Embodiment 1

[0020] Liquid chitosan compound fertilizer formula is: 50g / L, Zn 2+ 200mg / L, Al 3+ 100mg / L, pectin 8g / L, and the rest is water.

[0021] Liquid water-soluble fertilizers are prepared by:

[0022] (1) After 150 parts of corn stalks, 10 parts of animal carcasses and 120 parts of human excrement were harmlessly treated, 5 parts of sodium polyacrylate and 2 parts of citric acid were added, and anaerobic fermentation was carried out in a fermentation tank at room temperature for 23 days. The supernatant was filtered and concentrated to a density of 1.2 to obtain a biomass fermentation broth;

[0023] (2) A mixture of urea, highly soluble potassium fulvic acid, aluminum nitrate, zinc nitrate, and aspergillus glucoside is formed at a mass ratio of 70:15:0.2:0.1:0.005, and 1 part of the mixture is mixed with 30 parts of the biomass fermentation broth After filtering.

Embodiment 2

[0025] The liquid chitosan compound fertilizer formula is: low molecular weight chitosan 30g / L, Zn 2+ 150mg / L, Al 3+ 80mg / L, pectin 8g / L, and the rest is water.

[0026] Liquid water-soluble fertilizers are prepared by:

[0027] (1) After harmless treatment of 100 parts of corn stalks, 20 parts of animal carcasses and 80 parts of human excrement, 3 parts of sodium polyacrylate and 2 parts of citric acid were added, and anaerobic fermentation was carried out in a fermentation tank at room temperature for 20 days. The supernatant was filtered and concentrated to a density of 1.2 to obtain a biomass fermentation broth;

[0028] (2) A mixture of urea, highly soluble potassium fulvic acid, aluminum nitrate, zinc nitrate, and aspergillus glucoside is formed at a mass ratio of 66:20:0.5:0.1:0.005, and 1 part of the mixture is mixed with 25 parts of the biomass fermentation broth After filtering;

Embodiment 3

[0030] Liquid chitosan compound fertilizer formula is: low molecular weight chitosan low molecular weight chitosan 20g / L, Zn 2+ 120mg / L, Al 3 + 150mg / L, pectin 8g / L, the balance is water;

[0031] Liquid water-soluble fertilizers are prepared by:

[0032] (1) After 200 parts of corn stalks, 18 parts of animal carcasses and 150 parts of human excrement were harmlessly treated, 5 parts of sodium polyacrylate and 2 parts of citric acid were added, and anaerobic fermentation was carried out in a fermentation tank at room temperature for 30 days. The supernatant was filtered and concentrated to a density of 1.2 to obtain a biomass fermentation broth;

[0033] (2) A mixture of urea, highly soluble potassium fulvic acid, aluminum nitrate, zinc nitrate, and aspergillus glucoside is formed at a mass ratio of 76:14:0.2:0.1:0.0004, and 1 part of the mixture is mixed with 20 parts of the biomass fermentation broth After filtering.

Abstract

The invention belongs to the technical field of fertilizers, and particularly relates to a special fertilizer for a high-density tea garden and a fertilizing method thereof. The fertilizer is composedof a liquid chitosan compound fertilizer and a liquid water-soluble fertilizer. The fertilizer provided by the invention can promote wound healing of tea tree branches after Taiwan cradling, can promote roots of the tea trees to germinate new branches after Taiwan cradling and can provide the nutritional requirements of high-density planting tea garden production. The fertilizer provided by the invention is scientific in proportioning, has higher water solubility, can be used for supplementing tea tree nutrition through water-fertilizer integrated drip irrigation in a tea garden, and is highin fertilizer utilization rate and small in application amount; the prepared fertilizer has no strong pungent smell, nutrition is supplemented according to the growth requirement characteristics of tea trees, medium trace elements and amino acid required by the tea trees are supplemented, and after the fertilizer provided by the invention is used for a long time, the disease resistance and insectresistance of the tea trees can be improved; tea garden soil can be improved, and the soil micro-ecological environment required by tea tree growth is improved; and tea tree root activity is improved,and tea tree root germination is promoted.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a special fertilizer for high-density tea gardens and a fertilization method thereof. Background technique [0002] The production part of the tea tree is the leaves, which need to be picked many times during the production process of the year. Reasonable use of fertilizers is the basis for high-quality and efficient tea garden production. At present, excessive and unreasonable fertilization in tea gardens has caused soil compaction and environmental pollution in some tea gardens. The use of special fertilizers for tea trees is an important way to reduce chemical fertilizers in tea gardens. Usually, for the cultivation and fertilization of young tea trees in the conventional cultivation mode, the fertilizer is mainly 1:1:1 compound fertilizer with high phosphorus and potassium content, and for the tea gardens in the picking period of the conventional cultivation m...
