摘要
根据土壤—植物—大气连续系统原理 ,1989～ 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 ,分析了水稻的需要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。
Pot, plot and field experiments with lysimeter were conducted at an irrigation experimental station to investigate water requirement of rice and soil moisture changes in paddy field. The relationship between soil water condition and evapotranspiration intensity of rice was discussed. The effect of different irrigation models on evapotranspiration of rice and the effect of soil water stress on rice yield were studied. Water saving and high yield irrigation models of rice and soil moisture potential control criteria are suggested.
