　 Increasing the application of wax fertilizer during the wintering period of wheat can not only supplement the deficiency of base fertilizer and seedling fertilizer, consolidate and increase the tillering before winter, promote root development, achieve the purpose of root health and strong winter, and maintain and stabilize the soil temperature of wheat roots. Degree, through the slow decomposition of fertilizer in winter, is absorbed by the roots, accumulate and store a large amount of nutrients, laying the foundation for the spring growth of wheat.
The fertilizer is mainly rich in organic matter and warm with fertilizers, such as soil fertilizer, compost, manure, river mud, Chen wall soil, human and animal manure, and other effective and long-lasting organic fertilizers. Generally, the application of the wax fertilizer is from mid - late December to mid- January , and the earlier the application in the fertilization period, the better.
The application of wheat wax fertilizer should be carried out according to the seedling system. Late planting Dissimilar field and under weak seedling base fertilizer, fertilizer to be applied enough wax to available fertilizer, Kraal pig manure composting per acre 2000 kg ammonium hydrogen carbonate or 20 to 25 kg, while after the snow or each Apply 10 kg of urea to the acre to promote tillering. Barley lower leaves of yellow, red tip, tip chlorosis or necrosis old leaves, stem thin Deficiency of potassium wheat field, increasing superphosphate 25 kg per acre, potassium chloride or 5 to 6 kg Grass ash 100 ~ 150 kg. The ash can absorb heat and prevent wheat from being frozen. The wheat field with good base, good soil fertility, early sowing and long growing conditions should control the amount of wax fertilizer, mainly organic fertilizer such as river mud, less or no chemical fertilizer, and take measures such as suppression to control the growth and control. To improve the wintering environment of wheat. For sowing early, basal foot, good moisture seedling wheat field, an appropriate amount of wax applied fertilizer, organic fertilizer, livestock manure applied per acre of repression combined with 1250 kg, to supplement the nutrients required for the growth of wheat seedling.
Kemei designs, tests, and builds all types of grinding wheels. The aim of abrasive grinding wheels is to modify the surface structure and/or preparation of a workpiece. In general, fixed abrasive wheels are characterized by grit size (abrasive grain), bonding type, substances used, and the grade and structure of the fine grinding wheel. Users of our wheels can choose between a specially formulated wheel tailored to their exact needs, or choose one of our reliable standard specifications. Additionally, the physical and chemical properties of the diamond and/or CBN crystals can influence the performance of the grinding wheel. Having over 20 years of experience in our field has earned us the prestige of manufacturing the highest quality fixed super abrasive wheels and abrasive grinding wheels. Above all, being an abrasive wheel manufacturer, allows us to offer you success in your future projects.
Kemei produce and aim on the following types grinding tools, such as aluminum oxide grinding wheel, silicon carbide grinding wheels, mounted points, Diamond Grinding Wheels, CBN Grinding Wheels and all types of saw blades and cut off wheels.
If you need any type of grinding tool or professional advice about grinding on your workpieces. Don`t hesitate to contact us!
