The cause and Control of the Hollow of the latest Tomato

Tomato is a kind of vegetable with plenty of water and sweet and sour taste. It plays a very important role in replenishing the body's moisture and strengthening its resistance. The function is also very high, edible can also be used as feed, and so on. Many farmers will find that there is often a hollow situation in the planting process, so what is the reason why tomatoes are hollow? How to solve the tomato hollowness? Now let's take a look at it together.

1. Sudden drop in temperature

Although tomato is a kind of vegetable that does not like high temperature, but if the temperature is too low, it will also lead to hollow tomatoes. For example, when watering tomatoes, it is generally cold water. The cold water temperature is too low, which leads to thermal expansion and cold shrinkage of the root, and the vitality of the fibrous root decreases. If it happens to be in the ripening and expanding stage of the tomato, the lack of water will lead to a hollow situation. At this time, we should increase the water temperature when watering. It is best if the water temperature is higher than 12 degrees. We can also store the water in the shed and let the water rise to room temperature.

2. Leave too much fruit

Too much fruit will also affect the development of tomatoes, and the fruits on each plant will compete with each other for nutrients, because nutrients are transported from the bottom to the top, so the lower fruits will begin to expand and ripen prematurely. However, the nutrients are basically absorbed by the lower fruit, resulting in the hollow condition caused by malnutrition in the upper fruit. The solution is not to leave too much fruit on one plant, and control the fruit on each plant at 3-5 according to the principle of keeping big to go down and leaving to go up.

3. Planting is too dense

In order to be cheap or to increase production, many farmers will plant far more tomatoes in an acre than the land can bear. Planting too densely will lead to tomato leaves covering each other after growing up, the lower fruit can not be exposed to light and the permeability in the garden becomes worse, resulting in uneven fruit growth and poor development. To form a hollow condition. The planting density should be controlled within the spacing of each 20*20cm, mainly according to the variety and area. Increase the tomato light time and the permeability of the garden, so that each tomato has good respiration and photosynthesis.

4. Shortage of water and fertilizer

Tomatoes need a lot of fertilizer and water every interval from sowing to ripening, and the nutrients contained in the soil are also an important factor in the good development of tomatoes. If there is no enough water and fertilizer for tomato growth, it will lead to tomato stunting, insufficient nutrition supply and imbalance in the body. So that the fruit can not be normally expanded, the occurrence of hollow. Be sure to supplement a large amount of phosphorus and potassium fertilizer and other fertilizers for tomatoes to ensure the nutritional needs of tomatoes. And also keep the soil in the garden fully moist, and finally water it according to factors such as the weather and the growth of tomatoes.

Tomato hollow for farmers is very harmful to their own interests, because tomato hollow will seriously affect the quality and output of tomatoes, lose the competitive advantage, can not enter the market. So I have sorted out the above four causes and prevention methods of hollowness for you. I hope it will be helpful to you.
