摘要
以蚯蚓粪为育苗基质,通过与草炭、蛭石传统育苗基质比较,研究蚯蚓粪在工厂化育苗上应用的可行性。结果表明:纯蚓粪(1:0)处理的番茄出苗率、株高、茎粗、干重、壮苗指数、叶绿素含量与传统育苗基质(CK)无差异。相对于CK,蚓粪与蛭石混合基质促进番茄幼苗的生长,但其作用效果与基质混合比例有很大关系。该试验中蚯蚓粪和蛭石以2:1(V:V)比例混合基质育苗效果最佳。
Taking wormcast as cultural substrate of tomato plug seedlings,compared with traditional cultural substrate composed with peat and vermiculite,the feasibility of wormcast application in industrialized breeding were studied.The results showed that there were no marked differences on germination rate,height,stem diameter,dry weight,seedling quality index,SPAD value with treatment of 1：0 and CK.Compared with CK,wormcast mixed with vermiculite promoted the growth of tomato.The appropriate ratio of wormcast to vermiculite was 2：1（V：V）.
