Causes of slow fruit expansion of the latest tomato and its control methods

Tomato is a common vegetable, planting a wide range, many growers are consulting why their own tomato fruit expansion speed is slow, and even the phenomenon of non-fruit expansion. What's going on? The following editor will analyze and analyze for you. Let's take a look at it.

First, the reason for the slow expansion of tomatoes

1. The variety does not adapt.

Some tomato varieties have poor possibility for the environment, are not suitable for local climatic cultivation conditions, and do not have strong tolerance to low temperature in winter. when they encounter continuous cloudy days or bad low temperature weather, the fruit is not easy to expand.

2. the soil fertility is poor.

Many planting land is sandy land, water and fertility conservation is poor, should apply enough organic fertilizer, improve the soil, but many vegetable farmers in the application of base fertilizer is obviously insufficient, sometimes vegetable farmers only apply ternary compound fertilizer, so the fertilizer utilization rate is low, the nutrient content is insufficient, tomato is naturally difficult to apply due to lack of nutrients, in addition, sandy land leakage fertilizer, fertilization is unreasonable, resulting in slow expansion of tomato fruit.

3. Poor temperature and light.

Creating suitable temperature and light conditions for vegetable growth is the key to ensure its normal growth and development. there are many drawbacks in the transformation of many greenhouses, which will lead to its poor thermal insulation and low light transmittance, which can not meet its growth needs. so the fruit expansion speed is slow.

4. Excessive application of nitrogen fertilizer

Excessive application of nitrogen fertilizer is a misunderstanding of fertilization among many growers. Due to the resistance between fertilizers, excessive application of nitrogen fertilizer will lead to the lack of other nutrient elements, resulting in fruit expansion difficulties. In addition, excessive use of nitrogen fertilizer will also affect the similarity of other elements, especially potassium, boron, calcium and other elements, when the elements are sometimes important substances for fruit expansion, once the lack is affecting the fruit expansion.

II. Prevention and control methods

The main results are as follows: 1. Select the seeds of suitable varieties, and select the high-yield varieties with strong stress resistance and suitable for local planting.

2. Do a good job in fertilizer and water management scientifically, give priority to organic fertilizer, apply sufficient base fertilizer, enhance the level of soil fertility, improve the ability of water and fertilizer conservation, and at the same time control the application of nitrogen fertilizer to avoid excessive growth of plants. It is necessary to increase the application of trace elements such as phosphorus and potassium fertilizer and boron and calcium to avoid lack of fertilizer and stiff fruit in tomatoes. The cover can improve the heat preservation performance and light transmittance of greenhouse film, so that the temperature, humidity and light in the greenhouse are suitable for the normal growth of tomato. Control the amount of watering, reasonably prolong the watering time, reduce topdressing, and enlarge the temperature difference between day and night.

The above are the reasons for the slow expansion of tomato fruit and the introduction of control methods, hope to help you, want to know more related knowledge, please follow us.
