中文摘要	为了研究膜下滴灌调亏菘蓝主要农艺性状对药材产量的影响,对菘蓝在营养生长期和肉质根生长期实施亏缺灌溉处理,测定了菘蓝的10个主要农艺性状。采用相关、回归、通径分析等统计学方法,分析了各农艺性状间的相关关系。结果表明:亏水处理对菘蓝的主要农艺性状存在一定程度的影响,变异系数CV值在5.45% ~ 17.19%之间,菘蓝叶和根产量的CV值分别为13.14%、16.28%;菘蓝叶和根产量同除根冠比外的其他农艺性状间的相关系数为正,均达显著水平 (P < 0.05);菘蓝叶和根产量分别与农艺性状之间建立回归模型,经统计学检验均为极显著水平(P < 0.01),其决定系数为0.996、0.971;通径分析模型得出株高(0.498) 、主根长(0.630)是影响叶产量的主要农艺性状,而影响根产量的关键农艺性状为叶长(0.698) 。因此,在菘蓝的栽培过程中进行亏水处理,在干旱胁迫下协调植株各部分的生物量分配,增加菘蓝植株的株高、叶长和主根长,有利于产量的形成。
英文摘要	In order to study the effects of the main agronomic traits of isatis indigotica on the yield of medicinal materials under mulched drip irrigation based on water deficit (WD),the WD treatment of isatis indigotica in the vegetative growth and fleshy root growth period was carried out,and ten main agronomic traits of isatis indigotica were measured and calculated. Correlation analysis,regression analysis and path analysis were used to analyze the correlation between various agronomic traits. The results showed that the WD treatment had a certain degree of influence on the main agronomic traits of isatis indigotica,with a coefficient of variation (CV ) of 5.45% ~ 17.19%,and the CV values of folium yield and radix yield were 13.14% and 16.28%,respectively. There was a significant positive correlation(P < 0.05) between the coefficient of folium and radix yields and the remaining agronomic traits except for the root - to - shoot ratio. A regression model between the folium and radix yields and agronomic traits was established. With the statistical tests,it was found that both of them reached extremely significant levels(P < 0.01),and the coefficients of determination were 0.996 and 0.971,respectively. Through the path analysis, the main agronomic traits affecting the yield of folium were plant height(0.498) and main root length(0.630),the key agronomic traits affecting the yield of radix were leaf length(0.698). Therefore, in the cultivation process of isatis indigotica,the WD treatment can improve the allocation of biomass in each part of the plant under drought stress,increase the plant height,leaf length and main root length, which ultimately contributes to the formation of yield.
