Abstract:
Use three-year-old T337 self-rooted rootstock young ‘Fuji’ apple tree as experimental material to analyse the entire tree main phenophase of the growth cycle.The entire tree into root xylem，root phloem，fibrous root，root stock xylem，root stock phloem，scoin xylem，scoin phloem，leaf，new shoots were analyzed.The biomass and P content of each part in different periods were measured.The results showed that in different periods P content in different parts of T337 self-rooted rootstock young ‘Fuji’ apple tree was different.And in the whole growth period，the xylem P content was low，phloem，fibrous root，leaf and shoot P content was higher.Tree dry matter，P allocation amount and proportion of leaf，new shoots and fibrous root were all higher than other parts.In the whole growth period，young apple tree′s total P accumulation amount was 1.17 g per plant，and 120 days before planting accounted for 35.90%，120 days after planting accounted for 64.10%.So recommendations of P fertilizer was 1.56 g per plant，before spring planting applies P fertilizer 0.56 g per plant，and 120 days after planting was 1.00 g per plant.
