2. Ammonium bicarbonate: The chemical nature of ammonium bicarbonate is not very stable, and it has the characteristics of easy volatilization. Under the same conditions, the utilization rate of deep application and overburdening is 20-30% higher than that of ground application, which is higher than the shallow utilization rate. 10-15%. Ammonium bicarbonate should be used as basal fertilizer and top dressing. When used as base fertilizer, apply 15-20 centimeters of depth and embed the soil after application to prevent evaporation losses. At the same time to avoid the application of high temperature season and high temperature period, as far as possible in the season when the temperature is lower than 20 °C, the day is as far as possible when the early and late temperatures are lower, to avoid decomposition and volatilization, to prevent burning the crop leaves, improve fertilizer utilization.

3. Diammonium Phosphate: Diammonium Phosphate is a high-concentration, quick-acting fertilizer suitable for a variety of crops and soils. It is particularly suitable for hi-am phosphorus-requiring crops. It should be used as a base fertilizer. If it is topdressing, it should be applied early and deep. 10 centimeters after the application of soil, can not be too close to the crop, so as not to burn the crop. When used as a fertilizer, it cannot be in direct contact with the seeds. Do not use diammonium phosphate with water, otherwise most of the nitrogen will remain on the surface, and do not mix with alkaline fertilizers such as grass ash and lime to prevent the volatilization of nitrogen and reduce the effectiveness of phosphorus.

4. Ammonium Nitrate: Ammonium nitrate is easily soluble in water, easily absorbs moisture and agglomerates, and is prone to thermal decomposition. The product is generally made into pellets. After being applied to soil, it quickly decomposes into ammonium ions and nitrate ions, and ammonium ions can be absorbed by the soil. Nitrate ions are not easily preserved by soil and are easily lost with water. Therefore, it is not suitable for top dressing and paddy field application.

5, superphosphate: superphosphate can dissolve in water, acidic fast-soluble fertilizer, can be applied in the neutral, calcareous soil, can be used as base fertilizer, top dressing, but also can be used as top-dressing. Note that it must not be mixed with alkaline fertilizers to prevent acid and alkaline neutralization and reduce fertilizer efficiency. Mainly used in phosphorus-deficient soil, the application should be based on the degree of soil phosphorus depletion, foliar spray concentration of 1-2%.

Applicable to all kinds of crops and soil, should be applied to the application of acupuncture, acupuncture, roots, concentrated application or mixed with organic fertilizer, can improve utilization. However, it cannot be directly used as a seed fertilizer because the free acid contained in it will cause seed burning and seedling burning.

6. Calcium, Magnesium and Phosphate Fertilizer: Calcium, Magnesium Phosphate Fertilizer is a kind of multi-element fertilizer containing phosphorus, calcium, magnesium, silicon and other ingredients. It is insoluble in water and alkaline fertilizer. It is suitable for acidic soils and its fertilizer efficiency is slow. It is used as base fertilizer. Deeper is better. It cannot be mixed with superphosphate and nitrogen fertilizers, but it can be applied in combination with the application of acidic fertilizers. It is effective in acidic soils that lack silicon, calcium and magnesium. Not suitable for use in neutral and alkaline soils, nor as top dressing. After the application of calcium, magnesium and phosphate fertilizers, the utilization rate of the crops in the current season is very low. Therefore, it is not necessary to apply the phosphate fertilizers in successive plots every year. It is advisable to apply them every other year to increase efficiency.

7. Potassium chloride: Potassium chloride is the main chemical potash fertilizer, which not only promotes the formation of plant proteins and carbohydrates, enhances lodging resistance, improves and enhances the quality of agricultural products, but also balances nitrogen and phosphorus in plants. The role of other nutrient elements. It can be used as base fertilizer and topdressing fertilizer, but it should not be applied on saline-alkali land to prevent increase of salt damage, nor can it be applied to boiled crops such as potato, sugar beet, tobacco leaf, tea tree, citrus, grape, etc. It should be used as little or as little as possible during dry seasons in arid regions.

8. Potassium sulfate: Potassium sulfate is a chemically neutral, physiologically acidic fertilizer. The reactions and precautions applied in different soils are as follows: In acidic soils, excess sulfate radicals will make the soil acidic, and even exacerbate the toxicity of active aluminum and iron in the soil to crops. Under flooding conditions, excessive sulfate will be reduced to hydrogen sulfide, causing the root damage to become black. Therefore, the long-term consumption of potassium sulfate must be combined with farmyard manure, alkaline phosphate fertilizer and lime to reduce acidity. In addition, paddy fields should also be combined with drainage and drying fields to improve ventilation. In calcareous soils, sulfate and calcium ions in the soil form calcium sulfate (gypsum) that is not easily soluble. Excessive calcium sulfate will cause soil compaction, at this time should pay attention to increase farmyard fertilizer. Focus on the use of chlorine crops, such as tobacco, tea, grapes, sugar cane, beets, watermelons, potatoes and other potassium sulfate not only increase production, but also improve the quality. Potassium sulphate is more expensive than potassium chloride, and it has less supply. It should be used on chlorine-sensitive and hi-potassium-sweetened economic crops, and the benefits will be better.

Lycium sweet nature, Ping, owned by the liver and kidney, with nourishing liver and kidney, Liver eyesight effect, often with Rehmannia, chrysanthemum, yam, cornus and other drugs with the use. Modern medical research shows that it contains the carotene, betaine, vitamin A, vitamin B1, vitamin B2, vitamin C and calcium, phosphorus, iron, etc., with increased white blood cell activity and promote hepatocyte regeneration pharmacological effects of modern pharmacological experiments show that: Wolfberry has enhanced immune function, inhibition of tumor, lowering blood sugar, lipid-lowering, anti-fatigue and other functions. "Materia Medica remarks," that medlar can make "gas can be filled, blood can make up, Yang can be health, Yin can be long, rheumatoid can go, there are ten wonderful Yan." In the "Compendium of Materia Medica," the main Chinese wolfberry Efficacy summarized as "Kidney, lungs, eyesight," concise, in line with reality. Kidney Yin deficiency, lack of liver blood, causing Yaoxisuanruan, dizziness, tinnitus, nocturnal emission embolism, should use medlar.
