试验采用蔓生型绿豆辽绿6号为试材,美国磷酸二铵:①高肥(225 kg/hm2)、②中肥(150kg/hm2)、③不施肥3个处理。小区面积15 m2,随机区组排列,3次重复。该试验分析了磷酸二铵对蔓生型绿豆辽绿6号产量的影响及氮磷钾在茎秆、叶片中积累的规律。试验结果表明:高肥处理有利于绿豆氮磷钾三元素的积累;中肥处理有利于绿豆株荚数、株粒数、株粒重的增加及产量的提高;辽绿6号在中肥处理(磷酸二铵150 kg/hm2)的情况下,产量最高,比对照增加产量472.5 kg/hm2,说明中肥处理有利于辽绿6号产量的提高。
The experiment was conducted with the vine-grown mung bean Liaolu 6 as test material and the American diammonium phosphate: ① high fertilizer (225 kg / hm2), ② medium fertilizer (150kg / hm2), ③ no fertilizer 3 treatments. District area of 15 m2, random block arrangement, 3 repetitions. The experiment analyzed the impact of DAP on the yield of vine-yielding mung bean Liaokong 6 and the accumulation of NPK in stems and leaves. The results showed that the treatment with high fertilizer was beneficial to the accumulation of three elements of NPK in mung bean. The treatment with medium and fertilizer was beneficial to the increase of pods, the number of grains per plant, the grain weight and the yield of mung bean. (Diammonium phosphate 150 kg / hm2), the yield was the highest, which increased by 472.5 kg / hm2 compared with the control, indicating that medium-fertilizer treatment was beneficial to the increase of Liaolu 6 yield.
