Recently, a headline reader asked the agricultural technology basket: when he bought tomatoes from the vegetable market, he often saw that many tomatoes had more obvious convex edges and angles on the fruit surface, and the inside of the fruit was hollow and sunken after cutting, for such a ridged tomato, many people said that this was caused by a large number of drugs smeared by vegetable farmers in the tomato planting process, which made him dare not buy, did not dare to eat, worried that eating would affect his health.
In fact, ah, tomato fruit surface edge internal cavity problem, most of them are due to the tomato growth process of improper field management, strictly speaking, the tomato with edge cavity is a deformed fruit (hollow fruit), the tomato with edge cavity looks very flesh is not full, the weight is relatively light, after cutting it, you will also find that most of the tomato fruit has less internal colloidal flesh or even the problem of the internal cavity of the fruit, in addition, the tomato with edges tastes relatively poor, not only the acidity is large, and the sugar is relatively low.
It can be said that all tomatoes with edges and cavities are not only low in yield, poor appearance, and low selling price, but also ordinary consumers are reluctant to buy them, because of poor taste and not delicious!
So, what is the cause of the tomato with a angular cavity on the fruit surface? For the majority of vegetable farmers, how can we avoid the ridges or cavities of the tomatoes and fruits they grow? Today, the agricultural technology basket will give you a specific explanation of this problem, because only when you understand the reasons can you know how to avoid this situation.
In fact, the reason why the tomato fruit surface appears angular or internal cavity, the fundamental reason is because the tomato in the process of expansion and development because of the lack of nutrient supply and reserves inside the fruit, resulting in the fruit cavity development is not full, the fruit surface pulp depression caused, the fruit cavity wall is concave, the fruit cavity is concave, so the tomato looks like it grows out of the edge in appearance! The main reasons for the ridged tomato fruit are as follows:
The first reason is related to excessive leaf removal in the middle and late stages of tomato growth, and this is also the most common reason for many greenhouse tomatoes to have raised edges and internal holes. As we all know, in the middle and late stages of tomatoes, the appropriate removal of some old yellow disease leaves in the middle and lower parts is conducive to improving plant ventilation and lighting, reducing the ineffective consumption of plant nutrients, promoting fruit coloring, and improving the overall yield and quality of tomatoes, but if our vegetable farmers pick too many leaves and thin leaves too much in the late stage of tomato growth, then it will greatly reduce the amount of leaves and leaf area on the tomato plant, and then make the tomato photosynthesis to produce nutrients for fruit manufacturing and deliver nutrients greatly weakened, so that the ability of tomatoes to photosynthesize and deliver nutrients for fruit manufacturing has been greatly weakened. It will lead to a decrease in the organic nutrients accumulated in the tomato fruit that is in the rapid expansion stage, and eventually lead to a depression in the tomato fruit due to the lack of filling in the cavity, which will cause the convex edge of the fruit surface with a high cavity wall and a partial depression between the cavity walls.
The second reason is related to the lack of boron during tomato growth. Boron in the process of tomato fruit expansion and development, can play a role in promoting the delivery of nutrients to the inside of the fruit tree, if the tomato fruit in the expansion period of the lack of boron element, then it will cause tomato fruit due to insufficient nutrient supply, fruit absorption and accumulation of nutrients inhibited and the problem of concave and convex surface of the fruit.
The third reason is related to poor light in the fruit stage of tomatoes. Tomatoes need more nutrient supply during the expansion stage of the fruit, if the puffing stage encounters a long period of cloudy rain or in a long period of poor light, then the tomato plant's own nutrient consumption will increase and the organic nutrients produced by leaf photosynthesis will be reduced, which will lead to the rapid expansion of tomatoes because of insufficient supply of nutrients inside the fruit, the filling of the fruit cavity is not full and the problem of appearing convex.
The fourth reason is related to the poor temperature environment during the differentiation period or flowering and fruiting stage of tomato flowering. On the one hand, if you encounter a long period of high temperature (more than 33 degrees) or low temperature (below 13 degrees) during the tomato budding stage, it will cause the problem of poor differentiation of tomato buds, poor pollination during flowering or incomplete pollination and fertilization, and these fruits with poor pollination and fertilization quality will be prone to the development rate of epidermal pulp cells and the development rate of internal cavity cells when they are expanded in the later stage, which will lead to the appearance of tomato hollow fruits and concave convex fruits.
The fifth reason: it is related to improper fertilization and watering during the growth period of tomatoes. If the tomato is not fertilized enough during the flowering and fruiting stage, especially in the case of too much nitrogen fertilizer and insufficient potassium fertilizer, or if the soil is dry and water-scarce during the tomato fruiting stage, this will also cause the tomato to be inhibited and the fruit to develop poorly and appear cavities and convex hollow fruits.
The sixth reason: it is related to the improper dipping of tomato liquid. Although it is said that the medicinal liquid dipping flower can improve the fruit setting rate of tomatoes, if the concentration of the dipping anther solution is too high (such as the use of anti-fallin, 2, 4-D, etc.), it will cause the placenta of the tomato young fruit to be poorly developed, the ovary is not fully developed and there are cavities, convex edges and other deformed fruit problems.
