黑龙江省是国家的大豆主产区。占全国大豆总播种面积的50％以上,随着播种面积的增加,使大豆产区重迎茬面积不断扩大,特别是豆、麦、豆轮作区重迎茬面积更大。有些耕地重迎茬长达9—10年,出现了土壤营养单一、养分失调。这给专用化肥厂研制生产农作物高产专用肥提出了急待解决的课题。为此,大龙专用化肥厂与科研部门紧密合作,通过招聘人才、购买专利等措施,生产出TPV大豆重迎茬专用肥、颗粒钾系列和专用肥系列等11个新肥种上万吨,为发展农业生产作出了显著的贡献,同时也使企业得到发展。 一、研制适用于机械化施用的新肥种。自1994年起,我厂结合黑龙江省大型农场多、豆麦产区集中的实际情况,研制生产颗粒强度高、粒型整齐一致、
Heilongjiang Province is the country’s main soybean producing area. It accounted for more than 50% of the total sown area of soybean in China. With the increase in sown area, the soybean production area continues to expand, especially for beans, wheat and beans. Some arable lands have been welcoming for 9-10 years. There is a single nutrient in the soil and nutrient imbalance. This raises urgent issues for special fertilizer plants to develop and produce special fertilizers for crops with high yields. To this end, Dalong Special Fertilizer Factory cooperates closely with the scientific research department, and through the recruitment of talents, purchase of patents and other measures, it has produced 10,000 tons of 11 new fertilizers such as TPV Soybean Recycling Special Fertilizer, Granule Potassium Series and Special Fertilizer Series. It has made significant contributions to the development of agricultural production, and at the same time it has also allowed businesses to develop. First, develop new fertilizers suitable for mechanized application. Since 1994, our company has developed and produced high-strength pellets and uniform and consistent pellets in combination with the fact that many large-scale farms and soybean-producing areas are concentrated in Heilongjiang Province.
