1. Characteristics of nitrosulfur compound fertilizer

1. Quick and efficient: rich in nitrate nitrogen, nitrogen nutrients can be directly absorbed by crops after application, the fertilizer effect is fast and obvious, and the fertilizer utilization efficiency is high.

2. Completely water soluble: The fertilizer dissolves quickly, leaving no residue, and the nutrients are released more evenly, effectively improving the fertilizer utilization rate.

3. Pure potassium sulfate: applied to sulfur-loving crops such as beans, onions, garlic, grapes, tomatoes, etc., can significantly increase the content of protein, vitamin C, etc., and improve the quality and flavor of agricultural products; especially suitable for tobacco-free economic crops such as tobacco, It is a fertilizer for sulfur-loving crops, chlorine-free crops, and saline soils.

4. Promote roots and strengthen fruits: it can coordinate the supply of soil nutrients, improve the growth environment of crops, increase root vitality, promote root development, and enhance the ability of plants to resist drought and disease.

2, the advantages of nitrosulfur compound fertilizer

Nitrogen and sulfur-based compound fertilizers are suitable for upland crops, especially suitable for sulfur- and chlorine-free crops or sulfur-deficient, saline-alkali soils, without residual pollution.

As a base fertilizer or top dressing, it can meet the nutrient requirements of crops at different growth stages and improve their disease resistance and lodging resistance. Practice has proved that nitrosulfur-based compound fertilizer is used for grain crops with full grains, multiple grains, large and even fruits, sweet and delicious, which can significantly improve the yield and quality of crops and increase economic benefits.

Nitrosulfur is mostly used for chemical fertilizers. Compared with other traditional compound fertilizers, it has high nitrogen and potassium, reasonable formula, good solubility, fast fertilizer efficiency, good absorption of phosphorus, potassium and other nutrients, high fertilizer utilization, avoid or reduce nitrous acid in plants Salt accumulation is a new type of compound fertilizer of high quality, high efficiency, environmental protection and pollution-free.

3. Matters needing attention in the use of nitro compound fertilizer

1. Because nitrate nitrogen is very soluble in water and easy to run off, it is not suitable for use in paddy fields and rainy areas in the south; it is not suitable to apply before or after heavy rain in dry land or to pour heavy water after application.

2. Nitrate nitrogen fertilizer should not be mixed with organic fertilizer. Organic fertilizer contains more organic matter. In the case of nitrate nitrogen fertilizer, nitrification will occur under the action of denitrifying bacteria, and nitrogen will be lost.

3. Nitrate nitrogen fertilizer should not be applied in paddy fields. Nitrate is lost with water, reducing fertilizer efficiency. Under anaerobic conditions, nitrate nitrogen fertilizer is easily decomposed by denitrifying bacteria and causes nitrogen loss.

4. Due to the good solubility of nitro compound fertilizer, it is easy to cause the salt concentration in the soil solution to be too high, causing the phenomenon of burning seeds and burning seedlings. Pay attention to the isolation of seed fertilizer when using

5. Apply nitrosulfur compound fertilizer to fruit trees and vegetables. When applying on the fruit trees (ditch application), pay attention to one layer of soil and one layer of fertilizer, and mix the soil and fertilizer; apply on the vegetable crops in the greenhouse, and apply it every 15 days, the dosage should not exceed 30-40 kg / mu.

6. Nitro compound fertilizers should generally be discontinued 20 days before crop harvest to avoid excessive nitrite in crops.
