| 摘 要： | 为了探究在灌溉系统中水动注入式滴灌施肥机灌水与施肥的分布特征,在整个灌溉施肥周期进行测试,对各滴头进行连续取样,并采用光度比色法作为检测肥液浓度的方法,从而分析灌水和施肥均匀性。结果表明:施肥机的灌水和施肥均匀性良好,各项统计指标均在98%以上,且各滴头的灌水流量与施肥量受滴头到支管进口与毛管进口的距离影响。

| Abstract: | In order to explore the distribution characteristics of irrigation and fertilization in the drip irrigation fertilizer applicator.In the process of fertilization,photometric colorimetry is used as a method to detect the concentration of fertilizer solution,so as to analyze the uniformity of irrigation and fertilization.The results show that the statistical indicators of the uniformity of fertilization of the fertilizer applicator are above 98%.The irrigation flow and fertilization amount of each emitter are affected by the distance from the emitter to the inlet of the branch pipe and the inlet of the capillary. |
