据《园艺学报》2013年第10期《土壤pH对富士苹果生长及碳氮利用特性的影响》(作者葛顺峰等)报道,以2年生富士(Malus×domestica Borkh.‘Red Fuji’)/平邑甜茶(Malus hupehensis)为试验材料,采用碳氮双标记技术,研究了6种不同pH值(6.83、6.40、5.87、5.29、4.58和3.82)土壤处理对植株生长及碳氮利用特性的影响。结果表明,苹果植株根系、地上部、植株总干重、根冠比、叶片净光合速率和15N利用率均随土壤pH值的降低而降低,且土壤pH值越低
According to Journal of Horticulture, No. 10, 2013, “Effect of Soil pH on Growth and Carbon and Nitrogen Utilization Characteristics of Fuji Apples” (by Ge Shunfeng, et al.) Reported that two-year-old Malus × domestica Borkh ’Red Fuji’ The effects of six soil treatments with different pH values (6.83, 6.40, 5.87, 5.29, 4.58 and 3.82) on the plant growth and carbon and nitrogen utilization characteristics were studied by using the carbon-nitrogen double labeling technique in Malus hupehensis. The results showed that the root, shoot, total dry weight, ratio of shoot to root, net photosynthetic rate of leaves and 15N utilization rate of apple plants decreased with the decrease of soil pH value, and the lower the soil pH value
