| 摘 要： | 通过大田施肥试验研究了尿素、过磷酸钙、硫酸钾不同施用水平对无核白葡萄产量与品质的影响.结果表明,氮磷钾合理配施可有利于维持葡萄树体营养生长和生殖生长的平衡,适宜配比可增加葡萄坐果数与单果重,提高产量;并增加葡萄果实中Vc、可溶性固形物和有机酸含量,改善果实品质.整体而言,葡萄生长季的栽培过程中氮磷钾(N:P2O5:K2O)的追施比例为1:0.5～0.8:1时,表现出最佳的经济效益和最高的产量.

| Abstract: | The field experiment was carried out to study the influences of nitrogen(N),phosphorus(P) and potassium(K) fertilizers on the fruit yield and quality of Thompson Seedless.The results showed that adequate application of N and K fertilizer can maintain the balance of vegetative and reproductive growth of the grapevine,promoting the growth of fruit,increased fruit number and fruit weight effectively as well.In addition,contents of Vc,soluble solid and organic acid of grape were increased,and then the quality o... |
