Abstract:

In order to study the effect of different irrigation methods and ridge planting experiments on water use efficiency and yield of potato in dryland,and to identify an optimal ridge planting and irrigation combination mode of potato with high yield and water use efficiency simultaneously,and further provide a theoretical basis for the production efficiency of dryland potato.The two-factor experiment was persistently performed in Lanxian County Shanxi Province during two potato growing seasons(2019—2020).The three ridge planting,including conventional ridge cultivation(M1),concave ridge cultivation technique(M2)and outdoor planting(M3);the two irrigating including hydraulic driving zonal sprinkler(G1)and drip irrigation(G2),deeply exploring the effects of ridge planting and irrigation and their interaction effects on water use efficiency and yield of dry potato.The results showed that irrigation and ridge planting had obvious regulation effects on water use efficiency and yield of dry potato.Compared with M1 and M3,M2 could significantly increase soil use efficiency water storage consumption.Under G1 treatment,the water use efficiency and yield of M1 and M2 treatments increased by 14.08%,13.58%,and 23.28%,21.92%,respectively,compared to M3;under G2 treatment,the water use efficiency and yield of M1 and M2 treatments increased by 11.88%,11.50%,and 22.05%,20.45%,respectively,compared to M3,and the combination of concave ridge cropping + hydraulic driving zonal sprinkler irrigation treatment combination G1M2 had the highest yield.Under the same ridge planting,the water use efficiency and yield of hydraulically driven zonal sprinkler irrigation(G1)were the highest.Based on the regulating effects of ridge planting and irrigation on water use efficiency and grain yield,the G1M2 treatment could help synchronously to improve the grain yield and water use efficiency.This can be an optimal model of ridge planting and irrigation combination treatment of dry potato area of Shanxi Province.
