According to the latest statistics released by the National Bureau of Statistics, China produced a total of 5.091 million tons of chemical fertilizers in June, which was down by 3.3% year-on-year. This was the first month of decline in production in the first half of this year, and the decline in fertilizer output slowed down. . In the first half of this year, China’s cumulative production of chemical fertilizers was 26.363 million tons, down 6.5% year-on-year.

Judging from the monthly output of chemical fertilizers, the first quarter was affected by factors such as tight natural gas supply, and the output declined greatly, with a monthly decline of 13.5%. After the second quarter, the supply of raw materials improved. In addition, the price of fertilizers was higher this year. The production enthusiasm was high and the output rebounded. However, due to environmental pressure, the overall output was still lower than the same period last year.

Potassium fertilizer, nitrogen fertilizer, phosphate fertilizer production continued to fall, who fell the most?

In terms of varieties, potash is the best variety produced this year and the only one with positive growth. In the first half of this year, China’s cumulative production of potassium fertilizer was 2.893 million tons, a year-on-year increase of 2.9%. Qinghai’s output was the first. In the first half of the year, it produced 1.914 million tons of potash, down 1.2% year-on-year; Xinjiang’s output was second, and cumulative production of potash in the first half of the year was 584,000 tons, up 2.9% year-on-year.

Nitrogen and phosphate fertilizer production both fell, and phosphate fertilizer production fell relatively small. In the first half of the year, China’s cumulative production of phosphate fertilizer was 6.772 million tons, a year-on-year decrease of 5.9%. Among them, Guizhou produced a total of 1.771 million tons of phosphate fertilizer, a year-on-year increase of 1.5%, surpassing Hubei ranked first. Hubei produced a total of 1.701 million tons of phosphate fertilizer, down 7% year-on-year, ranking second.

Potassium fertilizer, nitrogen fertilizer, phosphate fertilizer production continued to fall, who fell the most?

Nitrogen fertilizer production declined the most. In the first half of this year, China’s cumulative production of nitrogen fertilizer was 18.879 million tons, down 7.5% year-on-year. The top five provinces in terms of output are Henan, Inner Mongolia, Shandong, Hubei, and Shanxi, with output of 2.293 million tons, 2.122 million tons, 2 million tons, 1.805 million tons, and 1.794 million tons, up 0.5% year-on-year and down 5.4%. Growth was 2.5%, a decrease of 7.9%, and a decrease of 5.9%.

The Biodegradable Plastic Straw PHA Research Group, comprised of researchers from Georgia University (UGA), graduate students and renowned alumni, collaborated with the RWDC Foundation to synthesize a food grade polymer that will be used to develop a commercial A viable straw raw material. The development of biodegradable plastics is related to awards from the Temasek Eco Foundation in Singapore. The $71,000 award is the highest award in the first Life Ability Challenge and was awarded to RWDC Industries in Singapore in July.

RWDC and the New Materials Institute will develop prototypes to demonstrate that straw production capacity meets global demand and is fully biodegradable in soil, freshwater and seawater. Most of the testing will be conducted at the RWDC-funded Foundation’s New Materials Research Laboratory.

The plastics are made from a plant-based material called polylactic acid (PLA), which is labeled “biodegradable plastics” and can be composted in a limited environment, but they are not completely degraded. Polylactic acid is a new type of bio-based and renewable biodegradable material made from starch raw materials proposed by renewable plant resources. The starch raw material is obtained by saccharification to obtain glucose, and then glucose and a certain strain are fermented to produce high-purity lactic acid, and then a certain molecular weight polylactic acid is synthesized by chemical synthesis. It has good biodegradability. After use, it can be completely degraded by microorganisms in nature under certain conditions, and finally produces carbon dioxide and water, which does not pollute the environment. This is very beneficial to the environment and is recognized as an environmentally friendly material.

Jason Rocklin, director of the Institute of New Materials, professor of chemistry at the Franklin College of Arts and Sciences, and head of the School of Engineering, said: “Plastics made from PLA can only be degraded in industrial composting environments at high temperatures. Other types of plastics are based on petroleum. Foundation, the recovery rate of these plastics is less than 10%. Non-renewable 90% of the material will eventually break over time, and the remaining plastic as micronized will remain in the soil, rivers and oceans forever.

The competition requires students to have a solid foundation in science, innovative spirit, willing to invest time to complete the project, excellent English and good cooperation. The theme of the 2017-2018 season was to design an unmanned aerial vehicle system that accurately sprays pests and diseases that occur randomly in a designated area of cornfields and develops a business plan for the commercial operation of the system. RWDC encourages students to combine business acumen, problem-solving skills and leadership development to learn critical thinking so they can better understand the job skills required for this fast-paced, ever-changing society.

According to the business community monitoring: on August 23, the domestic price of 27.5% hydrogen peroxide was raised again. The average market price was 1,138 yuan / ton, a daily increase of 1.22%, up 3.27% from the beginning of the week.

The rising market is mainly concentrated in Hebei and Shandong, and the performance in Anhui and other regions is relatively stable. Hebei Zhengyuan offer 950 yuan / ton, daily increase of 50 yuan / ton; Hebei Xinhua offer 920 yuan / ton, daily increase of 20 yuan / ton; Shandong Haineng offer 980 yuan / ton, daily increase of 70 yuan / ton; Shandong Hengtong The price is 1,000 yuan / ton, the daily increase is 40 yuan / ton; Shandong Huatai offer 960 yuan / ton, the daily increase of 20 yuan / ton; Shandong Mingshui offer 920 yuan / ton, the daily increase of 20 yuan / ton. The mainstream price in Anhui is 1100-1200 yuan/ton, and the price is stable. The mainstream price in Zhejiang is 1,300 yuan / ton, holding steady.

The hydrogen peroxide analyst of the business community believes that: in late August, the hydrogen peroxide manufacturers in the northern region have raised their prices, and the southern region is relatively stable. This is because the traditional consumption season is approaching, and the south market may usher in a rising tide. The hydrogen peroxide market is easy to rise and fall.

Xinhua News Agency, Xining, August 22 (Reporter Luo Xiaofei, Deng Wanli) After 60 years of development and construction, China’s potash industry has been expanding, from relying entirely on imports to the current self-sufficiency rate of nearly 60%, greatly enhancing the right to speak in the international potash market and promoting China’s food production.

This is what the reporter learned from the 2018 Potash Potash Conference and the Golmud Salt Lake Forum on the 21st. Potassium is one of the three major nutrient fertilizers for crops, and plays a pivotal role in ensuring agricultural production and food security. China is a country with potassium deficiency, and its resource reserves only account for about 2% of the world.

It is understood that China’s proven resource reserves are mainly in the Salt Lake Potash Mine, mainly distributed in the Qaidam Basin of Qinghai and the Lop Nur area of Xinjiang. With the completion of the two major potash bases, especially in the past ten years, China has broken through the low-grade solid potassium salt, tailings utilization, deep brine mining and other technologies, so that the potassium salt can be multiplied.

It is located in Chaerhan Salt Lake, Golmud City, Haixi Mongolian Tibetan Autonomous Prefecture, Qinghai Province, with a total area of 5,856 square kilometers. It is the largest soluble potassium and magnesium deposit in China. In 1958, the first batch of Salt Lakers went deep into the Gobi desert, overcoming the harsh natural conditions, and relied on people to pull the shoulder to produce 950 tons of potash, officially opening the prelude to China’s potash industry production.

In the past 60 years, China’s potash industry has grown from scratch, from small to large, from weak to strong, forming a complete set of industrial systems such as scientific research, design, equipment manufacturing, construction and installation, production, sales, and agrochemical services. The strength has been continuously enhanced, and its potash production technology and single-set production capacity have reached the international leading level.

On August 17, according to media reports, an internal internal memo obtained earlier on Friday showed that the main union of the Caserones mine in Chile had accepted a revised contract proposal from the employer, thus avoiding the threat of strike.
