| 摘 要： | 在基质栽培条件下，研究了不同营养液浓度对大棚甜瓜生长发育的影响。试验结果表明，甜瓜营养液浓度三段管理（定植—授粉２．０ｍＳ／ｃｍ，授粉—网发生２．５ｍＳ／ｃｍ，网发生一收获３．０ｍＳ／ｃｍ）能促进甜瓜营养生长和生殖生长。营养液浓度增加，甜瓜叶片中磷、钾含量和钾／（钙＋镁）比率提高，但镁含量降低。试验还表明，不同品种甜瓜对营养液浓度具有相同的适应性。

| Abstract: | The effects of different nutrition solution concentrations on the growth and development of muskmelon were studied In substrate culture. The experiment results showed that the vegetative ad reproductive growth of muskmelon was promoted by the three concentration regimes,i. e. 2. 0 mS/cm for planting-pollination,2. 5 mS/cm for pollination-netting and 3. 0 mS/cm for netting-harvest.Higher solution concentrationincreased the concentrations of K,P and K/(Ca Mg),but reduced the concentration of Mg in the leaves of muskmelon.The experiment results also showed that the adaptability of different muskmelon varieties to solution concentrations was similiar |
