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. |
