- 摘要:
- 以黄瓜为试材,研究了不同深翻深度并添加秸秆基质对黄瓜根系生长相关因子及产量的影响。结果表明:不同深翻深度并添加秸秆可以提高黄瓜根系数、根体积、光合速率、20~40 cm土层根比例和产量,降低20~40 cm土壤容重;土壤深翻80 cm并添加1.20 kg/m2秸秆效果最为显著,与对照相比,根系数提高69.46%,光合速率提高65.79%,单株产量提高26.70%。
- Abstract:
- he cucumber was selected as material,the effect of different deep plowing depthes and straw substrate regulation on related factors of cucumber roots growth in greenhouse was studied.The results showed that deep tillage and straw substrate improved the root factor,root volume,photosynthetic rate,20-40 cm soil root proportion and yield,and reduced 20-40 cm soil bulk density.Deep plowing 80 cm and straw substrate regulation 1.20 kg/m2 had the most significant effect,compared with the control,increased root coefficient 69.46%,photosynthetic rate 65.79%,per plant yield 26.70%.
