AI Technical Summary

Problems solved by technology

Soluble phosphate will form phosphate precipitation with dissolved calcium or iron ions in the soil, so that phosphorus is fixed and loses the meaning of water-soluble fertilizer
In addition, if the water-soluble compound fertilizer is dissolved in water, if the plants cannot absorb it in time, the soluble potassium ions and other nutrients will seep into the ground, which will not only cause the loss of fertilizer efficiency, but also pollute the groundwater.

Embodiment 1

[0045] 1) Add 7 parts of 4,4,-- bis stearamidodiphenyl ether hydrogel material and 60 parts of water into the reactor, stir, disperse and dissolve into a sol solution, and age for 20 minutes to form a gel;

[0046] 2) Add 50 parts of ammonium nitrate and 190 parts of potassium nitrate into the gel reaction kettle of step 1), stir, mix and disperse for 30 minutes, so that nitrogen and potassium fertilizers are fully absorbed in the organic hydrogel, dry and finely grind to obtain a gel Nitrogenous potassium fertilizer powder;

[0047] 3) Mix 40 parts of superphosphate, 160 parts of potassium chloride, 15 parts of chelated medium elements, 5 parts of chelated trace elements, 4 parts of sodium borate, 10 parts of growth promoter and the gelled nitrogen obtained in step 2) Potassium fertilizer was added to a high-speed mixer and stirred at high speed, mixed and dispersed for 30 minutes to obtain a slow-release water-soluble fertilizer specially used for bananas.

Embodiment 2

[0049] 1) Add 8 parts of cetyl iminodisaccharide hydrogel material and 70 parts of water into the reactor, stir, disperse and dissolve into a sol solution, and age for 30 minutes to form a gel;

[0050] 2) Add 60 parts of ammonium nitrate and 200 parts of potassium nitrate into the gel reaction kettle of step 1), stir, mix and disperse for 40 minutes, so that nitrogen and potassium fertilizers are fully absorbed in the organic hydrogel, dry and finely grind to obtain a gel Nitrogenous potassium fertilizer powder;

[0051] 3) Mix 50 parts of superphosphate, 170 parts of potassium chloride, 16 parts of chelated medium elements, 6 parts of chelated trace elements, 5 parts of sodium borate, 12 parts of growth promoter and the gelled nitrogen obtained in step 2) Potassium fertilizer was added to a high-speed mixer and stirred at high speed, mixed and dispersed for 30 minutes to obtain a slow-release water-soluble fertilizer specially used for bananas.

Embodiment 3

[0053] 1) Add 9 parts of hydrogel material and 80 parts of water into the reactor, stir, disperse and dissolve into a sol solution, and age for 30 minutes to form a gel;

[0054] 2) Add 60 parts of ammonium nitrate and 210 parts of potassium nitrate into the gel reaction kettle of step 1), stir, mix and disperse for 40 minutes, so that the nitrogen fertilizer and potassium fertilizer are fully absorbed in the organic hydrogel, dry and grind finely to obtain the gel Nitrogenous potassium fertilizer powder;

[0055] 3) Mix 100 parts of urea, 50 parts of superphosphate, 180 parts of potassium chloride, 17 parts of chelated medium elements, 7 parts of chelated trace elements, 6 parts of sodium borate, 13 parts of growth promoter and the obtained in step 2) Add the gelled nitrogen and potassium fertilizer into a high-speed mixer and stir at high speed, mix and disperse for 40 minutes to prepare a slow-release water-soluble fertilizer specially for bananas.

Abstract

The invention relates to a special slow release water-soluble fertilizer for banana, and a preparation method thereof. Raw materials of the special slow release water-soluble fertilizer comprise 50-70 parts of ammonium nitrate, 40-60 parts of calcium superphosphate, 190-220 parts of potassium nitrate, 160-190 parts of potassium chloride, 15-20 parts of chelated medium elements, 5-10 parts of chelated trace elements, 4-8 parts of sodium borate, 10-15 parts of a growth promoter, and 7-12 parts of an organic hydrogel material. The invention also relates to the preparation method of the water-soluble fertilizer. The special slow release water-soluble fertilizer has the advantages of comprehensive nutrition, slow release of nitrogen and potassium nutrients, realization of the content of organic matters of 1.66-1.94%, according with banana nutrition absorption rules, promotion and adjustment of the growth of the banana, improvement of the flavor, nutrition and quality of the banana fruits, prolongation of the storage time of the banana fruits, improvement of the banana planting benefit, and improvement of the fertilizer effect utilization rate of the water-soluble fertilizer.

Description

technical field [0001] The invention relates to a special slow-release water-soluble fertilizer for bananas and a preparation method thereof. More specifically, the invention relates to a slow-release water-soluble fertilizer special for bananas and a preparation method thereof, belonging to the field of special water-soluble fertilizers. Background technique [0002] Banana pulp is sweet and soft, and is one of people's favorite fruits, containing a lot of nutrients. Banana is one of the crops with large planting area and high economic benefits in my country, and it is one of the main pillar industries of tropical high-efficiency agriculture, occupying a pivotal position. According to statistics, in 2008, my country's banana harvested area was 317,800 hm2, ranking sixth in the world. In the same year, my country's total banana output was about 8.0427 million tons, accounting for 8.9% of the world's total output, second only to India (23.2048 million tons, accounting for 25...
