酒丢糟制作活性有机肥在水稻上的施用试验

Effects of the Active Organic Fertilizer Made of Grain Stillage and Other Additives on Rice Yield

采用二因素饱和D最优设计方法，对酒丢槽制作活性有机肥（以下简称活性有机肥）在水稻上进行了不同基肥和追肥施用量试验。结果表明，活性有机肥作基肥施用效果显著；通过模拟试验和优化选择，提出了水稻产量高于550kg／667m^2的农艺措施为：活性有机肥作基肥用量为25．15～39．72kg／667m^2，追肥用量14．34～22．126kg／667m^2，得到水稻产量高于600kg／667m^2的优化组合5个，其相应的农艺措施为：基肥用量29．06～46．88kg／667m^2，追肥用量9．31～21：12kg／667m^2。

The optimal two-factor saturated D design was conducted to investigate effects of the active organic fertilizer made of grain stillage and other additives on rice yield. The results show that the rice yield can be significantly improved when the active organic fertilizer is applied as the basic manure, the cultivation measure for over 550 kg/667m^2 of rice yield is including applying 25.15-39.72 kg/667m^2 and 14.34-22. 126 kg/667m^2 of the active organic fertilizer as the basic and top manure and the cultivation measure for over 600 kg/667m^2 of rice yield is including applying 29.06- 46. 88 kg/667m^2 and 9.31 -21.12 kg/667m^2 of the active organic fertilizer as the basic and top manure by the established mathematical model.
