- 摘要:
- 以“津春2号”黄瓜为试材,以小麦作为填闲植物,研究了小麦填闲减量施钾对植株的形态指标、生理指标和产量的影响,以期为小麦填闲栽培模式的合理施肥提供参考依据。结果表明:与不填闲处理比,小麦填闲的植株形态指标以及植株干鲜质量上没有显著差异,但是黄瓜的单株产量上小麦填闲处理显著增加了26.03%,单果质量上提高了15.22%;在黄瓜盛瓜期以及拉秧期,小麦填闲减钾肥处理的植株叶片的光合速率均显著高于不填闲处理。说明小麦填闲减钾肥有利于黄瓜的生长发育。
- Abstract:
- ‘Jinchun No.2’ cucumber was taken as material and the wheat as the catch crop to study the effect of wheat as catch crop with reducing potassium on the growth and photosynthesis of cucumber,with a view to providing a theoretical basis for rational fertilization of catch crop cultivation model.The results showed that there was no significant difference in plant morphology index and plant dry and fresh weight between amended and unamended with wheat treatments,but the yield per plant of cucumber increased significantly by 26.03%,and the single fruit weight increased significantly by 15.22%.In the cucumber melon period and the pull period,the photosynthetic rate of leaves treated with wheat catch crop and reducing potassium fertilizer was significantly higher than that of the no wheat treatment.So the wheat as catch crop with reducing potassium fertilizer was beneficial to the growth and development of cucumber.
