Preparation method for multifunctional fungicide compound promoting shrimp and crab exuviations and application method for same

Abstract

The invention provides a preparation method for multifunctional fungicide compound promoting shrimp and crab exuviation and an application method for the same. The multifunctional fungicide compound promoting shrimp and crab exuviationcan promote shrimp and crab exuviation and growth, and can also purify water and promote aquatic plant to root and germinate and improve stress resistance; and culturing ecological environment can be improved. The multifunctional fungicide compound promoting shrimp and crab exuviation can improve shrimp and crab existing water area ecology, and can also adjust activities of enzyme and methyl farnesoate in the shrimps and the crabs; and molting hormone secretion, chitinous synthesis, shrimp and crab culturing survival rate, culturing specification and output can be improved. In the preparation method for multifunctional fungicide compound promoting shrimp and crab exuviation and an application method for the same, the technology is simple and easy to conduct; high production efficient, low application cost, simple operation and easy achievement can be realized; the product quality is stable, the application is convenient, great adaptability can be realized; and high promotion and application values can be achieved.

Description

technical field [0001] The invention belongs to the field of agricultural science and technology, and in particular relates to a method for preparing and applying a compound for shrimp and crab molting and breeding ecological improvement, especially but not limited to shrimp and crab farming. Background technique [0002] There is a significant correlation between shrimp and crab molting and growth. Shrimp and crab individuals also continue to grow up with the increase in the number of molting times, and their weight increases to varying degrees after each molting. The higher the frequency of molting, The shorter the molting cycle, the faster the growth. Therefore, making shrimp and crabs molting quickly or shortening the molting cycle is an effective way to grow large-scale commercial shrimps and crabs and increase aquaculture production. It is also the hope of shrimp and crab farming industry. The results obtained. [0003] Shrimp and crab molting usually require a good...

Problems solved by technology

In order to improve the production and benefits of breeding, the current practice is to increase the stocking density in order to pursue higher breeding production. However, the water quality tends to deteriorate during high-density farming, and the incidence of diseases remains high. The subsequent investment in disease control drugs It will also aggravate the disorder of physiological metabolism in shrimp and crabs, and the normal moulting of shrimps and crabs will be disturbed

At the same time, when the ecological balance of the aquaculture waters is damaged, the normal feeding of shrimp and crabs will be affected to a large extent, and the reduction of nutrient accumulation will inevitably lead to the failure of shrimp and crab moulting. Therefore, the shrimp and crab aquaculture industry It is urgent to invent a product that can restore the ecology of aquaculture waters and restore the appetite of shrimp and crabs under the current situation
