摘要
为解决吐鲁番地区黄瓜工厂化育苗过程中易徒长问题,采用不同浓度多效唑药液对黄瓜幼苗不同生长时期进行喷叶处理。结果表明:PP333处理能够有效的解决黄瓜穴盘育苗中的徒长问题,促进根系的发育,提高壮苗指数,但使用的适宜时期和适宜浓度不同,使用时间比较严格,推迟或提早都会影响黄瓜秧苗质量,PP333喷施叶面处理适宜在黄瓜出苗后15d左右即子叶平展期,最宜浓度为100mg·L-1。
Cucumber seedling nursery in Turpan area prone to leggy seedlings,in order to solve this problem,different concentrations of liquid MET in different growth stages of cucumber seedlings foliar spray treatment were studied.The results showed that PP333 treatment could effectively solve the cucumber seedling cultivation leggy problems and promote root development,improve seedling index,but using the appropriate time and the appropriate concentrations of the different,more stringent time,delayed or early would affect the cucumber seedling quality,PP333 spraying foliar treatment was suitable for about 15 dafter emergence namely cucumber cotyledons flat extension,the most appropriate concentration was 100mg·L^-1.
