木霉T11-W及苹果枝条木屑对黄瓜幼苗生长的影响

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。

Effects of Trichoderma harzianum T11-W andapple branch sawdust on cucumber seedling growth

To explore rapid utilization methodsfor pruningapple branches, cucumber (Jinyan No. 4) was used as a test material to studythe effects of Trichoderma harzianum T11-W and apple branch sawdust on itsseedling growth. T. harzianum T11-W was added to the sawdust in advance in onegroup (this was considered treated sawdust), whereas the other group involvedthe simultaneous addition of T. harzianum T11-W to sawdust. These two groupswere compared with untreated apple branches (raw sawdust) and T. harzianumT11-W alone. Results showed that T. harzianum T11-W exhibited the mostsignificant growth-promoting effect on cucumber seedlings, and when the massfraction of sawdust was 0.7%, the root length inhibition of sawdust wasweakened and the dry weight of its root was further increased by adding T.harzianum T11-W. Although the comprehensive evaluation of Trichoderma with sawdusttreatment (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 theraw sawdust dosage was 0.35%, the promotion of cucumber seedling growth wasweaker than that of the control group that did not undergo any treatment. Whenthe dose was 0.7%, the growth-promoting effect was higher than that of theabove-mentioned control group, indicating that increasing the amount of rawsawdust facilitated cucumber seedling growth. When the sawdust dosage was0.35%, the growth-promoting effect of treated sawdust on cucumber seedlings wasbetter than that of raw sawdust.
