不少研究者采用根外喷肥方法提高了尿素、磷酸二氢钾以及各种微量元素肥料的利用率,而用高浓度三元复合肥作根外追肥的报道甚少。为此我们选用重庆川江化工厂试制的高浓度三元复合肥磷酸二氢钾铵和含硼磷酸钾铵对玉米进行根外喷施试验,以考察其对玉米产量和品质的影响,为在玉米生产上推广应用这两种复合肥提供科学依据。
Many researchers use root-outside spraying method to improve the utilization rate of urea, potassium dihydrogen phosphate and various trace element fertilizers. However, there are few reports about top-dressing with high-concentration ternary compound fertilizer. To this end, we use the trial of Chongqing Chuanjiang Chemical Plant trial of high concentrations of tribasic compound fertilizer potassium dihydrogen phosphate and potassium ammonium borophosphate containing corn root spray test to investigate its yield and quality of corn, in order to corn Production and promotion of these two kinds of compound fertilizer to provide a scientific basis.
