According to TCM syndrome differentiation, jujube will crack when it rains in mature season. How to prevent cracking by TCM syndrome differentiation?

First, the physiological harm caused by excessive temperature difference.

Second, the water and fertilizer are unreasonable, and the strong sunlight after rain can easily lead to fruit cracking.

Third, high maturity is easy to cause fruit cracking.

Fourth, some varieties have poor adaptability to the outside world and are easy to crack.

Five, excessive hormones, improper use caused by the physiological harm of cracked fruit. Jujube is a common fruit in daily life, which is not only of high nutritional value, but also a beauty product in women's hearts. It is precisely because jujube has good market economic value that jujube trees are planted in many places in China. When it comes to cracked fruit, people are unlikely to think of jujube trees, but citrus, grapes, grapefruit and so on. Many people want to know, like jujube trees, the fruit is not small, the water is not much, and the skin is not thin. Why do fruits crack? Let's get to know each other.

First, the causes of jujube fruit cracking

Theoretically speaking, jujube trees will not crack easily, because jujube trees are drought-resistant and waterlogged-resistant, adaptable and easy to cultivate. However, for many novices, because the planting technology is not in place, it is easy to have various management loopholes, so the phenomenon of fruit cracking will occur. There are three reasons for jujube fruit cracking:

The first is the variety. Like other fruit trees, the biggest cause of fruit cracking is the variety problem. Generally, varieties with thin or loose peel and large intercellular space are easy to crack, such as Dongzao, Hupingzao, Lizao and Jinsixiaozao.

Second, environmental reasons. Environment is about the external environment, such as soil, light, moisture and so on. When these external environmental conditions are not enough to meet the growth needs of jujube trees, fruit cracking will occur.

Third, management reasons. In fact, whether it is a variety problem or an environmental problem, if we do our best in management, we can also avoid fruit cracking. However, if management is not in place, it is another matter. If fertilization is improper, there is too much water or the soil is not turned deep, jujube fruit will naturally crack.

Second, methods to prevent cracking of red dates

1. Water and fertilizer management

Fertilizers are relatively simple. Applying base fertilizer in autumn and topdressing according to phenology is nothing worthy of special attention. "On the contrary, water management is relatively important, because a large part of the causes of fruit cracking are mainly caused by water. Therefore, attention should be paid to the drainage of jujube orchards in rainy season and the irrigation of jujube orchards in dry weather. During the expansion period of jujube fruit, attention should be paid to keeping the soil moist to avoid being too wet or too dry.

Remodeling and pruning

Generally speaking, under the condition of good ventilation and light transmission and sparse branches, the probability of fruit cracking in jujube orchard will be greatly reduced. Therefore, reasonable pruning is very important, especially in winter. The main purpose of pruning in winter is to remove some big branches in the middle, increase the opening angle of branches and cut off some old branches, which can not only improve the ventilation and light transmission conditions, but also reduce the loss of nutrients.

Timely harvest

Pay close attention to the weather forecast after entering the white ripe period and crisp ripe period. If it doesn't rain, we should collect jujube fruits for different purposes at normal time. Because if the weather changes greatly, it is dry and rainy during this period, it is easy to crack the fruit, so it needs to be harvested in time. If this period coincides with the rainy season and cannot be collected in time, hormones can be sprayed to avoid the rainy season.

The above are the reasons and prevention methods of jujube fruit cracking, I hope it will help you.
