在池塘养蟹中,水草为河蟹的生长发育提供极为有利的生态环境,对河蟹养殖起着重要的增产增效作用。水草在河蟹养殖中的作用具体表现于以下几点:(1)模拟生态环境:河蟹的自然生态环境离不开水草,“蟹大小,看水草”,说的就是水草直接影响着河蟹的生长。在池塘中种植水草可以模拟和营造蟹的生态环境。有利于河蟹快速生长。(2)提供丰富的天然饵料:水草富含蛋白质、粗纤维、矿物质和维生素等河蟹需要的营养物质。池中的水草一方面为河蟹生长提供了大量天然优质的植物性饵料,另一方面还能诱集
Crab in the pond, the water for the growth and development of crabs provide a very favorable ecological environment, play an important crab breeding stimulation effect. The role of aquatic plants in crab farming is manifested in the following aspects: (1) Simulating the ecological environment: The natural ecological environment of crabs can not be separated from the aquatic plants. The “size of crabs and aquatic plants” means that aquatic plants directly affect the growth of crabs. Planting aquatic plants in ponds can simulate and create the ecological environment of crabs. Crab is conducive to the rapid growth. (2) to provide a rich natural food: aquatic plants rich in protein, crude fiber, minerals and vitamins crabs and other nutrients needed. In the pool of water and grass on the one hand for the growth of crab provides a large number of natural high quality plant bait, on the other hand can also trap
