Served vegetable greenhouse fertilizer to see five

First, look at the types of vegetables to fertilize. The variety of nutrients required by different kinds of vegetables is different. The amount of nitrogen required by leafy vegetables is large, while the solanaceous fruits need a lot of phosphorus and potassium in addition to nitrogen. Eggplant, tomato and green pepper are all solanoids, but Tomato needs more potassium than eggplant and green pepper. The roots of the beans have a nitrogen fixation effect, and the nitrogen fertilizer can be appropriately applied.

Second, look at fertilization during the birth period. The different types of nutrients and nutrients in the same growth period of the same crop are not the same, and should be changed when fertilizing. Fruits and vegetables need little fertilizer in the seedling stage, but they are rich in nutrients. Therefore, the quality of the nutrient soil in the seedling stage is the key to cultivating strong seedlings, and the amount of fertilizer absorbed in the initial harvest period accounts for about 70% of the total growth period. Therefore, it is necessary to re-collect the mixed fertilizer at this time.

Third, look at the weather conditions and topdressing. The utilization rate of fertilizer varies with changes in temperature, moisture, and light conditions. When the temperature is suitable for water and the light is sufficient, the utilization rate is high, otherwise the utilization rate is low. Therefore, when topdressing, it should be properly filled with water after topdressing or topdressing in the warm and sunny weather.

Fourth, look at soil fertilization. Sandy soil has poor fertility. If the amount of fertilizer applied is too large, it will cause nutrient loss. It is necessary to adopt a fertilization method that eats less meals. The viscous soil has good fertilizer-preserving ability. It can take one more appropriate fertilization, reduce the number of top dressings, and save labor. save time.

Fifth, look at fertilizer fertilization. Generally, agricultural fertilizer is used as the base fertilizer, while human feces and pig manure contain more nitrogen, which is suitable for leafy vegetable base fertilizer; poultry manure contains more phosphorus and potassium, and should be used as fruit and vegetable base fertilizer. Fertilizers and fertilizers should be applied in combination with nutrient content, such as stone and potassium sulfate. The base fertilizer and top dressing should also be matched in terms of nutrient type and content. For example, in the cultivation of tomato base fertilizer, the combination of nitrogen, phosphorus and potassium is suitable, lack of calcium, calcium fertilizer is added in topdressing, and calcium deficiency tomato is easy to get umbilical rot.
