摘要:
当前东北地区农业生产面临严重的生态环境挑战，在此背景下，该研究利用轮作定位试验和农户调研数据，从两个层面对粮豆轮作技术的“减肥增效”效应展开实证分析。研究结果显示：与已有研究一致，粮豆轮作能够增加玉米和大豆单产，减少大豆农药施用量和玉米化肥施用量。其中，和非轮作相比，轮作的大豆产量高325.65 kg·hm-2，玉米产量高803.81 kg·hm-2，节省大豆农药投入费用42 元·hm-2，节省玉米化肥投入量117 kg·hm-2。总体而言粮豆轮作技术具有“减肥增效”的生态效应。该研究结果为推广粮豆轮作技术和制定合理的轮作补贴标准提供了科学依据。
Abstract:
At present, the agricultural production in Northeast China is facing serious ecological problems.In this background, this paper used the rotation experiment and farmers′ survey data to empirically analyze the effect of reducing fertilizer input and increasing efficiency of grain-soybean rotation technology from two aspects. The results indicated that: Consistent with existing studies, grain-soybean rotation technology could increase the yield of maize and soybean, reducing the amount of soybean pesticides and maize fertilizer use. In particular, the soybean yield of the rotation was 325.65 kg·ha-1 higher than that of the non-rotation，and the maize yield was 803.81 kg·ha-1 higher. In addition, the rotation saved 42 yuan·ha-1 for soybean pesticides and 117 kg·ha-1 for maize fertilizers. In general, there is indeed an ecological function of reducing fertilizer input and increasing efficiency in grain-soybean rotation technology. The research in this paper provided a scientific basis for promoting the adoption of grain-soybean rotation technology and establishing a reasonable rotation technology subside standard.
