Problems solved by technology

However, due to the one-sided pursuit of production by tea farmers, large amounts of chemical fertilizers were used, resulting in a decline in the quality of green tea and aggravation of pests and diseases. They were then forced to spray pesticides, resulting in excessive pesticide residues in tea leaves and causing tea safety problems.

Embodiment 1

[0018]When used as topdressing, the fertilizer a) is divided into two uses. The first topdressing is implemented before the tea tree sprouts in early spring. Rotary tillage. If the water-soluble fertilizer method is adopted, the fertilizer concentrate can be directly applied to the roots of the tea tree by the method of flow application. The second topdressing is carried out in September-October, and the amount of topdressing is 15kg / mu. The amount of fertilization should be properly adjusted according to the age of the tree and the fertility of the soil. For example, the amount of fertilization for large tea trees or alkaline soil should be increased by about 10%. The total amount of fertilizer used is 30kg / mu. If the root of the tree is covered with organic matter such as tea tree branches and leaves or weeds to improve the soil every year, the effect of this balanced nutrient fertilizer will be better.

[0019] Specific method of topdressing: You can manually spread the ...

Embodiment 2

[0021] When used as topdressing, the fertilizer a) is divided into two times for use. The first topdressing is implemented before the budding of tea trees in early spring, and the fertilization rate is 20kg / mu. The balanced nutrient fertilizer can be evenly spread on the roots of tea trees manually, and mechanically Rotary tillage. If the water-soluble fertilizer method is adopted, the fertilizer concentrate can be directly applied to the roots of the tea tree by the method of flow application. The second topdressing is carried out in September-October, and the amount of topdressing is 15kg / mu. The amount of fertilization should be properly adjusted according to the age of the tree and the fertility of the soil. For example, the amount of fertilization for large tea trees or alkaline soil should be increased by about 10%. The total amount of fertilizer used is 35kg / mu. If the root of the tree is covered with organic matter such as tea tree branches and leaves or weeds to imp...

The amount of fertilization should be properly adjusted according to the age of the tree and the fertility of the soil. For example, the amount of fertilization for large tea trees or alkaline soil should be increased by about 10%. The total amount of fertilizer used is 40kg / mu. If the root of the tree is covered with organic matter such as tea tree branches and leaves or weeds to imp...

Abstract

The invention discloses balanced nutrition fertilizer for cultivation of green tea. The balanced nutrition fertilizer is prepared from the following components of KNO3, KCl or K2SO4, KH2PO4, (NH4)H2PO4 or Ca(H2PO4)2.H2O, MgSO4.7H2O or MgSO4.H2O, (NH4)2SO4, Ca(NO3)2.4H2O or 5Ca(NO3)2NH1NO3.10H2O, FeSO4.7H2O, EDTA-Na, MnSO4.H2O (manganese sulfate monohydrate), ZnSO4.7H2O (zinc sulfate heptahydrate),and H3BO3 (boric acid). Proved by experiment results, compared with the existing conventional fertilizer applying methods (organic fertilizer, composite fertilizer, urea, potassium chloride, potassium sulfate, trace element fertilizer and the like for rapeseed meal and the like) by peasants on the basis of output per mu, the balanced nutrition fertilizer has the advantages that the usage method is simple and convenient; the applying amount of the fertilizer is small, the plant can grow strongly, the pest and disease-resistant property is realized, the cost of labor is reduced, and the outputper mu is increased by 2 to 10%; the quality, mouth feel and aroma of tea are improved; the original flavors of different varieties of green tea are restored, and the storage-resistant property of thetea is improved.

Description

technical field [0001] The invention relates to the technical field of tea production, in particular to a green tea balanced nutrient fertilizer used for green tea cultivation. Background technique [0002] China is the country with the longest history of using tea trees. According to legend, "Shen Nong tasted all kinds of herbs, encountered 72 poisons every day, and got rid of them with tea." Originated from Shennong". According to historical records, during the period of King Wu of Zhou, people in the southwest region paid tribute to the Zhou Dynasty with tea as a tribute. It has been 3,000 years ago. At present, there are many wild tea trees around 2000 years old in the Yunnan area of ​​my country, and they are widely distributed, which also proves that China is the origin of tea trees. In my country, drinking green tea has the longest history, the most extensive production area, the most abundant variety, and the largest output. It is the largest tea category in China....
