Before the tomato plants set fruit, we should pay attention to control the amount of water, do not pour water. Avoid the plant to absorb too much water to cause the plant to grow, thus affecting the plant fruit setting. The time of watering seedlings is usually two days and five days after planting. When planting, an appropriate amount of diammonium phosphate can be put into the planting hole to supplement phosphorus for the plant, promote the root growth and speed up the slow seedling speed.

2. Management after fruit setting

The fertilizer and water management of tomatoes after fruit setting in summer is very important. Because the tomato after the fruit, the demand for nutrients will rise sharply, the need for adequate nutrients. In addition, the temperature in summer is higher and the rate of water evaporation is fast, so we must pay attention to watering. Generally every 5 days or so watering, can not be watered at noon, otherwise not only poor effect, but also easy to burn plants. At the same time, we should strictly control the dosage, not too much, to avoid waterlogging, fertilizer damage and other bad phenomena, but will also affect the growth of tomatoes.

3. Fertilization of tomatoes

When fertilizing tomatoes, the main fertilizers are nitrogen and potassium. Attention should be paid to controlling the proportion of nutrients in fertilizers at each stage, for example, the ratio of nitrogen, phosphorus and potassium in base fertilizer should be kept at about 1 ~ 0.5 / 1.4. The main method of topdressing is flushing fertilizer, which should be applied about 5 times in the whole growth period, and the fertilizer is mainly water-soluble fertilizer. Attention should be paid to controlling the dosage, and each dosage should be kept at about 10kg/ mu, especially the application of nitrogen fertilizer should not be partial to avoid overgrowth. Then, when the fruit turns red, properly reduce the amount of fertilizer and water to avoid fruit cracking. When topdressing, it is best to cooperate with watering, and it is best not to pour empty water.

4. Medium and trace elements

The supplement of trace elements in summer tomato plants is also very important. After we sit on the tomato fruit, we should pay attention to the supplement of trace elements for it. It should be supplemented with boron and calcium fertilizer in the way of foliar fertilizer, which can be sprayed once in about 10 days and about 5 times. In addition, we should also pay attention to the supplement of other trace elements. When replenishing calcium for the plant, some humic acid spray can be added appropriately to enhance the absorption ability of the plant to calcium. Delay the senescence of plant leaves, reduce the bad phenomena such as wrinkling and cracking, and improve the quality of tomato fruit.
