基于正交试验的花生种养结合栽培方式研究

种养结合是农业循环经济发展的重要措施之一。通过正交试验设计,分析了不同种植密度、复合肥用量、腐熟干粪用量对花生生长发育及产量的影响。分析结果表明:1)三因素中高钾复合肥用量对花生的生长发育及产量影响最大。2)13-10-20高钾复合肥用量为300kg/hm2的处理组合普遍表现出植株较高、分枝数较多、单株结果数多等特点。3)产量分析结果显示:最优处理组合为种植密度120 000穴/hm2、高钾复合肥300kg/hm2、腐熟干粪30kg/hm2,同时影响产量大小的因素顺序为:高钾复合肥腐熟干粪种植密度。

The Combination of Planting and Cultivating Peanut Based on Orthogonal Experiment

The combination of planting and cultivation is one of important measures for develo-ping agricultural recycling economy.Based on orthogonal experimental design,the paper ex-plores the effect of different planting density,fertilizer dosage and the dosage of dry manure composting on the growth and yield of peanut.The results show that 1）the amount of potassi-um fertilizer has the greatest impact on the growth and yield of peanut.2）The treatment about 13-10-20 potassium fertilizer dosage of 300 kg/hectare generally shows higher plants,more branches per plant,more pod numbers per plant and so on.3 ）Yield analysis shows that the most optimal treatment is planting density of 120 000 points/hectare,high potassium fertilizer 300 kg/hectare and dry manure composting 30 kg/hectare,while the order of the factors af-fecting the yield is arranged as potassium fertilizer〉dry manure composting〉planting density.
