摘要
为合理制定玉米-花生间作的施肥及养分调控方案,采用随机区组设计,设置玉米与花生的行比、玉米带与花生带的间距2个处理因素,研究了不同间作模式下花期玉米、花生氮磷钾分配的特点及氮磷钾分配对作物产量的影响。结果表明,玉米的吸氮量、吸磷量在行比为2∶10或2∶2,带间距为50 cm时,达到最高水平;花生的氮、磷、钾吸收量在行比为2∶8,带间距为50 cm时达到最高,营养分配达到较好水平。
The randomized block design was used to study N,P and K distribution characteristics in maize and peanut plants and the effect of their distribution on yield of maize and peanut under the different intercropping pattern of maize and peanut for rationally formulating the application and nutrient adjustment program for maize and peanut intercropping model.The results showed that the N and P absorption of maize reached the highest level when the row ratio between maize and peanut was 2∶10 or 2∶2 and the spacing distance was 50 cm,and the N,P and K absorption of peanut reached the highest when the row ratio between maize and peanut was 2∶8 and the spacing distance was 50 cm.
