【摘要】 锯末、素砂、砂壤等３种基质对葡萄硬枝扦插的催根效应是不同的锯末、素砂对插条的催根数分别比砂壤增加２７％和２３９％，根的长度分别比砂壤增加３４８％和３９％；根的粗度锯末比砂壤增加７８％，素砂比砂壤减少９５％；３种基质催根成活率分别为１００％，９７％，９４％．锯末的保温性、相对含水量、通气性均优于素砂和砂壤，有利于葡萄硬枝扦插催根更多还原

【Abstract】 Sawdusts,pure sands and sandy loams have different root speeding effect on one year old mature cuttaged grape vine. The sped roots of sawdust and pure sands are respectively 27.0 % and 23.9 % higher than that of sandy loam, and the length of roots are respectively 34.8 % and 3.9 % longer than that of loam, and the diameter of roots in sawdusts is 7.8 % wider than that in sandy loams but the diameter of roots in pure sands 9.5 % thinner than that in sandy loams. The survival rates of sped roots are 100 %、97 % and 94 %. The sawdust has better warmth keeping feature, relative moisture content and aerated feature than pure sands and sandy loam. These better characters are more benifical to speed root.更多还原
