摘要
198 9～ 1998年在沈阳农业大学灌溉试验场通过盆载、蒸渗仪、小区及大田进行试验研究 ,分析了水稻的需水规律及稻田土壤水分能量的变化特点 ,论述了土壤水分状况与水稻腾发强度之间的关系、不同灌溉模式对水稻腾发量的调控作用以及水分胁迫对水稻产量的影响 ,提出了水稻节水高产灌溉模式和土壤水分能量调控标准。
Experiments were conducted in Irrigation Experimental Station of Shenyang Agricultural University under pots, lysimeters, and small field plots conditions in 1989～1998. Crop water requirement and soil moisture changes in paddy rice were investigated. The relationship between soil water contents and evapotranspiration rate of paddy rice was discussed. The effects of different irrigation schemes on evapotranspiration of paddy rice, and effects of soil water stress on paddy rice yield also were analyzed. The suitable irrigation schemes and soil water potential criteria for water-saving and high-yield were suggested.
