A farmer friend asked: What is the disease of tomato fruit rotten? What is the cause of the disease? How to prevent?
A: Tomato rotten fruit is a physiological disease. The cause of the disease is the lack of calcium in the fruit (especially in the top part of the fruit), as well as the imbalance in water supply and excessive nitrogen fertilizer application. The prevention and control measures are: timely watering and balanced water supply; controlling the amount of nitrogen fertilizer and using phosphorus and potassium fertilizers; selecting sandy loam for planting; acidic soil can be properly put in some lime; using 1% superphosphate calcium water extract for extra-root fertilizer; use pericarp Thicker, smaller flower marks.
Filtration rod filters Equipments
Describe:
Filter rod filter equipment can be divided into: ceramic membrane filter rod, stainless steel strong magnetic rod filter, stainless steel titanium rod filter. In the process of industrial production, ceramic membrane filter rod is used to treat waste water, raw water and waste liquid. The waste water can reach the national discharge standard or recycle after passing through ceramic membrane filter.
Classification and applications:
The core component of ceramic membrane filter is ceramic filter rod. It uses acid-resistant ceramic particles or quartz, corundum sand and other raw materials as the main raw materials, and adds a small amount of inorganic binder and reinforcements to carry on scientific formulation. Grading, molding, film making and other processes from processing.
Titanium rod filter uses titanium powder sintered filter element, which is made of hollow filter rod by high temperature sintering of titanium metal powder by powder metallurgy method. It is widely used in the separation of liquid and solid in food, beverage, medicine and chemical industry. It is often used in coarse filtration or intermediate filtration. The filter element has the advantages of high temperature resistance, corrosion resistance, high mechanical strength, and the filter element can be reused repeatedly. Filter equipment housing material is 316l or 304 stainless steel.
Stainless steel strong magnetic rod filter has a magnetic rod with high quality stainless steel tube and high B value rare earth alloy neodymium boron. It is made by special manufacturing method and is used to gather the powder transported by liquid, slurry flow and air supply pipeline. The strong magnetic iron impurity in gas and other enterprise phase is widely used to remove iron from high temperature condensate and back water in power industry. Also used for fluid food filling line fine metal impurities removal to ensure food safety.
