摘要
将蛭石、炉渣灰、细沙、草炭和有机肥等按照不同组合与配比组成复合基质 ,用于番茄穴盘育苗。结果表明 ,不同基质对番茄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分别为蛭石∶有机肥∶炉渣灰 =5∶3∶2 ,有机肥∶细沙 =5∶5的育苗效果次于T2 ,但优于CK 。
Several compound nursery substrates were composed of vermiculite,cinder ash,fine sand,peat and organic fertilizer in different combinations and mixing ratios and then used for raising tomato seedlings in 72 hole seed pans.According to the results,the effects of these substrates on growth of young tomato seedlings are significantly different.Substrate T 2(vermiculite+organic fertilizer+cinder ash in the ratio 7∶2∶1)has the best effect,obviously better than CK substrate(peat∶vermiculite in the ratio 2∶1). It yields tomato seedlings with rapid growth,quick dry matter accumulation and great health index and therefore can substitute for CK substrate in factory seedlings raising with holey seed pans.As for substrate T 3(vermiculite+organic fertilizer+cinder ash in the ratio 5∶3∶2)and T 7(organic fertilizer+fine sand in the ratio 5∶5)being all less effective than T 2,but more effective than CK,they have also value in use.
