Causes and Solutions of malformed Tomato fruits

Tomato is a common vegetable. With the continuous expansion of its planting area, its abnormal fruit phenomenon is becoming more and more common, which has become an important factor affecting the quality and yield of tomato. How to prevent and control tomato malformed fruit is also a problem that farmers need to solve at present. So what's with the malformed tomato fruit? How to solve it? Come and have a look with the editor.

1. The cause of malformed tomato fruit

1. The temperature is not suitable

If the temperature is too high or too low during the period of tomato flower bud differentiation, it will affect the normal flower bud differentiation of tomato. Once the flower bud differentiation is not good in the early stage, it will lead to abnormal fruit in the later stage. For example, the temperature of tomato flower bud differentiation in winter should not be lower than 12 degrees at night, and it should not exceed 30 degrees in summer and daytime, but the temperature in many areas is relatively high in summer and autumn, and it is normal to have a temperature of more than 35 degrees during the day, so it causes later deformities.

2. Improper operation of dipping flowers

Dipping hormone concentration is too high, especially in the high temperature period, it is necessary to appropriately reduce the dipping concentration, otherwise it will also form abnormal fruit, or dipping time is not appropriate, for example, dipping flowers too early is easy to form stiff fruit, too late will cause fruit cracking.

3. Nutrient imbalance

The growth and development of tomato needs a variety of nutrients, if the lack of some nutrients, it will also cause fruit deformities, especially the lack of trace elements, such as calcium deficiency, boron deficiency can easily cause deformed flowers and deformed fruits. If the vegetative growth is too late, or if there is continuous overcast and rainy weather in the fruit period, it is very easy to cause the overgrowth of the plant, affect the reproductive growth of the plant, and make the nutrients needed for the growth of flowers and fruits insufficient, thus forming deformed fruits.

II. Solutions

1. Control temperature

In particular, we should pay attention to the control of the temperature in the shed should not be too high, should not exceed 35 degrees for a long time, can be through flood irrigation, pull shading net, spray cooling agent and other measures to reduce the temperature.

2. Scientific fertilization

In tomato production, it is necessary to apply reasonable fertilizer and pay attention to the application of organic fertilizer to ensure a balanced cause. when the plant is lack of trace elements, it can be supplemented by foliar spraying, such as spraying low concentration borax solution in fruit stage. can promote fruit expansion, through variety and yield.

3. Rational use of dipped anther

When dipping flowers, we should pay attention to the concentration of dipping anthers, which decreases with the increase of temperature, on the contrary, if the temperature is lower, the concentration can be increased appropriately. Generally speaking, the concentration of dipping flowers is 10~20ppm, and the higher the spikes are dipped, the lower the concentration is.

4. Timely fruit thinning

If abnormal fruit is found on the plant, it must be removed in time, especially the first ear fruit delayed in autumn, because the early high temperature is easy to form deformed fruit, the earlier it is thinned, the more nutrient waste can be prevented. And the first ear fruit is not easy to leave too much fruit, generally 2-3 normal fruit.
