Problems solved by technology

Crop growth needs 18 kinds of essential nutrients, therefore, the nutrients contained in conventional fertilizers cannot fully meet the needs of crops
At present, in my country's agricultural production, it is common for crops to lack zinc. Zinc mainly promotes cell division and reproductive growth. Lack of zinc will lead to short plants, small leaf disease, and stunted growth.
Zinc deficiency will seriously affect crop yield
[0003] At present, the compound fertilizer system mainly produces nitrogen, phosphorus and potassium three-element compound fertilizers, and the production technology is lacking in the efficient and slow-release addition of organic matter, resulting in low efficiency and utilization of compound fertilizers; and humic acid compound fertilizers, because they can increase crop yields , Improve the quality of agricultural products, improve the soil and other aspects have good effects, can increase the utilization rate of organic matter, enhance crop resistance to disease, early dryness, cold resistance, and salt-alkali resistance. It has gradually been recognized and accepted by farmers and has become a fertilizer family. an important species
However, the soil improvement effect and biological effect of the compound fertilizer produced by unactivated humic acid are not obvious

Embodiment 1

[0025] (1) A kind of compound fertilizer is formed by the proportioning of following components by weight:

[0026] 20% sugarcane bagasse, 5% ammonium humate, 8% ammonium dihydrogen phosphate, 10% modified zeolite, 5% mixture of prickly prickly ash powder and tea cake powder by weight 1:1, poly 5% vinyl alcohol, 5% surfactant Span-80, 5% mixture of zinc sulfate and potassium chloride with a mass ratio of 1:1, and the balance is activated carbon powder;

[0027] The modified zeolite is prepared by the following method: grind the zeolite into a 150-mesh powder, use a naphthalene acetic acid ethanol solution with a weight three times that of the zeolite, and a concentration of 30%, soak it at 50°C for 6 hours, and then add a solution with a weight three times the weight of the zeolite. , 30% triethylamine ethanol solution for neutralization; drying the product to obtain the modified zeolite.

[0028] (2) Preparation method:

[0029] 1) Mix sugarcane sugar residue, ammonium huma...

Embodiment 2

[0033] (1) A kind of compound fertilizer is formed by the proportioning of following components by weight:

[0034] Sugarcane bagasse 40%, ammonium humate 8%, ammonium dihydrogen phosphate 5%, modified zeolite 15%, prickly prickly ash powder, tea seed cake powder, Anhui berberry powder 5% by weight 1:1:1 mixture , the concentration is 98% polyvinyl alcohol 5%, surfactant Span-805%, zinc sulfate and potassium chloride mass ratio are 1:1 mixture 5%, and the balance is activated carbon powder;

[0035] The modified zeolite is prepared by the following method: grind the zeolite into a 150-mesh powder, use an ethanol solution of indolebutyric acid whose weight is 3 times that of the zeolite, and whose concentration is 30%, soak it at 50°C for 6 hours, and then add the zeolite 3 times the weight and 30% ethanol solution of triethylamine for neutralization; drying the product to obtain the modified zeolite.

[0036] (2) Preparation method:

[0037] 1) Mix sugarcane sugar residue, a...

Embodiment 4

[0048] The organic fertilizer of embodiment 1-2 and comparative ratio is carried out comparative test, sets up following several groups altogether (all fertilizers are divided into four application, each interval is one month, and test result is obtained when crops are harvested):

[0049] Group A1: use the organic fertilizer prepared in Example 1 as the cotton base fertilizer, and the usage rate is 50kg / mu;

[0050]A2 group: use the organic fertilizer prepared by embodiment 2 to use as cotton base fertilizer, use amount 50kg / mu;

[0051] Group B: use the organic fertilizer prepared by comparative example to use as cotton base fertilizer, and the usage rate is 50kg / mu;

[0052] Group C: No organic fertilizer was used.

[0053] 1) Fertilizer effect comparison test:

Abstract

The invention discloses compound fertilizer. The compound fertilizer comprises candy pomace, ammonium humate, ammonium dihydrogen phosphate, modified zeolite, a traditional Chinese medicine additive,an absorption promoter, a surfactant, a microelement additive and charcoal active powder. The invention further discloses a preparation method of the compound fertilizer. The compound fertilizer can effectively reduce the occurrence rate of crop diseases and pests, improve the yield and quality of crops, improve soil, evenly release nutrient, and increase the contents of organic matters, nitrogen,phosphorus and potassium and various microelements, has the advantages of high fertilizer efficiency, fast absorption, safety and environment protection, and does not have residue.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to a compound fertilizer and a preparation method thereof. Background technique [0002] The main nutrients in compound fertilizers are nitrogen, phosphorus and potassium. Crop growth needs 18 kinds of essential nutrients, therefore, the nutrients contained in conventional fertilizers cannot fully meet the needs of crops. At present, in my country's agricultural production, it is common for crops to lack zinc. Zinc mainly promotes cell division and reproductive growth. Lack of zinc will lead to short plants, small leaf disease, and stunted growth. The lack of zinc will have a serious impact on crop yield. [0003] At present, the compound fertilizer system mainly produces nitrogen, phosphorus and potassium three-element compound fertilizers, and the production technology is lacking in the efficient and slow-release addition of organic matter, resulting in low effi...
