番茄穴盘育苗低成本无土基质筛选的研究

利用废菇料、玉米秸、锯末、炉渣、牛粪、珍珠岩、蛭石、细沙等原材料,按照不同的组合和比例配制成10种复合基质,用于番茄（满田2185）穴盘育苗,研究不同基质栽培番茄的幼苗长势和质量,以筛选出用于番茄穴盘育苗的低成本无土基质。结果表明：基质3（珍珠岩、蛭石体积比为1∶1）和基质4（草炭、蛭石、废菇料体积比为1∶1∶1）的育苗效果明显优于CK（草炭、蛭石体积比为2∶1）,番茄幼苗表现生长势壮、干物质积累快、壮苗指数大;基质6（废菇料、蛭石、珍珠岩体积比为2∶1∶1）和基质10（废菇料、蛭石体积比为2∶1）的育苗效果与CK相当,可以替代CK进行育苗。

Study on the Selection of Low-cost Soilless Nursery Substrates for Tomato Plug Seedling

Taking waste mushroom material,corn stalk,sawdust,slag,cow muck,perlite,vermiculite,and fine sand as materials,10 nursery substrates for tomato plug seedling were composed.On studying the growth and quality of seedlings,favorable low-cost soilless substrates were selected.The results showed that in substrate 3（the volume ratio of perlite to vermiculite is 1∶ 1）and in substrate 4（the volume ratio of peatmoss to vermiculite to waste mushroom is 1∶ 1∶ 1） tomatoes grew strongly,dry matter accumulated faster,and good seedling index were higher,which were significantly better than in CK（the volume ratio of peatmoss to vermiculite is 2∶ 1）;the quality of seedlings in substrate 6（the volume ratio of waste mushroom to vermiculite to pearlite is 2∶ 1∶ 1） and in substrate 10（the volume ratio of waste mushroom to vermiculite is 2∶ 1） was equivalent to CK.
