The income is stable: the income of paddy rice is 1,000 yuan, and the minimum of crayfish breeding is 1000 yuan. There is a season rice, even if there is no income of crayfish (worst case), 2 to 3 years, even if you do not cast seedlings can catch crayfish.
In order to have a good harvest, the preliminary work of crayfish farming is very important.
Pond transformation: Culture of crayfish is soil quality, water quality and size and size. 1) Soil quality: It cannot be pure sandy soil, sand soil quality should not be preserved; harder soil is also less suitable for the proliferation of seedlings. (2) Water sources: Drilling wells directly from wells where water is not available. (3) Size: The size of Tongkou should be easy to manage (Tangkou is too large to manage, and Tangkou is too small to manage). General pond 10 acres ~ 20 acres is appropriate, 30 acres ~ 50 acres of paddy fields more suitable.
Pond renovation standards: deep ditch, shallow platform, gentle slope. Standard Tongkou should ensure that the water level of the culture can reach 70 cm, which is convenient for production management. 70 cm is both a nutrient layer and a dissolved oxygen layer. In addition, the pond's moss, fertilizer, aeration, or crayfish clams are all related to water depth; water is not deep and it is not conducive to crayfish fishing.
Put seedlings. (1) Xintang mu will be placed at 30 pounds, and Laotang mu will not exceed 20 pounds. (2) Xintang puts 10 pounds for the first mu, and then puts 20 pounds in two days. After the seeding is finished, Quanchiposa “Silver Roseâ€. After 20 days, about 20 pounds of blood is added (this way, 4 batches to 5 batches of seed can be given each year, and a total of 80 pounds to 120 pounds can be seeded).
Crawfish farming has more profit from sales before May, and the proportion of sales profits is as high as 80%. After May, if the prices dropped and the farmers sold them at a low price, it would be a pity that the money would not be earned. Therefore, crayfish are easy to raise, but also careful planning, details are very important.
Trials were started for 30 days and kept for 45 days. Fishing 100 pounds of shrimp, you need to add about 25 pounds of shrimp.
