1982—1984年在张家口、山海关、保定、石家庄、衡水、邢台、邯郸等地,在露地、地膜覆盖和小拱棚等不同栽培条件下,进行了叶面喷施硫酸锌水溶液防治甜椒病毒病的试验,结果简报如下:1.不同浓度硫酸锌的防治效果0.05%、0.1%和0.5%三种浓度都有防病增产作用,其中以0.05%和0.1%浓度效果较好.与对照相比:病株率降低8.8—25.4%,病情指数降低10.6—28.2%;开花期提前6—11天;株高增加6.1—11.8%;门果数增加16.2—62.2%;
From 1982 to 1984, foliar application of zinc sulfate aqueous solution to control pepper virus disease was carried out under different cultivation conditions in Zhangjiakou, Shanhaiguan, Baoding, Shijiazhuang, Hengshui, Xingtai, Handan and other places under open field, mulching and small sheds The results are as follows: 1. The control effect of different concentration of zinc sulfate 0.05%, 0.1% and 0.5% of the three concentrations have the effect of disease prevention and increase production, of which 0.05% and 0.1% concentration effect is better.Compared with the control: Planting rate decreased 8.8-25.4%, the disease index decreased 10.6-28.2%; flowering 6-11 days ahead of schedule; plant height increased 6.1-11.8%; number of door fruit increased 16.2-62.2%;
