Problems solved by technology

However, long-term use will damage the soil aggregate structure, which will easily cause soil compaction and hardening of the soil, thus affecting the growth of tea trees.
[0003] At the same time, although pure organic fertilizer is rich in organic matter, the absorption of tea trees is slow, the fertilizer efficiency is low, and the balance of various effective nutrients cannot be achieved.

Embodiment 2

[0011] Example 2. The special compound fertilizer for tea has the following components and weight ratio: 15% urea, 30% superphosphate, 1% potassium sulfate, 30% calcium sulfate, 5% aluminum sulfate, 10% humic acid and 20% furfural slag. The preparation method is the same as in Example 1.

Embodiment 3

[0012] Example 3. The special compound fertilizer for tea has the following components and weight ratio: 30 urea, 5 superphosphate, 4 potassium sulfate, 10 calcium sulfate, 3 aluminum oxide, 30 humic acid and 10 furfural slag. The preparation method is the same as in Example 1.

[0013] In the present invention, the weight percentage of nitrogen can reach 10-30%, the weight percentage of phosphorus can reach 5-30%, the weight percentage of potassium can reach 3-10%, and the weight percentage of calcium can reach 20-50%. The weight percentage can reach 1-15%, the weight percentage of humic acid can reach 10-30%, and the weight percentage of furfural slag can reach 10-40%.

[0014] The medium and trace elements calcium and aluminum in the present invention can prevent and treat various physiological diseases caused by the lack of medium and trace elements during growth in addition to being used for tea trees to absorb minerals after application.

Abstract

The invention relates to a composite fertilizer for tea trees, which is prepared from urea, superphosphate, potassium sulfate, calcium sulfate, aluminum hydroxide, humic acid and furfural slag by a predetermined proportion.

Description

technical field [0001] The invention belongs to the field of fertilizers, in particular to special organic and inorganic compound fertilizers for tea. Background technique [0002] There are many types of fertilizers at present, among which special fertilizers for tea are mostly composed of the three major elements of N, P, and K in inorganic fertilizers, which can meet the growth needs of tea trees in a short time. However, long-term use will damage the soil aggregate structure, which will easily cause soil compaction and hardening of the soil, thus affecting the growth of tea trees. [0003] At the same time, although simple organic fertilizers are rich in organic matter, the absorption of tea trees is slow, the fertilizer efficiency is low, and the balance of various effective nutrients cannot be reached. Contents of the invention [0004] The object of the present invention is to provide a special compound fertilizer for tea which organically combines organic substanc...
