Jiaozuo University has developed a new compound fertilizer production technology
On March 1st, it was learned from Jiaozuo University that the two major scientific and technological achievements of the school “Study on the super-constant application of potassium dihydrogen phosphate in wheat production†and “the new process of potassium dihydrogen phosphate production†passed the appraisal hosted by the Provincial Science and Technology Department. The level is at the international leading level and is recommended to be included in the national promotion plan.
In agricultural production, if the fertilization is unreasonable, the proportions of nitrogen, phosphorus and potassium inputs are not coordinated, which may lead to problems such as aggravation of crop diseases, insufficient grain, and poor yellowing. If the crops can be supplemented with nutrients in time, the crops can be greatly improved. Yield. After 20 years of research, it is proved that in the case of conventional fertilization, in the six periods of wheat growth, about 2 kg of potassium dihydrogen phosphate is sprayed reasonably, and the yield per mu is increased by more than 40%. In 2004, 2.88 mu of wheat planted by Meng Tianbao, a villager in Nantun Village, Xiaodong Township, Wuyi County, was super-constantly applied with potassium dihydrogen phosphate to produce 705.64 kg per mu, which was the highest record of wheat production per capita in Jiaozuo City.
The "new process for the production of potassium dihydrogen phosphate" is different from the traditional production method in that potassium hydrogen phosphate, potassium phosphate and potassium chloride are used as raw materials to produce potassium dihydrogen phosphate and three-element compound fertilizer. The cost of the technology is low. Compared with the traditional production method, the cost per ton is reduced by about 1,600 yuan, and no waste water, waste residue and harmful gas are eliminated in the production process, which meets the national standards.
A power tool is a tool that is actuated by a electric power source and mechanism.Power tools are used in industry, in construction, in the garden, for housework tasks and around the house for purposes of driving (fasteners), drilling, cutting, shaping, sanding, grinding, polishing, painting and more.The most common types of power tools included Electric Hand Drill,electric Impact Drill,hand cutting machine,electric wrench,angle grinder etc.
Power tools are classified as either stationary or portable, where portable means hand-held. Portable power tools have obvious advantages in mobility. Stationary power tools, however, often have advantages in speed and precision.
