【Application】：

1. With strong water holding capacity, it will form a film on the surface of root hairs, which has the function of protecting root hairs. It is also the best transportation platform for close contact between nutrients, water and root hairs in the soil, and can effectively improve the dissolution, storage, transportation and absorption of fertilizers. Prevent sulfate, phosphate, oxalate from precipitation with metal elements, so that crops can more effectively absorb phosphorus, calcium, magnesium and trace elements in the soil. Promote the development of crop roots and strengthen disease resistance.

2. It has excellent buffer capacity for acid and alkali, can effectively balance soil pH value, and avoid acid soil quality caused by long-term use of chemical fertilizers.

3. The combined precipitation of toxic heavy metals has excellent chelating effect on Pb+2, Cu+2, Cd+2, Cr+3, Al+3, As+4 and other toxic heavy metals.

4. Enhance plant disease resistance and stress resistance, integrate plant nutrition and water active ingredients in soil, and enhance resistance to symptoms caused by plant pathogens transmitted by soil.

5. Promoting production increase can increase the output of tea, fruits, vegetables and other agricultural products rapidly by 10-20%.
