Three strategies for hollow tomatoes and poor taste in the greenhouse
Greenhouse tomatoes and field tomatoes tend to have a slightly worse taste, and then there are often hollow tomatoes. We can understand the poor taste, so why do the tomatoes in the greenhouse appear hollow?
The root cause is lack of water.
The reason for the hollow tomato is very similar to the hollow in watermelon production. The root cause is the shortage of water supply. In other words, when the crops are growing normally, due to the external environment, physiological stress and other factors, the tomatoes have insufficient water and nutrient supply, resulting in a hollow in the middle of the fruit. In response to this situation, we can proceed from the following aspects:
First, water properly. The water content of the general farmland is roughly 65% ​​to 75%, and it is recommended to maintain the field moisture at 80% during the fruit development stage after fruit setting. It should be noted that the control of water temperature is particularly important when watering, which affects the occurrence of hollow tomato fruits to a certain extent. Once the water temperature is not coordinated with the soil temperature, it may cause intermittent interruption of nutrients in the growth of crops, so the water temperature should be controlled as much as 10 degrees Celsius or more.
Second, artificial fill light. Tomatoes in greenhouses often suffer from insufficient light, which limits the growth and development of the fruit, and this is also one of the reasons for the hollow. Therefore, in the production management, the strategy of artificial fill light is usually adopted for the greenhouse tomatoes.
Third, use hormones carefully. Hormones are also one of the factors that induce hollow fruit. For greenhouse tomatoes, due to the limitation of space and temperature, the success rate of pollination is low, and production will basically use hormones to stimulate the development of ovary to grow tomatoes. However, we must pay attention to the concentration of hormones used. Excessively high levels will cause the flowers to fall and the fruit will fall, as well as the quality of the tomatoes.
