Problems solved by technology

[0003] Controlled-release nitrogen fertilizers have a significant effect on promoting the growth and development of garlic, but most of the controlled-release blended fertilizers currently used in production use a controlled-release period, and the nitrogen release law cannot fully match the growth and development of garlic. Reasonable collocation is better
In addition, due to the need for fruit expansion in the middle and late stages of garlic, the demand for potassium is higher than that for nitrogen, and the controlled release of nitrogen alone cannot fully meet the growth needs. Can meet the needs of garlic development

Embodiment 1

[0051] The masterbatch is activated humic acid 100kg, urea 120kg, monoammonium phosphate 260kg, potassium sulfate 300kg, ammonium sulfate 100kg, zinc sulfate heptahydrate 13kg, borax 16kg, gamma-polyglutamic acid 10kg for mixed granulation in parts by weight. After the granulation is completed, masterbatch 560kg is calculated in parts by weight, 120kg of resin-coated urea for 2 months of controlled release period, 120kg of resin-coated urea for 4 months of controlled-release period, and 200kg of resin-coated potassium chloride are blended to obtain garlic crops Special functional nitrogen and potassium double control fertilizer.

Embodiment 2

[0053] The master batch is calculated by weight to activate 100kg of humic acid, 100kg of urea, 300kg of monoammonium phosphate, 325kg of potassium sulfate, 150kg of ammonium sulfate, 10kg of zinc sulfate heptahydrate, 15kg of borax, and 30kg of γ-polyglutamic acid for mixing and granulation. After the completion, 600kg of masterbatch, 100kg of resin-coated urea for 2 months of controlled release period, 100kg of resin-coated urea for 4 months of controlled-release period, and 200kg of resin-coated potassium chloride were mixed in parts by weight to obtain the special function for garlic crops. Type nitrogen and potassium double control fertilizer.

Embodiment 3

[0055] Soil acidification improvement is a long process. An improvement experiment is designed to verify the effect of the special functional nitrogen and potassium dual-control fertilizer for garlic crops prepared by this method on soil acidification improvement. The specific implementation method is as follows.

[0056] (1) A pot experiment was adopted to plant garlic, and the soil type was acidified loam, and the pH value of the soil was tested to be 5.17.

[0057] (2) Set up 4 treatments, conventional compound fertilizer (T1), conventional compound fertilizer with activated humic acid (T2), conventional compound fertilizer with γ-polyglutamic acid (T3), conventional compound fertilizer with activated humic acid and γ- Polyglutamic acid (T4), the special functional nitrogen and potassium dual-control fertilizer (T5) prepared in Example 2 for garlic crops, wherein the amount of compound fertilizer used is 120kg per mu, and all active humic acid containing active humic acid is...

Abstract

The invention discloses a functional nitrogen and potassium double-control fertilizer special for garlic crops. The fertilizer comprises the following raw materials by weight: 560-600 parts of masterbatch particles, 100-120 parts of resin coated urea with a controlled release period of 2 months, 100-120 parts of resin coated urea with a controlled release period of 4 months and 200-240 parts of resin coated potassium chloride. The master batch particles are prepared from the following raw materials by weight: 100-120 parts of activated humic acid, 100-150 parts of urea, 260-300 parts of monoammonium phosphate, 280-330 parts of potassium sulfate, 80-150 parts of ammonium sulfate, 10-15 parts of zinc sulfate heptahydrate, 15-20 parts of borax and 10-30 parts of gamma-polyglutamic acid. Under the condition of ensuring sufficient nutrition supply, the use amount of the fertilizer is reduced, the damage of the fertilizer to the soil ecological environment is reduced, and meanwhile, the fertilizer has the effects of balancing soil acidity and alkalinity, stimulating crop growth and the like.

Description

technical field [0001] The invention relates to the technical field of controlled-release fertilizers, in particular to a special functional nitrogen-potassium dual-control fertilizer for garlic crops and a preparation method thereof. Background technique [0002] There are many factors that affect garlic, among which fertilizer is one of the important factors. Excessive fertilizer consumption and low fertilizer utilization rate are common problems in the existing concentrated garlic planting areas. Excessive fertilizer input also causes soil ecological environment changes and soil acidification, which seriously hinders the sustainable development of the industry. The use of controlled-release fertilizers can significantly increase the utilization rate of fertilizers, reduce the frequency of top dressing, and save labor and fertilizer costs. [0003] Controlled-release nitrogen fertilizers have a significant effect on promoting the growth and development of garlic, but most...
