不同钾肥施用量对樱桃番茄产量与品质的影响
Effects of Different Potassium Fertilizer Application Rates on Yield and Quality of Cherry Tomatoes
摘要
Abstract
In order to reduce the application rate of potassium fertilizer in cherry tomato cultivation,Mengxiang Zhentian No.2 was taken as the research object,and 5 treatments of K2O application rates[330.0,300.0(conventional application rate of farmers),270.0,240.0 and 210.0 kg/hm2]were set up to carry out the field experiment(application rates of nitrogen and phosphorus fertilizers for each treatment were the same).In this experiment,we compared the effects of different K2O application rates on the growth,quality and yield of cherry tomato.The results showed that compared with the conventional application rate of farmers,when the K2O application rate was 270.0 kg/hm2(the application rate of K2O decreased by 10%),the equivalent yield of cherry tomatoes increased by 4.26%,resulting in an increase of 2 431.75 kg/hm2.Additionally,the quality of cherry tomatoes was optimal,with the highest levels of VC content(381 mg/kg),soluble solids content(11.7%),soluble sugar content(5.61%),titratable acid content(0.67%),sugar acid ratio(8.37),lycopene content(351.26 μg/g),and hardness(6.25 kg/cm2)of cherry tomato fruit.关键词
