摘 要 ：应用通用旋转回归组合设计 ,研究了山西省石灰性褐土上施用氮、锌、锰肥对小白菜产量和品质的影响。结果表明 ,在施磷、钾肥的基础上 ,施用氮、锌、锰肥的增产效果为氮 >锌 >锰。氮与锌、锰肥配施有利于小白菜增产和改善品质。在本试验条件下 ,小白菜高产、优质施肥方案为尿素 288.2～446.4kg hm²、硫酸锌 60.8～118.9kg hm²、硫酸锰 67.5～ 127.2kg hm²。

Abstract:A field experiment was conducted to study the effect of urea, zinc sulfate and manganese sulfate combined application on yield and quality of Chinese cabbage (Brassica chinensis var.communis T.et L) in calcareous cinnamon soil of Shanxi province with the design of ordinary second order rotational regression of three factors. The results showed that under application of P and K as basal fertilizer, the effect of N, Zn, Mn on cabbage yield was N> Zn> Mn., however over N rate the yield and quality decreased sharply. Combined application of N and Zn, Mn could increased yield and improved the quality of Chinese cabbage. The optimum application rates was urea 288.2-446.4 kg/hm², zinc sulfate 60.8- 118.9kg/hm², manganese sulfate 67.5-127.2 kg/hm² under this experiment conditions.
