豆科作物在轮作制度中占有重要地位.将它纳入轮作中并结合有关技术措施,可以实现用地与养地相结合,建立起高产优质低消耗的农田生态系统.据报道,全世界豆科作物每年的固氮量相当于工业固氮量的3.8倍,占固氮总量的79.3%,且豆科作物固氮比工业固氮优越得多.近年来,世界各国十分重视对豆科作物固氮作用的研究,大豆根瘤菌肥料的应用就是其中之一.塔城地区的耕地普遍缺氮少磷,土壤肥力急待提高.为了提高土壤肥力,同时满足人民对豆制品的需要,塔城地区逐年扩大大豆种植面积,但由于栽培大豆的历史不长,土
Legume crops play an important role in the rotation system.It is included in the rotation and combined with the relevant technical measures, can be achieved with the combination of land and raised land, to establish high-yielding high-quality low-consumption farmland ecosystem.It is reported that the world leguminous crops The amount of nitrogen fixation per year is equivalent to 3.8 times of that of industrial nitrogen fixation, accounting for 79.3% of the total nitrogen fixation, and the nitrogen fixation of leguminous crops is much better than that of industrial nitrogen fixation.In recent years, many countries in the world attach great importance to nitrogen fixation of leguminous crops, The application of rhizobium fertilizer is one of them.Cultivated land in Tacheng is generally deficient in nitrogen and phosphorus and soil fertility is urgently needed to be improved.In order to improve soil fertility and meet people’s demand for soy products, However, due to the history of cultivated soybean is not long, soil
