蚯蚓粪育苗基质在茄子育苗中的应用研究

目的]研究蚯蚓粪基质在茄子(Solanum melongena L.)育苗中的应用效果,为开发利用蚯蚓粪作为穴盘育苗基质提供理论依据。方法]选用10种自制配方蚯蚓粪基质T0(蚓粪+蛭石+N2+P+K)、T1(蚓粪)、T2(蚓粪+N1)、T3(蚓粪+P+K)、T4(蚓粪+N1+P+K)、T5(蚓粪+N2+P+K)、T6(蚓粪+蛭石)、T7(蚓粪+蛭石+N1)、T8(蚓粪+蛭石+P+K)、T9(蚓粪+蛭石+N1+P+K)为处理,以市售有机活性基质为对照(CK),研究了不同配方蚯蚓粪基质在茄子育苗期间对幼苗株高、茎粗、开展度、叶绿素含量、叶片数、地上与地下部鲜、干重等性状和生长发育的影响。结果]T0蚯蚓粪基质配方效果最佳,幼苗质量好,生长健壮,且与其他基质配方相比差异达显著水平,是较理想的茄子育苗基质。结论]该研究可为蚓粪基质穴盘育苗进行产业化开发和利用提供部分理论依据,同时为促进蔬菜的大规模生产和工厂化育苗产生积极作用以获得更大的社会和经济效益。

Study on Application of Vermicompost in Eggplant(Solanum melongena L.) Plug Seedlings

Objective] The purpose was to study the application effects of vermicompost in eggplant plug seedlings,and provide a theoretical basis for developing and utilizing vermicompost as plug seedling matrix.Method] Ten different vermicompost substrates prepared from homemade recipe,including T0(vermicompost+vermiculite+N2+P+K),T1(vermicompost),T2(vermicompost+N1),T3(vermicompost+P+K),T4(vermicompost+N1+P+K),T5(vermicompost+N2+P+K),T6(vermicompost+vermiculite),T7(vermicompost+vermiculite+N1),T8(vermicompost+vermiculite+P+K),T9(vermicompost+vermiculite+N1+P+K),were selected as the plug substrates together with the organic activated substrate CK produced by Huaiying Vegetable Research Institution as control,and the effects of vermicompost on the height of the plant,the stem diameter,the expansion degree,the content of chlorophyll,the leaf numbers as well as the fresh(dry) weight of the plant above(under) the ground,were studied.Result] The results showed that T0 was the ideal substrate with the best performance on plants quality and growth and had significant differences compared with the others.Conclusion] The study provides a theoretic basis for industrialization of taking vermicompost as substrate,also make a positive effect on promoting mass production and industrialized seedlings of vegetables in order to reach great social and economic achievements.
