生物有机肥在水稻上的应用研究

Application of Biological Organic Fertilizer in Rice Production

为验证生物有机肥在水稻生产中的应用效果优于常规农用化肥,以杂交水稻陆两优996为材料,进行了生物有机肥的田间肥效对比试验。结果表明,与常规农用化肥相比,施用有机肥可使水稻生育期缩短2 d,还可提高水稻的有效穗数和结实率,促进水稻籽粒灌浆结实,增加千粒重;从而使水稻增产10.52%-12.21%,农民增收79.61-149.50元/667m2。另外,有机肥还可增强水稻的抗倒性和对病虫害的抗性,有利于机械化收割和病虫害防治。这表明生物有机肥在水稻生产中的应用效果较好,可替代常规农用化肥推广使用。

For validating the application effect of biological organic fertilizer is superior to the ordinary fertilizer in rice production, using the hybrid rice Luliangyou 996 as material, and a contrast test of biological organic fertilizer was conducted in paddy field trials. The results showed that： with organic fertilizer application, rice growth period was 2 d shorter, the rice panicles and seed setting rate were improved,the rice grain filling and 1000 grain weight were promoted. It can increase the rate of rice yield by 10.52%-12.21%, which will contribute to the improvement of farmers income at 79.61-149.50 yuan per 667 m2. Besides, biological organic fertilizer application can improve the lodging resistance and disease resistance, and it is conducive to mechanized harvesting and pest control. Therefore, we can conclude that biological organic fertilizer can replace the conventional agricultural fertilizer and expend the use of it.
