| 摘 要： | 研究了无土栽培5个钾肥水平对西葫芦生理特性及产量和品质影响.结果表明,以株施硫酸钾10 g的株高、茎粗、叶面积和根系活力表现最好,且化果率、发病株率低;叶绿素含量、先合速率、气孔导度、细胞间隙CO2浓度、蒸腾速率、单株产量、果实可溶性固形物、可溶性糖、维生素C、可溶性蛋白质和淀粉的含量也最高.当施钾肥水平较低(5 g/株)、偏高(20 g/株)或不施钾肥时,植株光合速率下降,产量与品质降低.

| Abstract: | The five kinds of different potassium nutrients on the physiological characteristics,yield and quality of summer squash in soils culture were studied.The results showed that the plant height,stem diameter,leaf area and root vitality of the best which the individual plant potassium of 10 g/plant,and the rate of fruit,a incidence of strains were low.It was the highest that chlorophyll content,photosynthetic rate,stomatal conductance,intercellular CO2 concentration,the highest transpiration rate and the highes... |
