菇渣等复合基质对番茄育苗效果的影响

摘要

研究几种复合基质对番茄幼苗生长的影响.结果表明,番茄育苗效果最好的基质配方是S1和S2处理[V(腐熟菇渣):V(蛭石):V(珍珠岩)=1:1:1、V(腐熟菇渣):V(蛭石):V(珍珠岩)=2:1;2],番茄出苗快、出苗率高.S1和S2的茎粗、干质量、根冠比和壮苗指数都显著大于CK和其他商品基质.可以用腐熟菇渣替代草炭进行番茄穴盘大面积育苗.%The effect of several compound substrate on tomato seedling growth was researched.The result showed that the best efficiency prescription of compound substrate of tomato seedling was treatments S1 and S2 (1/3 the rotten mushroom residue + 1/3 vermiculite + 1/3 pertilite, 2/5 the rotten mushroom residue +1/5 vermiculite +2/5 pertilite).They were volumetric ratio.The emergence of tomato seedlings was fast, and the rate of emergence of seedlings was complete.The treatments of S1 and S2 of diameter of stem, plant dry weight, shoot and root ratio and healthy index were marked beyond CK and other commodity substrate.Compound substrate of the rotten mushroom residue could be replaced with grass peat for large area tomato pots culture of seedling.
