| 摘 要： | 采用盆栽方法以新大豆8号为试验材料,研究了4种土壤水分处理(下限分别为田间持水量的80%、70%、60%、50%)对春大豆根系生长、根系活力和单株产量的影响.结果表明:随着水分亏缺加重,根干重、根系吸收表面积、根伤流、根活力均呈现显著降低的变化趋势,表现为80%>70%>60%>50%;7月20日前后亏缺灌溉降低大豆根...

| Abstract: | Xindadou 8 was used as tested material to study 4 kinds of soil moistures influences(lower limit was 80%,70%,60% and 50% field held) on root system growth,root system vigor and yield of single plant by pot culture method.The results showed that along with water deficit,dry weight,root system absorb superficial area,root bleeding,and root vigor displayed notable lessening trend as 80%> 70%> 60%> 50%;Moreover,the percentage content and accumulating amounts of N,P2O5,K2O and seed yield around July 20th decreas... |
