摘　　要：在日光温室内以卡鲁索 (Caruso)和辽粉杂 3号为试验品种 ,进行长季节栽培 ,在整个生育期中 ,灌水次数为 18～ 2 1次 ,每 667m2 每次灌水量为 15～ 17m3,总灌水量为 2 92 .3 2～ 3 2 4 .4 6m3,2 0cm土层土壤含水量始终保持在田间持水量的 70 %～ 10 0 %。试验过程中除了施基肥外 ,分别在番茄的坐果期、果实膨大期、采收初期和采收中期进行追肥 ,每次追肥量相同 ,即 667m2 追施尿素 10kg,磷酸二铵 15kg ,硫酸钾The tomato varieties of Caruso and Liao Fenza 3 were cultivated under long term in solar lean to greenhouse. The number of irrigation frequency were 18-21,the average amount of water in each irrigation was 225-255m 3·hm -2 ,the total amout of irrigation water was 4384.8-4866.9m 3·hm -2 throughout the whole tomato growth period. The water content of 20cm soil lager was always kept 70%-100% of field water holding capacity. 150t organic fertilizer,210kg Urea,375kg NH 4H 2PO 4 and 375kg K 2SO 4 fertilizer per hectare were used before transplanting,and 150kg Urea,225kg NH 4H 2PO 4 and 225kg K 2SO4 fertilizer were dressed each time at fruit seetting stage,fruite formation stage,early stage and middle stage of harvesting per hectare.
