夏秋季节高温多雨,病虫害发生较重,给育苗工作带来很大困难。笔者根据多年实践,认为夏秋季节育苗需掌握以下技术要点。一、选择抗逆性强的品种如番茄作为秋延迟栽培,最好选用中杂9号。该品种经肥城市农业高新技术示范园试验示范,其抗病毒病能力明显优于其他品种,最适合秋延迟栽培,产量品质俱佳。二、做好播前种子处理为了消灭种子表面部分病菌,可用温汤浸种法,即将蔬菜种子放入55℃水中烫种10～15min(分钟),并不断搅拌,至水温自然降至30℃左右时再浸种,也可用40%福尔马林100倍液浸种15～20min或高锰酸
Hot and rainy summer and autumn, pests and diseases occur heavier, bring great difficulty to nursery work. According to many years of practice, I believe that the summer and autumn seedlings need to master the following technical points. First, select the strong resistance varieties such as autumn as late cultivation of tomatoes, the best selection of miscellaneous 9. The variety of demonstration by the Agricultural High-tech Park in Feicheng pilot demonstration, its ability to antiviral significantly better than other varieties, the most suitable late autumn cultivation, yield and quality are superb. Second, do a good job before sowing seed treatment In order to eliminate some of the surface of the germ bacteria can be soaked with warm soup, the vegetable seeds into the 55 ℃ hot water 10 ~ 15min (minutes), and continue stirring until the water temperature dropped to about 30 ℃ Then soaking, but also can be 40% formalin 100 times soaking 15 ~ 20min or permanganate
