摘　　要：为了给中国番茄测土施氮提供有效参考,使用“零散试验数据整合法”和“养分平衡–地力差减法新应用公式”,进行中国番茄土壤氮素丰缺指标与推荐施氮量研究。结果表明:中国番茄土壤碱解氮第1~7级丰缺指标依次为:≥303.1、189.5~303.1、118.5~189.5、74.1~118.5、46.3~74.1、29.0~46.3和<29.0 mg/kg;土壤全氮第1~7级丰缺指标依次为:≥3.0、2.0~3.0、1.3~2.0、0.8~1.3、0.6~0.8、0.4~0.6和<0.4 g/kg;土壤有机质第1~6级丰缺指标依次为:≥77.3、36.6~77.3、17.4~36.6、8.2~17.4、3.9~8.2和<3.9 g/kg,其中,露地番茄土壤有机质第1~7级丰缺指标依次为:≥55.3、32.8~55.3、19.4~32.8、11.5~19.4、6.8~11.5、4.1~6.8和<4.1 g/kg,设施番茄土壤有机质第1~4级丰缺指标依次为:≥43.4、14.6~43.4、4.9~14.6和<4.9 g/kg。当氮肥当季利用率为40%、番茄目标产量为120 t/hm^(2)时,土壤氮素丰缺级别第1~7级的推荐施氮量依次为0、81、162、243、324、405和486 kg/hm^(2)。In order to provide a theoretical basis for nitrogen(N)application in tomato soil testing,the abundance-deficiency index(ADI)of soil N and the recommended N fertilizer application rate(RNFAR)for tomatoes in China were established by using the method of integrating piecemeal experiment data and the new application formula of nutrient balance-soil fertility difference subtraction.The results showed that ADIs of soil alkaline hydrolysis N for tomatoes in China from the 1st to 7th levels were≥303.1,189.5–303.1,118.5–189.5,74.1–118.5,46.3–74.1,29.0–46.3 and<29.0 mg/kg,respectively;ADIs of soil total N for tomatoes in China from the 1st to 7th levels were≥3.0,2.0–3.0,1.3–2.0,0.8–1.3,0.6–0.8,0.4–0.6 and<0.4 g/kg,respectively;ADIs of soil organic matter(all fields)for tomatoes in China from the 1st to 6th levels were≥77.3,36.6–77.3,17.4–36.6,8.2–17.4,3.9–8.2 and<3.9 g/kg,respectively;ADIs of soil organic matter(open fields)for tomatoes in China from the 1st to 7th levels were≥55.3,32.8–55.3,19.4–32.8,11.5–19.4,6.8–11.5,4.1–6.8 and<4.1 g/kg,respectively;ADIs of soil organic matter(facility fields)for tomato planting in China from the 1st to 4th levels were≥43.4,14.6–43.4,4.9–14.6 and<4.9 g/kg,respectively.When N fertilizer use efficiency was 40%in tomato season and projected tomato yield was 120 t/hm^(2),RNFAR from the 1st to 7th levels of soil N abundance-deficiency were 0,81,162,243,324,405 and 486 kg/hm^(2),respectively.
