一、大棚温室建造 拥有充足新鲜、清洁的水源,是搞好河蟹增温养殖的前提。大棚温室应建在较大的池塘边,也可使用井水,但必须有增氧设备。养蟹池建成长方形,东西向,长10～100米,宽4-10米,深1-1.2米,坎、底压实不漏水,不塌边。较大的池塘应布设充气管道,饲养时用气泵从室外充气。为便于起捕和管理,池底可以铺上聚乙烯网片,用土、砖块、木桩、竹竿、铁丝或压膜条把农膜固定好,建成大棚。大棚可建成斜坡
First, greenhouse greenhouse construction has sufficient fresh, clean water, is a good premise of warming crab farming. Greenhouses greenhouse should be built in a larger pond edge, but also the use of well water, but there must be oxygen equipment. Crab pool built into a rectangle, east-west, 10 to 100 meters long, 4-10 meters wide, 1-1.2 meters deep, Hom, compaction at the end watertight, do not slump. Larger ponds should be equipped with inflatable ducts, aerated with gas pumps from outside when reared. In order to facilitate the arrest and management, the bottom of the pool can be covered with polyethylene mesh, with soil, bricks, stakes, bamboo, wire or film strip of plastic sheeting fixed, built into a greenhouse. Greenhouses can be built slopes
