利用沼气发酵残余物——沼渣从事稻田养鱼,可增加秧苗抗病虫害、抗倒伏能力,增加土壤肥力,提高养鱼水质,改良生态环境,从而提高农、渔产量。是一项以养促种、以种带养、养种并举,生态与经济效益显著的综合实用技术。在沼气发达地区农村推广,很受农民欢迎。现将其技术要点介绍如下:一、准备阶段1.清池消毒:清除鱼池中的杂草,放干池水晾池,挖出池中过多的淤泥。然后在每个鱼池的四角挖四个小坑,每池按每亩25—35公斤生石灰或7.5—10公斤漂白粉的标准,将生石灰或漂白粉稀释成糊状,在全池上下泼洒(此时池中须带水7厘米深)。2.培肥:消毒3天后,放去池中消毒废水,注入用纱布或网罩过滤后的新鲜清水,水深约50厘米。
Biogas fermentation residue - biogas residue in paddy fish farming, can increase seedling resistance to pests and diseases, lodging resistance, increase soil fertility and improve fish farming water quality, improve the ecological environment, thereby increasing agricultural and fishery output. It is a comprehensive and practical technology to promote breeding, breeding with seed and seed, breeding simultaneously, and significant ecological and economic benefits. In biogas developed areas of rural promotion, very popular with farmers. Now the technical points are as follows: First, the preparation phase 1. Qingchi disinfection: remove weeds in the pond, put the dry pool water to dry the pool, dug too much pool of mud. Then dig four pits at each corner of each pond, each pond 25-35 kg per acre of lime or 7.5-10 kg of bleaching powder standard, the quick lime or bleach diluted into a paste, splashed down the entire pool (at this time pool In the water to be 7 cm deep). 2. Fertility: 3 days after disinfection, let go of the pool disinfection wastewater, into the fresh water filtered with gauze or net cover, water depth of about 50 cm.
