What is the cause of tomato cracking?

Tomato cracking is a common disease at present, many farmers report that their tomatoes are inexplicably cracked, and they do not know the reason. In fact, fruit cracking is generally caused by the following reasons, let's take a look at these reasons.

1. Temperature instability

Excessive changes in temperature can easily cause fruit cracking, both in the open air and in the greenhouse. The open air often occurs at the time of the alternation of seasons, and the greenhouse is mostly caused by the lack of control during the release. When the temperature is unstable, the skin of the tomato will become very brittle, in a tight state, not as elastic as normal, when the tension can not stop, the fruit will naturally crack.

2. Weather change

Weather changes can also be a common cause, such as when the weather is dry for a long time and then suddenly rains for a period of time. This is because in the process of growth, the growth rate ratio of tomato peel to pulp is broken, the two are balanced growth, this is the pulp growth rate is much faster than the pericarp, and finally naturally split the fruit. This often happens when the rainy season comes.

3. Transition from fertilizer to fertilizer

Fertilizer for tomatoes is not the more the better, the need for the right amount, such as nitrogen fertilizer can easily lead to tomato fruit cracking. Nitrogen fertilizer mainly promotes the growth of tomato pulp, when too much nitrogen fertilizer will lead to pulp growth too fast, while nitrogen fertilizer for promoting the growth of the peel is not obvious, and finally lead to the peel can not keep the pulp, and then into the formation of cracking fruit. When you touch the peel of some tomatoes, you should be careful to crack the fruit.

4. Improper use of drugs

Medication is also a factor that can easily lead to fruit cracking. Tomatoes encounter a lot of diseases every day, and growers generally use drugs to solve them. When the drug concentration is too high, it will lead to fruit cracking. The concentration of some drugs will inhibit the growth of the pericarp, and even cause the pericarp to atrophy and lose elasticity, but the pulp will not shrink, and finally the pericarp will crack when it is stretched to the limit. Therefore, when using medicine, be sure to follow the instructions to get the configuration.

These are some of the reasons for tomato cracking. You can see if your own fruit cracking is caused by the above reasons. If so, you'd better adjust your planting method properly to prevent fruit cracking.
