Preparation method of special fertilizer capable of improving tea quality for tea trees

Abstract

The invention discloses a preparation method of special fertilizer capable of improving the tea quality for tea trees. The preparation method comprises the following steps: firstly, uniformly mixing soybean meal, wormcast, zinc borate, zeolite powder and water, and then raising the temperature and keeping the temperature to obtain a first material; secondly, adding water, Tween 80 and dispropriated rosin into oxidized polyethlene wax, then raising the temperature and stirring; reducing the temperature, and adding hydrated alumina to carry out homogenizing treatment; adding an alginate solution into a mixture, carrying out uniform mixing, and then dropwise adding a calcium nitrate solution in a stirring state, washing with water, drying and calcining to obtain a second material; thirdly, uniformly mixing the first material with the second material, then adding urea, potassium nitrate, monocalcium phosphate, magnesium sulfate, ammonium molybdate, zinc humate and diaminoferric xanthohumate into the mixture, carrying out uniform mixing, and then granulating to obtain the special fertilizer capable of improving the tea quality for the tea tress. The special fertilizer disclosed by the invention has the advantages that the fertility is sufficient and the tea quality is improved; in addition, the fertilizer can be slowly released in the soil, so that the effects of water conservation and fertilizer retention are extremely obvious; besides, the tea has the advantages of better fragrance, mellowness, brighter and bluish green color and attractive tea soup color.

Description

technical field [0001] The invention relates to the technical field of special fertilizers, in particular to a method for preparing special fertilizers for tea trees to improve the quality of tea leaves. Background technique [0002] Tea culture is very important in the life of the Han people. When King Wu defeated Zhou, tea was used as a tribute. In the late period of primitive communes, tea became an item for goods exchange. In the Warring States period, tea had a certain scale. There are records of tea in the pre-Qin "Book of Songs". Another example is that in the Han Dynasty, tea became a special tonic for Buddhist "zazen". During the Wei, Jin, Southern and Northern Dynasties, there was already a trend of drinking tea. In the Sui Dynasty, the whole people generally drank tea. In the Tang Dynasty, the tea industry flourished, and tea became "one cannot live without tea for a day". Teahouses, tea banquets, and tea parties appeared, and guests were encouraged to come ...

Problems solved by technology

[0003] At present, when fertilizing tea trees according to agricultural methods, in order to increase the yield, a large amount of pesticides, plant growth regulators, chemical food additives and other substances are often added, but the quality of the tea leaves thus obtained is difficult to improve and needs to be improved urgently
