葡萄套袋栽培对比试验

针对当前我区种植葡萄由于雨水多、气温偏高,中后期病虫危害严重的特点。采用葡萄套袋和不套袋栽培的对比试验,得出葡萄套袋栽培比对照增产42.4~90.6%,每667m2经济效益增加2694元~6330元。葡萄套袋栽培具有明显改善果实品质,防止病虫害,减少农药残留,改善果实风味,并且具有操作方便、低投入高效益的特点,适合在我区大面积推广。

Comparative Experiment on Grape PB- Cultivating Technique

According to the feature of Guangxi climate with high temperature and the characteristics of occurrence of inset pests in the mid-late-term period of growth of grape in Guangxi,a comparative trial on adoption of grape PB cultivating technique and non-grape PB cultivating technique was conducted.The experiment result showed that the adoption of grape PB cultivating technique could result in better economic effect on grape output from RMB 2694 yuan to 6330 yuan,increasing by 90.6% from the previous 42.4%.Additionally,the adoption of grape PB cultivating technique could also brought about obvious effect in terms of improvement of fruit quality,prevention and control of pests,decrease of residues of chemical pesticide and improvement of fruit flavor,so it is very suitable to extend the technique in large scale in Guangxi due to the characteristics of convenience in operation and low input in cost.
