摘要
以不同春油菜品种为研究对象,采用露地和半膜覆盖穴播种植模式,分别在庆阳市庆城县和正宁县对8个春油菜品种开展了田间试验研究,通过对春油菜生育期、植株特性、产量情况进行统计分析,旨在验证春油菜在该区种植的可行性。结果表明:8个春油菜品种均可以在7月15日左右成熟,播种时间和种植模式与成熟时间无必然相关性;陇油杂1号的平均株高、一次有效分枝、主花序长度均显著高于其他品种,分别达到了150.1 cm、7.5个和52.9 cm,陕油168的平均二次有效分枝最多,为6.9个,沣油306的角果最长,为7.2 cm,秦油558的有效分枝高度最大,为86.3 cm;陇油杂1号和陇油杂2号产量水平最高,分别达到了114.4 kg/667 m^(2)和111.2 kg/667m^(2),适宜于陇东地区种植。
A field experiment was conducted to evaluate the growth characteristics and yield of eight spring rapeseed varieties under two planting patterns—open-field cultivation and semi-film mulching—in Qingcheng County and Zhengning County,Gansu Province.The growth period,plant characteristics and grain yield were analyzed.The results showed that all eight varieties matured around July 15,with no significant correlation between sowing time,planting pattern,and maturity date.Among the varieties,‘Longyouza No.1’exhibited the greatest average plant height(150.1 cm),main effective branches(7.5),and main inflorescence length(52.9 cm),significantly surpassing other varieties.‘Shanyou No.168’had the highest number of secondary effective branches(6.9),while‘Fengyou No.306’produced the longest siliques(7.2 cm).‘Qinyou No.558’had the highest effective branch height(86.3 cm).In terms of yield,‘Longyouza No.1‘and‘Longyouza No.2’had the highest production levels,reaching 114.4 kg/667 m^(2) and 111.2 kg/667 m^(2),respectively,indicating their suitability for cultivation in the Longdong region.
