营养液浓度对秸秆基质栽培黄瓜生长和产量的影响

以津优2号黄瓜为试验材料,研究了不同浓度的营养液对小麦秸秆基质栽培黄瓜的生长势、叶片光合特征、产量的影响.结果表明,以50%秸秆 50%蛭石为基质,浇l倍营养液黄瓜的株高、茎粗、叶片数、叶面积、叶片叶绿素含量、光合速率、蒸腾速率、产量最高.

The Influence of Solution Concentration upon Growth and Yield of Cucumber Cultivated in Stalks Substrate

With cucumber cultivar No.2 Jinyou as the experimental material, the influence of different concentration nutrient solution upon the growth vigor, leaf photosynthetic property and yield of cucumber cultivated in wheat stalks substrate were studied. The results showed that plant height, stem thickness, leaf number, leaf area, leaf chlorophyll content, net photosynthetic rate and transpiration rate of cucumber were highest when they were irrigated 1 dose concentration solution in 50% stalks 50% vermiculite substrate. The results provided bases for fertilizer need of cucumber cultivated in stalks substrate.
