沼液浸种可以防止水稻低温烂秧,提高成秧率和秧苗素质,增加粮食产量,早在80年代初,就已为我省农民在沼气综合利用的实践中所认识。1988年省农科院水稻研究所承担了农业部环保能源司下达的“沼液浸种防止水稻烂秧机理及其应用研究”课题,经过科研人员的大量科学试验,基本弄清了其机理。结果表明:沼液浸种能提高水稻幼苗的耐冷能力,通过一系列的试验分析表明,沼液含有水稻所需要的氮、磷、钾等微量元素和激素类物质等,在低温协迫下,能相对提高幼苗的存活率,缓解幼苗低温伤害,它的生理效应是多方面的,同时试验证明,采用沼液浸水稻种还能提高秧苗素质和成秧率,提高稻谷产量。为了在大面积的生产实践中得到进一步的论证,尽快推广应用,为“两高一
Biogas slurry soaking can prevent low-temperature rotten rice seedlings, improve seedling yield and seedling quality, increase food production, as early as the early 1980s, has been for our province farmers in the comprehensive utilization of biogas practices recognized. 1988 Provincial Academy of Agricultural Sciences Rice Research Institute assumed the Ministry of Agriculture Environmental Protection Department issued the “biogas slurry soaked rice seedling prevention mechanism and its application research” subject, after a large number of scientific research scientists, the basic clarify the mechanism. The results showed that soaking biogas slurry could increase the cold tolerance ability of rice seedlings. Through a series of experiments, it showed that biogas slurry contains the nitrogen, phosphorus, potassium and other trace elements and hormones needed by rice, Relatively improve the survival rate of seedlings to alleviate the seedling hypothermia, its physiological effects are many, at the same time, experiments show that the use of biogas slurry soaking seedlings can improve the quality of seedlings and the rate of seedlings, improve rice yield. In order to get further demonstration in a large area of production practice, popularize and apply as soon as possible,
