- Abstract: Film hole irrigation is a new type of film‐mulched irrigation technology. To investigate the influences of five factors—bulk density, initial soil water content, irrigation depth, film hole diameter and infiltration time—on the infiltration characteristics of film hole irrigation, 12 experiments were conducted. The infiltration characteristics considered were the cumulative infiltration ( I ), infiltration rate ( i ) and average increment of soil water content (∆ θ ). Two empirical models were established that describe the relationship of I with ∆ θ and various influential factors. The proposed models of I and ∆ θ had a root mean square error of 5.82 ml and 0.003 cm 3 cm −3, respectively. The results revealed that the effects of initial soil water content and irrigation depth on I were not significant ( P > 0.05) and that the ranking of factors according to degree of influence, from large to small, was infiltration time, soil bulk density and film hole diameter. Soil bulk density, initial soil moisture, irrigation depth and film hole diameter had highly significant effects on ∆ θ ( P < 0.01), and their ranking according to degree of influence, from large to small, was initial moisture content, soil bulk density, irrigation depth and film hole diameter. © 2020 John Wiley & Sons, Ltd.

Rėsumė: L'irrigation par film troué est un nouveau type de technologie d'irrigation par paillage de film. Pour étudier les influences de cinq facteurs—la densité apparente, la teneur initiale en eau du sol, la profondeur d'irrigation, le diamètre du trou de film et le temps d'infiltration—sur les caractéristiques d'infiltration de l'irrigation par film troué, 12 expériences ont été menées. Les caractéristiques d'infiltration considérées étaient l'infiltration cumulative ( I ), le taux d'infiltration ( i ) et l'augmentation moyenne de la teneur en eau du sol (∆θ). Deux modèles empiriques ont été établis qui décrivent la relation de I avec ∆θ et divers facteurs influents. Les modèles proposés de I et ∆θ avaient une erreur quadratique moyenne de 5.82 ml et 0.003 cm 3 cm‾ 3, respectivement. Les résultats ont révélé que les effets de la teneur initiale en eau du sol et de la profondeur d'irrigation sur I n'étaient pas significatifs ( P > 0.05) et que le classement des facteurs selon le degré d'influence, du plus grand au plus petit, était le temps d'infiltration, la densité apparente du sol et le film diamètre du trou. La densité apparente du sol, l'humidité initiale du sol, la profondeur d'irrigation et le diamètre du trou du film ont eu des effets très significatifs sur ∆θ ( P < 0.01), et leur classement selon le degré d'influence, de grand à petit, était la teneur en humidité initiale, la densité apparente du sol, la profondeur d'irrigation et le diamètre du trou du film. © 2020 John Wiley & Sons, Ltd. … (more)
