摘要
用田间试验和定量分析的方法研究普那菊苣高产与主要栽培因子之间的数量关系,建立有关数学模型并作了增产效应分析。在试验条件下,普那菊苣产量要达到83390.38kg/ha,种植密度应为64253窝/ha,配施N肥为331.05kg/ha,K肥为58.8kg/ha,P肥为256.05kg/a,达到普那菊苣高产目的。
It was studied that the quantitative relation between high yield and main cultivation factor by using field trial and quantitative analysis, established relative mathematics model and made increased effect analysis. The yield of puna chicory can reach 83390.41kg per hectare, under the trial condition which planting density is 64253 cave per hectare, fertilizing nitrogenous fertilizer quantity is 331.05kg per acre and potassium quantity is 58.8kg per hectare and phosphate fertilizer quantity is 256.05kg per hectare. So the objective of puna chicory high yield was realized.
