【摘要】 对日光温室膜下滴灌和沟灌方式下种植番茄的耗水量、产量和收入等进行了研究.结果表明,番茄盛果期日光温室膜下滴灌比沟灌室内空气相对湿度降低了18%;在全生育期膜下滴灌比沟灌耗水量减少了13.6%,可节约灌溉水25%;且滴灌条件下番茄可提早上市8 d,比沟灌增产30.7%,增加产值4.5万元/hm2,年产投比增高0.31.更多还原

【Abstract】 Water consumption,yield and income of tomatoes with drip irrigation under mulch and furrow irrigation in sunlight greenhouse were studied.The results indicated that:compared with furrow irrigation,drip irrigation under mulch lowered the relative humidity of the air in the sunlight greenhouse by 18 %,made the marketable date of tomato 8 days earlier,reduced water consumption by 13.8 %,saved irrigation water by 25 %,raised tomato yield by 30.7 %,achieved an output value increment of 4.5 million yuan(RMB)/ hm2,and enhanced the annual output and input ratio by 0.31.更多还原
