利用放养夏花鱼种池的空闲时间,在池底种植稗草,既能改善池塘的底质条件,又能收获稗草。稗草除鲜割饲养成鱼外,还可淹青培育鱼种,是一种花钱少、成本低,利用空闲季节挖掘鱼种池生产潜力的好办法。 一、稗草的种植。4—7月均可播种。播时排于池水,将稗草籽均匀撒在池底淤泥上,然后用木板轻轻地将池泥刮一下,使草籽入土,每亩用种量5公斤左右,播后保持泥土湿润。如果雨后池底积水,应开浅沟排水,防止积水淹没幼芽。稗草拔节后,可保持浅水。稗草一般可长至1米左右,亩产鲜草约5000公斤,可收获部分稗草用来饲养成鱼。
The use of stocking summer flower fish pond free time, planted barnyard grass at the bottom, both to improve the pond’s substrate conditions, but also harvest barnyard grass. In addition to feeding barnyard grass into fresh cut fish, but also submerged breeding of fish species, is a less cost, low cost, the use of idle seasons to tap the production potential of fish ponds a good way. First, the cultivation of barnyard grass. April-July can be sown. Sowing row in the pool of water, the barnyard grass seeds evenly sprinkled on the pool bottom of the mud, and then gently scrape the pool of mud to make grass seeds into the soil, the amount of about 5 kg per mu, after sowing to keep the soil moist. If the bottom of the pool water after the rain, should open the shallow ditch drainage to prevent flooding submerged sprouts. Barnyard grass after the jointing, can keep shallow water. Barnyard grass can generally grow to about 1 m, about 5000 kg of fresh grass per mu, barnyard grass can be harvested for raising adult fish.
