黄瓜免营养液无土育苗基质组配研究

摘要

利用菇渣部分替代草炭，与蛭石、珍珠岩组配，形成黄瓜优化育苗基质，在此基础上，加入不同用量缓释肥进行黄瓜穴盘育苗试验，结果表明：在草炭+菇渣+蛭石+珍珠岩=2∶3∶2∶3(V∶ V∶ V∶ V)基础上，添加1．71~2．14 g·L -1缓释复合肥(N - P2 O5- K2 O =14-14-14)，可满足黄瓜整个苗期对养分的需求，实现全程免营养液管理，培育出优质幼苗。%The mushroom residue compost, peat, vermiculite and perlite were used to compose different complex media for cu-cumber seedling production by adding different dosage of slow release compound fertilizer. The results showed that it could meet the nutrient needs of cucumber seedling without nutrient solution fertigation by adding slow release fertilizer (N - P2 O5 - K2 O= 14 - 14 - 14) at 1. 71 ~ 2. 14 g·L - 1 into complex media of peat, mushroom residues, vermiculite and perlite at a volume ratio of 2∶ 3∶ 2∶ 3 (V∶ V∶ V∶ V) and cultivate high quality seedlings.
