Seeping irrigation effect in sunlight greenhouse

Abstract

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 1.1～1.71℃ 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.

Key words: Sunlight greenhouse, Seeping irrigation, Furrow irrigation, Water-saving, grazing, Inner Mongolia typical steppe, litter decomposition, soil animal community
