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 83 390kg/hm2,种植密度应为 64 253窝 /hm2,配施N肥为 331kg/hm2,K肥为 59kg/hm2,P肥为 256kg/hm2。
The quantitative relation between high yield and main cultivation factor was conducted by using field (experiment) and quantitative analysis for establishing relative mathematical model, and the effect for raising yield was analyzed. The yield of Puna Chicory reaches 83390 kg/ha, under the trial conditions with 64253 clump/ha of planting density, 331 kg/ha of nitrogen (fertilizer) and 59 kg/ha of potassium fertilizer and 256 kg/ha of phosphate fertilizer.
