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 in the middle and late December to the next January is as early as possible in the fertilization period.
The application of wheat wax fertilizer should be carried out according to the seedling system. For weak seedlings with late sowing, poor soil fertility and insufficient base fertilizer, it is necessary to apply sufficient fertilizer to the quick-acting fertilizer, and apply 2000 kg per mu or 20-25 kg of ammonium bicarbonate, or after each rain and snow. Apply 10 kg of urea to the acre to promote tillering. Phosphorus-deficient potassium-deficient wheat field with yellowing of the lower part of the leaves of the wheat seedlings, redness of the tip of the leaves, chlorosis or even necrosis of the old leaf tips, and weak stems, 25 kg of superphosphate, 5-6 kg of potassium chloride or grass ash per mu 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 the strong seedling wheat field with early sowing, base fertilizer and good sensation, the amount of fertilized fertilizer can be applied in an appropriate amount, mainly based on organic fertilizer, combined with the suppression of 1,250 kg per mu of animal manure to supplement the nutrients needed for the growth of wheat seedlings.
Roof Rock Wool Insulation Board
Yu Ou Nuo Roof Rock Wool Insulation Board are suitable for fire prevention, heat preservation and heat insulation of external walls and roofs. Rock wool board is a kind of external wall thermal insulation material, with good thermal insulation effect, low thermal conductivity, high A1 fire grade, non flammability, strong high temperature shrinkage resistance, high quality and low price, which is convenient for construction and installation.Rock Wool Boardis an inorganic fiber board made of basalt as the main raw material through high temperature melting processing , is widely used in petrochemical, textile metallurgy, power transportation, construction agriculture and other fields.
The artificial inorganic fiber made of rock wool board by high temperature melting process has the characteristics of light weight, small thermal conductivity, heat absorption and incombustibility. The initial development is a common type of application in construction, which is mostly used in industrial buildings. Rock wool is a kind of external insulation material. When the market share of 90% of the organic thermal insulation materials is stagnant, rock wool, as an inorganic thermal insulation material for exterior wall, has ushered in an unprecedented market opportunity.
