In summer, the temperature is high and there is much rain. What should pear trees pay attention to in summer?

Transplanting pear trees in summer is more complicated, and the survival rate is not high, because of the large evaporation and less nutrients stored. Transplant pear trees about a week after defoliation in autumn or about half a month before germination in mid-March in southern Shandong in spring. Rootstocks are usually made of sweet pears or yamanashi. Generally, intermediate dwarfing rootstocks are warm. Under the action of dwarf rootstock, the growth of dwarf pear varieties is restricted and dwarfed, which is convenient for production management and farming operation, and makes the fruit develop rapidly, with good uniformity and uniform size.

Pruning should be carried out reasonably in the fourth winter and growing season, so as to keep the balance of tree potential, strive for reasonable size distribution and even distribution of fruiting branches. Adjust the lighting conditions in the cave. Strive to create a balanced tree structure with weak external strength and strong internal strength. Pear trees have a great influence on fruit drop and are planted in different climatic environments. However, in order to ensure the good effect of pear cultivation and obtain good economic benefits, we should try our best to stay away from pollution sources and thinning branches in the process of pear plantation site selection.

Also known as thinning, that is, cutting annual or perennial branches from the base. Suitable for trees with closed crown, poor ventilation and light transmission, and secondary branches or dense branches competing for cutting. Thinning branches is beneficial to enhance the ventilation and light transmission conditions of the crown. In summer, pear trees are luxuriant in branches and leaves, and the fruit light is easily blocked. This kind of pear is small in size and low in sweetness. We remove dense branches, increase ventilation and light transmission, improve the closed environment of pear branches, and thus improve fruit quality. Pruning pear trees is common in summer. Although some growers prune pear trees in summer.

But they don't know the benefits and precautions of pruning pear trees. I answer two questions in two parts. The principle of pear fertilizer and water management is to increase fertilizer and water in the early stage and control growth in the later stage. Fertilizer and water should be increased before July to promote the growth of branches and young fruits. After July, compound fertilizer should be applied instead of nitrogen fertilizer, mainly to control growth and promote fruit development and flower bud differentiation. Some farmers think that pear trees can be pruned at any time according to the situation, which is a typical misunderstanding. Let's talk about the usual practice first. Pruning of pear trees is usually carried out in summer.
