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、20~40cm土层根比例和产量,降低20~40cm土壤容重;土壤深翻80cm并添加1.20kg/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%。
Taking Cucumber as test material, the effects of different depths of submerged depth and addition of straw matrix on growth factors and yield of cucumber roots were studied. The results showed that root depth, root volume, photosynthetic rate, root ratio and yield of 20 ~ 40cm soil layer were increased with different depths and straw additions, and the soil bulk density was reduced by 20 ~ 40cm. Soil was deep-tipped 80cm and straw was added with 1.20kg / m2 Compared with the control, the root coefficient increased by 69.46%, the photosynthetic rate increased by 65.79% and the yield per plant increased by 26.70%.
