Reasons for Slow Fruit Enlargement in Tomatoes and Control Methods
Tomatoes are a common vegetable with a wide planting range, and many growers ask why their own tomatoes enlarge slowly, or even fail to enlarge at all. What is going on here? Below, the editor will analyze this for everyone, so let's take a look.
1. Reasons for slow fruit enlargement in tomatoes
1. Varieties not suited to the conditions
Some tomato varieties have poor adaptability to the environment and are not suitable for the local climate and cultivation conditions, with weak tolerance to low temperatures in winter. When continuous cloudy days or low-temperature bad weather occur, the fruit is not easy to enlarge.
2. Poor soil fertility
Many planting plots are sandy soil with poor water and fertilizer retention. Organic fertilizer should be applied in sufficient amounts to improve the soil, but many vegetable growers clearly apply insufficient base fertilizer, and sometimes only apply ternary compound fertilizer, so the fertilizer utilization rate is low and the nutrient content is insufficient. Tomatoes naturally find it hard to get enough nutrients because of the lack of nutrients. In addition, sandy soil leaks water and fertilizer, and fertilization is unreasonable, which leads to slow fruit enlargement in tomatoes.
3. Poor temperature and light
Creating suitable temperature and light conditions for vegetable growth is the key to ensuring normal growth and development. Many greenhouses have many drawbacks during renovation, which leads to poor heat preservation and low light transmittance, unable to meet its growth needs, so the fruit enlargement speed is slow.
4. Excessive application of nitrogen fertilizer
Excessive application of nitrogen fertilizer is a fertilization misunderstanding that many growers have. Due to the antagonistic effect between fertilizers, excessive application of nitrogen fertilizer will lead to a deficiency of other nutrient elements, thus making fruit enlargement difficult. In addition, excessive use of nitrogen fertilizer will also affect the uptake of other elements, especially potassium, boron, calcium and other elements. These elements are sometimes important substances for fruit enlargement, and once deficient, they will affect fruit enlargement.
2. Control methods
1. Choose suitable variety seeds, and select high-yield varieties with strong stress resistance and suitability for local planting.
2. Do a good job in fertilizer and water management scientifically, mainly using organic fertilizer, apply sufficient base fertilizer, enhance the soil fertility level, and improve water and fertilizer retention capacity. At the same time, control the application of nitrogen fertilizer to avoid excessive vegetative growth of the plants. Increase the application of phosphorus and potassium fertilizers and trace elements such as boron and calcium, so as to avoid stiff fruit caused by nutrient deficiency in tomatoes. Also improve the heat preservation performance of the greenhouse and the light transmittance of the greenhouse film, so that the temperature, humidity, light and other conditions in the greenhouse are suitable for the normal growth of tomatoes. Control the amount of watering, reasonably extend the watering time, reduce topdressing, and increase the temperature difference between day and night.
