药渣蚓粪对番茄幼苗生长发育的影响

Effect of Earthworm-processed Chinese Herbal Medicine Residues on the Growth and Development of Seedlings of Tomato

以番茄为试材,研究了添加药渣蚓粪对番茄穴盘苗生长发育的影响。结果表明:添加蚓粪处理的出苗率均高于对照处理,并以10%蚓粪+90%草炭处理出苗率最高。二叶一心期时,添加蚓粪处理的幼苗株高、茎粗、全株干重和壮苗指数均显著高于对照处理;四叶一心期时,添加蚓粪处理的幼苗叶绿素a、叶绿素b、叶绿素总量和根系活力均显著高于对照处理,并以10%蚓粪+90%草炭处理的效果最好。

The experiment of adding earthworm-processed Chinese herbal medicine residues to the basic substrate was carried out in order to study the effects of different amounts of earthworm-cast on the growth and development of plug seedlings of tomato in order to provide theory for making substrates. The results showed that the germination rate of adding earthwornrcast was higher than CK, with the 10% earthworm-cast＋ 90% peat having the highest germination rate. At the two-true-leaf stage,compared with control,the height,stem diameter,dry weight of plant,seedling health index had significant increased respectively. At the four-true-leaf stage, the chlorophyll a, chlorophyll b, chlorophyll a＋ b and root activity of adding worm-cast had significant higher respectively, the optimum ratio was 10% worm-cast compound substrates.
