摘　　要：为提高穴盘苗质量和经济效益,研究叶面喷施不同浓度粉锈宁对番茄、黄瓜穴盘苗的矮化影响、壮苗效果及产量效益。结果表明:粉锈宁的使用会使植株矮、壮,根系发达,根冠比增大,增加植株鲜重、干重,抗逆能力增强,提高结实率,增加产量有显著的效果。当浓度300mg/L时,秧苗的矮化特征表现最佳,有效的控制了黄瓜、番茄幼苗的高度,提高穴盘苗的素质,但当浓度600mg/L时,叶片严重皱缩、扭曲、黄化,不能进行正常的光合作用,不能为穴盘苗的正常生长提供能量来源,秧苗质量下降。In order to improve the quality and economic benefits of plug seedlings,the effects of leaf spraying different concentrations of Triadimefon on tomato and cucumber plug seedlings were studied.The results showed that the use of Triadimefon could make the plant shorter and stronger,the root system developed,the ratio of root to shoot increased,the fresh weight and dry weight of the plant increased,the ability of resistance to adversity increased,the rate of seed set increased,and the yield increased.When the concentration was 300mg/l,the dwarfing characteristics of seedlings were the best,the height of cucumber and tomato seedlings was effectively controlled,and the quality of plug seedlings was improved,but when the concentration was 600mg/l,the leaves were seriously wrinkled,twisted and yellowed,can Not carry on the normal photosynthesis,can not provide the energy source for the plug seedling’s normal growth,the seedling quality drops.
