防治病虫害:银花产量历年不能提高的主要原因,是蚜虫为害。为了消灭虫害,必须在孵化期喷射二百倍的6%可湿性666,到四月底五月初,蚜虫大量发生时期再喷射一遍八千倍的1605,前后共喷药三遍,这样就基本上可以控制蚜虫为害,增产20%。培土松土:秋末冬耕应普遍进行一次培土,在春季解冻后,还应结合顶凌耙地,进行一次中耕松土。及时进行培土和中耕松土,不仅能促使银花的生长,同时也
Prevention and control of pests and diseases: The main reason why silver yield cannot be increased over the years is due to locust infestation. In order to eradicate pests, it is necessary to inject 200-fold 6% wettability during the incubation period. By the end of April and early May, when a large number of locusts occur, they will inject 8,000 times more 1605 times. Before and after spraying three times, they basically can Control locust damage, increase production by 20%. Soil cultivating soil: In the late autumn and winter ploughing, soil should be commonly cultivated. After thawing in the spring, a cultivator soil should be used in conjunction with the top soil. Timely soil cultivation and cultivating loose soil can not only promote the growth of silver flower, but also
