The application amount of the compound fertilizer is calculated according to the nitrogen requirement of the vegetable. Because vegetables generally require more nitrogen than phosphorus and potassium, priority should be given to nitrogen.
It should be used as the base fertilizer when applying. For vegetables with long-term growth and long-term absorption of fertilizer, 30% of the total fertilization can be arranged for topdressing, or a single nitrogen fertilizer can be used for topdressing.
To be deeply applied. It is best to apply it to a soil layer 10 to 20 cm deep. This is because the phosphorus and potassium nutrients in the compound fertilizer are less mobile in the soil. Therefore, the fertilizer should be applied to the soil layer with dense roots, which is beneficial to the root system to absorb and utilize nutrients.
Apply in combination with organic fertilizers. Although the compound fertilizer has high fertilizer efficiency and is convenient to apply, it is a chemical fertilizer after all, and if it is applied alone for a long time, it will also cause soil compaction. In order to improve its fertilizer efficiency and fertilize the soil, the compound fertilizer should be applied in combination with organic fertilizer.

When saliva is captured in a sterile container, COVID-19 is stable at room temperature for up to seven days without the need for expensive reagents.
Vegetable compound fertilizers with low total nitrogen, phosphorus and potassium nutrients of less than 20% are low-concentration compound fertilizers, between 20% and 40% are medium-concentration compound fertilizers, and greater than 40% are high-concentration compound fertilizers. The application of soil-planted vegetables is generally medium-concentration compound fertilizer, and the application of compound fertilizer for vegetables should pay attention to the following points:
