What are the precautions for growing cherries in greenhouses

Cherries are grown in the open field in many places, but cultivating cherries in greenhouses can make them ripen earlier, come to market earlier, and generate revenue, so many growers choose to grow cherries in greenhouses. So what should be noted when growing cherries in greenhouses? Let's take a look at the detailed introduction.

1. Late fruiting

Greenhouse management is more complex than open-field management and requires growers to be careful. Cherry trees grow quickly, but their growth period is relatively long. Generally, after planting, they need 4-5 years of cultivation before they bloom and bear fruit, and the yield is relatively low. During this period, management must be strengthened so that they bloom and bear more fruit. Many fruit growers cannot wait this long, lose confidence in management, and let the trees grow however they want, forming a vicious cycle and causing many fruit trees to grow poorly or die. Therefore, to improve cherry cultivation in greenhouses, it is necessary to overcome this long waiting period and remain confident at all times.

2. Crown gall disease

Crown gall is the cancer of fruit trees. It occurs when bacilli in the soil invade root tissue cells, causing chromosomal variation in the cells, leading to uncontrolled cell division and the formation of root galls. This is a disease that seriously harms the root system. Once it breaks out, it is extremely difficult to control, until the fruit tree dies. Another cause of crown gall is that purchased seedlings carry crown gall pathogens, or the planting soil contains pathogens left by the previous crop. In addition, slightly alkaline soil can also induce this disease. The greenhouse environment is more conducive to the growth and reproduction of crown gall pathogens, and the incidence of crown gall is higher in greenhouse cultivation than in open-field cultivation, so special attention must be paid.

3. Pollination problems

In production, cherries mostly rely on cross-pollination. The reason many cherry trees do not bear fruit is poor pollination during the flowering period. Greenhouse cultivation is a relatively closed environment, and pollen cannot be spread by wind or other factors for pollination, often resulting in poor pollination and low yields. Therefore, in this situation, artificial pollination should be done well, and bees can also be placed in the greenhouse to assist pollination.

4. Lack of supporting technical measures

In the development process of cherry cultivation, there are still many drawbacks and technical misunderstandings. If planting is carried out according to standardized procedures, strict quarantine measures should be applied to seedlings, and substandard seedlings must be strictly prohibited from leaving the nursery. In newly built orchards, a certain number of pollinating varieties should be configured, and their flowering period must be consistent with that of the main cultivated variety. At the same time, varieties suitable for the local area should be selected according to local conditions.
