为给无性系良种的栽培技术提供施肥的科学依据,1981—1982年对安徽3号、安徽7号进行了氮磷钾施肥效果的研究,结果表明,两个良种因其生长特性不同,对氮磷钾肥的吸收有明显区别。由于影响茶树矿质营养因素是多方面的,特别是土壤条件更有直接关系,为此,在1983—1985年又对这两个品种在不同土壤条件下,对氮磷钾的吸收利 In order to provide the scientific basis for fertilizing clones of cultivated elite varieties, the effects of NPK fertilizer application on Anhui No.3 and Anhui No.7 from 1981 to 1982 were studied. The results showed that the nitrogen and phosphorus fertilization effects of two elite varieties on nitrogen P and K absorption significantly different. As the factors that affect tea mineral nutrition are many, especially the soil conditions are more directly related to this, in 1983-1985 these two cultivars in different soil conditions, the absorption of nitrogen, phosphorus and potassium
