摘 要:年在国家果树种质李杏圃,对年生串枝红杏树于果实成熟期进行解体分析。其营养20028积累量,氮为,磷,钾,钙,镁;分别占树体干重的,445.60g80.12g351.68g624.05g91.81g0.717%,,;除钙外,均以果实中积累最多,分别为、、、0.129%0.566%1.004%0.148%,142.14g24.95g211.58g,占各自营养总量的、、、。氮、磷、钾、钙、镁在各器官中的相对含24.95g31.89%31.14%60.16%27.18%量,除钾以果实最高外,均以叶片为最高,分别为、、,。每生产果实,2.56%0.39%3.03%0.83%50kg年吸收氮,磷,钾,钙,镁;其比例为。426.83g69.46g449.14g372.47g88.61g10押1.6押10.5押8.7押2.This research was carried out on 8-year-old Chuanzhihong apricot trees at National Germplasm Repository for Plum and Apricot in 2002.The fruit were sampled and analizd after harvesting.The mount of nutrition for N,P,K,Ca and Mg were 445.60 g,80.12 g,351.68 g,624.05 g,91.81 g with proportions of 0.717%, 0.129%, 0.556%, 1.004% and 0.148% in trees respectively. Among them, N, P, K, and Mg expressed the most accumulation of 142.14 g,24.95 g,211.58 g,and 24.95 g in the fruit which shared 31.89%,31.14%,60.16% and 27.18% of their own whole nutrition amount. Leave and fruit acculated Ca more,while branches and stems acculated less.The relative contents of N,P,K,Ca,and Mg in leave were 2.56%,0.39%,3.03%and 0.83% respectively which were higher than those in the other organs.The studys showed that trees could produce 50 kg fruit by absorbing N 426.83 g,P 69.46 g,K 449.14 g,Ca 372.47 g,Mg 88.61g to produce every year at a ratio in 10:1.6:10.5:8.7:2.0.
