今年上半年,河北林学院有三项科研成果通过省级鉴定。 一、苹果煤污病侵染规律和防治的研究 苹果煤污病在河北及黑龙江、吉林、辽宁、陕西、江苏等省均有不同程度发生。我省太行山区发病尤为严重,有的果园果实被害率高达100％。果实染病后,果皮被一种黑煤状物覆盖,失去固有的颜色和光泽,商品价值大大降低。课题组通过三年的试验研究,摸清了病害的始、盛、末期及病害的发生、传播与小气候的关系,找到了有效的防治方法,使好果率达到97％以上。参加鉴定的专家们认为,此项成果立题正确,方法科学,防治措施简便易行,经济效益显著,适于大面积推广应用,达到了同类研究的国内先进水平。
The first half of this year, Hebei Forestry College has three scientific research achievements through the provincial appraisal. First, the law of apple coal pollution and prevention and control of apple coal pollution in Hebei and Heilongjiang, Jilin, Liaoning, Shaanxi, Jiangsu and other provinces have varying degrees of occurrence. The incidence of Taihang Mountains in our province is particularly serious, some of the orchard fruit damage rate as high as 100%. After the fruit is infected, the peel is covered with a black coal that loses its intrinsic color and luster and greatly reduces the value of the commodity. After three years of experimental research, the research group found out the beginning, end of the disease and disease, the relationship between the spread and the microclimate, and found an effective control method, so that the good fruit rate reached more than 97%. The experts participating in the appraisal believe that the result of this project is correct, scientific method, easy to control measures, significant economic benefits, suitable for large-scale popularization and application, reaching the domestic advanced level of similar research.
