| 摘 要： | 通过室内模拟试验田间试验,了解不同土壤含水量、对不同塑料薄膜覆盖对辣椒种子发芽的影响,结果表明,最适宜于辣椒种子发芽及幼苗生长的土壤含水量范围为35%～40%,适宜范围为30%～50%。土壤含水量等于或低于25%,或者等于或高于55%,对辣椒种子的正常发芽及幼苗生长造成影响。在没有水分补充的情况下,黑色塑料薄膜对田间表层土壤含水量的保持效果优于无色塑料薄膜,有利于辣椒种子的发芽。

| Abstract: | Effects of different soil moisture on seed germination and seedling growth of hot pepper and the effects of mulching different plastic films on soil moisture were studied in the experiment.The result showed the soil moisture of helping seed germination and seedling growth is 35%-40%.The soil moisture of 25% low and 55% high is bad for the seedling growth and seed germination.Without water supplying the effects of mulching black plastic films on keeping soil moisture is better than that of mulching white plastic films. |
