摘要
以鲁西地区推广种植面积较大的济麦22、鲁原502、州元9369为研究对象,分析了春季冻害条件下,浇水(冻害发生以前)、追施尿素对品种产量及其构成性状的影响。结果表明:浇水、施肥及其组合处理均能显著地提高供试品种的产量,其主要原因是能显著提高有效穗数,其次是提高了穗粒数,而对千粒重的影响不大;追施尿素对产量的增加作用强于浇水。
In this study as the research object of three wheat combinations, which were Jimai 22, Luyuan 502 and Zhouyuan 9369, and their cultivated area was larger in Luxi area. Meanwhile, we analyzed the cold condition, the effect of variety yield and its components in spring water and topdressing urea. The results showed that the water, fertilizer and their combination can significantly improve the production of varieties tested, the main reason was to improve the effective panicles, the second was to improve the ear grain number, and little influence on grain.
