一种有机矿质复合剂对小米辣育苗效果及基质酶活性的影响

为明确蔬菜工厂化育苗中一种新型有机矿质复合材料对小米辣(Capsicum frutescens L.)幼苗生长质量及基质酶活性的影响,采用单因素试验,设置5个不同浓度并以商品育苗基质为原料进行小米辣育苗盘育苗,测定小米辣生长相关指标和基质酶活性.结果表明,15 g·L-1和30 g·L-1处理的幼苗干质量及生长函数显著...

Effects of an organic mineral compound on the seedling quality of chili pepper(Capsicum frutescens L.)and soil substrate enzyme activity

A experiment with 5 treatment levels was conducted to explore the effects of a new organic mineral material on the growth quality of chili pepper(Capsicum frutescens L.)seedlings and the substance enzymes activity in vegetable factory seedlings,using commercial seedling production soil mixture.The growth-related indexes and soil substrate enzyme activities were assayed.The results show that dry weight and growth rate were significantly higher for 15 g·L^-1and 30 g·L^-1 treatments,but the emergence rate was lower than CK.Soluble sugar content in leaf and root,and root vitality of the 15 g·L^-1 treatment were 9.21%,105.48%and 84.92%higher than CK.Soil substrate enzyme activities,except for catalase activity lower than CK,invertase,urease,and acid/alkaline phosphatase for the 15 g·L^-1 treatment were significantly higher than control.Under the test conditions,the 15 g·L^-1 organic mineral compound can promote the growth of chili pepper seedling and improve the soil substrate enzyme activity.This provides a new venue for high quality chili pepper seedling production.
