对烟台和威海地区15 124个苹果园、611个梨园、1 581个甜樱桃园土壤pH值测定表明,烟台和威海的果园均不同程度地发生土壤酸化,且果园土壤酸碱性区域差异很大。强酸性土壤(pH值<5.0)果园占4.69%~28.47%,酸性土壤(pH值5.0~6.5)果园占35.82%~71.53%。其中苹果强酸性土壤园比例,由大到小依次为荣成28.47%,环翠23.49%,蓬莱12.67%,招远11.75%,栖霞11.27%,文登10.67%,乳山8.40%,龙口6.65%。苹果园土壤pH值≤5.5的需改良园所占比例,由大到小依次为荣成61.80%,环翠56.69%,文登34.23%,招远32.03%,蓬莱29.88%,栖霞27.70%,乳山26.20%,龙口15.73%。梨园土壤pH值≤5.5的需改良园所占比例为18.49%。甜樱桃园土壤pH值≤6.0的需改良园所占比例为莱山53.31%,福山18.43%。
The soil pH of 15 124 apple orchards, 611 pear orchards and 1 581 sweet cherry orchards in Yantai and Weihai showed that soil acidification occurred in different degrees in the orchards of Yantai and Weihai, and the acid and alkali areas of orchards differed greatly . Strong acid soil (pH <5.0) accounted for 4.69% ~ 28.47% in orchards, and acid soil (pH5.5 ~ 6.5) accounted for 35.82% ~ 71.53% in orchards. Among them, the proportion of strong acidic soil garden of apple is 28.47%, 23.49% of Hui Cui, 12.67% of Penglai, 11.75% of Zhaoyuan, 11.27% of Qixia, 10.67% of Wendeng, 8.40% of Rushan and 6.65% of Longkou. Apple orchards soil pH value ≤ 5.5 need to be improved garden proportion, descending order of Rongcheng 61.80%, Tsui Tsui 56.69%, Wendeng 34.23%, Zhaoyuan 32.03%, Penglai 29.88%, Qixia 27.70%, Rushan 26.20% , Longkou 15.73%. Pear orchard soil pH ≤ 5.5 need to be improved garden accounted for 18.49%. The proportions of sweet orchards whose soil pH value ≤ 6.0 need to be improved are 53.31% of Laishan and 18.43% of Fukuyama.
