| 摘 要： | 对日光温室渗灌和沟灌的土壤环境，室内空气环境，作物生育及病毒状况，水分利用效率等进行了研究，结果表明，与沟灌相比，渗灌可增加土壤水稳定性团粒81．4％，降低土壤容重21．2％，增加土壤孔隙度29．0％，提高土壤温度1．1－1．7℃，降低空气湿度13．4％，节约灌溉用水36．7％，而且能促使作物早熟，提高作物产量，减少作物病害，降低生产成本，是目前日光温室理想的灌溉技术。

| Abstract: | The differences of soil and air environments, crop growth, development and diseases, and water use efficiency of seeping irrigation from furrow irrigation were studied. Results indicated that compared with furrow irrigation, seeping irrigation could increase soil waterstable granular by 81.4%, soil porosity by 29.0% and soil temperature by 1.1-1.7 degrees C respectively, decrease bulk density by 21.2% and relative air humidity by 13.4% respectively, and save irrigation water by 36.7%. In addition, seeping irrigation could also accelerate crop maturity and increase yield, reduce crop diseases and production cost. Therefore, seeping irrigation was an ideal irrigation technique in sunlight greenhouse at present. |
