黄瓜穴盘育苗基质特性及育苗效果的研究

利用蛭石、炉渣灰、细砂、草炭和有机肥等按照不同组合与配比组成复合基质，用于黄瓜穴盘育苗。研究结果表明，不同基质对黄瓜幼苗生长的影响有显著差异，复合基质T2（蛭石：有机肥；炉渣灰＝7：2：1）育苗效果最佳，明显好于CK（草炭：蛭石＝2：1），表现为幼苗生长迅速，干物质积累快，壮苗指数大。因此，T2可代替CK用于工厂化穴盘育苗，T3、T7的育苗效果次于T2，而优于CK，亦具有利用的价值。

THE FEATURES OF SEVERALMEDIA FOR PLUG-SEEDLINGS OF CUCUMBER AND NURSURY EFFECT

Cucumber seedlings were raised in cornpound media,which were composed of vermiculite,coal ash,peat moss,and organic fertilizer,according to different combination and proportion.The results show that different compound media has significant effects on the growth of seedling.The seedlings in T2(70% Vermiculite+20% organic fertilizer+10% coal ash)were the best and much better than CK (Peat moss:Vermiculite=2∶1).They not only grew quickly,accumulated more organic substance,but also had highest vigorous seedlings indicator.In comparison with peat moss,organic fertilizer showed more advantages for cucumber seedlings.Therefore,"T2" is recommended to replace CK in use of factory potting seedlings.The nursury effect of T3 and T7 is just less better than T2,while better than CK,therefore T3 and T7 also are worth using.
