Problems solved by technology

In particular, according to relevant data reports and market surveys, fake and inferior boron fertilizers, mainly "boron and magnesium fertilizers", are flooding the market, which not only damages the interests of farmers, but also further aggravates the lack of boron in the soil.
Rapeseed, cotton, melon, fruit, vegetables and other crops that require a large amount of boron, due to boron deficiency in the soil and improper or no boron fertilizer application, yield reduction, crop failure, and quality decline occur from time to time, which seriously restricts the high yield of agricultural production in our country , high quality and efficient development

preparation example Construction

[0041] Refer to accompanying drawing and know: the preparation method of ammonium borate foliar fertilizer of the present invention is characterized in that it comprises the steps successively:

[0042] ①Heat 60 kg of water in the reactor to 60°C, then put 50 kg of boric acid and 50 kg of ammonium water into the reactor, and stir while adding until no bubbles come out. The reaction formula is: NH 4 OH+H 3 BO 4 →(NH 3 ) 4 BO 4 +H 2 O;

[0043]②Then transfer the solution to the electric heating evaporator to evaporate and concentrate to 50%. The temperature in the electric heating evaporator does not exceed 100°C, filter out the supernatant liquid, and cool to room temperature to crystallize;

[0044] ③The crystals are dehydrated and then transferred to a dryer for drying at a drying temperature of 100-105°C for 8 hours to obtain a polymerized ammonium borate foliar fertilizer.

[0045] If it is necessary to prepare powdery polymeric ammonium borate foliar fertilizer, the...

Abstract

This invention discloses a method for preparing leaf fertilizer of poly (ammonium borate). The method comprises: (1) heating 60 kg water in the reaction kettle to 60 deg.C, and adding 50 kg boric acid and 50 kg ammonia under stirring until no air bubbles; (2) evaporating and concentrating the solution in an electric evaporator at less than or equal to 100 deg.C to 50%, filtering the supernatant, cooling to normal temperature, and crystallizing; (3) dehydrating the crystal, and drying in a drier at 100-105 deg.C for 8 h to obtain the leaf fertilizer of poly(ammonium borate). The leaf fertilizer of poly (ammonium borate) has such advantages as high boron content, easy absorption, and low crystallinity.

Description

technical field [0001] The invention relates to a fertilizer for crops, more specifically a polymerized ammonium borate foliar fertilizer, and also relates to a preparation method of the polymerized ammonium borate foliar fertilizer. Background technique [0002] In my country's chemical fertilizer industry products, since the 1960s and 1970s, the fertilizer industry and products such as nitrogen fertilizer, phosphate fertilizer, potash fertilizer, compound (compound) fertilizer, organic-inorganic compound fertilizer, boron fertilizer, and zinc fertilizer have been greatly developed. . These fertilizer products have been widely used in agricultural production and have played a huge role in promoting my country's agricultural production. [0003] In my country's agricultural production, it is currently used as an agricultural boron trace element fertilizer, and the industrial raw material borax, namely disodium tetraborate decahydrate (Na 2 B 4 o 7 10H 2 O), because it co...
