Tomato Science Potassium

Studies have shown that potassium is one of the indispensable nutrients for tomato growth. Under the premise of sufficient nitrogen and phosphorus, rational application of potassium fertilizer can not only improve tomato yield and comprehensive resistance, but also improve tomato quality and avoid ribs. Rot occurs.

There are currently three major types of potash on the market: potassium chloride, potassium sulfate, and potassium dihydrogen phosphate. When the potassium chloride is applied, the tomato fruit expands slowly and has an adverse effect on the quality. Therefore, potassium chloride is generally not used on tomatoes.

Potassium sulphate is a physiological acid fertilizer, which can be used as base fertilizer and top dressing. When used as a base fertilizer, deep soil application should be adopted. Because of the small change of dry soil moisture in the deep soil, it can reduce the fixation of potassium and improve the utilization of potassium. For top dressing, it can be applied once on sticky soil. It should be applied in stages on soil with poor water retention and fertilizer retention capacity to avoid loss of potassium. Long-term use of potassium sulfate is likely to cause soil compaction, and for this reason, decomposed organic fertilizer should be added.

Potassium dihydrogen phosphate is mainly used for foliar topdressing. The concentration is generally 0.2% to 1%. When formulating fertilizer solution, the fertilizer must be fully dissolved and mixed before use. It is best used in the morning or evening. After the rain, it should be replenished in time.

1. Product introduction

   Coal-based Column Carrier Activated Carbon selects high-quality coal as raw material. The product has developed porosity, large surface area, especially in the large micro-pore volume, high strength, antifriction, impact resistance and easy regeneration characteristics. The high adsorption speed, high capacity; for organic solute, free chlorine and harmful gases in the air has strong adsorption capacity. It is good for the city drinking water advanced purification, removing residual chlorine, bleaching and deodorization, the preferred material in high pure water preparation. It has an irreplaceable role in the production of artificial mineral water. In the field of boiler water, sewage purification has played a significant role. Using Activated Carbon loading masks; air filter can remove airborne bacteria, toxic and harmful gases. The products are divided into columnar, powdery, crushing, briquetting, spherical and other specifications.

2. Application

a. Coal-based column carrier activated carbon used in water treatment industry: tap water, industrial water, sewage treatment, purified water, beverages, food, medical water etc..

b. Coal-based column carrier activated carbon used in air purification: cleaning, deodorizing, adsorption, removal of formaldehyde, benzene, toluene, xylene, oil and gas and other harmful gases.

c. Coal-based column carrier activated carbon used in industry: decolorization, purification, air purification.

d. Coal-based column carrier activated carbon used in fish: filter

e. Coal-based column carrier activated carbon used in reagent: catalyst and catalyst support, coal column carrier activated carbon, mainly used in synthetic industry catalyst or catalyst carrier Granular Activated Carbon.

3. Process  

   Coal-based column carrier activated carbon use the high-quality coal as raw material, through carbonization, activation, cooling, washing and a series of processes developed. Its appearance is generally black cylindrical activated carbon, amorphous granular activated carbon, also known as broken carbon. Cylindrical activated carbon generally by powder raw material and binder, by kneading, extrusion molding by carbonization and activation processes it also can be extruded with powdered carbon and binder.

4. Transportation and Packing

    Woven bag, lined with plastic film bags, each 25kg can also be packaged according to customer demand. The product should be placed in a cool and dry place during storage; When transportation, it prevents to mixed with hard materials, to prevent carbon particles broken that affecting the quality of packaging, to prevent breakage. To avoid leakage or mixed with debris; to avoid water, oil and fire.
