Cultivation techniques of gramineous insects

Gramineae is a kind of annelid family Bombyx mori, which usually lives in coastal or estuarine shoals. It is mainly found in Zhejiang, Guangdong and Fujian provinces in China. It is a delicious food and can be used as traditional Chinese medicine. It has the effect of reducing swelling and benefiting qi. The breeding methods of grass insects are introduced as follows.

Selection and Design of Seedling Farm

The seedling farm is divided into two parts: the awning and the breeding farm. The top of the awning is built with shading net material and thin film, covering the culture trough, and a culture trough is arranged in the awning.

Selection of mud and water

The mud is selected from the surface mud of the river, and the mud needs to be filtered first, and the mud is laid flat in the culture tank, and then the culture tank is discharged, at the same time, the salinity of the water is adjusted to 18 degrees, and the acidity and alkalinity is 5-8 degrees.

Pre-fertilization preparation

The filtered water is poured into the plastic box, and an oxygen pump is placed in each box for oxygenation.

Selection of species

Choose healthy, full-bodied, brightly colored, injury-free males and females as species.

Fertilization

Put the seed worms into a plastic box already filled with water to fertilize them naturally, and when they are artificially inseminated, when the fertilized eggs become "8"-shaped fertilized eggs and then into four swimming globular fertilized eggs and rotate on their own, water gauze is used to wash them.

Stocking

Put the swimming spherical fertilized eggs after washing into the culture tank, the method is to pour the swimming spherical fertilized eggs in the box into the culture tank after each box is washed, and desalinate the salinity of the water in the culture tank after four swimming eggs become pupae and then develop into three-node worms.

Feeding

When the larvae develop into three-node worms, they are fed on the first day of desalination. When the larval holes appear in the soil, the water in the culture trough is released, and then the food is sprinkled on the surface of the mud to feed. Then the filtered water is put into the culture tank the next morning, and the silkworm is fed continuously for 20 days. After the cultivation of the wart silkworm is completed, it is released into the rice field for harvest.
