施用不同剂量缓释肥对盆栽樱桃番茄生长的影响

Effect of Different Dosage of Slow Release Fertilizer on Yield of Potted Tomato

[目的]采用盆栽方式研究不同缓释肥剂量对樱桃番茄生长及产量的影响。[方法]共设置5个缓释肥处理水平,分别为0 g/盆(CK)、5 g/盆、10 g/盆、15 g/盆、20 g/盆,调查不同缓释肥施用水平对樱桃番茄生长及结果特征的影响。[结果]施用缓释肥可显著增加植株高度,增加坐果数,提高单株产量,显著增加番茄果实中可溶性糖、可滴定酸含量。[结论]在该试验条件下,缓释肥建议施用量为20 g/盆。

[Objective]This work was to determine the effects of different dosage of slow release fertilizer on the growth and fruit of cherry tomato were studied by pot experiment.[Method]In the experiment,five slow release fertilizer were set up,which were 0 g/pot(CK),5 g/pot,10 g/pot,15 g/pot and 20 g/pot,respectively.The plant growth and fruit characteristics of cherry tomato were investigated.[Result]The application of slow release fertilizer could promote growth of tomato plant,increase fruit number and yield,increase soluble sugar content and titratable acid content.[Conclusion]The recommended application dosage of slow release fertilizer was 20 g/pot in this test.
