Description

Technical Field

[0001] The invention belongs to the field of tea planting, and in particular relates to a method for increasing tea yield by spraying a carbon source. Background Art

[0002] Tea leaves, commonly known as tea, generally include the leaves and buds of the tea tree. After modern scientific separation and identification, tea leaves contain more than 450 kinds of organic chemical components and more than 40 kinds of inorganic mineral elements, and have high health value.

[0003] However, the output of tea leaves at this stage still needs to be improved, so the technical solution of the present invention is proposed based on this. Summary of the invention

[0004] In order to solve the problems existing in the prior art, the present invention provides a method for increasing tea yield by spraying a carbon source, the method for increasing tea yield comprising the following steps:

[0005] (1) Building a tea garden;

[0006] (2) Compounding the polypeptide macroelement water-soluble fertilizer with a carbon source to obtain a composite spray fertilizer;

[0007] (3) The composite sprayable fertilizer is diluted and then sprayed.

[0008] Preferably, in step (1), the location of the tea garden is 106°10′ east longitude and 26°33′ north latitude. The tea garden built in the present invention is located in Daxiqiao Town, Xixiu District, Anshun City, with longitude and latitude of 106°10′49″ east longitude and 26°33′93″ north latitude. From the perspective of the climate characteristics and sunshine hours of the tea garden, the annual sunshine hours are 1013.3 hours, which is a well-known low-light area. It is more difficult and insufficient for tea leaves to synthesize carbohydrates. In addition, the soil is yellow soil, which makes it more difficult for tea trees to absorb nutrients or due to less water. The present invention is also based on this climate and soil characteristics for subsequent research.

[0009] Preferably, in step (2), the polypeptide macro-element water-soluble fertilizer includes nitrogen fertilizer, phosphorus fertilizer and potassium fertilizer.

[0010] Preferably, the phosphate fertilizer is phosphorus pentoxide, and the potash fertilizer is potassium oxide.

[0011] Preferably, in step (2), the carbon source is brown sugar.

[0012] Preferably, in step (2), the weight ratio of the polypeptide macronutrient water-soluble fertilizer to the carbon source is 480 to 500: 1. The inventors have repeatedly verified that when compounded according to this weight ratio, the composite spray fertilizer can mutually promote the absorption of nutrients by the tea leaves, enhance the resistance of tea leaves to pests and diseases, supplement the carbon source of tea leaves, and accelerate the absorption of soil nutrients and thus accelerate the growth of tea leaves.

[0013] Preferably, in step (2), the concentration of the polypeptide macro-element water-soluble fertilizer is 400-420 g / L.

[0014] Preferably, in step (3), the dilution is 125 to 150 times. The inventors have repeatedly verified that when the dilution multiple is too large, the tea leaves do not grow obviously and the effect is slightly poor; when the dilution multiple is too small, there will be precipitation and insolubility, which is not conducive to spraying and also affects the fluidity and absorption of the solution. By comparison, dilution within the above ratio range is most appropriate.

[0015] The tea yield increasing method of the present invention has the following beneficial effects:

[0016] (i) Increase the various nutrients (trace elements) required for the growth of tea gardens;

[0017] (ii) supplement and increase the deficiency of carbon source synthesized by tea plants;

[0018] (iii) Enhance photosynthesis of tea plants and increase their absorption of soil nutrients;

[0019] (iv) shorten the tea growth period by 6 to 8 days and increase the frequency of picking;

[0020] (v) It increases the tenderness of tea leaves and the tea yield (tea strip yield) of processed products, reduces the amount of broken tea leaves, and prolongs the tea picking period by 5 to 7 days;

[0021] (vi) Effectively improved tea garden yield and tea quality;

[0022] (vii) The leaves of the sprayed tea plantations are bright green and will not show any signs of fertilizer or nutrient deficiency. DETAILED DESCRIPTION
