Most people apply compound fertilizer through the combination of basic application and flushing. Now some vegetables in greenhouses are gradually entering the fruiting stage, especially melons, solanaceous vegetables, and the demand for nitrogen, phosphorus and potassium is large. Therefore, it is necessary to apply a compound fertilizer with different contents to meet the needs of its continuous growth. In the winter, apply compound fertilizer, I hope that farmers should start from the following points: First, less exercise. 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 the crop still requires sufficient supply of nutrients, so it is washed in winter. When applying compound fertilizer, it is necessary to apply less diligence and try to apply it in the morning when the weather is fine. The second is to use pure biological fertilizer (excluding nitrogen, phosphorus, potassium), such as fertilizer (microbial) microbial fertilizer. Pure biological fertilizer contains a variety of beneficial bacteria, which can activate the soil to improve nitrogen, phosphate and potassium release. These organisms can promote the full effect of crops on compound fertilizer. The third is to be targeted. For leafy vegetables, because of their fast growth, high nitrogen requirement and low phosphorus requirement, it is necessary to use compound fertilizer with high nitrogen content and low phosphorus content, while fruits and vegetables have higher demand for potassium in the fruiting period. More, the demand for phosphorus is reduced, and the compound fertilizer with high potassium and low phosphorus can be selected. For the seedlings that are preparing for the simmering vegetables, the demand for phosphorus in the seedling stage is large, and the compound fertilizer with higher phosphorus content can be selected. As the base fertilizer, and after the planting and slowing down the seedlings, apply some compound fertilizer with higher phosphorus content.
