为加快油菜新品种的推广应用,实现良种良法配套,提高品种综合生产水平,采用二次饱和D-最优试验设计,对高产优质杂交油菜黔油29号育苗移栽的栽培模式(移栽密度及尿素、过磷酸钙、氯化钾施用量)进行了研究。结果表明:增加移栽密度有利于提高产量,随着氮、磷、钾施用量的增加,产量呈先升后降的趋势,其中以过磷酸钙与氯化钾之间的交互作用对产量的影响最大;当移栽密度在9 000株/667m2,施用尿素40kg/667m2、过磷酸钙70kg/667m2、氯化钾30kg/667m2左右时,黔油29号的产量达280kg/667m2左右。
In order to speed up the popularization and application of new varieties of rapeseed, to achieve a good variety of good methods to improve the comprehensive production of varieties, using the second-saturation D-optimal experimental design, high yield and good quality hybrid rapeseed oil Qiangyou 29 seedling transplanting cultivation mode And urea, superphosphate, potassium chloride application rate) were studied. The results showed that increasing the transplanting density was beneficial to increase the yield. With the increase of nitrogen, phosphorus and potassium application, the yield increased first and then decreased. Among them, the interaction between superphosphate and potassium chloride affected the yield The effect was the greatest. When the transplanting density was 9 000 plants / 667m2, applying urea 40kg / 667m2, superphosphate 70kg / 667m2, potassium chloride 30kg / 667m2 or so, the yield of Qianyou 29 was about 280kg / 667m2.
