Abstract

In this study, the maize was selected as test crops, the effects of irrigation times, planting density and fertilization amount on maize morphology and yield under drip irrigation under film were discussed and compared with ridge irrigation. The results show that: Comprehensive irrigation times and planting density, the largest yield are 8426.4 kg/hm2 under irrigation 3 times. For the case of fertilization, given the planting density of 5500 plants/mu, irrigation 4 times, the amount of fertilizer as a variable, when the fertilizer rate of 450 kg/hm2, the maximum yield is up to 9162 kg/hm2. The yield and water production efficiency of drip irrigation under film were significantly increased by 32.9%, 18.0% and 42.5%, respectively, under the same irrigation amount, water production efficiency increased by 34.9%, 6.0%, 33.3%.
