以水蜜桃品种“皮球桃”为试材,采用正交实验设置9组配方施肥方案,研究了不同施肥处理对土壤理化性质和果实品质的影响,以期获得改善土壤理化性质和果实品质的最佳施肥配方。结果表明:在各处理基肥、萌芽肥配方相同的情况下,处理6(株施入硬核肥磷酸一铵0.8kg+尿素0.2kg和采前肥硫酸钾1.75kg),处理8(株施入硬核肥磷酸一铵1.1kg+尿素0.2kg和采前肥硫酸钾1.45kg),处理9(株施入硬核肥磷酸一铵1.1kg+尿素0.2kg和采前肥硫酸钾1.75kg)能显著改善土壤理化性质和果实品质;667 m~2施入(50株)基肥干鸡粪300~375kg+过磷酸钙100~150kg+尿素12.5~17.5kg+硫酸钾50.0~62.5kg、萌芽肥尿素12.5kg+硼砂7.5kg、硬核肥磷酸一铵40~55kg+尿素10kg和采前肥硫酸钾72.5~87.5kg效果最佳。
With peach variety “peach peach ” as test material, orthogonal experiment was used to set up nine groups of fertilization plan to study the effects of different fertilization treatments on soil physical and chemical properties and fruit quality in order to obtain the soil physical and chemical properties and fruit quality Best fertilizer formula. The results showed that under the condition of the same base fertilizer and budding fertilizer formula, the treatment 6 (strain was implanted with 0.8kg of ammonium phosphate mono-ammonium and 0.2kg of urea and 1.75kg of potassium sulfate) 1.1 kg of ammonium phosphate monoammonium phosphate + 0.2 kg of urea and 1.45 kg of pre-harvest fertilizer potassium sulphate), treatment 9 (applying 1.1 kg of ammonium phosphate monoammonium fertilizer, 0.2 kg of urea and 1.75 kg of pre-harvest fertilizer potassium sulphate) can significantly improve soil Physical and chemical properties and fruit quality; 667 m ~ 2 applied to 50 basal manure dry chicken manure 300 ~ 375kg + superphosphate 100 ~ 150kg + urea 12.5 ~ 17.5kg + potassium sulfate 50.0 ~ 62.5kg, sprouted urea fertilizer 12.5kg + borax 7.5kg, Hard ammonium phosphate monoammonium 40 ~ 55kg + urea 10kg and pre-harvest fertilizer potassium sulfate 72.5 ~ 87.5kg best.
