堆制番茄秸秆浸提液对黄瓜和大白菜的化感作用
Allelopathic effects of anaqueous extract from composted tomato residues on the growth of cucumber and Chinese cabbage
摘要
Abstract
To understand the allelopathic effects of composted tomato residues on cucumber and Chinese cab-bage vegetables, five concentrations (10.0, 20.0, 30.0, 40.0, and 50.0 g·L-1) of extracts from composted tomato residues and a control (ck) (0.0 g·L-1)were applied to germinating seeds and seedlings during growth and then employed seed germination bioassay method to measure the germination rate, germination rate, seedling length, and fresh weight of cucumber and Chinese cabbage and finally evaluated. Results showed that the germination rate, seedling length, and fresh weight of cucumber and Chinese cabbage were promoted at low aqueous extract concentrations (10.0-20.0 g·L-1). Also, the germination rate and germination index of cucumber and Chinese cabbage as well as the seedling length and fresh weight of cucumber were inhibited at a high concentration (>40.0 g·L-1). Root growth of cucumber and Chinese cabbage for all concentrations was inhibited. Also, the root length of cucumber treated with extracts was significantly lower (P<0.05) than ck. Overall, the extracts from composted tomato residues showed some inhibitory effect on cucumber seedling growth and a certain role in promoting on the growth of Chinese cabbage seedlings, but both of them did not reach the significant level. Thus, to a certain extent, the tomato residues could alleviate its inhibition effect after composting.关键词
