Cultivars have 3-5 styles, 3-5 chambers, and each chamber has 2 ovules.

Flowering management: Flowering management of pear trees is very important. It takes flowers to get fruit. Improper or negligent management of pear flowering period is prone to the phenomenon of full flower and half fruit, low fruit setting rate and low economic benefit. Adopting the following methods to strengthen the management of pear flowering period can improve the fruit setting rate, fruit quality and economic benefits.

Topdressing before flowering: Topdressing before flowering can improve the quality of flower buds, meet the nutrition consumed by flowering and improve the fruit setting rate. Quick-acting fertilizer, mainly compound fertilizer, can be applied in the first half of the flower. Generally, 0.5- 1 kg is applied to each adult tree, and 1-2 kg of urea can be added to weak trees, and the fertilizer application amount should account for 10- 15% of the whole year.

Pruning before flowering: pear trees with light pruning and large flowers should be pruned again, mainly to remove weak branches, diseased dead branches and over-dense branches, adjust the load of fruit trees, and determine the amount of flowers according to the amount of fruits left. Generally, the amount of flowers left is 65,438+0-2 times more than the amount of fruits left, and only 65,438+0 flower buds are left on each fruit table to remove redundant flower buds, which is responsive to pruning.
