摘　　要：采用3因素(氮、磷、钾)3水平的正交施肥试验研究不同氮磷钾配比施肥对软枣猕猴桃扦插育苗生长的影响,为筛选扦插育苗合理施肥方案提供依据。结果表明:氮磷钾配比施肥对软枣猕猴桃扦插生根率、根系生长和新枝生长均有明显地促进作用,各施肥处理在生根率、根长、根粗、根数、新枝长、新枝粗、芽眼数等生长指标间均存在显著性差异。以氮磷钾配比量为氮7 g/m、磷7 g/m、钾14 g/m时,生根率最大,高达78.91%;根系发育最好,根长41.6 cm、根粗3.53 mm、根数约为25个;新枝生长较旺,新枝长77.40 cm、新枝粗6.93 mm、芽眼数约7个;对软枣猕猴桃扦插育苗的促进效应最大,为最优施肥处理。This article adopts an orthogonal fertilization experiment with three factors(nitrogen,phosphorus,potassium)and three levels to study the effect of different nitrogen,phosphorus,and potassium fertilization ratios on the growth of A.arguta cutting seedlings,providing a basis for selecting a reasonable fertilization plan for cutting seedlings.The results showed that the nitrogen phosphorus potassium ratio fertilization had a significant promoting effect on the rooting rate,root growth,and new branch growth of cuttings.There were significant differences in growth indicators such as rooting rate,root length,root thickness,root number,new branch length,new branch diameter,and bud number among different fertilization treatments.When the ratio of nitrogen,phosphorus,and potassium was 7 g/m of nitrogen,7 g/m of phosphorus,and 14 g/m of potassium,the rooting rate was the highest,reaching 78.91%;The root system had the best development,with a root length of 41.6 cm,a root thickness of 3.53 mm,and approximately 25 roots;The new branches grow vigorously,with a length of 77.40 cm,a thickness of 6.93 mm,and about 7 buds;The promotion effect on the cutting and seedling cultivation of A.arguta was the greatest,and it was the optimal fertilization treatment.
