Embodiment Construction

[0012] 1. Select 10 acres of clean seawater shoal ponds, and release seedlings between February 10 and 30;

[0013] 2. 50 kg of razor clam seedlings with a specification of 6000 grains / kg per mu;

[0014] 3. Use 200 kg of ammoniated fermented organic fertilizer, 5 kg of diammonium phosphate and 5 kg of superphosphate per mu to fertilize and water;

[0015] 4. The water level of the pond is controlled at 30 to 50 cm. In the middle of each month, according to the water quality, a small amount of water is added to keep the water level relatively stable, and fertilization is carried out once;

[0016] 5. The salinity of the water quality is controlled to be 20‰-30‰, and the pH value is 7-8.6.

[0017] More than 5,000 kilograms of clam clams can be produced when harvested.

Abstract

The invention relates to shallow pond culture technology for sinonovacula constricta lamarck, which is characterized by comprising the following steps: putting young sinonovacula constricta lamarck from February 10 to February 30 every year, wherein the amount of the young sinonovacula constricta is 50kg (6,000 babies / kg) per mu; fertilizing water by using 200kg of ammonifying fermented organic fertilizer, 5kg of diammonium phosphate and 5kg of superphosphate per mu; controlling the depth of the water level to be 30-50cm; adding a small amount of water in the middle of every month according to water conditions so as to keep the stability of the water level, and fertilizing the water for one time; and controlling the salinity of water to be 2-3 percent and controlling the pH to be 7-8.6. The technique solves the problems of low yield and poor economic return of the shallow culture of the sinonovacula constricta lamarck or the mixed culture of shrimps and shellfish, and is suitable for seawater shallow pond culture of the sinonovacula constricta Lamarck.

Description

technical field [0001] The invention relates to the field of seafood culture, in particular to a high-yield and high-efficiency culture technology for razor clam shoal ponds. Background technique [0002] At present, in the cultivation of razor clams, shoal cultivation or polyculture of shrimp and shellfish in ponds is generally adopted, which has low yield and poor benefit. Contents of the invention [0003] The invention aims to solve the problems of low output and poor benefit of the current razor razor shoal culture or mixed shrimp and shellfish culture in ponds, and proposes a high-yield and high-efficiency razor razor shoal pond culture technology. [0004] The present invention is for solving the above-mentioned technical problem, and the adopted technical solution is, a kind of culture technology of hanging razor clam shoal pond, and its special feature is: [0005] 1. Seedling release time: from February 10th to 30th every year; [0006] 2. The amount of seedlin...
