In the research, major distribution areas of key plants were investigated and statistical work was made on plant species. The results show that aromatic plant species can be classified into over 170 species in 43 families, with 26 key families. In addition, the application of the plant species was il ustrated and some suggestions were proposed as wel .展开更多

The results showed that when the virus diseases in greenhouse tomato were serious, 0.5% Lentinan AS 3 000 ml ＋ GHB WP 600 g and 8% Ningnanmycin AS 900 ml ＋ GHB WP 600 g per hectare were applied 4 times with an interval of 7 days, and the control effects on the 10th, 17th, 26th and 35th day were above 88%, 87%, 78% and 67%, respectively. The difference in control effect of the two biological pesticides was insignificant, while their control effects were all significantly better than that of moroxydine hydrochloride （CK） ＋ GHB. The obtained results indicated that Lentinan ＋ GHB and Ningnanmycin ＋ GHB were the ideal biological pesticides, which could be used not only for controlling tomato virus diseases, but also for realizing modern, pollution-free, green and organic agricultural production.展开更多
