摘  要：
采用盆栽方法进行了不同施磷(P_2O_5)水平下,日光温室番茄产量、不同生育期番茄磷素分配、干质积累、土壤速效磷含量和酶活性研究,并确定了适宜番茄生长的最佳施磷量与土壤速效磷含量。结果表明,随着磷肥施用量的增加,土壤速效磷含量及番茄各组织含磷量相应增加;当施用P_2O_5达到0.53 g/kg(处理5),土壤速效磷含量在60～77 mg/kg时,较适宜番茄生长,番茄产量和单果重达最高,根系和茎叶干物质积累也达到最好水平。当施磷量超过0.53 g/kg时,造成土壤和植株磷累积过高,易引起土壤盐害,降低土壤酶活性,从而降低干物质积累和番茄产量,影响土壤的可持续利用。

摘  要：
Phosphorus(P)is one of the most important macronutrient elements for plant growth.High residual P in greenhouse soils was frequently found because P is relatively insoluble and has a long residence time in the soil.In order to find an optimal level of soil available phosphorus for tomato production,a pot experiment was conducted to investigate the effect of phosphorus(P_2O_5)on to tomoto yield,phosphorus partitioning in different organs of tomato,dry matter accu- mulation,soil available P and enzyme activities.The results showed that with the increase of P application rate,the con- tent of available P in soil and P content in all organs of tomato significantly increased.The tomato yield,signal fruit weight and dry matter accumulation reached maximum when P_2O_5 were 0.53 g/kg.The optimal content of soil available P was 60-77 mg/kg for tomato production.Excessive P application(>0.53 g/kg)caused a high accumulated P in soil and plant,resulting in the salt toxicity,low soil enzyme activities,declined dry matter and low tomato yield.
