河南是我国复大豆主要产区,常年种植面积1300—1500万亩,但产量水平较低,亩产只有60多公斤。除大量元素之外,微量元素供应不足是影响产量提高的因素之一。硼、铝、锰、铜、锌等是多种酶的组成成分,是作物正常生长发育所必须的营养元素,而且大豆又是对钼、锌、锰微量元素缺乏很敏感的一种作物。由于我省大豆产区土壤微量元素的含量偏低,因此施用微量元素肥料将是进一步提高大豆产量和共生固氮率,改进品质
Henan is the main producing areas of China’s complex soybean, perennial planted area of 1300-1500 acres, but the yield level is low, only 60 kilograms per mu. In addition to a large number of elements, the lack of supply of trace elements is one of the factors that affect the yield increase. Boron, aluminum, manganese, copper and zinc are the components of many kinds of enzymes, which are necessary nutrients for the normal growth and development of crops, and soybean is also a sensitive crop to the lack of trace elements of molybdenum, zinc and manganese. Due to the low content of soil trace elements in the soybean producing areas in our province, the application of trace element fertilizers will be to further increase soybean yield and symbiotic nitrogen fixation rate, improve quality
