Industry sources told reporters that with the increase in food prices and the enthusiasm of farmers to grow grain, the demand for chemical fertilizers will also increase, fertilizer market has entered a long period of prosperity.
As a major variety of nitrogen fertilizer, the new wave of urea has come. On the 23rd, as the weather became warmer, the number of end-user buyers gradually increased, and the pre-receipt price of urea manufacturers in Liaoning Province was 2,050 yuan/ton; the wholesale prices in Liaohe and Luxi markets were around 2100-2120 yuan/ton, and the supply from other provinces in Liaoning was quoted as 2050-2070 yuan / ton.
In addition, the mainstream price range of Shandong is 1980-2020 yuan / ton; Henan price range is 2000-2020 yuan / ton; Guangxi region quoted at 2150-2200 yuan / ton. Before the Spring Festival, the urea companies in various regions quoted at 1,850 yuan/ton.
Insiders pointed out that rising cost prices are the inherent reason for urea price increases. As coal prices continue to rise, the cost of many coal-head urea production companies has reached 1900 yuan / ton. "As crude oil futures broke through $100/barrel in early February, there is room for further rise in coal prices, and urea production companies urgently need to transfer part of their costs through price increases."
Yang Ruomu, a researcher at Dongxing Securities, said that before the spring plowing this year, the urea storage capacity was significantly lower than last year, and the spring plowing supply would become increasingly tense. With the full implementation of the spring plowing market in March, there is room for further increases in nitrogen fertilizer prices.
On the 23rd, both P and K fertilizers were stable at high levels. The industry believes that with the gradual rise in grain prices, the demand for nitrogen, phosphorus and potassium, the three major varieties of chemical fertilizers, will also increase steadily, providing strong support for the continued rise in fertilizer prices.
In recent years, due to the effects of greenhouse gases, extreme weather events such as severe cold, high temperatures, snowstorms and droughts have occurred many times in the world. The production cuts caused by inclement weather severely affected the food supply and pushed up food prices.
Yang Ruomu believes that rising food prices will directly increase farmers' enthusiasm for growing grain. However, at the stage of rapid urbanization, it is more difficult to increase the area of ​​cultivated land. The main means for raising and stabilizing grain production depends on chemical fertilizers.

Mechanical properties of injection connector fittings as far as connection functions are concerned, insertion and extraction forces are important mechanical properties. Plug force is divided into insert force and pull out force (pull out force is also called separation force), the requirement of both is different. In the relevant standards, there are provisions for maximum insertion force and minimum separation force, which indicate that, from the point of view of use, the insertion force should be small (hence the structure of LIF with low insertion force and ZIF without insertion force), and if the separation force is too small, it will affect the reliability of contact.
Another important mechanical property is the mechanical life of the connector. Mechanical life is actually a kind of durability index, which is called mechanical operation in GB5095. It is based on a cycle of one insert and one pull, and whether the connector can normally complete its connection function (such as contact resistance) after the specified plug cycle. The plug force and mechanical life of the connector are related to the plating quality (sliding friction coefficient) of the contact part of the contactor structure (positive pressure size) and the dimensional accuracy (alignment) of the contactor.
