| Abstract: | On the basis of field experiment,resarch has been conducted in sensitive period of moisture, key irrigation period,loss function of water deficiency and sensitive index of water deficiency about a natural grass+weed coenosium. Results provide the basis for improving management level of irrigation grassland, optimization scheduling of water resources engineering and evaluation of irrigation grassland economic effect. |
