水肥一体化滴灌对西昌设施‘克瑞森’无核葡萄果实膨大的影响

为筛选出适宜于‘克瑞森’无核葡萄果实膨大的水肥组合,在全生育期设置4个灌水量,4个施肥量梯度水肥一体化滴灌试验,探究其对‘克瑞森’果实膨大的影响效果。结果表明,主副互作对设施‘克瑞森’无核葡萄果实膨大的影响差异显著。灌水量5850、5400 m³/hm²与施肥量3150、2700 kg/hm²互作利于果实横径、纵径伸长、单粒重增加、硬度增强,以灌水量5850 m³/hm²与施肥量2700 kg/hm²互作效果最佳。灌水量5400、4950 m³/hm²与施肥量3150、2700 kg/hm²互作利于增加可溶性固形物含量,以灌水量4950 m³/hm²与施肥量3150 kg/hm²互作效果最佳。

Effects of Integrated Drip Irrigation of Water and Fertilizer on Fruit Enlarging of ‘Crimson’ Seedless Grape in Xi Chang

To screen suitable combination of water and fertilizer for fruit enlarging of ‘Crimson’ seedless grape, an integrated drip irrigation experiment of water and fertilizer with 4 irrigation amount gradients and 4 fertilizing amount gradients was set during the whole growth period to explore the effects on traits of fruit enlarging. The results showed that the interaction of main treatments and side treatments had significant effects on the indexes of the fruit enlarging traits of ‘Crimson’ seedless grape. The combinations of 5850 m ³/hm², 5400 m³/hm² irrigation amount and 3150 kg/hm², 2700 kg/hm² fertilizing amount were beneficial to the transverse elongation, longitudinal elongation, per berry weight increase, and hardness enhancement. The combination of 5850 m³/hm² irrigation amount and 2700 kg/hm² fertilizing amount had the best treatment effect. The combinations of 5400 m³/hm², 4950 m³/hm² irrigation amount and 3150 kg/hm², 2700 kg/hm² fertilizing amount were beneficial to the soluble solid content increase. The combination of 4950 m³/hm² irrigation amount and 3150 kg/hm² fertilizing amount had the best treatment effect.
