The latest Summer Tomato Fertilizer and Water Management

Tomatoes must be a vegetable that everyone is very familiar with. They have a very wide planting area in our country. Rich in nutritional value, fertilizer and water management is very important when growing tomatoes. Especially in summer, if the fertilizer is insufficient, it will affect the summer of tomatoes. So how do summer tomatoes manage fat and water? The following small series will bring you summer tomato fertilizer management, let's take a look!

1. Pouring enough planting water

When planting tomatoes in summer, pay attention to pouring sufficient planting water when planting them. Then, when the seedlings are slow, they should be watered twice or so, and then they should start squatting. Before the tomato plants are not fruiting, pay attention to controlling the amount of watering, and do not irrigate with large water. Avoid excessive plant water absorption caused by plant growth, thus affecting the plant fruit set. The time of watering is usually two days and five days after planting. When planting, you can put a proper amount of diammonium phosphate in the planting hole to supplement phosphorus for the plant, promote the growth of the root, and speed up its slow seedling speed.

2. Management after fruiting

Fertilizer and water management of tomatoes after summer fruit setting is very important. Because tomatoes after fruit setting, the demand for nutrients and water will rise sharply, requiring adequate nutrients. Coupled with the higher temperature in summer, water evaporation speed is fast, so we must pay attention to watering work. Generally watering once every 5 days or so, do not water at noon, otherwise not only the effect is not good, but also easy to burn plants. At the same time, it is necessary to strictly control the dosage, not too much, to avoid adverse phenomena such as waterlogging and fertilizer damage, but also affect the growth of tomatoes.

3. Fertilization of tomatoes

When fertilizing tomatoes, the fertilizer is mainly nitrogen and potassium. Pay attention to controlling the nutrient ratio in each stage of fertilizer application, for example, the ratio of nitrogen, phosphorus and potassium in base fertilizer should be kept at about 1:0.5:1.4. The top dressing method is mainly flushing fertilizer, which should be applied about 5 times in the whole growth period, and the fertilizer is mainly water-soluble fertilizer. Pay attention to control the dosage, each time the dosage should be kept at about 10kg/mu, especially not partial nitrogen fertilizer, to avoid excessive growth. Then when the fruit turns red, reduce the amount of fertilizer and water appropriately to avoid cracking. When topdressing, it is best to be able to cooperate with watering, it is best not to irrigate empty water.

4. Medium and trace elements

It is also very important to supplement trace elements in summer tomato plants. After we set fruit in tomatoes, we should pay attention to supplementing trace elements for them. Boron-calcium fertilizer should be supplemented by foliar fertilizer, spraying fertilizer once every 10 days or so, spraying 5 times or so. In addition, we should pay attention to the supplement of other trace elements. Humic acid spray can be added properly when calcium is added to plants, which can enhance the absorption ability of calcium by plants. Delays the speed of leaf senescence, reduces the bad phenomena such as wrinkled skin and cracked fruit, and improves the quality of tomato fruit.
