The Latest Guide to Pear Tree Blooming Period Management Techniques
Pears are a common fruit in our daily lives, and there are many varieties of pears. There is also a very large planting area in our country now. When growing pear trees, we need to adjust management methods according to the growth stages of the pear trees. Especially during the pear tree blooming period, management must be strengthened. So how should pear trees be managed during the blooming period? Below, the editor brings you pear tree blooming period management techniques. Let's take a look!
1. Bud removal
Pear trees begin to sprout after entering spring. By the blooming period, the new buds on the pear trees have basically all sprouted. However, there will also be some buds that sprout later, causing them to still not have sprouted during the blooming period. Therefore, such buds must be removed in time, because sprouting too late will affect the flowering of the pear trees. Moreover, these buds will also consume the nutrients of the pear trees, leading to higher planting costs and reducing the fruit-setting rate of the pear trees. So we should often observe the sprouting situation of the pear trees, and if there are such buds, remove them in time.
2. Artificial pollination
The natural pollination rate of pear trees is relatively low, and if special situations such as rainy days occur, the pollination rate will be further reduced, leading to a decline in the fruit-setting rate. This causes pear trees to show the phenomenon of alternate bearing. Therefore, during the pear tree blooming period, we must also do a good job of artificial pollination. Reasonable pollination can not only improve the flowering and fruiting rate of pear trees, but also effectively avoid the phenomenon of alternate bearing. To ensure that the yield remains stable every year, it should generally be carried out within one week after the blooming period. Tools such as writing brushes and feather dusters can be used for artificial pollination, and bees can also be released in the orchard to let bees assist pollination.
3. Reasonable flower protection
The fruit-setting rate of pear trees is relatively low, generally because the number of flowers is too small. To improve the fruit-setting rate, we must also do a good job of flower protection to avoid flower drop. Before flowering, appropriate topdressing should be applied to enhance flower quality and meet the nutritional needs of pear trees for flowering. About two weeks before flowering, an appropriate amount of compound fertilizer can be applied; for adult trees, about 1 kg can be applied, and if the growth is weak, about 1.5 kg of urea can be applied. Then an appropriate amount of flower-protecting agent should be sprayed to reduce flower drop. However, the number of flowers should not be too large either. For pear trees with a relatively large number of retained flowers, pruning again and flower thinning should be done well to prevent excessive nutrient consumption.
4. Frost prevention
The flowering time of pear trees is relatively early, generally mostly during late frost, so during the pear tree blooming period the flowers are extremely susceptible to damage from late frost. If frozen, the stamens of the pear tree flowers will turn brown and gradually shrink and dry, and although they can bloom, they cannot bear fruit. Therefore, we must do a good job of frost prevention. Before flowering, appropriate watering can lower the ground temperature, inhibit root activity, and delay flowering time, which can effectively reduce late frost damage. Before flowering, the trunks of pear trees can also be whitewashed to raise the tree body temperature and delay the blooming period by about 4 days. Then smoke fumigation for frost prevention is also a main measure for frost prevention in pear trees, as it can both raise the ground temperature and allow smoke particles to absorb moisture.
The above is a brief introduction to pear tree blooming period management techniques. That is all for today's introduction. This article is for reference only, and we hope it can help everyone!
