摘要
2009—2010年在宁海县开展小麦品种和主要栽培因子,包括种植密度、播种时期及氮肥用量对小麦赤霉病为害的影响试验。结果表明:所选取的10个小麦品种(系)对赤霉病存在显著抗性差异,其中‘宁71737’病情指数最低,抗性表现最好。以‘扬麦12’为材料的栽培因子试验结果显示,2009—2010年生长季小麦赤霉病的发生程度,11月上、中旬播种的小麦赤霉病为害程度显著高于其他播种处理;而播种量和氮肥施用量对赤霉病为害影响没有显著差异。
Effects of varieties and major cultivation factors,including plant density,seeding time and amount of nitrogen fertilizer,on the wheat scab in Ninghai county of Zhejiang Province during 2009 to 2010 were studied.The results showed that ten selected wheat varieties showed significant difference in resistance to wheat scab,and the variety Ning71737 had the lowest disease index and the highest resistance level.With Yangmai 12 as research material,the wheat seeded in early and middle November in 2009 were most susceptible to wheat scab,the percentage of scab spikes and disease index were significantly higher than others.And there were no marked difference among different treatments of seeding quantity and amount of nitrogen fertilizer,respectively.
