In China, N fertilizer applied to the field, crops only 30% of its absorption and utilization, while developed countries have reached 40% to 45%. Because of this, how to improve China's nitrogen fertilizer utilization has become a problem that needs to be solved urgently in production. According to my practice, the techniques for increasing fertilizer utilization are as follows:
1, urea mixed with oxalic acid. In the case of applying 200 kg of nitrogen fertilizer, 140 kg of phosphate fertilizer, and 60 kg of potassium fertilizer per hectare (15 mu) of land, the application of 5 kg of oxalic acid can reduce the number of nitrogenated bacteria by 63%, and increase the number of nitrogen-fixing bacteria by 4.6 times, making the use of nitrogen fertilizer. The shelter increased by 17.3%.
2, urea plus borax. Adding a certain amount of borax in urea can effectively reduce the volatilization loss of nitrogen and increase the nitrogen utilization rate. The ratio of nitrogen to boron is preferably 400:1 or 500:1, which generally increases production by about 10%.
3, the application of efficient coating urea. This fertilizer is in urea granules
Povidone Iodineis a high effective and broad-spectrum disinfectant. Having killing function for most gram-positive bacterium, gram-negative bacterium and mycete. It can disinfect the animal's body, utensil, surgical site and skin mucosa. Clinically applied to sensitive bacteria microbe disinfection, it has powerful killing function for Newcastle disease, avian influenza, infectious broncheitis, infectious laryngotracheitis, colibacillus, salmonella, swine fever, erysipelas, blue ear disease, eircovims.
