摘要
探讨了正交试验法在辽西地区山杏林地经营管理技术评价中的应用。以追肥、叶面施肥和土壤管理为试验因素,对比追肥因素中尿素、二铵、复合肥;叶面施肥因素中微肥、硼砂;土壤管理因素中扩穴、松土对山杏产量的影响。正交试验结果表明,对于追肥因素来说,尿素的效果最佳k=16.072;对于叶面施肥因素来说,硼砂的效果最佳k=16.128;对于土壤管理因素来说,松土的效果最佳k=16.380。以尿素、硼砂、松土水平组合为最好。试验的实际产量这种组合产量最大,达到320.04 kg/hm2。
The application of orthogonal experiment to the assessment of the management of almond forest was investigated. The impacts of three factors on the yields of almond kernel were probed ,i. e. ,to-dressing （urea ,ammonium hydiogen phosphate and compounded fertilizer）,leaf-fertilizing （rnicronutrient fertilizer and borate）and soil management（ditch ploughing and scarifying）. The results of orthogonal experiment showed that satisfactory benefits could be obtained within the three factors .urea（k=16. 072）,borate （k= 16. 128） and scrafying （k=16. 380）. Therefore,the best results could beachieved by the combination of applying these three management.urea for top-dressing ,borate for leaf spraying, and scarifying for soil management. The yield of almond kernel was as high as 320. 04 kg/hm^2 under this combination management.
