When the pear blossoms, the management points before and after the pear blossoms.

As the saying goes, "Spring flowers and autumn pears", we can not only enjoy the magnificent scenery of pear trees in spring, but also taste the delicious fragrant pears in autumn. Pears are very popular in autumn. They are sweet and delicious, which can reduce the dryness in autumn. Due to the great market demand, more and more people are now planting pears. When do pears bloom? What are the management points before and after pear blossom? Let's find out.

When does the pear tree blossom?

The flowering time of pear trees is mainly from March to May every spring. However, it should be noted that the flowering period of pears is closely related to factors such as region and temperature. In northern China, the weather is cold and flowers usually bloom after mid-April. In some high altitude areas, flowers bloom around May. The climate in the east is more suitable, and pear trees in some areas can bloom in early March.

Erase the bud

Strong buds on the back of main branches and auxiliary branches, buds near the incision after cutting strong branches, long branches on the back of main branches, short fruit branches and residual branches after cutting long branches should be removed as soon as possible.

flower thinning

When the bud is exposed, press the bud with your fingers from top to bottom, and the pedicel will break. The standard of sparse bud is to leave an inflorescence every 20 cm, which should be weak but not strong, small but not big, dense and not sparse, low and not high. In addition, after the inflorescence is elongated, the accessory inflorescence should be removed in time to maintain normal flowering.

fruit thinning

After the flower withers 10- 15 days, 1-2 fruits are left in each inflorescence, and the redundant fruits are removed. When thinning fruit, we should first remove diseased fruit, deformed fruit, deformed fruit and leafless fruit. At the same time, young fruits with long fruit shape, long and thick fruit handle and smooth fruit surface are selected. According to site conditions, fertilization level, tree size, tree potential and other factors to determine the fruit yield.

Pollination and branch hanging

Artificial pollination can not only improve the fruit setting rate, but also effectively improve the big fruit rate and quality. For a single variety of pear orchards, in order to solve the pollination problem, pollinated buds can be inserted into water tanks or plastic bags (cups) and hung on trees. Generally speaking, a big tree needs to hang 4-5 pots.

Re-cutting at flowering stage

Pear trees can also be pruned before flowering to make them blossom and bear fruit better. Under normal circumstances, when there are many flowers on the pear tree, you can cut off the weak branches or diseased branches. Then, cut the bud very thin and keep the bud growing well, so as to achieve better results.

plant diseases and insect pests

The main pests and diseases are scab, black spot, rust, pear lice, pear moth, nettle mite and so on. And not at the beginning of flowering, but 2-3 times after flowering, once every 10- 15 days.

As the saying goes, flowers bring fruit. Attention must be paid to the management of pear blossom period. If left unchecked, it is easy to cause the phenomenon of full flowers and half fruits, which will affect the fruit setting rate. In addition to the above measures, fertilization, antifreeze and other work should also be put in place, which is conducive to the flowering and fruiting of pear trees.
