将油菜菜籽饼作为高品质有机肥在水稻田施用替代部分化肥,研究施用有机肥,化肥减半后对水稻产量的影响,为实现水稻大面积化肥减量提供科学依据。试验结果表明,水稻亩施40 kg菜籽饼高品质有机肥、化肥用量较常规施肥减半,比常规施肥亩增产51 kg,增产率8.1%。水稻田施用高品质有机肥能替代部分化肥,且可实现增产增效。
Using rapeseed rapeseed cake as high-quality organic fertilizer to replace part of chemical fertilizers in paddy fields, the effects of applying organic fertilizers and chemical fertilizers on the yield of rice were studied in order to provide a scientific basis for large-scale reduction of chemical fertilizers in rice. The test results showed that the high-quality organic fertilizer with 40 kg rapeseed cake per mu for rice was 50% less fertilizer than conventional fertilization, 51 kg more than the conventional fertilization, and the yield was 8.1%. High-quality organic fertilizers applied to paddy fields can replace part of fertilizers and can increase production and increase efficiency.
