| 摘 要： | 对大田种植小麦追施不同种类及不同用量尿素进行研究,结果表明,追施普通尿素和大颗粒尿素有利于作物吸收,叶绿素含量高;硫包衣尿素速效性差,但是缓释作用明显,在小麦生长中后期增加群体叶面积系数,提高收获穗数和千粒重,生产中可考虑做基肥施用;同时不同种类尿素也可搭配施用,以提高肥料利用率。

| Abstract: | A study was made on the effects of application of different kinds and different amounts of urea on the growth and development of wheat on open field. The result showed that the topdressing of common urea and large particle urea were beneficial to the plant＇s absorption of nitrogen and the chlorophyll content was higher. The sulfur-coated urea had a weak quickly releasing effect, but the slow-release effect was significant. The topdressing of sulfur-coated urea could increase population leaf area index and the number of spike and 1 000-grain weight in the middle-later period. In production,the sulfur-coated urea should be used as base fertilizer mixed with different kinds of urea to improve fertilizer use efficiency. |
