Substrate Culture,A Kind Of New Soilless Culture

AUTHOR： DATE：2019/8/8 10:07:26 VISITS：

Substrate culture is one of the most popular methods in soilless culture. It fixes the roots of crops in organic or inorganic substrates and supplies nutrient solution to crops by drip irrigation or fine-flow irrigation. The cultivation medium can be packed in plastic bags or laid in cultivation ditches or troughs. The nutrient solution of matrix culture is non-circulating, which is called open-circuit system. This can avoid the spread of diseases through the circulation of nutrient solution.

Substrate culture has strong buffer capacity, no contradiction between water, nutrients and oxygen supply, and the equipment is simpler than hydroponic culture and aerosol culture, and even does not need power, so it has less investment and low cost, and is widely used in production. Based on the current situation of our country, substrate cultivation is the most practical way.

There are many substrates for soilless cultivation, such as garden defoliation, withered branches, straw, sawdust, bark, particles and other industrial and agricultural wastes and scraps, which can be cut or crushed to the appropriate size according to their own technological requirements. Then ferment it with the fermentation assistant of Jinbao matrix soil. The fermentation method is as follows:

1. Nutrition solution.

2. Material stacking.

3. Spraying inoculation.

4. Overturn the cover.

5. Fermentation is completed.
