沼液对水稻生育及产量影响效果的初步研究

Study on effect of anaerobic processed liquid of livestock manures on the growth , development and yield of rice

通过对水稻施用沼液,探讨沼液对水稻生长发育、抗病性及产量的影响,结果表明,沼液能促进水稻的生长、增强抗病性,提高产量。特别是经沼液处理后,比化肥处理每667 m2有效穗数增加0.8万条,比对照增加3.4万条。从产量看,经沼液处理每667 m2比化肥处理增产72.0 kg,比对照增产165.8 kg。

The present experiment was conducted to clarify effect of anaerobic processed liquid of livestock manures on the growth, development and yield of rice. Treatments were consist of anaerobic processed liquid of livestock manures（treatmentl）, fertilizer （treatment2） ,water （treatment3）. The results showed that： treatmentl may obviously improve growth and development, strengthen rice resistance, increase yield. Especially effective tassel of treatmentl was 8 000/667 m2 higher than treatment2, 34 000/667 m2 higher than control. Yield of treatmentl increase 720 kg/667 m2 than treatment2, 165.8 kg/667 m2 than control.
