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 split-plot design method was used to study the interaction effect of fertilizer amount and planting density on the export-type soybean variety Taiwan 753. The results showed that fertilization and planting density could affect the yield of soybean at the same time. Under medium soil conditions, 667 m2 with Shi Chun N 10 kg, N: P2O5: K2O 1: 0.5: 1.3 and planting density of 9 000 ~ 11 000 The most conducive to improving the yield components, yield increased 6.8% to 35.4%, also shows that planting Density is too high or too low are not conducive to high yield.
