银川地区葡萄黄化病综合防治技术

Technology for Integrated Control of Chlorosis of Grapevine in Yinchuan Area

文章全面分析了葡萄黄化病产生的原因,并提出:施用复合铁矫正剂(硫酸亚铁0.5%+0.1%柠檬酸+0.3%尿素)比单纯施用硫酸亚铁防治效果好;同时,要通过增施有机肥、提高树体综合管理水平、合理定产等措施才能有效防治黄化病。

The cause of chlorosis on grapevine is analyzed. It is put forward that the effect of applying composite iron cor-rection agent （0.5% FeSO4＋0.1% citrate＋0.3% urea） was much better than that of applying FeSO4 only. The chlorosis of grapevine can only be controlled effectively by the measures of increasing application of organic fertilizer, improving the comprehensive management level of the tree body and limiting the yield on a rational level.
