摘　　要：以“华冠一号”番茄为试材,对番茄生育性状、产量及含糖量进行测定,研究氮磷钾配合施肥对番茄产量的影响。结果表明,缺氮区、缺磷区和缺钾区的产量性状与含糖量均低于氮磷钾正常区。其中,缺钾区株高比氮磷钾正常区降低13.12%;缺氮区茎粗比氮磷钾正常区降低了11.45%;缺氮区果实的含糖量比氮磷钾正常区降低了17.92%;正常氮磷钾区单株果重为3.55 kg,而无磷区仅为2.85 kg。缺磷区比氮磷钾区产量降低了19.78%,效益降低了19.05%。该研究结果表明设施番茄氮磷钾配方施肥的重要性。The growth trait,yield and sugar content of tomato were tested by using"Huaguan No.1"tomato.The effect of nitrogen,phosphorus and potassium combined with fertilization on tomato yield was studied.The tests showed that the growth traits,yield and sugar content in the tomatoes that lack of nitrogen,phosphorus and potassium were lower than that of normal.Among them plant height in deficient area was 13.12%lower than that in the nitrogen-phosphate-potassium normal area.The stem diameter in nitrogen-deficient area was 11.45%lower than that in normal area.The sugar content of fruit in nitrogen-deficient area was 17.92%lower than that in normal area.The fruit weight per plant was 3.55 kg in normal area,but only 2.85 kg in the phosphate-free area.The yield in phosphorus deficient area was 19.78%lower than that in normal area,and the benefit was 19.05%lower.The tests showed the importance of formula for nitrogen,phosphorus and potassium in greenhouse tomato.
