Fertilization machinery has the following methods for efficient fertilization: JIANFA SANITARY WARE INDUSTRY CO., LTD , https://www.jfsanitary.com
1.Deep application of topdressing
Mainly using fertilizer-seeding machines, medium-duty fertilizing machines and other machinery to carry out fertilizer application in the growth stages of crops (main links). Technical points: The amount of fertilizer should meet the nutrient requirements of each crop in the growing season; the depth of fertilization is 6-8 cm; the fertilization site is generally below the root side of the crop, and the roots of the crop are avoided as much as possible; the width of the fertilizer belt is 3-5 cm, and the fertilizer is uniform and continuous. No broken strips are applied.
2. Fertilizer deep application
Mainly use the fine-casting fertilizer machine and the ditch-casting fertilizer machine to complete the fertilization, covering and repressing operations at the same time of sowing. According to the relative position of fertilization and seeds, there are lateral deep application and deep application, and deep application of chemical fertilizer to the seeds. Below the side, the deep chemical fertilizer is applied directly below the seed.
Technical points: Complete the seed and fertilizer amount according to the agronomic requirements. The soil isolation layer with a certain thickness (greater than 3 cm) between the fertilizer and the fertilizer not only meets the nutrient demand of the crop seedling growth, but also avoids the mixing of seeds and fertilizers, and the phenomenon of burning and burning; the width of the fertilizer belt is slightly larger than the seeding width. The fat strips are even and continuous, with no obvious broken strips and leakage; the soil depth is consistent. The soil is broken and the land is flat.
3. Plowing bottom fertilization
At the same time as arable land, the plowing bottom fertilizer machine is used to apply the base fertilizer deeply. Technical points: the depth of fertilization is 10-25 cm; the width of the fertilizer belt is 3-5 cm; the fertilizer is uniform and continuous, and there is no obvious broken strip; the amount of fertilizer meets the agronomic requirements of crop cultivation.
