葡萄裂果病综合防治试验

INTEGRATED TECHNIQUE MAJORING WITH ECOLOGICAL ADJUSTMENT TO CONTROL GRAPE FRUIT SPLIT

为有效防治葡萄裂果病 ,以乍娜和巨峰为材料 ,进行了综合防治试验 ,结果表明 ,采用控制负载量、调整浇灌次数、土施多效唑、适时喷洒多丰农化学药剂等以生态调控为主的综合技术 ,可以使葡萄裂果率降至 10 %～ 12 %以下 ,裂果后的腐烂率降至 7%～ 8%以下 ,有效地控制了葡萄裂果病的发生和危害。

Through the studies from 1994 to 1997, the disease of grape fruit split was effectively controlled with an integrated technique. The integrated technique consists of controlling the grape yield to a moderate scale, adjusing the frequency of irrigation to every five to seven days, applying pp 333 to soil with four or six grams per plant after harvesting, and sprinkling 40% Duofengnong Wettable Powder two times during the period of fruit′s fast growing. The technique was proved to be good also for protecting the disease of grape′s white rot .
