甜椒是广大居民喜食的一种蔬菜,也是夏秋季上市的主要蔬菜种类之一。然而,甜椒病毒病给甜椒生产带来很大障碍,我们于1989~1991年连续3年进行了叶面喷锌防治甜椒病毒病的应用研究,取得了比较明显的防治效果,并且提高了单产和经济效益。 3年的试验证明,用0.05%硫酸锌(ZnSO_4·7H_2O含锌99%)在甜椒整个生育期的苗期、定植缓苗后期、盛果前期、盛果后期分四次进行叶面喷施,不仅可以提高甜椒前期及总产量,还可以推迟病毒病的始发
Bell peppers are a vegetable that most residents like to eat and are also one of the main types of vegetables that are marketed in summer and autumn. However, the pepper pepper virus disease caused a great obstacle to the production of sweet pepper. From 1989 to 1991, we carried out the application research on the prevention and control of pepper virus disease by foliar zinc spraying for three consecutive years, and achieved obvious control effect and increased Yield and economic benefits. Three years of experiments show that 0.05% zinc sulfate (ZnSO 4 · 7H 2 O containing 99% of zinc) in sweet pepper throughout the growth of the seedling stage, the late planting Huanmiao, Sheng early fruit, fruit full bloom in four post-foliar spray , Can not only improve the pre-bell pepper and total output, but also can delay the onset of viral disease
