The role of calcium nitrate in apple production
Diesel test equipment is used to test and diagnose different diesel injector and pump of diesel injection system.
There are mainly mechanical diesel injection system and electronic diesel injection system.
Three types diesel electronic injection systems are popular in the market, which is high pressure common rail injection system, HEUI injection system and EUI EUP injection system.
Common Rail Test Bench is for common rail injector of Bosch, Denso, Delphi, Cummins, Siemens, Caterpillar etc.
HEUI tester is for HEUI injector like CAT C7, C9, C-9, C3126A, C3126B, 3412E, FORD G2.8, FORD G2.9, NAVISTAR, ISUZU etc.
EUI tester is for unit injector and unit pump, such as Detroit 60 series N2/N3, Caterpillar C12/C13/C15/C18, Cummins N14/M11, Delphi E1/E3,Scania, Iveco, Benz Actors, Benz Atego, Land Rover, Volkswagen PD etc.
Besides, there is also diesel tester for Cummins PT injector and PT pump, X15 Q60 injector etc.
Diesel test bench is easy to operate and maintain, featured of highly accurate, reliable and durable.
   Calcium nitrate is a new type of chemical fertilizer. It has been widely used in developed countries. It not only guarantees the highest content of nitrate nitrogen, but also solves the problem of poor calcium fluidity and poor water solubility. It is a nitrogen-containing and fast-acting calcium. The new high-efficiency compound fertilizer can improve the soil to increase the structure of the pellets so that the soil does not agglomerate, and the apples can rapidly supplement nitrogen and calcium, improve the status of soil nitrogen deficiency and calcium deficiency, promote the normal growth and development of apples, reduce the production cost, and increase the income of the farmers. . The application of calcium nitrate in apple production has several advantages:
First, good safety performance, easy to store and handle
　　 Calcium nitrate is a safer nitrate fertilizer than ammonium nitrate. Due to the presence of calcium, its hygroscopicity is lower than that of ordinary ammonium nitrate, which improves the agglomeration and thermal stability. It is not easy to store and handle. The risk of fire and explosion. Welcome to the company's official website http://
Second, with nitrate nitrogen and available calcium, apples are easy to absorb and utilize
(1) Calcium nitrate is a new type of high-efficiency chemical fertilizer containing nitrogen and available calcium. It contains a large amount of nitrate nitrogen and can be directly absorbed and utilized by plants.
(2) Calcium is one of the essential nutrients for apple growth and development, and plays an important role in the growth and development of apples, which can effectively prevent the occurrence of apple bitter disease. According to an analysis by Apple experts, the demand for calcium in apples is second only to nitrogen and potassium, and higher than phosphorus.
Third, the volatilization loss is small, the utilization rate is high
According to relevant domestic and foreign data, the nitrogen loss of urea and ammonium bicarbonate during storage and use is 40-50 %. The annual environmental pollution caused by the loss of nitrogen in China is also quite serious. Therefore, improving the utilization rate of fertilizers and protecting the environment has become a crucial issue in China's agricultural development. Calcium nitrate contains nitrate nitrogen, which can be directly absorbed by apple without soil conversion. The loss of nitrogen volatilization is small. As a base fertilizer and top dressing, it has quick fertilizer effect and can quickly supplement nitrogen to apple. It is a highly efficient and environmentally friendly fertilizer. Has a good promotion prospects and application value.
