摘要
在多年多点田间试验条件下,研究大白菜产量与氮肥用量间的关系,建立不同地区的大白菜氮肥效应函数模型。研究表明：辽宁省大白菜合理氮肥推荐用量为199.17~278.36 kg/hm^2,在此范围内大白菜有望获得最高产。
In the article, it studied the relationship between Chinese cabbage yield and nitrogen fertilizer applying amount under the conditions of field tests in many points of many years, set up models of Chinese cabbage nitrogen fertilizer effect in different regions. The result showed that the recommended amount of nitrogen fertilizer for Chinese cabbage of Liaoning province is 199.17~278.36 kg/hm^2,it has big possibilities of obtaining highest yield within this range.
