| 摘 要： | 试验研究了灌溉水质与土壤初始含盐率对滴灌棉花出苗率的影响.试验结果表明,土壤不舍盐时,灌溉水质d对内行棉花出苗率影响不显著,对外行棉花出苗率影响显著;自来水处理的内行与外行棉花出苗率均大于微成水处理;在4种微咸水中,EC小的水质对应的出苗率高,EC值相同时,SAR值小的内行出苗率高,SAR值大的外行出苗率高.当土壤舍盐...

| Abstract: | Base on the result of experiment,impacts of initial soil salt content and irrigation water quality on cotton seedling emergence under drip irrigation is analyzed.The results indicated that when soil is salt free,water quality affects outer row cotton emergence significantly,whereas the effect of water quality on inner row cotton emergence is not significant.The check treatments irrigated with tap water get the biggest value of inner and outer row emergence rate among all water quality levels.When irrigated ... |
