摘要
【目的】研究施用不同量磷肥对膜下滴灌加工番茄产量、品质及磷肥利用率的影响。【方法】以金番1606加工番茄为供试品种,通过田间试验,在相同氮钾(N 240 kg/hm^(2)、K_(2)O 90 kg/hm^(2))的基础上,设5个处理:(1)P 0:不施磷肥;(2)P_(60):磷肥(P _(2) O _(5))用量为60 kg/hm^(2);(3)P_(120):磷肥(P _(2) O _(5))用量为120 kg/hm^(2);(4)P_(180):磷肥(P _(2) O _(5))用量为180 kg/hm^(2);(5)P_(240):磷肥(P _(2) O _(5))用量为240 kg/hm^(2)。【结果】与不施磷肥处理相比,施用磷肥显著提高了加工番茄的磷素吸收量,且P吸收速率随施磷量的增加而增加,但磷肥的利用效率却随施磷量的增加而降低。施用磷肥显著增加了加工番茄产量,比不施磷肥增产3.6%~7.4%,当磷肥用量小于120 kg/hm^(2)时,加工番茄产量随施磷量的增加而增加;当磷肥用量超过120 kg/hm^(2)时,加工番茄的产量不再显著增加。而施用磷肥对加工番茄品质没有显著影响。【结论】最佳经济施磷量为129.7 kg/hm^(2),最佳经济产量为121 t/hm^(2)。
【Objective】To study the effects of applying different amounts of phosphate fertilizer on the yield.【Method】Phosphorus utilization efficiency of tomato under drip irrigation using Jinfan 1606 processed tomato as a test variety through field experiments.Based on the same nitrogen and potassium(N 240 kg/hm^(2),K_(2)O 90 kg/hm^(2)),five treatments were set up in the test:(1)P 0:no phosphate fertilizer was applied;(2)P_(60):phosphate fertilizer(P _(2) O _(5))was used at 60 kg/hm^(2);(3)P_(120):phosphate fertilizer(P _(2) O _(5))is 120 kg/hm^(2);(4)P_(180):phosphate fertilizer(P _(2) O _(5))is 180 kg/hm^(2);(5)P_(240):phosphate fertilizer(P _(2) O _(5))is 240 kg/hm^(2).【Result】The results showed that compared with the treatment without phosphorus fertilizer,the application of phosphorus fertilizer significantly increased the phosphorus absorption of processed tomatoes,and the P absorption rate increased with the increase of phosphorus application,but the utilization efficiency of phosphate fertilizer decreased with the increase of phosphorus application.At the same time,the application of phosphate fertilizer significantly increased the yield of processed tomatoes,which increased 3.6%-7.4%compared with no phosphate fertilizer.When the amount of phosphate fertilizer was less than 120 kg/hm^(2),the yield of processing tomatoes increased with the increase of phosphorus application;and when the amount was over than that,the yield no longer increased significantly.The application of phosphate fertilizer had no significant effect on the quality of processing tomatoes.【Conclusion】Under this experimental condition,the suitable phosphorus application rate was 129.7 kg/hm^(2),and the optimal economic yield was 121 t/hm^(2).
