Embodiment 1

[0018] The special compound fertilizer for tea is made of the following raw materials by weight ratio: Camellia oleifera cake 50, peanut bran 27, traditional Chinese medicine residue 25, humic acid 33, livestock and poultry manure 28, biological bacteria preparation 4, nitrogen, phosphorus and potassium fertilizer 5, biological insecticide Agent 2, Zinc Sulfate 2, Magnesium Sulfate 2, Sodium Molybdate 1.5, Superphosphate 3. The biological bacteria preparation is an enzyme fungus. The biopesticide is made of the following raw materials in parts by weight: 8 tobacco scraps, 8 garlic stalks, 12 bitter bark vines, 6 soil wattles, 6 diphtheria chrysanthemums, and 10 centipedes. Add water to decoct, collect the filtrate and concentrate it into dry powder production.

[0019] The ratio of NPK in the compound fertilizer is 20:7:5.

[0020] The preparation method of special compound fertilizer for tea is characterized in that it comprises the following steps:

[0021] (...

Embodiment 2

[0026] In order to verify the effect of the present invention, the inventor carried out the following comparative tests in the tea garden of Jinzhai County, Anhui Province in 2011:

[0027] 1. Materials and methods

[0028] (1) Test materials: select tea trees with a tree age of 10 years and similar growth

[0029] (2) Experimental fertilizer: divided into two groups, the first group used diammonium phosphate, urea, potassium sulfate compound fertilizer; the second group used the fertilizer of the present invention.

[0030] (3) Experimental design: Set up two groups of comparative experimental treatments, the area of ​​the plot is 200m 2 , randomly arranged, and repeated 5 times.

[0031] The dosage of the first group of fertilizers: apply 12 kg of diammonium phosphate, 18 kg of urea, and 9 kg of potassium sulfate per mu of tea garden.

[0032] The second group of fertilizer consumption: 40 kg of fertilizer of the present invention is applied per mu of tea garden.

Abstract

The invention discloses a special composite fertilizer for tea. The composite fertilizer is prepared from the following components according to a certain weight ratio: an oil tea cake, peanut bran, Chinese herbal medicine residue, humic acid, manure of livestock and poultry, a biological bacterial preparation, a nitrogen-phosphorus-potassium fertilizer, a biological insecticide, zinc sulfate, magnesium sulfate, sodium molybdate and calcium superphosphate. According to the invention, an organic fertilizer, medium trace elements and a quick-acting inorganic fertilizer are organically combined, the Chinese herbal medicine residue is added at the same time, and therefore, the characteristic of combined fertilizer effects and insecticide effects of the composite fertilizer is obtained. The special composite fertilizer provided by the invention has the advantages of a reasonable formula, balanced nutrition, safety, no pollution, capacity of completely satisfying short-term and long-term demands of tea trees for nutrients and effects of balanced fertilization, soil improvement, environmental protection and effective promotion of output and quality of tea.

Description

technical field [0001] The invention relates to a special compound fertilizer for tea and belongs to the technical field of agricultural fertilizers. Background technique [0002] There are many types of fertilizers currently used for tea tree planting, among which the special fertilizer for tea is mostly NPK compound fertilizer available on the market, which is mainly composed of three inorganic elements N, P, and K, which can meet the growth needs of tea trees in a short time. However, long-term use will damage the soil aggregate structure, which will easily cause soil compaction and soil hardening, thereby affecting the growth of tea trees, and the promotion effect on the growth of tea trees is not obvious. [0003] At the same time, although simple organic fertilizers are rich in organic matter, the release of nutrients is slow, the absorption of tea trees is slow, the fertilizer efficiency is low, and effective balance cannot be reached between various effective nutrien...
