Management skills of dormant period of planting pear trees

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

Cultivation measures

Through winter pruning, we can improve the ventilation and light transmission conditions of pear trees, adjust the balance between root system and branches, growth and development, and retain strong branches and reasonable flower branches, so as to create conditions for high quality and high yield of pear trees.

Pest control

Measures taken during the dormant period can reduce the base of diseases and insect pests and reduce the number of chemical medication, which is particularly important for the production of reassuring fruits.

1. Clear the orchard to clean up the fallen leaves, residual branches and fallen fruits in the orchard, and classify them as soon as possible. Fallen leaves can be used as raw materials for high-temperature composting, and residual branches and fallen fruits can be used as fuel or buried deeply. Through clearing the garden, a large number of pear planthopper, stink bugs, brown rot, scab, ring rot and other diseases and insect pests overwintering on leaves, branches and fruits can be eliminated.

two。 Scrape the bark to scrape off the thick warped bark and ring disease on the branches of the pear tree, and take the scraped bark and the diseased tumor out of the orchard and destroy it centrally. In this way, it can not only promote the growth and development of trees, but also eliminate diseases and insect pests such as ring disease, rot, pear planthopper, pear heart borer, Hawthorn red spider and so on.

3. The cutting blade with large protection should be smeared with Hubiqing or 343 rehabilitation agent to prevent and control bacterial infection.

Establishment of orchard

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

Strengthen monitoring

1. Carry on the environmental monitoring to the newly-built pear orchard to ensure that it meets the environmental requirements of rest assured fruit production, monitor the existing pear orchard, maintain and improve the ecological environment of the pear orchard.

two。 Monitor agricultural activities to ensure that they are managed in accordance with the rules of safe fruit production, with emphasis on monitoring the role of pear orchard remover.

3. The growth status of pear trees was monitored, with emphasis on the quality of pear pruning in winter.
