摘　　要：以番茄无限生长型新组合09-12杂种种子为试材,研究了叶面喷施不同浓度的钾肥对杂交番茄生长的影响。结果表明:叶面喷施钾肥的各处理,其平均结果数、单果重、单果种子数、单株产量和小区产量等指标均高于其它处理,当叶面喷施钾肥浓度为0.2%时,其产量最高,可达35.0kg/667m2,各处理对杂交番茄产量的影响效应为:A3>A4>A2>A5>A1。With indeterminate growth tomato of new combination 09-12 hybrid seed as test materials, different concentration of potash fertilizer for foliar spraying on the influence of hybrid tomato growth were studied. The results showed that the average fruits number,weight, simple fruit seed numbers and yield per plant prominently and plot yield etc index were higher than other processing after foliage spraying potash fertilize,when foliage Spraying potash fertilizer concentration was 0. 2% ,the highest yield could reach 35. 0 kg/667m2 ,each treatment effect on the production of hybrid tomato was A3〉A4〉A2〉A5〉A1.
