沼液在寒地水稻生产中的应用效果初报

为了建立以沼气为纽带的可循环农业生态模式，有效利用沼液，变废为宝，开展了沼液在寒地水稻生产中应用效果的研究。结果表明，沼液浸种处理能有效地抑制水稻恶苗病的发生和危害，并能改善稻株营养，提高秧苗素质。50％沼液和50％化学氮肥配合施用于本田，增产效果好，分别达到10．8％和8．0％。

Preliminary Investigation on the Biogas Slurry Used in Rice Production in Cold Region

To develop the mode of agricultural ecosystem circle that based on biogas and make biogas slurry more useful, we developed the investigation. It showed that the harm of pathogenic bacteria could be controlled effectively through immersed rice seeds in biogas slurry, and the diathesis of seeding could be improved. 50% biogas slurry and 50% nitrogenous fertilizer was not only the way to raise the rice yield but also one of the best way to produce green rice as well. Biogas slurry used in rice production solved the problems of increasing byproduct,decreasing pesticide and fertilizer and energy,at the same time,relieving the pollution of the environment. Increased the production of rice and improved the quality of rice. It will have great significance for making agricultural ecosystem with harmonious developing between human being and nature.
