Plowing the bottom of the fertilization While cultivating the land, use the plowing bottom fertilizer machine to apply the base fertilizer. Technical points: the depth of fertilization is 10 to 25 cm; the width of the fertilizer belt is 3 to 5 cm; the fertilizer is uniform and continuous, and there is no obvious broken strip; the amount of fertilizer meets the agronomic requirements for crop cultivation.
The deep application of fertilizers mainly uses the fine-casting fertilizer spreader 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 deep application, and lateral deep application of chemical fertilizer. Applied to the side of the seed, 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 burning and seedling phenomenon of the seed and fertilizer mixture; the width of the fertilizer belt is slightly larger than the seeding width; The fat strips are even and continuous, no obvious broken strips and leakage; the soil depth is consistent. The soil is broken and the land is flat.
Deep application of topdressing Mainly using fertilizer-seeding machines, medium-fertilizer fertilisers and other machinery to carry out fertilizer application in the growth stages of crops (main link). Technical points: The amount of fertilizer should meet the nutrient requirements of the crops in each 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 crops are avoided as much as possible; the width of the fertilizer belt is 3 to 5 cm, and the fertilizer is uniform and continuous. No broken strips are applied.
