How to manage pear trees during the dormant period? A full explanation of practical tips

The dormant period of pear trees is generally from December of the previous year to February of the following year. During this time, pear trees are in a state of natural or forced dormancy, and most pests and diseases are also in a dormant state.

Cultivation measures

Through winter pruning, improve the ventilation and light conditions of the tree canopy, regulate the balance between the pear tree root system and branches and trunk and between growth and development, retain strong branches and strong flower buds and a reasonable number of flowering branches, and create conditions for high-quality and high-yield pear trees.

Pest and disease control

Taking measures during the dormant period can reduce the base number of pests and diseases, reduce the number of chemical applications, and is especially important for producing fruit.

1. Clean the orchard: clean up fallen leaves, residual branches, fallen fruit, etc. in the orchard, and sort and handle them as soon as possible. Fallen leaves can be used as raw material for high-temperature composting, and residual branches and fallen fruit can be used as fuel or buried deeply. Through orchard cleanup, a large number of pests and diseases that overwinter on leaves, branches, fruit, etc., such as pear psylla, stink bugs, brown rot, scab, and ring rot, can be eliminated.

2. Scrape tree bark: scrape off the coarse old cracked bark and ring rot tumors on pear tree branches and trunks, and take the scraped bark and diseased tumors out of the orchard and destroy them in a centralized manner. In this way, the growth and development of the tree can be promoted, and pests and diseases such as ring rot, rot disease, pear psylla, pear fruit borer, and hawthorn red spider can also be eliminated.

3. Protection of pruning and saw cuts: large pruning and saw cuts should be coated with Fubiqing or 343 rehabilitation agent to prevent pathogen infection.

Orchard establishment

Choose a suitable site, do a good job in orchard planning, prepare high-quality seedlings, and it is best to plant trees in autumn.

Strengthen monitoring

1. Conduct environmental monitoring for newly built pear orchards to ensure they meet the environmental requirements for fruit production, and monitor existing pear orchards to maintain and improve the pear orchard ecological environment.

2. Monitor agricultural activities to ensure management is carried out according to fruit production regulations, with emphasis on monitoring the effect of eradication agents in pear orchards.

3. Monitor the growth status of pear trees, with emphasis on monitoring the quality of winter pruning of pear trees.
