摘要
通过田间小区试验的方法,研究高磷钾土壤不同施肥水平对设施番茄产量、品质、养分吸收及土壤中养分变化的影响。试验结果表明,不同处理间产量差异不显著,随着氮、磷、钾施用量的增加,各处理番茄植株和果实中氮和钾的吸收量增加,叶、茎、果实中钾的吸收量明显高于氮、磷的吸收量;每1 hm^2 N、P2O5、K2O的追肥量为277.5、83.25、416.3 kg时,番茄产量较高,品质最好,且养分投入量低,土壤中盐分和养分累积相对较低,但磷、钾吸收量偏高,因此在该施肥方案基础上增施氮肥,降低磷、钾肥的施用量更利于番茄生长。
The effects of different fertilization levels on the yield,quality and nutrient absorption of tomato planted on soil with high contents of phosphorus and potassium and soil nutrients were studied by using the field plot test method.The results showed that the yield of different treatments had no significant difference.As the fertilizer application amounts of N,P and K increased,the absorption amounts of N and K2O in plants and fruits of tomato improved,and the absorption amount of K2O was obviously higher than the absorption amounts of N and P2O5.When the topdressing amounts of fertilizer N,P2O5 and K2O were 277.5,83.25 and 416.3 kg/hm^2,the treatment had higher tomato yield,the best quality,low nutrient input,relatively low soil salt and nutrient accumulation,but its absorption amounts of P2O5 and K2O were relatively high.Therefore,on the basis of this fertilization scheme,it was more conductive to tomato growth by increasing application amount of N and reducing application amounts of P and K.
