不同配比香菇菌渣基质对鲜食黄瓜幼苗生长的影响

摘要

Objective] The effects of different compost treatment of Lentinus edodes fungi residues complex substrates on growth of fresh cucumber seedlings were investigated. [Method] Adopting three methods of compost to treated Lentinus edodes fungi residues,“DING FENG 98F1”fresh cucumber seedlings were raised in composite substrates containing fungi residues, peat moss, perlite, vermiculite. [Result] B method had many advantages such as high temperature and short time during compost, and better rotten effect. The physical and chemical properties of T5 and T6 were within allowed limits. But germination rate aside, The plant height ,root length and dry fresh weight and so on of T5 (rotten fungi residue∶perlite∶vermiculite=1∶2∶1) were significantly higher than control (CK). The root-shoot ratio and strong seeding index of T6 (rotten fungi residue∶perlite∶vermiculite=2∶1∶1) were significantly higher than control(CK). [Conclusion] Complex substrate T5 and T6 could be used as soilless substrate used in production on fresh cucumber.%[目的]研究不同堆沤处理香菇菌渣复合基质对鲜食黄瓜幼苗生长的影响。[方法]采用A、B、C 3种堆沤方法对香菇菌渣进行处理，测定和分析发酵过程中菌渣温度和EC值变化，将处理后的菌渣与草炭、珍珠岩、蛭石组成复合基质，并以“鼎丰98F1”鲜食黄瓜为供试品种进行育苗试验。[结果]采用B方法进行堆沤处理温度高时间短，腐熟效果较好；复合基质T5和T6的理化性质基本都在理想基质范围值内；除在出苗率方面低于对照外，处理T5（腐熟菌渣∶珍珠岩∶蛭石＝1∶2∶1）在株高、根长和干鲜重等方面均明显高于对照（CK），处理T6（腐熟菌渣∶珍珠岩∶蛭石＝2∶1∶1）在根冠比和壮苗指数值上均为最大，且明显优于对照（CK）。[结论]复合基质T5和T6可以作为鲜食黄瓜的无土育苗基质在生产中应用。
