长春晚播冬小麦越冬性和产量的初步研究

The Primary Study on Overwintering and Yield of [HT4”H]Late Sowing Winter Wheat in Changchun

将冬小麦品种加 6 90以 4种密度处理 (6 75万株 /hm2 、5 2 5万株 /hm2 、375万株 /hm2 、375万株 /hm2 +抗寒剂 )于 1997年 9月 2 9日种植在长春。结果表明 :在长春晚播冬小麦时 ,不同密度间的生育期和越冬率相似 ;密度增加到 6 75万株 /hm2 和 5 2 5万株 /hm2

Winter wheat (Jia 690) was planted at densities of 675, 525,375 plants/m 2 in Changchun on September 29, 1997 The results showed that when sown at the end of September, the phenology and winter passing rate of winter wheat at different densities were similar The yield of winter wheat at densities of 675 and 525 plants/m 2 were higher than that at the density of 375 plants/m 2
