Causes and preventive measures of out-of-season flowering of pear trees

Pear is widely distributed all over the world, and its cultivated area and yield are second only to apples in our country. It is one of the common fruits in our life. However, in the process of pear cultivation, the phenomenon of out-of-season flowering is very easy to occur, which often causes huge losses to fruit growers, so what is the reason for pear out-of-season flowering? How to prevent it? Let's take a look.

1. Reasons for out-of-season flowering

The off-season flowering of pear trees is mainly caused by three reasons: first, extensive management, resulting in less accumulation of nutrients and a decline in stress resistance; second, suffering from diseases and insect pests, resulting in early defoliation Third, under the influence of high temperature or continuous overcast and rainy weather, the flower buds that have finished flower bud differentiation in June or September are dormant without low temperature, and will continue to sprout in autumn at a suitable temperature, so the phenomenon of out-of-season flowering occurs.

II. Preventive measures

1. Strengthen the management of fertilizer and water

Increase the application of organic fertilizer, improve soil structure, increase the supply of nutrients to trees, generally apply high-quality base fertilizer 70-100 kg per plant. Foliar fertilizer was sprayed 3-5 times during the growing period to prolong leaf life, increase photosynthesis and complete nutrient accumulation. Irrigation should be done in time during drought, drainage should be done well in rainy season, irrigation should be paid attention to before fruit picking, and generally should be watered once every 7-0 days during drought, which is helpful to improve yield and quality.

2. Reasonable pruning

In the growing period, it is necessary to prune the shaded branches, disease and insect branches, withered branches and weak branches, enhance the permeability of the plant, cultivate excellent fruiting branches, thinning flowers and fruits appropriately in the flowering and fruiting stage, and maintain a reasonable load on the tree. Pruning should also be carried out in fruit harvest to avoid excessive consumption of nutrients and promote sprouting in the coming year.

3. Remove buds and young fruits

For pear trees with out-of-season flowering or young fruit, the buds and young fruits should be removed in time to save tree nutrients, increase the accumulation of tree nutrients, and avoid indifferent consumption.

4. strengthen the prevention and control of diseases and insect pests

The prevention and control of diseases and insect pests should follow the principle of prevention and comprehensive control, understand the law of the occurrence of diseases and insect pests, and adopt the strategies of agricultural control, physical control and biological control, supplemented by chemical control. For the prevention and control of diseases and insect pests early, chemical control should be taken to pay attention to, in the first half of the fruit should not be applied, so as not to produce drug residues in the fruit.

The above is the introduction of the reasons and preventive measures for the off-season flowering of pear trees. I hope it can help you. If you want to know more about it, please follow us.
