摘 要:利用盆栽植株研究了不同形态氮肥处理对樱桃生长发育的影响。结果表明,3种形态氮肥均能促进根系生长,其中以硫酸铵效果最显著,但3种氮肥对细根中不同养分的含量影响效应不同;施用尿素对植株地上部分营养生长的促进效应好于硫酸铵和硝酸钾处理,而施用硝酸钾对植株地上部分生殖发育的促进效应好于尿素和硫酸铵处理。Effects of different nitrogen fertilizers on growth and development of cherry were studied by potted plants. The results indicated that:3 nitrogen fertilizers promoted the growth of roots, and among them the effects of ammonium sulphate were the most significant. However, effects of 3 nitrogen fertilizers on contents of nutrients in fine roots were different. Promotion effects of fertilizing with urea on nutritional growth of above- ground parts for plants were better than that treated with ammonium sulphate and potassium nitrate, and promotion effects of fertilizing with potassium nitrate on reproductive growth of above - ground parts for plants were better than that treated with urea and ammonium sulphate.
