Acidic fertilizers should not be mixed with alkaline fertilizers. Ammonium bicarbonate, ammonium sulfate, ammonium nitrate and ammonium phosphate cannot be mixed with alkaline fertilizers such as grass ash, lime, kiln ash and potassium fertilizer, and neutralization reaction will occur, resulting in loss of nitrogen and reducing fertilizer efficiency. Chlorine-containing fertilizers should not be used on saline and alkaline crops. Chlorine crops include tobacco, beets, potatoes, tea trees, peach trees, grapes, citrus, sugar cane, and watermelon.
Nitrogen fertilizer should not be applied before shallow application or watering. Nitrogen fertilizers are generally converted to ammonium nitrogen after being applied to the soil, which is easily lost with water or volatilized by light and heat, and loses fertilizer efficiency.
Ammonium bicarbonate and urea cannot be mixed. The amide nitrogen in urea can not be absorbed by crops. It can only be used by crops after being converted into ammonium nitrogen by the action of gland enzymes in the soil. After carbon iron is applied to the soil, the soil solution will be acidic in a short time and will accelerate. The volatilization loss of nitrogen in urea cannot be mixed. Ammonium bicarbonate can not be mixed with bacterial fertilizer, because the former will emit a certain concentration of ammonia gas, which has a toxic effect on the latter's active bacteria, which will make the bacterial fertilizer lose its fertilizer effect.
Nitrogen fertilizer should not be applied to legumes. There are nitrogen-fixing rhizobium in the roots of legumes. Excessive application of nitrogen fertilizer will not only cause waste, but also make the crops more mature and affect the yield.
Phosphate fertilizer should not be dispersed. The phosphorus element in the phosphate fertilizer is easily absorbed and fixed by the soil, and the fertilizer effect is lost. The phosphate fertilizer and the fertilizer should be mixed and piled up for a period of time, and then the ditch or the hole is applied near the root of the crop.
Fertilizers with higher phosphorus content should not be used more for vegetables. Vegetables require relatively little phosphorus. Potassium fertilizer should not be applied in the late stage of crop growth. When there is a symptom of potassium deficiency, the crop growth is nearing the late stage. At this time, the top dressing has not played much role. Therefore, the potash should be applied to the crop seedling stage in advance or used as a base fertilizer.
Rare earth fertilizers should not be applied directly to the soil. The amount of rare earth fertilizer is small, and the correct method of use is to mix rare earth fertilizers for foliar application.
It is not advisable to apply fertilizers regardless of crop varieties and growth stages. Different crops and crops of different growth stages have different needs for the variety and quantity of fertilizers. Fertilization regardless of crops and period can only be counterproductive.
Ammonium sulfate should not be applied for a long time. Ammonium sulphate is a physiological acid fertilizer. When applied to the same soil for a long time, it will increase its acidity and destroy the granule structure. In alkaline soil, the ammonium ion of ammonium sulphate is absorbed, while the acid ion remains in the soil and reacts with calcium to make the soil The knot becomes hard.
Unfertilized farmyard manure and cake fertilizer should not be applied directly. Unfertilized farmyard manure and cake fertilizer contain a variety of eggs and germs, and also produce a lot of carbon dioxide gas and heat. Direct use will pollute the soil, accelerate the evaporation of soil moisture, burn out the roots of crops, and affect the germination of seeds. The correct method of use is to first fully pile up the farmyard manure and cake fertilizer, and then use it after high temperature disinfection or chemical treatment.

1% salidroside in rhodiola rose extract is a kind of rhodiola rose extract, is the Key Product of our company, with the stem and leaves of rhodiola rhodiola as raw materials, after extraction, concentration, drying into brown powder.
Rhodiola rhodiola extract is a natural extract extracted from Rhodiola grandiflora, which is refined, concentrated and dried.It is easily soluble in water, soluble in methanol, soluble in ethanol, insoluble in ether.It's stable against heat.
Rhodiola, the name of traditional Chinese medicine.They are the dry roots and rhizomes of Rhodiola roseum, .Mainly produced in the Chinese mainland Jilin, Hebei, Shanxi, Xinjiang and other places."Traditional Chinese Medicine Dictionary" records: Rhodiola "cold, sweet and astringent taste.Promote blood and stop bleeding, clear lung and stop cough.Treatment of cough, hemoptysis, pneumonia cough.
Rhodiola rhodiola is commonly found wild on sunny slopes, stone crevices, alpine meadows, alpine rock crevices, hillside grasslands, shrub margins, and dry sandy soils in mountains.Its adaptability is strong, like slightly cold and humid climate conditions, cold and drought tolerance, soil requirements are not very strict, should choose high altitude, cold climate, short frost-free period, summer day and night big temperature difference in the mountain cultivation.
Loam or sandy loam with rich humus, deep soil layer, sufficient sunshine and good drainage should be selected for cultivation, and forest cut or raw wasteland can be used for cultivation in mountainous areas.
