试验结果表明,甜椒分期追施氮肥对产量效应有明显的影响。在初花期、中果期、始收期、返秧初果及中果期连续追氮增加了单株结果数和果实重量,产量最高,增长指数为167～232％;合理分期施氮增强了植株的生理活性,提高了根系吸收力和叶片叶绿素含量及光合率。试验结果为合理经济追施氮肥提供了理论依据。 The results showed that sweet pepper nitrogen application on the yield significantly affected by stage. In the early flowering stage, the mid-flowering stage, the initial stage of harvesting, the initial stage of returning seedlings and the continuous top-dressing of mid-season increased the number of fruits per plant and the weight of fruits, with the highest yield, with the growth index of 167-232% Plant physiological activity, increased root absorption and leaf chlorophyll content and photosynthetic rate. The test results provide a theoretical basis for the economic economic recovery of nitrogen fertilizer.
