Preparation method of special water-retention and fertilizer-retention fertilizer for tea trees

Abstract

The invention discloses a preparation method of special water-retention and fertilizer-retention fertilizer for tea trees. The preparation method comprises steps as follows: cottonseed meal, cow dung, borax, vermiculite powder and water are stirred uniformly, heated for fermentation and subjected to thermal insulation, and a premix is obtained; the premix and a water-retention and fertilizer-retention agent are uniformly mixed, ammonium nitrate, plant ash, triple superphosphate, potash magnesium sulphate fertilizer, ammonium molybdate, EDTA chelated zinc and EDTA chelated manganese are mixed uniformly, the mixture is granulated, and the special water-retention and fertilizer-retention fertilizer for the tea trees is obtained. Chemical fertilizer and organic fertilizer are combined, the fertility is sufficient, the fertilizer contains rich nutritional elements essential to growth of tea, improves the tea quality, can be slowly released in soil, can meet requirements of the tea for nutrients at different growth stages, has an extremely remarkable water-retention and fertilizer-retention effect and can optimize the ecological environment of the whole tea planting area; besides, tea is more fragrant and mellow and has brighter and emerald green color and very attractive tea liquor 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 water- and fertilizer-retaining tea trees. Background technique [0002] In our country, tea trees are generally planted on hillsides and hills, because on hills and hills, there are more sunshine, abundant rainfall, more clouds and fog, high air humidity, and strong diffuse light, which is beneficial to the growth of tea trees, but there are also the following problems: In summer and autumn in southern my country, continuous strong light radiation is often accompanied by continuous high temperature weather, which causes serious loss of soil nutrients and water, which is not conducive to the synthesis of nutrients in tea, reduces the aroma of tea, increases the bitter taste of tea, and causes tea Quality declines, how to prepare a kind of water-retaining and fertilizer-retaining ability is strong, the tea tree special ferti...
