进入夏季,鱼池不宜施用基肥,施肥要因肥制宜,根据不同的肥料采用不同的方法。1有机肥施法。每月每亩鱼池施人畜粪便300—500公斤,每次每亩施100公斤,7—10天施肥一次。可采取分小堆堆放和全池泼洒的办法。还可采取搭架施肥法,即用木杆作木架,用柳条箔做底盘,在池中深水区搭成几个架子,将粪肥放在架子上,让其贴近水面,使肥料在水的中上层分解扩散。还可挂袋,即把肥料盛在耐腐烂的袋子中,挂在池塘中深水区的木柱子上贴近水面让其自行分解扩散。搭架和挂袋施肥法,能加快肥料分解速度,使肥料均匀地扩散到整个鱼池中,特别是能保持肥料在池水的上层腐败分解,这样尽管肥料分解快,也不会造成缺氧,使鱼浮头。
Into the summer, fish ponds should not be applied base fertilizer, fertilization should be due to fertilizer system, according to different fertilizers using different methods. 1 organic fertilizer magic. Each month mu animal pond manure excrement 300-500 kg, 100 kg per acre Shi Shi, 7-10 days fertilization time. May be divided into small piles stacked and Quanchiposais approach. Can also take shelves fertilization method, that is, wood for wood, with wicker foil chassis, take a few shelves in the pool of deep water, the manure on the shelf, let it close to the surface, so that fertilizer in the water Middle and upper division and diffusion. Hanging bags can also be used to hold the fertilizer in a decay resistant bag and hang on the wooden posts in deep water in the pond to break down and spread on the water. Shelf and bagging fertilization method, can accelerate the decomposition rate of fertilizer, fertilizer evenly spread throughout the fish ponds, in particular, can keep the decomposition of fertilizer in the upper water corruption, so that despite the rapid decomposition of fertilizers, it will not cause hypoxia, so that Float fish.
