摘要
为明确银川地区葡萄出现黄化现象的原因,通过对喷施不同铁制剂矫正效果的比较,筛选出理想的铁配方用于葡萄缺铁黄化病防治。以银川地区缺铁黄化的葡萄园为研究对象,采用土壤诊断和叶片诊断等方法确定黄化的原因,并以单纯喷施硫酸亚铁为对照,喷施不同铁制剂进行矫治,检测其对葡萄叶片叶绿素的影响。分析认为:银川地区葡萄黄化原因主要是由于土壤pH偏高,结果表明:不同铁配方对葡萄黄化的矫治效果不同,其中处理1(硫酸亚铁0.5%+柠檬酸0.1%+尿素0.3%)的效果最好,显著提高了葡萄叶片的叶绿素含量。
This study was conducted to find the reasons for chlorosis of grape in Yinchuan and select better iron preparations for remedying it. Soil and plant diagnosis and spraying diagnosis were used onto the grapevine trees in some orchards within Yinchuan area. The remedy effects of different iron preparations were compared by determining the content of chlorophyll and available iron of grapevine leaves. The results showed that the reason for grapevine chlorosis was high PH of soil. The effects of various iron preparations were significantly different. The effect of 0.5% FeSO4 + 0.1% citrate + 0.3% urea was the best, which significantly increased the content of chlorophyll.
