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.

In the late growth stage of soybean, the effect of root-spraying fertilizer production was significant, which was related to the characteristics of soybean fertilizer absorption and soil fertility. Soybean root fertility changes with the growth of the plant to the deep layer of the soil, that is, the soybean first absorbs the nutrients in the upper layer of the soil in the early growth stage, and the nutrients in the soil below the cultivated layer are mainly absorbed in the late growth stage (reproductive growth). According to the test, the percentage of soybean roots absorbed by 10 cm deep nutrients was 93.3% in seedling stage, 62.9% in branching stage, 36.1% in flowering stage, 26.2% in pod-forming period, and almost 10 cm in roots in the drum stage. Nutrients in the deep soil layer, while the amount of nitrogen, phosphorus and potassium required for flowering, granules and maturity accounts for about 80% of the total. This indicates that the peak season of soybean fertilizer is in the stage of reproductive growth, that is, in the late growth stage. These nutrients are extracted from the soil below the plough layer by roots, and the nutrient conversion and release capacity of the soil below the plough layer is much lower than that of the plough layer. This leads to the inconsistency between the nutrient demand and the soil fertility at the peak of soybean fertilizer demand. Sex. Soybean roots (especially lateral roots) are mainly concentrated in the surface soil, and it is prone to undernutrition and premature aging in the middle and late growth stages, which is the main factor limiting the high yield and stable yield of soybean. Therefore, spraying the nutrient solution outside the roots of the soybean pods can alleviate the contradiction between the peak of soybean fertilizer and the ability of soil fertilization, accelerate the accumulation, transformation and transportation of assimilation products, and promote the nitrogen fixation of rhizobium. Root activity increases the ability of roots to take up nutrients.
The preparation method of the nutrient solution is: weigh 0.5 kg of urea, 105 g of superphosphate, 107.5 g of potassium sulfate, 12.5 g of boric acid, dissolved in 25 kg of water, and filtered to be a nutrient solution. Foliar spray should be carried out after 4 o'clock in the afternoon or in the evening, so that the leaves are evenly stained with nutrient solution without flowing, and sprayed 3 times, every interval of 3 to 4 days.

According to foreign data reports, soybean rooting and budding stage root spray fertilizer, grain yield increased by more than 50%. According to the test of Xiongyue Agricultural College, the soybean pods and the granules were sprayed with nutrient solution, and the grain yield increased by 32.06%~54.01%.
