What conditions do you need at the mouth of the pond where millet grass breeds crayfish?

Many crayfish farming ponds cultivate crayfish by planting Elodea. Under the influence of many factors, farmers feel that Elodea is difficult to control in many aspects, which makes the water quality difficult to regulate and the crayfish culture process difficult to observe. Also known as the "three difficulties" phenomenon.

In the production practice, some farmers have created the cultivation way of raising crayfish with millet grass. Millet grass is a kind of single plant with fast adaptability, early germination and rapid growth. It can not only simply control its growth density, but also easily observe the living condition of crayfish in crayfish ponds at any time, and improve the recapture rate of crayfish.

So, what conditions do you need at the mouth of the pond where millet grass breeds crayfish?

I. the necessary conditions for crayfish culture in Xiaomi Caotangkou

1. The pond should have sufficient bottom fertilizer or thick silt layer to ensure adequate nutrition for the growth of millet grass. In addition, the bottom of the pond should be as flat as possible to ensure uniform water depth, which is conducive to the germination and growth of millet grass.

2. The drainage and irrigation system should be complete, so that it can drain and irrigate, prevent drought and waterlogging.

3. The depth of the pond should be about 1.5 meters, and the aquaculture pond with a slightly larger area is the best-the deep water pond has a large water capacity and the dissolved oxygen content is more sufficient.

2. Sowing and management

1. How to sow

①, sowing date: February to August

②, sowing rate: 3 kg / mu, adjust the sowing rate according to the germination rate of millet grass, through the germination experiment, we can not only distinguish the quality of millet grass species, but also grasp the sowing rate.

③, sowing method: drain the pond water before sowing, and then spread millet grass seeds or millet grass seeds after sprouting evenly in the place where the species is planted. In general, the area of millet grass planted in crayfish ponds accounts for only 60% of the whole pond, with a row spacing of 4 meters every 6 meters wide.

Scrape a layer of mud as much as possible after sowing to prevent bird damage, such as planting millet grass by transplanting, it can be transplanted when millet seedlings grow to 20 centimeters.

2. Management of millet grass

In management, it is mainly to prevent drought and waterlogging, to ensure that the bottom of the pond is often wet or there is a small amount of shallow water (not too much stagnant water), and to add water or drain in time according to the growth status of millet grass in the process of growth. in case the stagnant water is too high and drowns the millet grass or because the water level is too shallow, the millet grass loses to death due to drought.

Crayfish culture should be considered from the crayfish growth environment and demand, the living environment determines the production, but also determines the quality of crayfish, but also determines the management technology of managers. The so-called "high input and high output", the high yield of many agricultural products is not directly related to the high output value! High output value is achieved through continuous ideological and ideological improvement and technological innovation, therefore, we need our agricultural people to "change" in many ways, establish new methods, new technologies, and so on. May all agricultural people have both a bumper harvest and a good harvest!
