摘要
通过对淀粉废水沉降底泥复肥的生物试验 ,证实了利用工业废水的资源化产物进行农业生态建设的切实可行性。该复合肥实现了水稻营养生长和生殖生长的协调统一 ,使平均每穗实粒数这一重要产量构成因子表现突出 ,因而产量也较高 。
Rice was grown in a pot experiment, in which a prepared sludge compound fertilizer was applied, to investigate the feasibility of protect agricultural ecology with compound fertilizer produced by utilizing urban industrial wasted. Balanced vegetative and reproductive growth was achieved in the rice plants, reflected in significantly higher number of filled grians per spike, an important yield-contributing factor of rice crops. Moderate rate of the compound fertilizer gave the best results in yield increase.
