2007年‘京亚’葡萄果实成熟期,对树体进行了解体分析。结果表明:全树营养含量,氮82.63g、磷37.00g、钾104.47g、钙152.43g、镁24.25g,分别占树体干重的0.784%,0.351%,0.991%,1.446%,0.230%。氮、磷在叶片中积累最多,分别为23.13、9.51g,分别占总氮、总磷的27.99%、25.70%;主干中磷积累量虽多,但那是5年的积累量。钾在果实中积累最多,为47.88g,占总钾的45.83%。每生产100kg果实当年吸收氮396.59g、磷182.88g、钾552.80g、钙593.26g、镁101.14g,其比例为10.0∶4.6∶13.9∶15.0∶2.6。
2007 ’Beijing Asia’ grape fruit maturity, the tree was disintegrated analysis. The results showed that the total nutrient content of the whole tree were 82.63g nitrogen, 37.00g phosphorus, 104.47g potassium, 152.43g calcium and 24.25g magnesium, accounting for 0.784%, 0.351%, 0.991%, 1.446% and 0.230% of the dry weight of the tree respectively. Nitrogen and phosphorus accumulate the most in the leaves, which are 23.13 and 9.51 g, accounting for 27.99% and 25.70% of the total nitrogen and total phosphorus, respectively. Although the accumulation of phosphorus in the trunk is large, it is the accumulation in five years. Potassium accumulated most in fruits, accounting for 47.88g, accounting for 45.83% of total potassium. Each production of 100kg of fruit that year to absorb nitrogen 396.59g, phosphorus 182.88g, potassium 552.80g, calcium 593.26g, magnesium 101.14g, the ratio of 10.0: 4.6: 13.9: 15.0: 2.6.
