Second, the product characteristics 1, long-acting carbon ammonium nitrogen utilization rate of more than 35%, 1.5% higher than urea.
2, the validity period is up to 90-110 days, which is twice the urea fertilizer efficiency period.
3, the application of long-acting ammonium bicarbonate compared with the application of the same amount of nitrogen, the average grain yield increased by more than 10%, vegetables, melons and fruits increased by 10-20%; the same yield of long-acting ammonium bicarbonate than urea fertilizer 20-30%.
4, long-acting ammonium bicarbonate can slowly release CO2, can effectively supply CO2 demand in solar greenhouses and greenhouse crops.
5, can promote the development of crop roots. It has drought resistance, lodging resistance and insecticidal sterilization.
6, ammonium bicarbonate can increase the coloring rate of apples, tomatoes, etc., 5-7 days in the morning.
Third, the method of use
1. Autumn Casting: Before the arable land in autumn, the long-acting ammonium bicarbonate will be evenly spread on the surface at a time according to the application amount per mu. It will be turned into the ground at random, and the irrigation will be carried out in time, and the winter and spring will be pressed to prevent nutrient evaporation and the growth period of the crop. No longer apply nitrogen fertilizer.
2. Deep application method: firstly open the ditch 15-20 cm when planting, apply it once along the ditch according to the amount of fertilization per mu, drag it with a hoop or iron block, mix the loam, then apply the farmer's fertilizer according to the normal fertilization amount, then Sowing the soil.
3, inter-fertilization method: when planting corn, sorghum, after the soil breaks the ditch, the fertilizer and the seed are applied without contact with each other, so as to avoid burning the seedlings, it is also possible to use deep ditch, spread fertilization, cover the ridge and cover the soil, and plant the seed in front. Then step on the grid and then cover the traditional methods such as soil.
4. Lateral fertilization method: When mechanized compounding operation is used, the fertilizer bucket, the planter and the laminating machine are used in one operation, so that the seeds and the fertilizer are staggered to prevent the phenomenon of burning.
5. Inter-row fertilization method: In the two rows of planting crops, deep ditch, apply sufficient and long-acting ammonium bicarbonate, cover the soil, sow in the sowing line, then cover the soil and cover the film.
6. Fruit tree fertilizer method: With the trunk as the center, the long-acting ammonium bicarbonate is applied to the circular or semi-annular 15-20CM ditch outside the canopy, or the fertilized ditch is used as the base point for fertilization.
7, vegetable fertilization method: in the ditch, with a sufficient amount of organic fertilizer, deep application of 20CM, after covering the soil ditch, on both sides of the ditch for the seedlings.
Fourth, the amount of application
1. Wheat, corn, rice and other field crops should be 60-70 kg long-acting ammonium bicarbonate.
2. Fruit trees are applied at 2.5 kg per plant.
3, vegetables and other crops are recommended to apply 100-125 kg per mu.
Five, matters needing attention
1. Apply in a deep ditch on the side of the seedling.
2. When long-acting ammonium bicarbonate is used as the base fertilizer, it should be separated by seed fertilizer to prevent burning.
3. Long-acting ammonium bicarbonate only meets the needs of crops for nitrogen. Phosphorus, potassium and other trace element fertilizers are still applied according to normal fertilization amount.
Long-acting ammonium bicarbonate fertilizer application technology
The long-acting ammonium bicarbonate fertilizer has no irritating ammonia smell and is convenient to apply, and can be used as a base fertilizer or a top dressing. As a one-time application of the base fertilizer, it is not necessary to topdress the fertilizer. It has the characteristics of time saving, labor saving, fertilizer saving and low input cost. The long-acting ammonium bicarbonate is not only applicable to rice, wheat, corn, sorghum, soybean, but also to peanuts, cotton, Vegetables, fruit trees, flowers, tea trees and various crops have significant yield-increasing effects, especially in dry areas such as arid and semi-arid areas.
