[0011] Example 1:
[0012] The method of the present invention for cultivating Litopenaeus vannamei in saline-alkali land includes pond preparation, pond cleaning, fertilization, water inflow, fertilization, shed, seedling release, feeding and shrimp harvesting; the pond preparation is specifically as follows:
[0013] The first step is to select a site. The breeding site is selected in a saline-alkali area with water, electricity, convenient transportation, pollution-free, sufficient water source, and convenient water supply and drainage; test before site selection, which is specifically: saline-alkali land for breeding in the future Dig a 1m×1m×1.5m soil pit, introduce water source for breeding, soak for 3~7 days, require measurement of salinity>0.5‰, calcium ion>80mg / L, magnesium ion>150mg / L;
[0014] The second step is pond construction. Rectangular ponds with an area of 100~500 mu, with a length-to-width ratio of 1~2:2~3, a pool depth of 1.5~1.8 meters, and a maximum storage d...
