Information

Calcium cyanamide is also called calcium cyanamide,generally the nitrogen content of calcium cyanamide is about 20%~22%,calcium cyanamide is a good fertilizer with great use value in the production of pollution-free agricultural products at present,and it is also a soil purifying agent with dual use of medicine and fertilizer.Calcium cyanamide has the dual functions of soil disinfection and soil fertility improvement,and is commonly used in vegetable planting areas.
The role of lime nitrogen:First,the application of lime nitrogen can improve soil structure,inhibit the occurrence of pests and diseases,thereby improving the quality and yield of vegetables.Second,calcium cyanamide contains more than 38%calcium,which can meet the needs of plant growth for calcium,especially for calcium-loving plants.Thirdly,the calcium cyanamide releases the nitrogen slowly,and the ammonium nitrogen formed by the decomposition of the calcium cyanamide is not easy to run off in the soil,the fertilizer effect period can reach 3 to 4 months,so that the demand of vegetable crops for nitrogen fertilizer in the early stage of growth can be met,the application amount of chemical nitrogen fertilizer is reduced,and the pollution of nitrate content in agricultural products to underground water is reduced.
Function 4.Lime nitrogen can decompose calcium hydroxide in the soil,neutralize acidic soil,prevent crop calcium deficiency,and reduce the occurrence of physiological fruit diseases,such as tomato navel rot,dry heartburn of cabbage,etc.,Lime nitrogen can also increase the storability of fruits and vegetables.
Function 5.Lime nitrogen can promote the separation of dry straw and other organic matter in compost
Function 6.Lime nitrogen can break the dormancy of grape vines.The main components of common grape sleep breakers are lime nitrogen and cyanamide,which mainly promote the early degradation of the growth inhibitor ABA(abscisic acid)in grape dormancy,and to some extent replace the need for low temperature.Biological effects of cold capacity.
