干旱区克瑞森无核葡萄水肥耦合效应

Effects of water and fertilizer coupling on Crimson seedless grapes at arid areas

以克瑞森葡萄为试材,探讨了不同水肥组合对葡萄产量和品质的影响,旨在寻找适合葡萄生长的水肥组合,为葡萄栽培提高水肥的利用效率提供理论依据。结果表明:总灌水量为6 000 m3/hm2时具有较高的产量和水分利用效率,在该灌水量水平下施N、P、K肥总量420 kg/hm2处理的葡萄产量较好。中等浇水量和高施肥量的处理是比较理想的水肥组合。

Taking Crimson seedless grape as materials, effects of different fertilizer and fertilizer combinations on yield and quality of grape were researched, in order to find the suitable combination for grape growth and provide a theoretical basis for improving utilization efficiency of water and fertilizer in grape cultivation. The results show that yield and water utilization efficiency is high when the total irrigation amount is 6 000 m3/hm2, and grape yield is better at the irrigation level when the total amount of N, P and K fertilizers is 420 kg/hm2. In summary, the treatment of secondary water amount and high fertilizer application amount is an ideal water and fertilizer combination.
