The contents of crude protein, crude fat, crude fiber, nitrogen-free extract, crude ash and moisture in rice hull were all superior to those of rice straw. As long as a certain amount of supplementary material was added, the biological efficiency could reach more than 100%. Rice husk treatment: Add 2 kg of lime per 100 kg of water.

At the last turning, the enemy was sprayed with dichlorvos to kill the pests. Cultivation method: It can be cultivated in plastic bags, and can also be cultivated in a pit-type trampoline.
