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13~16d、22d后出现增长速度较快的特点;“极品”在播种后13~19d、25d后出现增长速度较快的特点。
Taking three kinds of melon varieties of early, middle and late maturity as experimental materials, the characteristics of root morphological changes of different melon varieties at seedling stage were studied by matrix cultivation method. The results showed that there were differences among the three cultivars due to the differences among the cultivars, the root volume, the length of the main root, the number and total length of the primary and secondary lateral roots, and the values of fresh weight and dry weight of the three cultivars. . “Dian ” and “High resistance ” showed the rapid growth after 13 ~ 16d and 22d after sowing; “Need” increased rapidly after 13 ~ 19d and 25d after sowing Features.
