Effects of Zinc on the Yield and Quality of Chinese Cabbage

在氮、磷、钾配方施肥的基础上,研究了山西省石灰性褐土上施锌对小白菜产量和品质的影响。结果表明:施用锌肥不仅能提高小白菜的产量,而且有利于品质的改善。在每公顷土壤施用尿素361.52kg、过磷酸钙102.33kg、硫酸钾198.27kg条件下,得出小白菜高产、优质的硫酸锌施用量为75￣120kg/hm2。

A field experiment was conducted on calcareous cinnamon soil of Shanxi Province to study the effects of zinc fertilizer on yield and quality of Chinese cabbage. The results showed that application Zinc fertilizer could increase the yield and quality of Chinese cabbage on the basis of combined application of N, P and K. The optimum amount of zinc sulfate application was 75-120 kg/hm^2 when the -application rates of N, P and K were urea 361.52kg/hm^2, ordinary superphosphate 102.33kg/hm^2, potassium sulphate 198.27 kg/hm^2.
