Abstract
In order to improve utilization of soil moisture in maize production,taking maize as experimental material,the effects of different soil moisture content on growth and yield of maize were studied by comparison observation for irrigation and non-irrigation.The results showed that the soil moisture fluctuation trends were similar between surface layer(0~30cm)and deep level(30~50cm)in the test field,but the surface layer was more easily influenced by the outside factors.Different soil humidity had significant effects for maize growth,dry weight and yield during growth period.Irrigation provided more water in favor of dry matter accumulation on the ground.Appropriate irrigation was more conducive to the stable and high production of maize after milk stage.
