Abstract:
Taking ‘Yipintianxia 208’ cantaloup variety as materials，the effects of water-fertilizer coupling on growth，yield and quality of cantaloup under the conditions of alternate root partition and drip irrigation were investigated，irrigation maximum and fertilizer amount as the two factors were studied.The results showed that plant growth，root activity and pulp thickness increased with irrigation maximum increased，but the content of nutrition and yield first increased and then decreased.At the same irrigation maximum，double side fertilizing or more fertilizer did good to plant growth，root activity，pulp thickness，content of nutrition and yield.Alternate water and fertilizer coupling was better than always unilateral coupling to increase plant growth，root activity，pulp thickness，content of nutrition and yield.But there should be the best irrigation maximum for leaf area，root activity and yield.On the occasion of water deficit and low fertility，alternate water-fertilizer coupling and always unilateral coupling had inapparent effect on leaf area，root activity and yield.Enough water could diminish the difference of effect on leaf area between high fertility and low fertility.The T5（irragation maximums 85%，alternate drip irrigation，nitrogen application 120 kg/hm2,P2O5 150 kg/hm2,K2O 180 kg/hm2,double side fertilizing）of water-fertilizer coupling was the best plan for high quality and high efficiency.
