摘要
研究了树脂包膜尿素对温室番茄产量及品质的影响,结果表明:与普通尿素相比,包膜尿素可降低番茄畸形果率及NO3--N含量,提高了糖/酸比;树脂包膜尿素CU 可明显提高番茄vC含量;CUI和CUII有一定的增产作用,CUI减量15%施用,不减产;二者各半量混用,番茄产量得到进一步提高。
Compared with common urea, the effects of resin-coated urea ,CUI、CUII, on the yield and quality of sunlight greenhouse tomato were tested ,the results showed that CUI can increase vC content in the fruit; CUⅠ、CUⅡ can improve sugar-acid ratio of tomato fruits, and remarkably reduce abnormal fruits and NO_3^--N level in fruits. 85% of CUI didn′t decrease the output,50% CUI and 50% CUII led further to increase yield.
