Planting time and method of pear tree

The planting time of pear trees can be planted from September to November or from February to May, and the specific planting time can be determined according to the variety habits of pear trees and the local climatic environment. Pear planting method: choose good drainage and irrigation conditions, deep soil layer, loose and fertile soil to plant, seedlings should choose no damage, disease-free, robust seedlings for reasonable close planting. Adequate base fertilizer should be applied before planting, and attention should be paid to topdressing, pruning branches and controlling diseases and insect pests during the growing period.

I. planting time of pear trees

Pear trees can be planted from September to November or from February to May. The specific planting time is determined according to the local climate and environment, and the variety habits of pear trees can also determine the planting time.

II. Soil requirements

It should be planted in the soil with deep soil layer, good drainage and irrigation conditions and loose and fertile soil. Before planting, it is necessary to dig a planting pool of about 1m in length and width, and then apply a sufficient amount of base fertilizer in the pond, and then cover a layer of fine soil.

3. Selection of species

Select disease-free, damage-free, robust seedlings for planting, and then put the seedlings vertically into the planting pool, soil cultivation, watering, must be reasonable planting density, general plant spacing is 2m, row spacing is 3m.

IV. Rational water and fertilizer

The main results are as follows: 1. Sufficient base fertilizer should be applied before planting, and appropriate amount of topdressing should be applied in the later stage, especially nitrogen fertilizer can be applied in the early stage, which is beneficial to promote the growth rate of pear trees.

2. In order to supplement the nutrients needed for plant growth from post-anthesis to flower bud differentiation, compound fertilizer should be applied, while during the fruit expansion period, potash fertilizer and appropriate amount of phosphate fertilizer can be applied, which is beneficial to the rapid expansion of fruit.

3. Pear trees are more drought-tolerant and can be watered once after each fertilization.

5. Shaping and pruning

1. Proper shaping and pruning is beneficial to plant growth, blossom and fruiting, thus increasing yield.

2. Pruning and shaping can be carried out when the seedlings grow to 70-80cm. Pruning buds is beneficial to promote branching and thus accelerate the formation of tree crown.

3. when the tree shape has been formed, it is necessary to cut off the overdense big branches, overgrown branches, disease and insect branches, and ineffective branches, and more auxiliary branches should be left.

4. Secondly, in order to ensure a certain amount of fruit, it is necessary to increase fertilizer at flowering stage and artificial pollination is needed to increase yield.

VI. Prevention and control of diseases and insect pests

1. Disease

Diseases and insect pests will affect the yield of pear trees to a certain extent. the common diseases of pear trees are rust, powdery mildew and ring disease, which mainly harm the leaves and fruits of the plant, affect the normal growth and development of the plant, and lead to less flowering and fruit. in serious cases, it can also lead to plant death.

Prevention and control methods: pesticide control can be combined with chemical control, disinfect the seedlings and soil before planting, and then spray chemicals for control.

2. Insect pests

The common pear pests are aphids, pear heart borer, pear stem wasp, pear planthopper and so on, which mainly harm the branches and leaves of young parts and eat plant parts, thus affecting plant growth and reducing yield.

Control methods: remove weeds and debris around the plant before overwintering, so as to reduce the source of insects, and can be sprayed when the disease occurs.
