摘要
为改善桃树经济性状,选取9年生湖景蜜露桃园为研究对象,以常规施肥为对照,选用不同配比生物炭、EM菌有机肥与化肥混施,研究了其对桃园土壤肥力、树体生长及果实品质的影响。结果表明:生物炭、EM菌有机肥和化肥混施后:①土壤pH值提高,土壤肥力指标也明显提高,在施用量小于对照的情况下有效养分值仍不低于或大于对照;②树体有效结果枝数量显著增加,旺长枝数量显著下降,根系活力增强;③桃果实品质指标显著提高。综合试验研究结果和投入产出比,以株混施生物炭∶EM菌有机肥∶化肥(高钾型三元复合肥)=3.750∶6.250∶0.375的复混肥10.375 kg为最优。
In order to improve the economic properties of peach trees,the 9-year-old‘Hujingmilu’garden was selected as the research object,the conventional fertilization was used as the control,and the mixed application of different proportions of biochar,EM bacteria organic fertilizer and chemical fertilizer was used to study its effects on soil fertility,tree growth and fruit quality.The results showed that after the combined application of biochar,EM bacteria organic fertilizer and chemical fertilizer:①The pH value and fertility index of soil increased significantly.When the application rate was less than the control,the effective nutrient value was still not lower than the control;②The number of effective fruiting branches increased significantly,the number of prosperous and long branches decreased significantly,and the root activity increased;③The quality index of peach fruit was significantly improved.Based on the experimental results and input-output ratio,the optimal fertilization method is 10.375 kg compound fertilizer with the ratio of biochar:EM bacteria organic fertilizer∶chemical fertilizer(high potassium ternary compound fertilizer)=3.750∶6.250∶0.375.
