How to build the breeding room and pond of Tuyuan?

It is necessary to create a good and comfortable living environment for Tu Yuan. Suitable sites and equipment can make Tu Yuan grow rapidly and increase output. At present, there are mainly two kinds of breeding rooms for breeding Tuyuan: general breeding rooms and shed-type breeding rooms.

1. The general breeding room should choose high terrain, damp, convenient drainage, back water to the sun, relatively quiet places to build, houses sitting north and south, front and rear windows, so that indoor air can convection when needed, doors and windows are equipped with screen netting to prevent male soil adults from flying and native enemies invading. The room temperature does not exceed 36 ℃. Some deciduous trees can be planted in front and behind the house, which can provide shade in summer and do not hinder the light in winter. Electric lights are installed in the feeding room, which can not only adjust the lighting time as needed, but also illuminate when feeding in the evening. 4-5-story aquaculture ponds can be built on both sides of the room.

2. The large shed-type breeding house should choose a place with flat ground and plenty of sunshine to build a slope-type plastic solar greenhouse. The north wall is 2.5 meters high, the front wall is 1.5 meters high, and the shed is 4 meters 5 meters wide. The shed wall can be rammed with soil or with red brick, the floor inside the shed can be smoothed with cement, and the top film should be covered with double-layer polyvinyl chloride film to improve the temperature of the shed and prolong the service life of the film. Fix the film with a pressing line and install a small door on one wall and a window on the other.

The breeding pond in the greenhouse can be built as a single-layer or multi-layer pond, which is made of bricks into several small pools with a height of 30 centimeters, and the inner wall of the pool is affixed with ceramic tiles or glass strips to prevent soil elements from escaping. The pool can be built in two rows, left and right, with an aisle in the middle. The single-layer pool is easy to manage and operate, but the utilization rate of the greenhouse is not high.

A multi-layer pool is a multi-layer bracket made of triangular iron or wood strips, on which plastic pots are placed. The distance between layers is 30 cm, which is divided into front, middle and back rows, with aisles left in the middle. This multi-layer pot culture method has the advantages of convenient management and uniform heating, which can increase the feeding quantity, increase the yield and have high economic benefits.
