摘要
为研究菇渣、蚓粪和蛭石混合基质化处理产物对番茄幼苗的生长影响特征,采用菇渣为原料,在菇渣中加入蚓粪和蛭石,复配成育苗基质。育苗期间测定番茄幼苗的各项生长指标。结果表明,菇渣复配成的育苗基质相较于市售基质可以显著增加番茄幼苗叶片中叶绿素含量。菇渣与蚓粪、蛭石按8:1:1体比混合的育苗基质培育的番茄幼苗在茎粗、根长、根表面积、根体壮苗指数都大于市售基质。菇渣加入蚓粪、蛭石复配基质的各处理的番茄幼苗茎叶鲜重、茎叶干重、总鲜重、总干重和根冠比与市售基质相比差异不显著。总之,菇渣可以作为基质材料培育番茄幼苗,添加蚓粪和蛭石都有利于提高番茄幼苗的壮苗指数。本试验条件下,推荐采用菇渣与蛭石按照(8~4):1体积比复配的基质进行番茄育苗。
The paper aims to study the influences of mushroom residue, vermicompost and vermiculite matrix product on tomato seedling growth. A plug seedling substrate for tomato was developed by using mushroom residue as main raw material, added with different ratios of vermicompost and vermiculite. Then, growth indexes of tomato seedlings were measured during seedling development. The results showed that, compared with the commercial substrate, the matrix of mushroom residue could obviously increase the chlorophyll content of tomato plants. The stem diameter, root length, root surface area, root volume of tomato seedlings cultivated in the substrate with mushroom residue, vermicompost and vermiculite at the volume ratio of 8：1：1 were significantly higher than those in commercial substrate（CK）. Compared with CK, tomato seedlings in mushroom residue mixed with different ratios of vermicompost and vermiculite had no significant differences in stem and leaf fresh weight, shoot dry weight, total fresh weight, total dry weight and root/shoot ratio. In short,mushroom residue can be used as an effective substrate to develop tomato seedlings, and mushroom residue added with vermiculite（8-4）：1 is more conducive to the development and growth of tomato seedlings.
