The utilization rate of nitrogen, phosphorus and potassium compound fertilizer is relatively low. Xue Xuefeng said that since the "11th Five-Year Plan" period, China's phosphate fertilizer has developed rapidly, and its total production capacity has reached 20 million tons, including 11 million tons of NPK fertilizer and 14 million tons of DAP. , 14 million tons of monoammonium phosphate. Compared with the end of the “10th Five-Year Plan†period, the production capacity of high-concentration phosphate and compound fertilizer increased by 90%, accounting for more than 75%; the production capacity of low-level superphosphate and calcium magnesium phosphate decreased by approximately 20%. At present, the output of phosphate fertilizer has been able to fully meet domestic demand, product structure has been greatly improved, the domestic market share has continued to increase, the industrial layout has become more rational, and the degree of industrial concentration has been greatly improved.
According to statistics from the China Phosphate Fertilizer Industry Association, from January to October this year, the production of diammonium phosphate reached 9.711 million tons, an increase of 14.9% over the same period; monoammonium phosphate was 6.964 million tons, a year-on-year increase of 14.7%; and the utilization rate of NPK fertilizer was at a relatively low level. It did not begin to recover until August. It is predicted that this year, the output of phosphate fertilizer will be 14.5 million tons, and the consumption will be 12 million tons, of which high-concentration phosphorus compound fertilizer will account for more than 75% of the total output of phosphate fertilizer. The output of diammonium phosphate will be close to 12 million tons, and the supply will be sufficient this winter and next spring.
Despite the rapid development of the phosphate compound fertilizer industry, actual use has not increased significantly. According to the analysis of the Ministry of Agriculture, in 2015, China's nitrogen fertilizer demand was 32.5 million tons, phosphorus fertilizer was 13 million tons, and potash fertilizer was 9.5 million tons, 2.5 million tons, 1 million tons, and 500,000 tons more than this year respectively; : 0.4:0.3, unchanged.
No longer to build a new expansion and expansion of ammonium phosphate project However, Xue Xuefeng pointed out that at present, China's phosphorus and compound fertilizer industry still has outstanding problems: Phosphorous compound fertilizer has excess capacity, some places are still blind development; *, potassium shortages, external dependence High degree; compared with foreign phosphorus-producing countries, China's phosphorus and compound fertilizer industry concentration is still decentralized; innovation capacity is not strong, there are few patented technologies with independent intellectual property rights; long-term dependence on policy support, industrial competitiveness is not strong; limited investment in environmental protection The comprehensive utilization of phosphogypsum lacks strong technical support on key issues.
Therefore, the “Twelfth Five-Year Plan†industry development goal proposes that the total amount of phosphate fertilizers will be controlled to prevent blind development, and no new and expanded ammonium phosphate and supporting phosphoric acid projects will be newly built and expanded within 3-5 years. At the same time, it is necessary to increase the utilization rate of middle-low grade phosphate ore, increase the degree of protection of phosphorus resources, and improve industrial concentration by optimizing resource allocation, mergers, reorganizations, and alliances. In addition, we encourage the development of new varieties of phosphate fertilizers, strengthen research on the use of low-grade phosphate rock, convert insoluble phosphorus into nutrients such as plant-absorbable nutrients, and carry out comprehensive utilization of resources.
According to the plan, in the next five years, diammonium phosphate, monoammonium phosphate, calcium superphosphate, nitrogen and phosphorus fertilizers, and phosphate-based nitrogen, phosphorus and potassium compound fertilizers will not be developed to maintain the current production capacity of general calcium phosphate and calcium magnesium phosphate fertilizers; Slow, controlled release fertilizers and various kinds of special fertilizers and functional fertilizers are suitable for drip-irrigation fertilizer raw materials for water-saving agriculture, and new types of fertilizers such as liquid fertilizers with fertilizer-water integration technology and various special fertilizers.
According to Xiu Xuefeng, the conditions for the entry of phosphoric acid and its accompanying monoammonium phosphate and diammonium phosphate projects have been formulated in accordance with conditions such as layout, technology, energy consumption, and environmental protection, and are expected to be implemented within the year; there will be no energy consumption at that time. Projects requiring environmental protection and environmental protection will be gradually phased out, and new construction and reconstruction projects will also be subject to strict restrictions. At the same time, it will gradually formulate access conditions for compound fertilizers, wet-process phosphoric acids, and superphosphates in accordance with relevant requirements; strict standards for impurities and harmful elements in phosphate and compound fertilizer products, and formulate energy consumption standards for phosphate-based compound fertilizers and calcium, magnesium and phosphate fertilizers. According to the standard of the raw materials needed for the establishment of all varieties of phosphorus and compound fertilizers, establish industry-related industrial grade monoammonium phosphate, water soluble fertilizer and other product standards.
In addition, the China Phosphatic Fertilizer Industry Association has proposed to the relevant departments to cancel the industry's preferential policies and implement a step-by-step implementation plan, and gradually cancel the preferential policies enjoyed by the industry in the order of canceling preferential electricity prices, restoring value-added tax for production processes, and canceling preferential freight rates.
It is enough to look at these points when purchasing a detachable Container House!
There are still many types of detachable container house on the market, and in addition to being used on daily construction sites, many temporary buildings such as apartments, homestays, offices, schools, dormitories, and camps are also widely used. Its construction is convenient, the investment is low, and it can be used for a long time, and the cost performance is also really good. But there are many similar container houses on the market, how should we choose? In fact, it is enough to look at the following points when purchasing a high-quality container house.
Green is very important
The structure of the container house is simple, and it can also be disassembled. Even if it is only used for a short time, it can be installed again later, which will not cause waste of materials and will not generate construction waste. And you can freely splicing and DIY to create a lot of shapes, which is very good. It is an incomparable advantage of Folding Container House and Flat Pack Container House. When choosing a detachable container house, the roof can be made of solar panel materials, so that It can provide enough electric energy for the interior of the house, and can also achieve a good environmental protection effect.
Ease of use comparison
Compared with traditional concrete buildings, the construction of detachable container houses is really convenient. You only need to determine the specific dimensions and specifications, and then you can install them immediately. Moreover, the panels only need to be assembled in order. If it is a small container house, one or two workers can quickly complete the construction. Moreover, the boards of container houses are easy to transport. Even if the house has been built, it can be disassembled and transported directly in the later stage, and it is very convenient to use in different positions.
Cost-effective comparison
Since it is necessary to purchase a detachable container house, it is still necessary to measure the price. On the one hand, it is necessary to determine the quality of its materials and whether it can meet the standard of long-term use. On the other hand, it is also necessary to measure the price. Generally, manufacturers quote according to the specific size and area of the container house and the material of the color steel plate, so it is still necessary to make a comprehensive comparison, so that it is also very simple to choose a cost-effective container house.
