摘要
1997～ 1998年对渭北旱塬红富士苹果不同形态钾与水的交互作用、品质效应及耦合模型进行了研究。根据试验测定结果建立了红富士苹果产量、一级果占有率、>80 %果面红色果占有率、可溶性固形物浓度与KCl,K2 SO4 ,H2 O3因素之间的函数模型。通过主因素分析得出各因素对产量及品质的影响顺序为产量 (y1 ) :x3(H2 O) >x2 (K2 SO4 ) >x1 (KCl) ;一级果占有率 (y2 ) :x3(H2 O) >x2 (K2 SO4 ) >x1 (KCl) ;>80 %果面红色果占有率(y3) :x2 (K2 SO4 ) >x1 (KCl) >x3(H2 O) ;可溶性固形物浓度 (y4 ) :x2 (K2 SO4 ) >x1 (KCl) >x3(H2 O)。
Interaction between water and different forms of potassium,quality responses and coupled model of Fuji apple on Weibei rainfed highland in 1997-1998 were studied.According to the results of experiment,the yield,ratio of the first grade fruit,ratio of >80% of red surface fruit and soluble solids density function model were set up.Based on the analysis of main factors of the function model,the yield responses of Fuji apple to the three factors were in order of H 2O>K 2SO 4>KCl,radio of the first grade fruit responses in order of H 2O>K 2SO 4>KCl,ratio of >80% of red surface fruit responses in order of K 2SO 4>KCl>H 2O,and soluble solids density responses in order of K 2SO 4>KCl>H 2O.The comprehensive analysis of laws of interaction betweens water and different forms of potassium and fruit quality responses of Fuji apple on Weibei rainfed highland were carried out.
