- 摘要:
- 以早、中、晚熟3个甜瓜品种为试验材料，采用基质栽培的方法，研究了不同甜瓜品种幼苗期根系形态指标的变化特点。结果表明：3个品种由于品种间差异，根体积，主根长度，一、二级侧根数量和总长度以及根系干重、鲜重数值大小均有差异，但均呈现微弧形曲线上升的变化趋势。“地依”和“高抗”在播种后13～16 d、22 d后出现增长速度较快的特点；“极品”在播种后13～19 d、25 d后出现增长速度较快的特点。
- Abstract:
- Taking three muskmelon varieties of early，middle and late different maturity period as experimental materials，adopting the method of matrix cultivation，the change characteristics of root morphology index were studied.The results showed that because of the difference between varieties，root volume，root length，lateral root level one，level number and total length and root dry/fresh weight of numerical size of the there species had differences，but all showed a trend of the change of the micro arc curve.After sowing 13-16 d，22 d the growth of the ‘Diyi’ and ‘Gaokang’ became faster，and so did ‘Jipin’ after sowing 13-19 d，25 d.
