黄河故道地区的金帅苹果的果锈十分严重,有些年份锈果率高达80％以上,严重影响其商品价值。为此,我们于1977～1985年在清江果园进行了金帅,苹果果锈发生规律与防治技术的研究。 试验园为金帅成年树,树龄17～25年,生长正常,株产200斤左右。土壤为沙土,pH8左右,植株的一致性较好。选试验树10株,从花瓣开始脱落到6月30日,每隔7天套袋一次,每次套袋100只,共10次,采收时检查锈果率。同时选试验树3株,定枝调查锈果率。从花谢至发锈期结束,定期取样固定做成石蜡切片,观察果皮的解剖结构及果锈形成的过程。
Golden handsome apple in the old course of the Yellow River fruit rust is very serious, rust rust rate in some years as high as 80%, seriously affecting the value of their goods. To this end, we conducted in 1977 ~ 1985 in the Qingjiang Orchard, Shuangshuai apple rust occurrence and prevention and control technology. Experimental Park for the handsome tree, aged 17 to 25 years, normal growth, yield about 200 pounds. Soil is sandy soil, pH8 or so, plant consistency is better. Select the test tree 10, from the petals began to fall off to June 30, every 7 days bagging time, bagging 100, a total of 10 times, check the rust harvest rate. At the same time, three test trees were selected and the rate of rust fruit rusting was tested. From the flower Xie hair until the end of the rust period, regular sampling made of fixed paraffin sections observed peel anatomical structure and fruit rust formation process.
