豆科作物具有自身固氮的功能。因而人们在豆科作物的栽培中,很少甚至根本不施氮肥。针对这种情况,我们以大豆为试验材料,以玉米、谷子、高粱为配合材料,进行了固氮与非固氮作物追施氮肥效果的对比试验。四次重复,结果如下:
Legume crops have their own nitrogen fixation function. Therefore, people in the cultivation of leguminous crops, little or no nitrogen fertilizer. In response to this situation, we use soybeans as test materials, with maize, millet, sorghum as the mating material, nitrogen and nitrogen-fixing crops were topdressing nitrogen fertilizer effect comparison test. Repeat four times, the result is as follows:
