Grafted cherry trees bear fruit for several years

Cherry is a kind of expensive fruit with red and bright color, exquisite as agate gemstone and sweet taste. Many people start to plant cherries, so do you know the fruit of grafted cherry trees for a few years?

1. Grafting cherry tree for several years

Grafted cherry trees usually bear fruit in 3-5 years, but 2-3 varieties of cherries grafted on a tree can bear fruit normally. Cherries grafted with only one variety may not bear fruit, so be careful when grafting.

Cherry tree is a strict cross-pollination plant, most big cherry varieties, self-pollination can not bear normal fruit, need to plant 2-3 varieties to pollinate each other in order to bear normal fruit.

2. Cultivation techniques

If the main varieties and pollination trees are equipped with cherry self-flowering and non-fruiting, pollination varieties with the same florescence and strong affinity must be configured. Planting period: it can be planted before and after falling leaves in autumn to before sprouting in spring of the following year, and it is suitable to be planted in autumn.

The planting density is determined according to the climate, soil, water conservancy and topography, variety characteristics, dwarfing ability of rootstocks, shaping and pruning methods and overall management level of cherry orchards.

Fertilizer and water management fertilization: young trees and primary fruit trees, mainly applying sufficient basic fertilizer; young trees topdressing 1-2 times of nitrogen fertilizer, primary fruit trees can be forced to apply nitrogen and phosphorus fertilizer 3-4 times a year. Fruit trees are usually fertilized four times a year.

Application of base fertilizer in autumn: it is carried out in combination with deep turning and expanding acupoints from September to October every year. Postharvest water: after fruit harvest, it is an important period of tree restoration and flower bud differentiation, this watering should be controlled, less rather than more, combined with fertilization for irrigation to lay the foundation for high yield in the coming year. Frozen water: from defoliation to soil freezing, to keep the soil temperature and humidity relatively stable and protect the roots from freezing damage.

Shaping and pruning spindle shape: dry height 40-60cm, tree height 3-4m. There are 10-15 main branches in whorls on the central trunk, and the opening angle is 70 °- 80 °.

The small crown has a central trunk with a height of 40-50cm, and the whole tree has 5-6 main branches, which are divided into two layers with a layer distance of 120-150cm.

Trim. Young tree stage: cultivate the tree skeleton and enlarge the crown. Suppress the strong and help the weak, so that there is a clear distinction between the master and the subordinate and a clear level.

Artificial pollination: at flowering stage, bell buds are collected from pollinated varieties to make mixed pollen, and artificial pollination is carried out at the early flowering stage and full flowering stage, or at 10:00-17: 00:00, a chicken feather duster is used to roll on different varieties of trees. for artificial pollination.

Cherry is more stringent on the environment, so the yield of planting is relatively small, so you should consider carefully when planting.
