Abstract:To explore the Sabina chinensis allelopathy, Petri dish filter paper method was used to study the effects of leaf extracts of S. chinensis on the germination and growth of 5 kinds of weed seeds (Kochia scoparia, Echinochloa Crusgalli, Chenopodium album, Amaranthus retroflexus, and Portulaca oleracea) and four kinds of crops (Helianthus annuus, Avena sativa, Brassica campestris, and Fagopyrum Esculentum). S. chinensis leaf, branch and bark were selected to prepare powder and extract for pot experiment. The results showed that S. chinensis leaf extract has significant inhibitory effect on 5 kinds of weed germination and growth. Moreover, the response index (RI) to the germination and growth of K. scoparia, C. album and A. retroflexus was more than -0.98. In the pot experiments, different parts of S. chinensis had better inhibitory effects on seed germination of 5 kinds of weeds and plant height of E. crusgalli and A. retroflexus, the allelopathic intensity of leaves was higher than that of bark and branches, and the effect of soil mixed with leaves was better than that of foliar spraying with extract. The results of allelopathic effect on crops showed that the leaf extract of S. chinensis inhibited the germination of F. esculentum seeds when it was diluted by 1.5 times, but did not affect the plant height and root growth. The seed germination of A. sativa was not affected, but plant height and root length were inhibited. The germination potential and germination index of B. campestris were inhibited, the seed germination rate was not affected, and the plant height and root length growth were promoted. The seed germination and growth of H. annuus were not affected. In all, S. chinensis had good herbicidal activity but little effect on crops at a certain concentration.
