Application analysis of water and fertilizer coupling of different drip irrigation techniques on facility cucumber
[Objective]To explore the effects of different drip irrigation methods on the growth and yield of cucumber under the condition of yellow loam in Lanzhou.[Methods]The effects of drip irrigation under mulch,under drip irrigation,under mulch with inner patch,under ridge film furrow irrigation and by water and fertilizer coupling treatment on physiological traits,yield and quality of cucumber were investigated.The orthogonal test of three factors and three levels was used,and the optimal combination scheme of three factors was obtained by variance analysis and regression.[Results]The three factors had little effect on the physical and chemical properties of the plant,but significant effects on the physical and chemical properties,yield,quality and WUE of the fruit.The order of influence was drip irrigation mode>irrigation amount>fertiliza-tion amount.The optimal combination of three factors was determined as follows:drip arrow drip irrigation un-der film,irrigation amount of 66.13 m3/hm2,fertilization amount of 25.2 kg/hm2,and the highest yield of cucumber in solar greenhouse was 256,942.52 kg/hm2.[Conclusion]Both drip arrow drip irrigation and in-laid patch drip irrigation saved water and fertilizer and cost as well without affecting the yield and quality of cu-cumber.Among them,drip-arrow drip irrigation under film had the best effect and was worthy of promotion.
