研究了在不同土壤相对含水量条件下木薯的农艺性状的表现.结果表明,随着时间的延长,各灌溉处理木薯的株高和径粗都比对照高,其中以苗期和块根成熟期下限田间持水量50%与块根形成期和块根膨大期田间持水量65%的处理表现为最高值.木薯株高和径粗在7月27日至8月16 日间生长速度较高,之后通过灌溉,各灌溉处理木薯的生长率均高于对照,说明水分灌溉对木薯的农艺性状有良好的促进作用.

Under different relative water content in soil,the performance of agronomic traits of cassava was studied.The results showed that the stem length and diameter of cassava in different conditions of irrigation treatment was more significant than the contrast treatment with the extension of time.As the lower limit reaches 50%of field moisture capacity in seedling stage and tuber maturity,and reaches 65% of field moisture capacity in root formation stage and the period of tuber enlargement,the treatments showed the highest value.The stem length and rate of growth of diameter grow faster from July 27th to August 16th.Through irrigation,the growth rate of various cassava treatmens was faster than the contrast treatment,indicating that the water irrigation can promote the economical character of cassava.
