| 摘 要： | 在砂田条件下,研究有机肥施用量对砂田辣椒生长发育及产量的影响.结果表明:随着有机肥施肥量增加,辣椒生育期延长,株高、叶面积、光合速率和蒸腾速率增长,在施肥量为100 kg/666.7 m2时达到最佳;水分利用率在施肥量为50 kg/666.7 m2时达到最大;施肥量为129.5 kg/666.7 m2时产量最高,为1 879 kg/666.7 m2.因此,砂田辣椒补施有机肥适宜用量为100～150 kg/666.7 m2.

| Abstract: | The experiment was carried on gravel-sand mulched field to study organic fertilizer appropriate using amount on pepper crops as complement of fertilizer.The results showed that fertilizer amount could increase pepper's growth duration,increase plant height,LAI,photosynthetic rate and transpiration rate.The optimal amount of fertilizer was at 100kg/666.7m2 as best;at 50kg/666.7m2 as WUE reached maximum.In addition the apply amount of 129.5kg/666.7m2 fertilizer could achieve the highest yield of 1 879kg/666.7... |
