Description

Technical Field

[0001] The invention relates to the technical field of tea tree planting, and in particular to a tea garden annual management method that effectively prevents and controls the occurrence of tea cake disease. Background Art

[0002] Tea cake disease is a disease caused by the Basidiomycetes fungus, which occurs on tea trees. The disease mainly occurs on young leaves and stems. The diseased leaves initially develop light yellow water-soaked spots, which are round and sunken, with corresponding protrusions on the back in the shape of steamed buns. There is white powdery mildew on the surface, which later turns dark brown, and the leaves become deformed and twisted. The buds and branches are affected, swollen and tumor-like, and produce grayish-white powder.

[0003] Tea cake disease occurs in tea gardens in all regions, with an incidence rate of 20-30% in general tea gardens and 60-80% in severe tea gardens. The young tissues of the entire tea garden are covered with white cellular spots, seriously affecting the yield. Tea made from diseased leaves tastes bitter and turbid, with mixed leaves and many fragments. Indicators such as tea polyphenols and the total amount of amino acids in the water extract are all reduced.

[0004] The pathogen overwinters in the diseased leaves as mycelium. In the following spring or autumn, the mycelium germinates and forms new lesions. Under humid conditions, with an average temperature of 5 to 20°C and a relative humidity higher than 80%, a white powdery substance, i.e., the hymenium composed of basidiospores, forms on the surface of the lesions, becoming the primary source of infection. After the basidiospores mature, they spread with wind and rain, invading the young leaves of new shoots, and new lesions appear. Therefore, if tea cake disease is not prevented and controlled in time, it will occur every year and become a common disease in tea gardens, which will have a significant impact on the yield and quality of tea leaves.

[0005] Therefore, how to provide a tea garden annual management method that effectively prevents and controls the occurrence of tea cake disease to solve the technical problem that tea cake disease of tea trees occurs frequently and has poor prevention and control effects is an issue that technical personnel in this field urgently need to solve. Summary of the invention

[0006] The purpose of the present invention is to provide a tea garden annual management method for effectively preventing and controlling the occurrence of tea cake disease.

[0007] In order to achieve the above-mentioned object of the invention, the present invention provides the following technical solutions:

[0008] The present invention provides a tea garden annual management method for effectively preventing and controlling tea cake disease, which comprises spraying a composite probiotic agent in March, May and July respectively; applying a base fertilizer in November;

[0009] The composite probiotic comprises the following components in parts by weight: 1-2 parts of Bacillus subtilis, 0.4-0.6 parts of Bacillus cereus, 0.4-0.6 parts of Bacillus amyloliquefaciens, 0.5-0.7 parts of Bacillus velez, 0.3-0.7 parts of Pseudomonas aeruginosa, 0.4-0.8 parts of Pseudomonas aeruginosa, 10-16 parts of 2,6-dichloroisonicotinic acid, 20-30 parts of potassium humate, 6-10 parts of polyglutamic acid, 2-4 parts of dispersant and 1-2 parts of emulsifier.

[0012] Preferably, the bacterial concentrations of Bacillus subtilis, Bacillus cereus, Bacillus amyloliquefaciens, Bacillus velezensii, Pseudomonas aeruginosa are all 500 million to 700 million per gram.

[0013] Preferably, the base fertilizer includes the following components in parts by mass: 20-30 parts of earthworm manure, 90-110 parts of cow dung, 5-7 parts of compound fertilizer, 20-30 parts of mushroom residue, and 6-10 parts of bean cake.

[0014] Preferably, the preparation method of the base fertilizer is: mixing compound enzyme, earthworm castings and water for enzymolysis to obtain material 1; and mixing material 1, cow dung, compound fertilizer, mushroom residue and bean cake for composting to obtain base fertilizer.

[0015] Preferably, the complex enzyme includes papain, ligninase, cellulase, amylase and peptidase in a mass ratio of 3-7:6-10:4-8:5-9:3-7; the enzymatic hydrolysis time is 2-4h; and the enzymatic hydrolysis temperature is 30-40°C.

[0016] Preferably, the ratio of N, P and K in the compound fertilizer is 10:1.5-2.5:3-5.

[0017] Preferably, the composting time is 7 to 9 days.

[0018] Preferably, the application amount of the base fertilizer is 1500-2000 kg / mu.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The composite probiotic used in the present invention has the dual effects of promoting growth and preventing and treating tea cake disease. Bacillus subtilis, Bacillus cereus, Bacillus amyloliquefaciens and Bacillus velez in the composite probiotic have antagonism to pathogenic bacteria, and have the characteristics of fast reproduction speed and large spore production, so it has excellent prevention and treatment effect on tea cake disease. Pseudomonas aeruginosa and Pseudomonas aeruginosa chitinase-producing bacteria, chitin is an antibacterial protein, has inhibitory activity on fungal spore germination and mycelial growth, and the addition of the two components has a good prevention and treatment effect on exobasidiomycetes.

[0021] Sodium lignin sulfonate has a certain viscosity and adsorption capacity, and has strong dispersibility. Polyglutamic acid has the function of absorbing water, retaining moisture and regulating plant growth. The two components are used together as components of a composite probiotic agent, which can make the agent adhere better to the tea leaves and form a protective film, thereby prolonging the effect and duration of the agent.

[0022] The 2,6-dichloroisonicotinic acid added to the compound probiotic is a plant immune inducer that can enhance plant disease resistance, activate plant systemic acquired resistance response, and provide broad-spectrum disease resistance. Potassium humate is a foliar fertilizer component that can enhance crop photosynthesis, increase crop yield and quality, promote crop absorption of nutrients, and improve crop stress resistance.

[0023] In the base fertilizer prepared by the present invention, the native earthworm castings also contain many unused biological macromolecules and other nutrients, such as undigested substrates, crude protein and the like. The present invention mixes the earthworm castings with a composite enzyme preparation, decomposes the macromolecular nutrients through enzymatic hydrolysis, and enables them to be added and used as raw material components of fertilizers, which has an excellent promoting effect on the growth of tea trees, helps to enhance the tree vigor, and improves the stress resistance of tea trees.

[0024] The annual management method for tea gardens provided by the present invention has a significant growth-promoting effect on tea trees. Compared with other control groups, the color of the young leaves is more tender green, the buds are more neat, and the length of the young leaves and the number of buds are significantly improved. The method has a significant control effect on tea cake disease and is significantly better than the existing drugs. DETAILED DESCRIPTION

[0060] Experimental Example 1

[0061] A tea garden in Qingyuan City, Guangdong Province was selected for planting experiments. The tea tree variety was Qingyuan green tea, 8 years old. After the experimental land was evenly divided, each experimental group randomly treated three areas.

[0062] Among them, the method of Example 3 was used as the experimental group;

[0063] In control group 1, other methods were the same as those in Example 3, except that the earthworm manure in the base fertilizer was not subjected to enzymatic hydrolysis.

[0064] Control group 2: other methods were the same as those in Example 3, except that the papain and peptidase in the complex enzyme were replaced with an equal amount of distilled water.

[0065] Control group 3, other methods are the same as Example 3, the only difference is that the composite probiotic agent is replaced by Aipuda photodynamic tea special ecological light carbon nutrition conditioner (used according to the instructions); Pest control: during the peak period of pests, spray 70% methyl thiophanate wettable powder 1000 times solution, spray 3 times, each time at an interval of 7d, spray until the leaf surface just drips water.

[0066] Control group 4: other methods were the same as those in Example 3, except that Pseudomonas aeruginosa and Pseudomonas aeruginosa were replaced by equal amounts of Bacillus megaterium and Trichoderma.

[0067] Control group 5, other methods are the same as Example 3, the only difference is that the base fertilizer is replaced by: 1800 kg of livestock manure, 130 kg of rapeseed cake, 15 kg of urea, 30 kg of superphosphate, and 20 kg of potassium sulfate per mu.

[0068] The water control group was composed of the experimental group in which the compound probiotic agent was replaced with an equal amount of water, and the basal fertilizer was replaced with the same basal fertilizer as the control group 5.

[0069] After two years of implementation, different experimental groups were randomly sampled at five points 10 days after the third application of pesticides in May of the third year (end of May). 2 The number of buds, bud length, and fresh weight of 100 buds of tea trees were investigated and the average values ​​were taken.

[0070] Ten days after the third application of pesticides (end of May), the occurrence of tea cake disease on tea trees was investigated. Referring to GB / T17980.82-2004 standard, each experimental group randomly selected the third leaf below the bud of the new shoot, randomly investigated the disease grade of 100 leaves, and calculated the prevention effect of each treatment. The grading standard and calculation formula are shown in Table 1, and the investigation results are shown in Table 3.

[0071] Table 1 Classification standards

[0072]

[0073]

[0074] Disease index (%) = 100 × ∑ (number of diseased leaves at each level × corresponding disease level) / (total number of plants surveyed × 9 highest level representative values)

[0075] Control effect (%) = [(disease index of the clean water control area - disease index of the drug-treated area) / disease index of the clean water control area] × 100%.

[0080] From the data obtained in Table 2 and Table 3, it can be seen that the fertilization method provided by the present invention has a significant growth-promoting effect on tea trees. Compared with other control groups, the color of its young leaves is more tender green, the buds are more neat, and the length of young leaves and the number of buds are significantly improved. The management method also has a significant preventive and therapeutic effect on tea cake disease, and its preventive and therapeutic effect is significantly better than the drugs in the prior art.

[0081] From the data of control groups 1 and 2, it can be seen that for native earthworm castings, a suitable treatment method is required to maximize their effectiveness. If enzymatic hydrolysis is not performed or different types of enzymes are used, the fertilizer efficiency of the fertilizer will be significantly affected, which is caused by the inadequate decomposition and release of the nutrients in the native earthworm castings. From the data of control group 5, it can be seen that if the base fertilizer provided by the present invention is replaced with other types of base fertilizers, it will have a significant impact on the growth of tea trees.

[0082] It can be seen from the data of control groups 3 and 4 that the composite probiotic agent provided by the present invention has the dual effects of promoting the growth of tea trees and preventing tea cake disease. If some of the strains are replaced with other types of strains, it will have a significant impact on the efficacy of the agent.

[0083] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
