摘　　要：以冬小麦品种"藏冬25"为试验材料,研究在不同生育期喷施"黑汁"对冬小麦产量及产量构成因素变化的影响。结果表明:喷施"黑汁"对冬小麦穗粒数影响并不明显,千粒重、穗数和产量随着喷施次数的增加,总体表现上升的趋势。苗期喷施"黑汁"可有效增加冬小麦穗数,在返青期和抽穗期喷施"黑汁"对提高冬小麦千粒重效果比较明显。对冬小麦产量影响相关性大小依次为:穗数>千粒重>穗粒数,穗数与产量之间表现为极显著正相关。The present study used the winter wheat variety‘Tibetan winter 25’as the test material,and the effect of‘black juice’study on the yield and composition factors of winter wheat was studied by spraying‘black juice’during different growth periods. The results showed that the effect of‘black juice’on spike grain number of winter wheat was not obvious. The effect of‘black juice’on increasing the number of ears of winter wheat was obvious in the seedling stage,and the effect of‘black juice’on the increase of the grain weight of winter wheat was obvious. The correlation of the influence of winter wheat yield was on the number of 〉 1000-grain 〉 panicle,and the number of ear number was positively correlated with the yield per mu.
