First, less application and diligence. The nitrate nitrogen and ammonium nitrogen in the compound fertilizer will absorb some heat during the dissolution process, which may affect the ground temperature and cause adverse effects on the growth of the crop roots. However, the normal growth of crops requires sufficient nutrient supply, so when applying compound fertilizer in winter, it should be applied less and diligently, and try to apply it on sunny days.
The second is to apply pure biological fertilizer (excluding nitrogen, phosphorus, potassium). Pure biological fertilizer contains a variety of beneficial bacteria, which can activate soil improvement and play a role in nitrogen fixation, phosphorus dissolution and potassium release. These biological bacteria can also promote the absorption of fertilizer by crops.
The third is to be targeted. Leafy vegetables grow fast, require more nitrogen, require less phosphorus, and use high-nitrogen and low-phosphorus compound fertilizers; melons and fruits have more demand for potassium in the fruiting period, and less demand for phosphorus. High potassium and low phosphorus compound fertilizer. For the field where the vegetable seedlings are prepared, the demand for phosphorus in the seedling stage is large, and the compound fertilizer with high phosphorus content can be used as the base fertilizer. After the vegetable seedlings are planted and planted, the compound fertilizer with high phosphorus content can be applied in an appropriate amount.
Diamond Wire For Magnetic Material Cutting
When the electroplated Diamond Wire is cut, the workpiece is scratched by the diamond abrasive particles on the circumferential surface. Electroplated diamond wire cutting is widely used in the field of hard and brittle material processing due to its high cutting efficiency and little damage to raw materials. Compared with other hard and brittle materials, magnetic materials such as neodymium, iron and boron have similarities and differences. Magnetic materials such as neodymium, iron and boron are mostly made by powder metallurgy process, and there are large lattices and voids inside the materials. It has a certain influence on the electroplated diamond cutting wire.
