1、 Mushroom soil

The nutrient content of Lentinus edodes soil is moderate and slightly acidic. It has the advantages of long fertilizer effect period, strong water permeability and permeability, and good ability of water and fertilizer retention. The orchids cultivated with it have thick leaves, developed roots and bright dark green leaves. More experiments show that if only it is planted, the widening and thickening of orchid leaves is more obvious, especially Jianlan

2、 Grain carbon shell

The grain carbon shell is alkaline when fresh and becomes neutral after exposure to the sun and rain for about 1 month. At this time, it can be used to plant orchids. It mainly contains potassium. Adding the mixture can loosen the soil, facilitate drainage and improve the soil temperature

3、 Bone charcoal

Bone char is rich in scales. It has the advantages of fast fertilizer effect and long-lasting fertility. Adding proper amount of phosphate fertilizer into the mixture can increase the energy. When cultivating orchids, the following three kinds of fertilizers can be used to widen and thicken the leaves, make the roots grow more vigorous and the flowers bloom larger and more colorful
