摘　　要：为探寻苹果树修剪枝条资源化快速利用的方法,以黄瓜(津研四号)为试材,分别测定了苹果枝条培养木霉T11-W后(处理木屑)和同时添加木霉对盆栽黄瓜幼苗生长发育的影响,并与不同添加量的未处理苹果枝条(原木屑)处理和单独木霉T11-W处理进行对比。结果显示:单独木霉T11-W处理对黄瓜幼苗生长促进效应最为显著;原木屑质量分数为0.7%时,添加木霉可改善其对根长的抑制,并能进一步提高根的干物质量;木霉+木屑处理(处理木屑或原木屑)综合评价虽不如单独木霉T11-W处理,但根冠比最高;原木屑处理用量0.35%时,对黄瓜幼苗生长的综合促进作用弱于空白对照,用量0.7%时,促进作用高于空白对照,表明原木屑添加量大,利于黄瓜幼苗生长;木屑在0.35%使用量时,处理木屑对黄瓜幼苗的促生长作用优于原木屑处理。To explore rapid utilization methodsfor pruning apple branches,cucumber(Jinyan No.4)was used as a test material to study the effects of Trichoderma harzianum T11-W and apple branch sawdust on its seedling growth.T.harzianum T11-W was added to the sawdust in advance in one group(this was considered treated sawdust),whereas the other group involved the simultaneous addition of T.harzianum T11-W to sawdust.These two groups were compared with untreated apple branches(raw sawdust)and T.harzianum T11-W alone.Results showed that T.harzianum T11-W exhibited the most significant growth-promoting effect on cucumber seedlings,and when the mass fraction of sawdust was 0.7%,the root length inhibition of sawdust was weakened and the dry weight of its root was further increased by adding T.harzianum T11-W.Although the comprehensive evaluation of Trichoderma with sawdust treatment(treated sawdust or raw sawdust)was not as good as that of T.harzianum T11-W treatment alone,they have the highest root-cap ratio.When the raw sawdust dosage was 0.35%,the promotion of cucumber seedling growth was weaker than that of the control group that did not undergo any treatment.When the dose was 0.7%,the growth-promoting effect was higher than that of the above-mentioned control group,indicating that increasing the amount of raw sawdust facilitated cucumber seedling growth.When the sawdust dosage was 0.35%,the growth-promoting effect of treated sawdust on cucumber seedlings was better than that of raw sawdust.
