| 中文摘要: |
| 本试验以黄瓜品种“博特209”为试材，采用基质盆栽，共设置4个灌水下限处理，分别为田间持水量的50%（A）、60%（B）、70%（C）、80%（D），灌水上限统一设定为田间持水量的90%，研究不同灌水下限对基质栽培黄瓜生长、产量和品质的影响，并运用主成分分析法对4个处理黄瓜的生长、产量及品质相关的22个指标进行了综合评价。结果表明：处理D的株高和叶面积显著高于处理A、B和C，株高增幅分别为56.50%、22.51%和11.04%，叶面积增幅分别为92.61%、61.35%和27.87%；处理C的茎粗最大，相较于处理A、B、D分别增加了28.36%、16.91%和18.49%；单果重、单株果数、单株产量及灌水量均以处理D最大；水分利用率以处理C最高，相较于处理A、B、D分别增高了33.14%、13.23%和10.30%。处理C与处理D的瓜粗、含水量及商品瓜率无显著差异，但相对于处理A和B则分别显著增加了19.17%和10.81%、0.98%和0.45%、66.70%和18.21%。处理C的可溶性蛋白和可溶性糖含量显著高于其他处理，而硝酸盐含量显著低于其他处理；黄瓜果实中全K和全Ca含量以处理C最高，相较于处理A、B和D，其全K和全Ca的增幅分别为35.20%和11.19%、3.81%和11.19%、1.06%和6.43%。经主成分分析及综合评价，4个处理的得分从高到低依次为：处理C、处理D、处理B、处理A。 |

| In this experiment, the cucumber variety, Bote 209, was used as test material, and four irrigation water limit treatments were set in potted medium. They were 50%, 60%, 70%, and 80% of field water holding capacity. The irrigation water limit was set to 90% of field water holding capacity by A, B, C, and D. The effects of different irrigation water limits on the growth, yield, and quality of cucumber under substrate cultivation were studied. In order to evaluate and select the suitable irrigation water limits for cucumber under substrate cultivation more scientifically and reasonably, the principal component analysis was used to evaluate 22 indexes related to the growth, yield and quality of cucumber under four treatments.The results showed that the plant height of treatment D was significantly higher than that of treatment A, B, and C by 56.50%, 22.51%, and 11.04%, respectively. The leaf area of treatment D was also significantly higher than that of treatment A, B, and C by 92.61%, 61.35%, and 27.87%. Compared with treatment A, B, and D, the stem diameter of treatment C was the largest, which increased by 28.36%, 16.91%, and 18.49%, respectively.The single fruit weight, fruit number per plant, yield per plant, and irrigation amount of treatment D were the largest, while the water use efficiency of treatment C was the highest, which increased by 33.14%, 13.23%, and 10.30% compared with treatment A, B, and D.Compared with treatment A and B, the three indexes of treatment C were significantly increased by 19.17% and 10.81%, 0.98% and 0.45%, 66.70% and 18.21%, respectively.The contents of soluble protein and soluble sugar in treatment C were significantly higher than those in other treatments, while nitrate content was significantly lower in treatment C. Compared with treatment A, B, D, the contents of total K and Ca increased by 35.20% and 11.19%, 3.81% and 11.19%, 1.06% and 6.43%, respectively. After principal component analysis and comprehensive evaluation, the scores of the four treatments from high to low were as follows: C, D, B, and A. |
