寒地春小麦晚播技术,可以躲过春季干旱对小麦造成的严重影响。为了探讨寒地春小麦晚播最佳播期和最合理密度,选择当地主栽小麦品种,确定3个播期、3个密度,进行对比试验。试验结果表明,春小麦晚播时间和不同密度对产量的影响明显。
Spring wheat late-sowing technology in cold weather can avoid the serious impact of spring drought on wheat. In order to investigate the best sowing date and the most reasonable density of late spring sowing in cold region, three kinds of sowing date and three densities were selected by contrasting the selected varieties. The results showed that the effects of late sowing time and different density of spring wheat on yield were obvious.
