施肥处理和种植密度对出口型毛豆产量的互作效应研究

Interaction of fertilization and density on yield of vegetable soybean for export

采用裂区设计方法,研究了肥料用量与种植密度对出口型毛豆品种台湾753效果的互作效应,结果表明:施肥处理与种植密度可以同时对毛豆产量产生影响,其中在中等地力条件下,每667 m2以施纯N 10 kg、N∶P2O5∶K2O为1∶0.5∶1.3及种植密度为9 000～11 000株最有利于改善产量构成因素,增产率达6.8%～35.4%,同时表明种植密度过高或过低均不利于高产。

The interaction of fertilization and density on yield of vegetable soybean Taiwan753 was studied by split-plot design.The results showed that the yield of vegetable soybean is influenced by fertilization and density. In medium fertile soil, at an application rate of 10 kg per 667m^2 nitrogen fertilizer, N：P2O5：K2O=1：0.5：1.3, and at the 9 000～11 000 plant per 667m^2 density is the best, it can improve the yield components, increase the yield in 6.8%～35.4% compared with other treatments. There were very significant differences existed between treatments. It was also concluded that too high and too low density is not good for increasing the yield with different kinds of treatment of fertilization.
