When the temperature of the ammonium carbonate is low, the ammonium carbonate is not easily decomposed and decomposed, which is beneficial to improving the fertilizer utilization rate. Ammonium bicarbonate belongs to ammonium nitrogen fertilizer. It can be directly absorbed and utilized by crops after being applied to soil. It has fast fertilizer efficiency and is a typical “quick-acting fertilizerâ€. Nitrogen nutrition can be provided to crops in a timely manner. Some people have done experiments to apply ammonium bicarbonate to wheat fields during cold and snowy weather, which is 1 to 1.5 times more effective than in high temperature seasons.
Avoid applying urea urea is an ammonium amide fertilizer. It can not be directly absorbed and utilized by crops after being applied to the soil. It needs to be converted into ammonium nitrogen by the urease secreted by urea bacteria in the soil to be absorbed by the roots. The rate of urea conversion depends mainly on the soil temperature at that time. Under normal conditions, all urea applied to the soil is converted to ammonium nitrogen, which takes 7 to 10 days at a ground temperature of 10 ° C and 4 to 5 days at 20 ° C. It takes only 2 to 3 days at 30 °C. If urea is applied, it tends to affect crop growth because of the slow effect of fertilizer.
The absorption of phosphorus and zinc by phosphorus and zinc fertilizers is significantly affected by temperature and light. In autumn and winter, the temperature is low and the light is insufficient. It is easy to induce phosphorus and zinc deficiency in wintering crops. Phosphate fertilizer and zinc fertilizer should be added appropriately. In addition, phosphorus can enhance the cold resistance of plants, and the application of phosphorus fertilizer is also beneficial to prevent crops from being frozen.

Geogrid
The Geogrid including Polyester Geogrid, Fiberglass Geogrid, Steel Plastic Composite Geogrid and Plastic Geogrid.
The geogrid is a major geosynthetic material. Compared to other geosynthetic materials, it has unique performance and efficacy. Commonly used for reinforcement of soil structure or reinforcement of composite materials.
The uses of geogrid: It is suitable for embankment and embankment reinforcement slope protection tunnel wall reinforcement large airport parking lot wharf cargo yard and other permanent bearing foundation reinforcement.
The feature of geogrid:
The high strength creep can adapt to all kinds of environment soil, and can satisfy the use of high grade highway retaining wall.
It can effectively improve the locking and occlusion of the reinforced bearing surface, greatly enhance the bearing capacity of the foundation, effectively restrain the lateral displacement of the soil, and enhance the stability of the foundation.
More suitable for deep-sea operations, embankment reinforcement, fundamentally solve the other materials do stone cage due to long-term erosion by the sea caused by low strength, poor corrosion resistance, short service life and other technical problems.
It can effectively avoid the construction damage caused by the crushing and destruction of machinery and tools in the construction process.
