What should be noted when growing pear trees in summer? Please go through them one by oneWhen growing pear trees in summer, the following main points need attention:
1. Soil, fertilizer and water management
The principle of fertilizer and water management for pears is to increase fertilizer and water in the early stage and control growth in the later stage. Before July, increase fertilizer and water to promote branch growth and young fruit development. After July, apply compound fertilizer, and generally no longer apply nitrogen fertilizer, focusing on controlling growth to promote fruit development and flower bud differentiation.
2. Summer pruning
Summer pruning is mainly for improving light exposure. Pear branches grow upright, so ventilation and light penetration are poor. Branches can be bent appropriately, with a bending angle of 45° being suitable. Overly dense branches and upright branches on the upper side can be thinned out. Lateral branches can, depending on space, be pinched in time or pinched multiple times when they should not grow too long, to promote the formation of lower flower buds. For competing branches, control growth by pinching or bending to promote the growth of main branches. For young trees with too few branches, increase fertilizer and water and pinch the tips to promote branch sprouting and expand the canopy. Note: Moderately ring-barking Emerald pear in early June can significantly increase the flowering rate.
3. Spraying and bagging
For pear trees that have already entered the fruiting stage, spray and bag in time. The bagging time is determined at 20-30 days after petal fall. Before bagging, first thin the fruit and spray 1 application of a highly effective, low-toxicity insecticide and fungicide to control pear psylla and diseases. After bagging, spray an insecticide and fungicide once every 10-15 days to protect the leaves. For Golden pear, promote double bagging, with the second bagging done one month after the first (around late June).
