我国东北平原黑土带是世界三大黑土带之一,东北地区特有的土壤、气候条件非常适合大豆、玉米、水稻、马铃薯等农作物的种植,因此东北地区成为我国的粮食主产区和重要商品粮基地,仅黑龙江的大豆产量就占全国产量的40%左右。而近年来,由于气温多变,干旱和内涝问题频现,如何把握好从种到收各个环节的管理成为保证大豆增产丰收的关键。作者经过多年的积累,借鉴其他专家的文献和研究成果,通过本文归纳了常见气候条件下大豆春节播种前后应该注意的问题,以保证大豆产量的增加以及品质的保障和提升。
China’s northeast plain black soil zone is one of the three major black soil zones in the world. The soil and climatic conditions in northeast China are very suitable for the cultivation of crops such as soybean, corn, rice and potato. Therefore, Northeast China has become the major grain producing area and important commodity grain base in China Only Heilongjiang’s soybean output accounts for about 40% of the national output. In recent years, due to the ever-changing temperature and the frequent occurrence of drought and waterlogging problems, how to grasp the management from all walks of life to various links has become the key to ensuring the yield increase of soybean. After years of accumulation, the author draws on the literature and research results of other experts, summarizes the issues that should be paid attention to before and after sowing of Chinese New Year under common climatic conditions in order to ensure the increase of soybean yield and the guarantee and improvement of quality.
