High-yielding planting techniques of Pear

Pear is one of the three major fruits in China. Pear has a long history of cultivation and a wide range of distribution in China. Pear is also a favorite fruit. It is nutritious and can produce a variety of products in addition to raw food. It is an important export of our country. Most pears can bear fruit after planting in the same year, but the result in the second year is basically 100%, and the economic benefit is remarkable. The following pro-agricultural network brings high-yield planting techniques of pears.

1. Rational planting

Select the soil with deep soil layer, loose and fertile soil and good drainage. The planting time can be from September to March next year, or before November. Before planting, the planting pond should be one meter long and one meter wide, and then apply enough bottom fertilizer in the pond and cover it with a layer of fine soil. Select the seedlings with strong growth, no disease and no damage, put them vertically into the planting pool, and then cultivate the soil and water again. The planting should pay attention to the planting density and should not be too dense. Generally, the row spacing is 2 to 3 meters.

2. Fertilizer and water management

In addition to applying sufficient base fertilizer during planting, fertilizer should be applied in the later stage, especially in the early stage, in order to make pear trees grow rapidly, nitrogen fertilizer is often applied to promote the growth of pear trees. Compound fertilizer should be applied from post-anthesis to flower bud differentiation to supplement the nutrition needed for plant growth, while in the fruit expansion stage, potash fertilizer and a small amount of phosphate fertilizer should be applied to make the fruit expand rapidly. Pear trees have strong tolerance to drought. Generally, they can be watered once after topdressing in no place.

3. Pruning and pollination

In order to make the plant grow strongly, blossom and bear fruit more, and increase the yield, it is necessary to prune and trim when the seedlings grow to 70 or 80 centimeters, pruning buds to promote branches and accelerate crown formation. When the shape of the tree has been formed, it is necessary to trim off erect, overdense branches, long branches, disease and insect branches, ineffective branches, and leave more auxiliary branches. In addition, in order to ensure the fruit yield, in addition to increasing fertilizer at the flowering stage, artificial pollination should be carried out to ensure high yield.

4. Pest control

Diseases and insect pests are also one of the reasons that affect the yield of pear trees. The main diseases of pear trees are powdery mildew, ring disease and rust, which mainly harm the leaves and fruits of the plant, so that the plant can not grow and develop normally, the number of flowering and fruiting is small, and in serious cases, it leads to plant death and the end of harvest. The method of prevention and control is agricultural control combined with chemical control, disinfection of tree seedlings and soil before planting, and water spraying control. The main pests of pear trees are aphids, pear planthoppers, pear heart borer and pear stem wasps, etc., sucking the branches and leaves of young parts or eating plant parts, affecting plant growth and yield, also combined with the two methods of prevention and control, remove weeds and debris around the plant before overwintering, reduce insect sources, and spray with insecticides when the disease occurs.

The above are the high-yield pear planting techniques brought by the pro-agricultural network. I hope it can be helpful to you. Pay attention to the pro-agricultural network and learn more about it.
