蚓粪复合育苗基质对番茄幼苗生长的影响

摘要

以蚓粪、腐熟中药渣、泥炭、蛭石、珍珠岩为原料,将不同原料按照不同比例复配成四种育苗基质。选取市场上销售的育苗基质作为对照（CK）,研究不同比例复配的蚓粪育苗基质对番茄苗期生长的影响。结果表明：基质D培育的番茄幼苗的鲜重、株高、茎粗、根长、根表面积、根体积均优于其它配比的育苗基质,育苗效果显著提高,可推荐作为番茄育苗的专用型有机营养基质。%Taking vermicompost,Chinese herbal medicine residue,peat,vermiculite and pearl stone,as the basic substrates,the author investigates the effects of four kinds of substrate combinations on the growth of tomato,compared with the commercial substrate usually made from chicken feces and peat.The results show that tomato seedlings grow better in all the four homemade seedling substrates than in the commercial substrate.The tomato seedlings cultivated in seedling substrate D grow obviously better than in others.Their biomass,plant height,stem diameter,root length,root surface area and root surface volume increase in substrate D more obviously than in other mixed substrates.Therefore,the seedling substrate D has great effect on the growth of tomato seedlings,which can be recommended as the seedling substrate of tomato.
