Causes of fruit cracking of latest apricot trees and preventive measures

Apricot fruit cracking is a common problem in apricot cultivation, which will not only reduce the commodity value of fruit, but also bring huge economic losses to farmers. Most of the fruit with the top as the center extends radially to the carcass and shoulder, and some will crack from the suture line to the core, so what is the cause of fruit cracking in apricot trees? How to prevent it? Let's take a look.

1. Variety reasons

Because the varieties of apricot trees are different, the probability and degree of fruit cracking are different, in which large and medium-sized fruits are easier to crack than small fruits, oblate fruits than round fruits, and early-maturing fruits are easier to crack than late-maturing fruits. When it rains during the ripening period of apricot, the varieties with thin skin and soft texture are also easy to crack fruit.

Preventive measures: suitable varieties should be selected according to local climate conditions, and it is recommended to choose crack-resistant varieties with early or late maturity, good pulp elasticity and low plasticity, such as rhubarb, Erhong, red apricot and so on.

2. Improper soil

The growth and development of apricot has certain requirements for the soil. If it is planted on the land with heavy soil texture, then the phenomenon of fruit cracking of apricot is very common, which is caused by the drastic change of dry and wet clay.

Preventive measures: therefore, land should be selected before planting, loose and fertile sandy loam should be selected as far as possible, and soil structure can also be improved by improving soil and applying organic fertilizer to increase soil permeability and water retention, so as to make soil water supply uniform and reduce the possibility of fruit cracking.

3. Too much water

In the apricot fruit ripening period, if there is continuous rainy weather, or long drought and rain and flood irrigation, it will cause a large amount of fruit absorption and cause fruit cracking, so if there are more Rain Water in many areas, the fruit cracking phenomenon will be more serious.

Preventive measures: apricot trees are not resistant to waterlogging, so it should be drained in time in Rain Water, otherwise it will not only cause fruit cracking, but also cause root rot due to stagnant water. In drought, it is necessary to timely watering, drip irrigation or sprinkler irrigation is the best, not flood irrigation, especially in the fruit ripening period, to prevent the soil from being too dry or too wet.

4. the cause of fruit growth.

Apricot begins to crack in the second fast period, especially in the coloring period, when a large amount of soluble sugar is transformed and accumulated, and the pressure tolerance of the pericarp decreases. If drought and rainfall for a long time, the pulp is absorbed too much, the pericarp is split directly, resulting in fruit cracking.

Preventive measures: it can be treated with chemicals or growth regulators, and rare earth solution or naphthylacetic acid solution can be sprayed once during fruit expansion and coloring period, which can obviously reduce the phenomenon of fruit cracking.

The above is the introduction of the causes and preventive measures of apricot fruit cracking. I hope it can help you. If you want to know more about it, please follow us.
