Latest Key Points of Autumn Management Techniques for Pear Trees
Pears are a fruit that many people enjoy eating very much, and they are grown on a very large scale in our country. When we grow pear trees, we need to do a good job of management according to the changes of the seasons. Because the climate changes greatly in each season, the growth of pear trees will also be affected to a greater or lesser extent. So how should pear trees be managed in autumn? Below, the editor will give everyone a brief introduction, let's take a look!
1. Applying base fertilizer in autumn
In autumn, the first management task we need to do well is applying base fertilizer. Base fertilizer should generally be applied in August-September, in which nitrogen fertilizer must not be too much, and the proportion of potassium fertilizer should be appropriately increased. When applying base fertilizer, it should be combined with deep plowing and hole expansion. It is mainly based on decomposed farmyard manure, with the amount per pear tree kept at about 60-80kg, combined with an appropriate amount of compound fertilizer, and after application, water and cover with soil. Then we should also prune the roots to cut them, and the depth of the fertilization ditch should be about 10cm deeper than before, to ensure balanced growth of the pear tree.
2. Branch bending and branch hanging
When managing pear trees in autumn, we should also do a good job of branch bending and branch hanging. Branch bending can allow young trees to form their crowns earlier, allow pear trees to sprout earlier and increase the amount of sprouting, and prevent excessive vegetative growth of pear trees. It should generally be done after the pear trees lose their leaves in autumn. For 2-3 year old pear trees, the branches to be bent should mainly be the main branches, extension branches, and secondary main branches. The main targets for branch hanging are drooping branches, because if drooping branches bear too much fruit, they are prone to splitting. Therefore, we can tie long rafters to the central leader, and then tie the fruiting branches of the pear tree to the rafters.
3. Timely harvesting
Autumn is the season when pear tree fruits mature, so our harvesting work is also very important. When harvesting in autumn, we should pay attention to various factors such as the characteristics of the pear tree variety, the time to market, the marketing location, and storability. Choose the appropriate maturity time for the pear fruit to harvest, and never harvest too early. And when harvesting, it should be done in batches, which can improve the quality and commercial value of the pear fruit. Therefore, when harvesting the fruit, we should first finish picking the fruit on the outer part of the tree and the lower part of the crown. Then harvest the fruit on the upper part of the crown and the inner part. Generally, it is best to finish picking in three times, with each time kept at about 5 days.
4. Pest and disease control
Many fruit growers do not pay attention to pest and disease control work after the pear tree fruits are harvested. Pear trees lose their leaves relatively early, and in October, the phenomenon of a little Indian summer is likely to occur. Therefore, pear trees generally bloom in autumn, thereby affecting the yield of the next year. The main reason pear trees bloom in autumn is that they are troubled by pests and diseases such as black spot disease and pear psylla. So when there is relatively more rainfall in August-September, we should also pay attention to doing a good job of pest and disease control to ensure the growth of pear trees the following year.
The above is a brief introduction to how to fertilize pear trees in autumn. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
