摘要:
为探究富平辣椒产区适宜的水溶肥追施量，以当地农户常规用量为对照，在辣椒的生长前期、结椒期和盛椒期分别设计了氮、钾肥的减量处理。结果表明：不同阶段的减肥处理辣椒产量和采收数都高于常规追肥量。产量以辣椒生长后期减氮、减钾30%的处理（C3）最高，采收数以辣椒移栽至开花期减氮30%的处理（C2）最高；肥料农学效率以C3处理最高，肥料偏生产力表现为C3和各阶段都减肥30%的C4处理较高。结合土壤基础状况，建议在辣椒生长前期应稳施氮肥，在结椒至盛椒期应少施钾肥。
Abstract:
In order to explore suitable dressing ratio of water-soluble fertilizer in Fuping pepper producing area,this experiment set different chemical N and K water-soluble fertilizer treatments in the early growth,fruiting and full fruiting stage of pepper,and the local normal topdressing rate was chosen as control.The results showed that pepper yield and picking quantity in all fertilizer reduction treatments were higher than the control treatment.The yield of treatment with 30% nitrogen and 30% potassium fertilizer reduction applied at pepper late growth stage(C3) was the highest.Picking quantity of treatment with 30% nitrogen reduction applied at planting to flowering stage(C2)was highest.Fertilizer agronomic efficiency of C3 treatment was the highest and fertilizer partial productivities were higher in C3 and C4 treatment.Combined soil basic condition,we suggested that nitrogen fertilizer should be stable applied in pepper early stage,and potassium fertilizer should be less applied from pepper fruiting to full fruit stage.
