以“津优10号”黄瓜品种为试材,采用无土基质袋式栽培,设置3个单株水分(105、150、195L,处理代号W1、W2、W3)、3个单株肥料(65、90、117g,处理代号F1、F2、F3)双因素交叉共9个处理,对不同水肥处理下黄瓜产量、水分利用率和营养品质进行了比较。结果表明:结瓜早期F2W1处理既节约水肥,又不影响产量,中期和后期产量均是F3W2和F3W3处理最高,其次是F2W2和F2W1处理,水、肥、水×肥对早期产量无显著影响,对中期和后期产量影响显著,影响大小为肥>水×肥>水;水分利用率在同一水分条件下,F3>F2>F1,在同一肥力水平下,W1>W2>W3;采用主成分分析法对营养品质进行多目标综合比评价,综合评价值前3名为F1W1、F2W1和F2W2;综合以上分析,F2W2和F2W1既能保证品质,又不过多的降低产量,为最优组合。
With “Jinyou 10” cucumber variety as test material, soilless bag culture was used to set three single plants moisture (105, 150, 195L, treatment code W1, W2, W3) (65,90,117 g, treatment code F1, F2, F3) were used to compare the yield, water use efficiency and nutritional quality of cucumber under different water and fertilizer treatments. The results showed that: early F2W1 treatment both water and fertilizer saving, without affecting the yield, the middle and late yield F3W2 and F3W3 were the highest treatment, followed by F2W2 and F2W1 treatment, water, fertilizer, water × fertilizer had no significant effect on the early yield, And had significant effects on the yield in the middle and later stages with the effect size of fertilizer> water × fertilizer> water; under the same water condition, F3> F2> F1, W1> W2> W3 at the same fertility level; According to the above analysis, F2W2 and F2W1 can not only ensure the quality, but also reduce the yield too much, which is the optimal combination.
