention is described in further detail below in conjunction with embodiment.

[0041] The invention provides a preparation method of a degradable slow-release boron fertilizer that can slowly release boron fertilizer and has good water absorption and water retention performance, which will be described in conjunction with the examples below.

[0042] (1) Weigh 6.18g of boric acid and 19g of glycerin and place them in a beaker and mix them evenly, so that the boric acid is evenly dissolved in the glycerin.

[0043] (2) Put the mixed liquid obtained in step (1) in a microwave oven, and heat the esterification reaction at 210W for 6 minutes to obtain a glycerol complexed boron fertilizer, take it out, and place it in a desiccator to dry to room temperature.

[0044] (3) Weigh 3.82g of the product obtained in step (2), dissolve it in 2ml of pyridine solution and mix well. Add 15ml of dichloromethane to the mixed liquid, and stir well until the glycerol-comple...

Abstract

The invention discloses a slow-release boron fertilizer and a preparing method thereof. The slow-release boron fertilizer is prepared from boric acid, glycerol, acryloyl chloride, dichloromethane, pyridine, cyclohexane, carboxymethylcellulose, acrylic acid, potassium hydroxide, ammonium persulphate, sodium hydrogen sulfite, citric acid and sodium dihydrogen phosphate. The slow-release boron fertilizer prepared with method can be directly applied to soil when crops are seeded, the boron fertilizer can be slowly released into soil in the irrigation process, boron is supplemented for the crops, leaching loss of the boron fertilizer is decreased, and the using rate of the fertilizer is increased; meanwhile, the slow-release boron fertilizer can also have effects of preserving the moisture andfertilizer and improving soil pore structures, and promotes health growth of the crops. The slow-release boron fertilizer is degradable, and cannot pollute on soil.

Description

technical field [0001] The invention belongs to the technical field of agricultural slow-release fertilizers, and in particular relates to an agricultural slow-release boron fertilizer and a preparation method thereof. Background technique [0002] Boron is one of the essential trace elements for crop growth and development. It plays an important role in the transformation and transportation of carbohydrates in crops, the formation and development of reproductive organs, the normal differentiation of meristem cells and stress resistance. Soil boron deficiency will cause problems such as poor growth of crop leaves, stems, growth points, flowers, fruits, etc., seriously affecting the yield and quality of crops. There is a problem of boron deficiency in the soil of our country, which seriously limits the production of rapeseed, sugar beet, cotton, peanut, soybean and other crops in our country. At present, the common boron fertilizers in my country mainly include borax, boric ...
