中文摘要	【目的】研究生物质炭基肥不同施用量对旱塬区苹果生长发育的影响,为黄土高原半干旱苹果产区合理施肥提供依据.【方法】选择树龄10a寒富苹果为试验材料,设置1 050g/株(T_1)、1 500g/株(T_2)、1 950g/株(T_3)、2 400g/株(T_4)4个生物质炭基肥施肥梯度和不施肥(T_5)、常规施肥量(T_6)两个对照处理,测定分析苹果树体生长、叶片营养和果实品质等指标.【结果】T_3的平均单果质量显著高于其他处理,比T_1、T_2、T_4、T_5、T_6分别提高了25.50%、12.94%、14.44%、30.75%、15.08%;T_3的产量为28.62t/hm~2,显著高于其他处理,分别比T_1、T_2、 T_4、T_5、T_6提高了76.34%、27.71%、32.13%、113.90%、44.40%.T_3叶片N含量比T_1、T_2、T_4、T_5、T_6提高了7.56%、3.45%、0.48%、16.19%、14.22%,其中与T_1、T_5、T_6差异显著;T_3的P含量比T_1、T_2、T_5、T_6显著提高了22.36%、6.74%,、32.60%、15.33%,T_3处理的K含量比T_1、T_2、T_4、T_5、T_6分别显著提高了14.92%、11.19%、 3.93%、19.40%、11.19%.T_4的VC含量比T_1、T_2、T_3、T_5、T_6分别显著提高了22.86%、12.77%、8.88%、32.40%、 18.81%;T_4的可溶性糖含量比T_1、T_2、T_3、T_5、T_6分别显著提高了19.24%、26.49%、29.60%、41.04%、17.32%.果实硬度、果形指数、叶片厚度和叶片Ca含量各处理间差异不显著.【结论】苹果园土施生物质炭基肥有利于树体生长和果实品质提高;施用量1 950g/株效果最好.
英文摘要	【Objective】The effect of different application amount of biochar-fertilizer on apple tree growth in semiarid regions was studied,to provide scientific evidence for reasonable fertilization in semi-arid areas on the Loess Plateau where apple trees were grown.【Method】Ten-years-old trees of apple cultivar Hanfu were employed,and fertilized with biochar fertilizer at four levels:1 050g/plant(T_1),1 500g/plant (T_2),1 950g/plant(T_3),2 400g/plant(T_4),and with two control treatments:no fertilization(T_5)and conventional fertilization(T_6).The indicators of the apple tree growth,leaf nutrition and fruit quality were measured and analyzed.【Result】The mean weight of single fruit of T_3was significantly higher than that of other treatments,and it increased by 25.50%,12.94%,14.44%,30.75%and 15.08%,respectively,compared with T_1,T_2,T_4,T_5 and T_6.The yield of T_3was 28.62t/hm~2,which was 76.34%,27.71%,32.13%, 113.90%and 44.40%higher,respectively,than T_1,T_2,T_4,T_5 and T_6.The N content in leaves of T_3was significantly increased by 16.19%and 14.22%compared with T_5and T_6,and by 7.56%,3.45%,0.48% compared with T_1,T_2,and T_4.The N content of T_3did not differ significantly with T_1,but differed significantly with T_2and T_4.The P content of T_3 was 22.36%,32.60%and 15.33% higher,respectively,than T_1,T_5 and T_6,and 6.74% higher than T_2,which was not statistically significant.The K content of T_3 was 14.92%,11.19%,3.93%,19.40%,11.19% greater,respectively,than T_1,T_2,T_4,T_5 and T_6,and each of the differences were significant statistically.The VC content of T_4 was 22.86%,12.77%,8.88%,32.40% and 18.81%higher,and its soluble sugar content was 19.24%,26.49%,29.60%,41.04% and 17.32% higher,respectively,than that of T_1,T_2,T_3,T_5 and T_6, and each of the differences was significant statistically. There was no significant difference found among treatments in fruit hardness,fruit shape index,leaf thickness and leaf Ca content.【Conclusion】It was showed that the application of biochar fertilizer in apple cultivation was beneficial to its growth and fruit quality,and the treatment of fertilization (i.e.1 950 g/plant)was the best.
