摘　　要：为了加速推广利用漯麦163,2018^(-2)019年度研究了不同播期(10月10日、10月17日、10月24日、10月31日)、不同播量(75 kg·hm^(-2)、105 kg·hm^(-2)、135k g·hm^(-2)、165 kg·hm^(-2)、195 kg·hm^(-2))对小麦产量及构成因素的影响。试验结果表明播期间差异不显著,播量间差异达极显著水平。通过对产量构成因素变异性及相关性分析,穗粒数变化最大,千粒重最小,穗粒数与亩穗数和千粒重均呈负相关。因此,通过稳定穗粒数,协调好其与亩穗数和千粒重的关系,使小麦产量三要素相互促进、协调发展,最终达到提高小麦产量的目的。本区域生态条件下以10月17^(-2)4日左右为最佳播期,适宜播量为135 kg·hm^(-2)左右。In order to accelerate the popularization and utilization of‘Luomai 163’,the effects of different sowing dates(October 10,October 17,October 24,October 31),different sowing amounts(75 kg·hm^(-2),105 kg·hm^(-2),135 kg·hm^(-2),165 kg·hm^(-2),195 kg·hm^(-2))on wheat yield and its components were studied.The results showed that there was no significant difference during sowing,and the difference of sowing amount reached a very significant level.Through the analysis of the variability and correlation of yield components,it was found that the number of grains per ear changed most and the weight per thousand grain was the least.Therefore,increasing the number of grains per ear and coordinating the relationship with the effective ear and 1000 grain weight,the three factors of wheat yield can promote and coordinate each other,and finally achieve the goal of increasing wheat yield.Under the ecological conditions of this region,the best sowing date is October 17-24,and the suitable sowing amount is about 135 kg·hm^(-2).
