2006年在北京市顺义区布置了糯玉米肥料效应试验,研究氮磷钾的不同配比对糯玉米产量和养分吸收的影响,确定当地糯玉米的氮磷钾适宜施用量。采用“3414”部分实施设计,3次重复,完全随机区组设计。试验结果表明,处理3(N1P2K2)纯收入为19594元/hm2,是所有处理组合中最高的,为最佳施肥组合。不同施肥处理对糯玉米籽粒中的养分含量影响不大,但对糯玉米秸秆中的养分含量影响较大。在本试验条件下,氮肥和磷肥的推荐用量应保持在中等水平,而钾肥的增产作用不明显。该地区糯玉米生产的氮、磷肥推荐用量分别为120kg N/hm2和90kg K2O/hm2。
In 2006, Shunyi District of Beijing arranged waxy corn fertilizer effect experiments to study the different proportion of NPK on waxy corn yield and nutrient absorption, to determine the local waxy corn NPK suitable application. The “3414” part of the implementation of the design, 3 repetitions, completely random block design. The results showed that the net income of treatment 3 (N1P2K2) was 19,594 yuan / hm2, which was the highest among all treatment combinations and was the best combination of fertilization. Different fertilization treatments have little effect on the nutrient content of waxy corn, but have a greater impact on the nutrient content of waxy corn straw. Under the test conditions, the recommended dosage of nitrogenous fertilizer and phosphate fertilizer should be maintained at a medium level, but the yield-increasing effect of potassium fertilizer is not obvious. The recommended production of nitrogen and phosphate fertilizers for waxy maize in this area are 120kg N / hm2 and 90kg K2O / hm2, respectively.
