摘要
为探究水肥多因子耦合对樱桃番茄生长、产量、品质等方面的综合调控效果,获取最适水肥因素组合,以灌水量、施N量、施K2O量、施CaO量为试验因子,进行正交旋转组合设计,利用多层次模糊评判方法对表征樱桃番茄生长的4类因素及14类子因素进行综合评判,构建水肥多因子对樱桃番茄综合生长的调控模型。结果表明:当其他因素为中间水平时,樱桃番茄的综合生长随灌水量增加呈线性关系,随施N量、施K2O量、施CaO量的增加均呈开口向下的抛物线关系;灌水量与施K2O量及施CaO量均呈负交互效应;多因子耦合作用中,灌水量、施N量、施K2O量、施CaO量编码值为1.682、0、-0.744、-1.223更有利于樱桃番茄的综合生长;对于不同水平施CaO量而言,灌水量、施N量、施K2O量、施CaO量编码值为1.682、0.521、0.071、-1最有利于樱桃番茄综合生长。灌水量为补充至灌溉上限用量的91.34%~100%、施N量为12.26~13.50 g/株、施K2O量为2.92~5.13 g/株、施CaO量为2.69~4.39 g/株时,多层次模糊综合评判指数有最优区间,最有利于樱桃番茄的综合生长。
In order to explore the comprehensive regulation of growth,yield and quality of cherry tomatoes by multi-factor coupling of water and fertilizer,the optimal combination of water and fertilizer factors was obtained.The orthogonal rotation combination design was carried out with the amounts of irrigation,applied N,applied K2O and applied CaO as test factors,and the multi-level fuzzy evaluation method was used to comprehensively evaluate the four factors and 14 sub-factors for characterization of cherry tomatoes’growth.Finally,the regulation model of water and fertilizer multi-factor on the comprehensive growth of cherry tomatoes was constructed.The results showed that when other factors were at the intermediate level,the comprehensive growth of cherry tomatoes showed a linear relationship with the increase of irrigation amount.With the increase of N application rate,K2O application rate and CaO application rate,the parabolic relationship of the opening was downward.The interaction had a negative interaction effect between the amount of irrigation and the amount of K2O application and CaO application.Among the multi-factor coupling effects,the irrigation,N,K2O and CaO coding value were 1.682,0,-0.744 and-1.223,respectively,which was more conducive to the comprehensive growth of cherry tomatoes;for different levels of CaO application,the irrigation,N,K2O and CaO coding value were 1.682,0.521,0.071 and-1,respectively,which was most conducive to the comprehensive growth of cherry tomatoes.Finally,irrigation volume was the amount of water needed to replenish to the upper irrigation limit of 91.34%~100%,the amount of N applied was 12.26~13.50 g/plant,the amount of applied K2O was 2.92~5.13 g/plant,the amount of applied CaO was 2.69~4.39 g/plant,the multi-level fuzzy comprehensive evaluation value had the optimal interval,which was most beneficial to the comprehensive growth of cherry tomatoes.
