摘要
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。
The cultivation pattern of seedlings transplanting of Qianyou 29 with high yield and quality was studied by using the quadric saturation and D-optimum experiment design to speed up extension and application of new rape varieties and raise the comprehensive production level of new rape varieties by a set of cultivation techniques.The results showed that increasing transplant density helped to improve yield of Qianyou 29 and the yield presented the first rise and then decline trend with the increase of N,P and K application amount.The interaction between calcium superphosphate and potassium chloride had the maximum effect on yield of Qianyou 29.The yield of Qianyou 29 could reach 280 kg/667m2 under the cultivation conditions of 9 000 plants/667m2,40 kg/667m2 urea,70 kg/667m2 calcium superphosphate and 30 kg/667m2 potassium chloride.
