沼肥对水稻增产作用的研究

本文根据本所4年沼肥肥效定位试验结果,证实沼气发酵剩余物是一种缓速兼性的优质有机肥料。不仅沼液、浮渣、沉渣单独施用对水稻有较为显著的增产作用,而且沼液、浮渣、沉渣合并施用对水稻的增产作用更为显著,因此,必须纠正某些地方“弃渣用液”或“弃液用渣”的片面施用沼肥的现象,大力提倡全沼肥的合理施用。

Study on the Effect of Biogas Fertilizer for Improving the Rice Yield

Results of fixed experiments of biogas fertilizer carried out in this institute for four years proved that biogas fertilizer is an organic fertilizer of high quality with both quick and slow effect. Not only biogas slurry, sludge or residue has remarkable effect on improving the rice yield, but the application of the mixture of biogas fertilizer has still greater effect on improving the rice yield, consequently, cases of "only apply biogas slurry but not the sludge" or "only apply biogas but not the slurry" in some areas should be transformed and reasonable application of biogas fertilizer should be energetically promoted.
