随着城乡居民生活水平的改善,人们对鲜食葡萄质量的要求也在提高。近年来,由于鲜食葡萄栽植面积不断扩大,病虫害的发生率也趋于严重,果农为了控制病虫害,增加喷药的次数和用量,从而使果粒污染物严重,果粒极不洁净,食用时难以洗净,致使商品价值降低。采用套袋技术是解决这一问题的有效途径。我县曹柳河村部分葡萄种植户于96～97两年进行了套袋试验,结果是套袋葡萄的果穗发病率为1％,果穗无污染。而未套袋葡萄
With the improvement of living standards of urban and rural residents, the quality of fresh grape is also increasing. In recent years, due to the growing area of fresh grape planting, the incidence of pests and diseases also tends to be serious. In order to control pests and diseases, farmers increase the number and dosage of spraying, so that the fruit particles are seriously contaminated and the grains are extremely unclean. Hard to wash, resulting in lower value of the goods. The use of bagging technology is an effective way to solve this problem. Some of the grape growers in Cao Liuhe Village in our county carried out bagging tests in 96-97 years. As a result, the incidence of earring of bagged grapes was 1%, and the ears were non-polluting. Not bagging grapes
