摘要：

以污泥蚓粪、蛭石为原料，按不同体积比例（4∶6、5∶5、6∶4、7∶3）复配成育苗基质W1、W2、W3、W4，采用穴盘育苗试验，通过对辣椒穴盘育苗的幼苗素质的观测，探讨污泥-蚓粪基质在辣椒育苗上的应用效果。结果表明，污泥-蚓粪复合基质处理的辣椒幼苗的生物量、地上部分生长、地下部分生长及壮苗指数均优于对照处理。W3处理的辣椒幼苗生物量、根系活力最高，其余依次是W2＞W4＞W1。随污泥、蚓粪比例的提高，辣椒幼苗的株高、SPAD值呈逐渐上升的趋势，茎粗、根系各项形态指标呈先上升后下降的趋势。利用适当配方的污泥-蚓粪基质可明显提高辣椒幼苗的质量，W2、W3、W4处理的辣椒幼苗壮苗指数较高，W1、CK处理的辣椒幼苗壮苗指数较低。

Abstract:

Through feeding earthworms with municipal sewage sludge, the vermicompost was produced. Then four proportions of vermicompost to vermiculite (4:6, 5:5, 6:4, 7:3, namely W1, W2, W3 and W4, respectively) were designed to formulate the growth substrate used in plug nursery bed for capsicum seedling. During seedling development, the growth status and characters of seedling were observed and measured. Results showed that the biomass of both overground and underground parts and seedling index higher in vermicompost substrate than those in a commercial substrate (CK). The biomass and root vigor of capsicum seedlings in W3 treatment was the highest, with the order of W3>W2>W4>W1. With the increase of vermicompost proportion, plant height and SPAD value of the seedlings tended to increase, while stem diameter and root characters increased firstly then decreased, which indicated that the quality of capsicum seedling could be improved by properly formulated substrate with vermicompost derived from municipal sewage sludge. In this study, higher seedling index was observed in W2, W3 and W4 treatments, while that in CK and W1 treatment was lower.
