核桃青皮不同浸提方式对辣椒和番茄的化感作用研究

Study on Allelopathy of Different Extraction Methods of Walnut Green Husk on Chili and Tomato

研究了不同浓度核桃青皮冷水浸提液、热水浸提液对辣椒及番茄幼苗生长作用的影响。研究表明,两种浸提液对辣椒及番茄的种子萌发率都有明显的抑制作用,对幼苗高及根长有低促高抑作用,作用强度随着浓度增大而增大,且抑制作用是热水浸提液>冷水浸提液。

The effects of different concentrations of cold and hot water extracts of walnut green husk on the growth of chili and tomato seedlings were studied.The results showed that the two kinds of extracts significantly inhibited the germination rate of chili and tomato seeds.It had a promotion at low concentration and inhibition at high concentration on seedling height and root length,and the intensity of inhibition increased with the increase of concentration,and the inhibitory effect of hot water extract was bigger than that of cold water extract.
