Title: Preliminary Study on Different Irrigation Methods in Woodland of the Physical Properties of Soil Moisture
Abstract: Conclusions was drawn out through measurement of bulk density,porosity and water-holding capacity within 50 cm under the different irrigations for woodland land soil at north-mountain of Lanzhou.The results showed trat the soil bulk density decreased in sprinkle irrigated soil than that of non-irrigated and flood irrigated soil,but capillary porosity and total porosity of soil increased,accordingly soil saturated moisture capacity,capillary moisture capacity,and field moisture capacity was also increased,however,non-capillary porosity hadn't shown the desire results due to unknown reasons.This indicated that sprinkle irrigation can reduce soil bulk density to a certain extent,in addition to improves soil porosity conditions and soil moisture capacity,finally improves physical properties of soil moisture.Instead,the flood irrigation had not improved the physical properties of soil moisture,but also led to decreased utilization of the water.Therefore,sprinkle irrigation should be the preferred method in woodland.
