中文摘要:
      为了探索配方施肥对番茄产量、品质的影响,及番茄整个生育期氮、磷、钾吸收规律,在延庆区春大棚进行了番茄配方施肥试验。结果表明:氮、磷、钾肥667 m2施用量分别为12.40、5.28、16.68 kg 时,可获得最高产量(13 535 kg),且品质较优。不同施肥处理在番茄整个生育期对干物质积累和氮的养分吸收值差异不大,优化施肥处理的磷、钾养分吸收值明显高于传统和空白处理。番茄对氮、磷、钾的吸收值都较高,且贯穿于整个生育期;从吸收总量看,吸氮最多,钾次之,磷最少。

      Abstract: In order to explore the effects of formula fertilization on tomato yield, quality and the absorption rules of nitrogen, phosphorus and potassium, formula fertilization test on tomato was carried out in spring greenhouse of Yanqing. The results showed that the highest yield (13 535 kg) and excellent quality could be obtained when the application amount of nitrogen, phosphorus and potassium were 12.40, 5.28, 16.68 kg per 667 m2, respectively. There was little difference between different fertilization treatments on dry matter accumulation and nitrogen uptake in the whole growth period of tomato. Tomato uptake values of phosphorus and potassium of optimization treatment were higher than traditional treatment and control treatment. The uptake values of nitrogen, phosphorus and potassium were all high throughout the whole growth period and the maximum and minimum absorption amount belonged to nitrogen and phosphorus, respectively.
