摘要
为促进优质小麦新品种的推广,以优质抗倒伏小麦新品种克春19为材料,在优质强筋小麦最优施肥水平基础上,研究适合该品种的最佳播种时期和播种密度。结果表明:优质抗倒伏小麦品种克春19在克山及相似生态区播种时期3月30日,密度700万株·hm-2处理下产量水平与其他处理差异显著,表明克春19在克山及相似生态区适宜顶凌早播,适当密植可以获得较高产量。
In order to promote the popularization of high quality wheat varieties,Kechun 19 with high quality and strong lodging resistance was used as the material in this experiment,on the basis of the optimum fertilization level of high quality and strong gluten wheat,the optimum sowing time and sowing density were studied.The results showed that the yield level of Kechun 19 was significantly different from the other treatments under the condition of sowing time on March 30th and density 7 million plants per hectare in Keshan and similar ecological areas,which indicated that Kechun 19 was suitable for early sowing,and higher yield could be obtained by proper close planting.
