有人认为:池塘养蟹不宜放养水花生,以防止水温升高时败坏水质。但我们的试验结果并非如此。1987年我们在26个河蟹生产试验点上,于4月份从水沟中采取水花生分块培植在放养河蟹的池塘中以后,每10天检查1次水花生中有无河蟹,晚上观察河蟹在水花生簇丛中摄食情况。结果发现,放养河蟹的池塘中培植水花生能够促使河蟹蜕壳生长。我们认为水花生能够促使河蟹蜕壳生长是由于它具有以下作用。 1.食物作用。水花生对养蟹的食物作用有三种情况,一是河蟹大量地摄取水花生茎上附着的藻类,不论幼蟹还是成蟹都是如
Some people think: pond crabs should not stocking water peanuts, to prevent the water temperature corrupt water quality. But our test result is not the case. In 1987, we tested crabs in peanuts at 26 crab production test points in April and collected peanuts from the ditches in April after stocking crabs and crabs Water Peanut cluster feeding situation. The results showed that the cultivation of water and peanuts in ponds stocking crabs can promote the growth of crabs molting. We think water peanuts can promote the growth of crabs because of its following functions.
