On April 12, the science and technology award conference of Hebei Province was held in Shijiazhuang, Hebei Province. In 2021, there were 259 science and technology awards in Hebei Province. Among them, Hebei Monband water-soluble fertilizer Co., Ltd. won the first prize of the science and Technology Progress Award for the improvement of cultivated land quality and precision management technology of nutrients in the main grain producing areas of Hebei Province, and the organic fertilizer efficiency mechanism and precision management technology of fertilizer and water in protected vegetable fields won the second prize of the science and technology progress award.

Guard the "grain bag" to develop and promote new fertilizers

Hebei is one of the ten major grain producing provinces in China. It is reported that the main grain producing areas in Hebei are mainly distributed in the piedmont plain and the low plain. The annual planting area is about 75 million mu, and the grain output accounts for 87% of the province. For a long time, the partial application of chemical fertilizer and light application of organic fertilizer have caused the imbalance of soil nutrients, the decline of buffering capacity and the low fertilizer efficiency, which pose a threat to the implementation of the strategy of "storing grain in the land".

With the support of national and provincial projects, the project team composed of relevant staff from the agricultural resources and Environment Research Institute of Hebei Academy of agricultural and Forestry Sciences, Hebei cultivated land quality monitoring and Protection Center, Hebei Agricultural Technology Promotion general station, and Hebei mengbang water-soluble fertilizer Co., Ltd. has, through several years of research, found out the regional distribution status of fertility factors, revealed the evolution law of soil fertility over the past 40 years, and innovated the principle of nutrient regulation, In addition, the improvement parameters of fertility factors and their effects on crop yield were put forward for the first time, and the minimum objective of regional fertilization and the limited standard of fertilization were defined. It has created 4 technologies and products to improve the quality of arable land. It integrates the comprehensive technology mode of cultivated land quality improvement and nutrient precision management.

In the past three years, the project team has promoted a total of 75.473 million mu, increased soil organic matter by 0.50 g / kg, increased fertilizer utilization rate by 5.6%, increased grain production by 960 million kg, and added a total output value of 2.516 billion yuan. He published two monographs, 38 papers, 5 authorized patents (2 invention patents), 12 software copyrights, and 1 local standard, providing technical support for soil health and green production, with remarkable economic, social and ecological benefits. According to the evaluation of academicians and other experts, the overall achievements have reached the international leading level of similar research.

Hebei Monband water-soluble fertilizer Co., Ltd., as the project participant, participated in the research and development, production and technology promotion and demonstration of the liquid compound fertilizer based on urea ammonium nitrate solution, developed three new water-soluble fertilizers for wheat and corn, formulated one enterprise standard, and applied them in Handan, Xingtai, Hengshui, Cangzhou and other places, making important contributions to the technology and products for improving the quality of arable land.

Enrich the "vegetable basket" and explore and promote good products and new technologies

Protected vegetables are the dominant and characteristic industries in Hebei Province. At present, the excessive use of fertilizers and the serious degradation of soil quality restrict the green and sustainable production of vegetables. Relying on the national Bulk vegetable industry system, the Ministry of agriculture's public welfare industry plan and other projects, the project team of organic fertilizer efficiency enhancement mechanism and fertilizer and water precision management technology in protected vegetable fields composed of the Institute of agricultural resources and environment of Hebei Academy of agricultural and Forestry Sciences, the Institute of agricultural resources and agricultural regionalization of the Chinese Academy of Agricultural Sciences and Hebei mengbang water soluble fertilizer Co., Ltd. has completed more than 10 years of long-term positioning tests and multi-point experimental demonstration studies, Taking the substitution of organic fertilizer for part of chemical fertilizer as a breakthrough point, we have thoroughly revealed the efficiency increasing mechanism of organic fertilizer for chemical fertilizer, created a simple and quick recommendation method for fertilizer amount that is easy for users to grasp, created a new type of drip irrigation special fertilizer product, and innovated and integrated integrated integrated integrated organic substitution comprehensive efficiency, balanced application of large, medium and small elements, and integrated precision management technology for fertilizer and water, thus realizing the reduction of chemical fertilizer, soil improvement, and improvement of vegetable quality and efficiency.

It is reported that during the project, the team completed 8 national invention patents, 3 registered software copyrights, 3 industrial / provincial local standards, 53 papers (11 included in SCI), and 1 monograph. The core technology was selected as the main agricultural technology in Hebei Province. In the past three years, 4.49 million mu of fertilizer has been popularized and applied in Hebei Province and its surrounding areas, 34.1% of the fertilizer nutrients have been reduced, 8.4% of the output has been increased, 2249 yuan has been increased per mu, the accumulated new output value is 6.37 billion yuan, the total savings is 3.084 billion yuan, and the new profit is 9.454 billion yuan. This achievement has strong technical innovation, high degree of achievement transformation, and significant economic, social and ecological benefits. It has a major supporting role for the green development of the protected vegetable industry. After evaluation by academicians and expert groups, it has reached the international leading level of similar research.

Hebei Monband water-soluble fertilizer Co., Ltd. is the main promotion unit of the project. Taking the project achievements as an opportunity, it constantly promotes the development of fertilizer reduction and efficiency increase, explores more experiences and models that can be popularized and replicated, and promotes the green development of protected vegetables.
