摘要
在氮、磷、钾配方施肥的基础上，采用田间试验的方法，研究了山西省石灰性褐土上锰对小白菜（brassica campestris ssp．chinensis）产量和品质的影响。结果表明，适量增施锰肥，能显著提高小白菜的产量和品质，与对照不施锰肥相比，小白菜增产5．5～15．1％，Vc、可溶性糖含量分别提高29．5～55．1％和6．4～18．7％，硝酸盐含量降低5．2～8．9％。在每hm^2土壤施用尿素400kg，过磷酸钙200kg，硫酸钾200kg条件下，得出小白菜高产、优质的施肥量为硫酸锰30～75kg／hm^2。
In order to establish a reasonable Manganese fertilizer proportional scheme and to improve the yield and quality, a field experiment was conducted on calcareous cinnamon soil of Shanxi Province to study the effects of Manganese fertilizer on yield and quality of Chinese cabbage （Brassica campestris ssp. chinensis） based on the N, P, K prescription fertilization. The results showed that application appropriate Manganese fertilizer could increase the yield and quality of Chinese cabbage remarkably. Adding the Manganese fertilizer, the yield and content of Vc, Dissoluble sugar increase by 5. 5- 15. 1%, 29. 5-55. 1%, 6. 4-18. 7%, respectively, and nitrate content decrease by 5. 2- 8. 9%. For the higher yield and better quality Chinese cabbage, the optimum applied amount of Manganese sulfate was 30 - 75 kg/hm^2, considering the applied rates of N, P and K were urea 400kg/ hm^2, single super phosphate 200 kg/hm^2, potassium sulphate 200 kg/hm^2.
