膜下滴灌棉花根系吸水模型研究
Root water uptake model in drip irrigation under mulched film
摘要
Abstract
The founction of root length density distribution in different growth stages of cotton was obtained through three groups of indoor bucket planting experiment. The water content in soil profile and the transpiration of cotton were derived by weighing the bucket before and after irrigation. And Feddes model was selected as the water uptake model of root system according to these indexes. The results of calculation with the model showed that the simulated soil moisture value nearly dovetailed the measured value, which showed that this model can accurately describe the moisture uptake of cotton root under mulched film with drip irrigation.关键词
