Pear is a light-loving tree, and the annual sunshine hours need 1600~ 1700 hours. In a certain range, with the increase of sunshine hours and light intensity, photosynthesis is enhanced. Therefore, determining planting density, choosing a good tree shape, controlling tree height and crown width, and maintaining a certain branch density per unit area are all requirements for maintaining good ventilation and light transmission conditions of pear trees.

However, if the cultivated pear trees are grafted saplings, the fruiting period will be advanced accordingly, but the specific time for pear trees to bear fruit depends on the age of pear trees. Basically, when it is big enough, the pear tree will bear fruit.

In the second year, promote branches and expand crowns. In spring, take off the cold-proof materials and prune them, and then continue to do a good job in field management such as intercropping, weeding, topdressing outside the roots, controlling pests and diseases, applying base fertilizer and pulling branches. Orchards with conditions can be planted with grass. The root system of pear began to move above 0.5℃, and new roots appeared at 6-7℃. Flowering requires the temperature to be stable above 10℃ and reach 14℃. The flowering is accelerated, and the temperature above 20℃ is needed for fruit development and flower bud differentiation.

If the water and fertilizer can keep up in the first year, there will be flowers and fruits in that year, but you will pick them and not let them tie. You can hang a small amount of fruit in the second year. In the third year, it began to bear fruit formally, because the owner of the small orchard would not let it bear too much fruit, and it began to enter the prosperous fruit period five years later. At least five years, and there must be pear trees around. Pear trees are pollinated by bees, flies, beetles and various birds! Flies pollinate more! Don't kill flies in pollination season! Pollinated fruit can be bagged in a ping-pong bag to prevent fruit flies and Blackstone bacteria!

Peach, apricot and pear for five years: my wife spent money on pear trees that year, especially in three or four years. Strengthening the management of pear trees: winter pruning is mainly like summer pruning, especially summer pruning: falling heart, twisting branches and ring cutting: after the three technologies are determined, the results of pruning are used. After the temperature of the trees is determined, a lot of results begin. On the basis of general management, in order to make the new orchard put into production as soon as possible, it can be considered to be dense first and then sparse.
