| 摘 要： | 在半干旱区对春小麦新品种甘春25号进行了适宜播期试验。结果表明,不同播期对甘春25号春小麦的生长发育、产量及产量构成均有影响。随着播期的推迟,生育期缩短。3月8日至3月15日播种时表现了较强的播期适应性,产量因素较协调,折合产量较高,分别为3 236.05、3 356.22 kg/hm2。经模拟方程,最佳播种时间为3月12日,在适宜播期范围内,会宁旱地条件下春小麦甘春25号的适宜播期为3月上、中旬。

| Abstract: | The effects of different sowing date on agronomic traits, drought resistance, disease resistance, yield components and yield of spring wheat Cultivar Ganchun 25 are studied. The result shows that the growth and development, yield and yield components of Ganchun 25 are affected by different sowing date. The whole growth period decreases with the delay of sowing date. From March 8th to 15th, Ganchun 25 represents stronger adaptability when sowing, and the yield factors are more coordinated, and the yield is higher, which is 3 236.05 kg/hm2 and 3 356.22 kg/hm2. By the simulation equation, the optimum sowing time is March 12, the suitable sowing period of Ganchun 25 is the first and second ten days of May in dryland of Huining in the suitable sowing period range. |
