不同浓度钾肥对无土栽培樱桃番茄品质和产量的影响

探索了不同钾含量富万钾有机液肥对樱桃番茄生长发育、品质及产量的影响。试验结果表明,樱桃番茄的各项营养生长指标和钾肥用量之间都呈现出明显的正相关关系;施用钾肥能改善樱桃番茄的品质,提高VC、还原糖、可溶性固形物的含量,对总酸的含量影响不大;适量施用钾肥能起到增产作用,钾肥的不足或过多都会降低樱桃番茄的坐果率和产量。

Effects of Potassium Fertilizer with Different Concentrations on Growth, Quality and Yield of Cherry Tomatoes under Soilless Cultivation Conditions

In the paper,we studied the effects of Fuwanjia organic fertilizer with different concentrations on the growth,quality and yield of cherry tomatoes.The results showed that,there were positive correlation relationships between the application amount of potassium fertilizer and vegetative growth indexes,and the application of potassium fertilizer could improve the quality of cherry tomatoes,and increased the contents of vitamin C,reducing sugar and soluble solids,but it had little effect on the total acid content.The appropriate amount of potassium fertilizer could increase the yield of cherry tomatoes,but the inappropriate amount would reduce the fruit setting rate and yield of cherry tomatoes.
