Reasons for the flowering of pear trees in autumn and preventive remedies
In the autumn, the harvest of pear fruits generally ended, and many farmers misunderstood that the management work of one year after fruit picking was completed and management was abandoned. In fact, autumn management is very important, especially the quality of fertilizer management after fruit harvesting has a direct impact on the output of the following year, and relaxing management in the fall will easily lead to early deciduous pear trees. Pear tree deciduous is too early, so that pears are forced into early dormancy, met with sufficient water supply in the fall, the temperature is suitable conditions, dormancy is broken, some flower buds and buds germinate, there is the phenomenon of opening autumn flowers. Therefore, early deciduous pear trees are an important cause of autumn flowers in pear trees. Open autumn flowers are unfavorable for the growth of pear trees in the following year. Severe occurrences will result in a significant reduction in production or no harvest in the coming year.
Premature defoliation of pear trees is due to poor conditions of fertilizers and water, improper harvesting methods, etc., resulting in serious wilting of leaves. Pear trees are protected by their own, accelerate the formation of leaves from the leaves, thus leading to early defoliation.
The measures to prevent production loss are: timely fertilization before and after fruit harvesting. In case of high temperature and drought, timely irrigation, after the fruit is harvested, the prevention of pests and diseases is strengthened to protect the leaves, and the fruits are collected in batches, so that the nutrition of the tree body can be balanced and the pear tree nutrition can be prevented from generating defoliation.
The remedial measures after the opening of autumn flowers are timely picking flowers and picking shoots: the pear trees that have opened autumn flowers are cut off in time to remove flowering branches and leaves and reduce the nutrient consumption of the tree.
