The crown is pyramidal, wide, sometimes spherical. It reaches 5 m in width. The leaves are oblong, ciliary-serrate. The bark is dark brown. There are growths in the form of thorns.

Fruit Description

From beautiful and large flowers, fruits are formed. They grow in a bunch and have a short stalk. The description of the fruits of the Ussuri pear is as follows:

  • round in shape, slightly elongated;
  • small weight - up to 100 g;
  • length up to 6 cm;

Care

For high yield pear tree need to ensure timely care.

Landing

The sowing period of the seeds of the Ussuri Pear is autumn. Before sowing, the seeds of the Ussuri Pear stratify:

  • for stratification, the seeds are placed in wet sand;
  • a container with them is placed in a refrigerator with a temperature of 0-5 ° C;
  • seeds are kept in the refrigerator for 2-4 months.

The most favorable time for planting a seedling is spring or autumn. You can use 1-2 year old seedlings.

It is important that the soil has good drainage. A mixture of turf land, peat and sand is suitable.

The tree needs good care

Dig a hole exactly to the size of the root system of the seedling. Fertilizers and humus are placed in it. You can use a mixture of wood ash with lime in a ratio of 1: 1.5. Another option is to mix manure or humus (60 kg), superphosphate (1.5 kg), potassium chloride (0.7 kg.)

A mound is poured into the middle of the pit and a landing stake is set. The stake is driven deep enough into the ground: by 0.5-1 m. Its lower side is treated with antifungal fluid.

At the end, the tree is covered with earth, rammed and fixed with the help of a landing stake. The pear planted is watched for several weeks until it takes root in a new place.

Watering

The Ussuri pear is drought-resistant. The lack of watering affects the condition of the fruit and fruiting.

When watering adhere to the following rules:

  • Watering is required when planting and over the next 3-4 days.
  • The main watering occurs in spring and autumn. Watering is also necessary in particularly hot weather in the summer. Especially young seedlings need watering.
  • The volume of water is 2-3 buckets under each tree. Volume may increase, depending on the weather and condition of the tree.
  • The best way to water is sprinkling. Water should fall under the tree in drops for 2-3 weeks.
  • To better retain water, a 10-15 cm ditch is dug around the trunk.

Good watering increases the yield of the pear and accelerates its growth. During filling, additional, but moderate, moisture positively affects the taste of the pear.

Mulching and cold protection

The Ussuri pear can withstand severe frosts, but mulching will eliminate any risks.

Protection Rules:

  • Mulching is best done with organic materials. As such material use grass, foliage, humus.
  • Mulching is carried out during planting and in the fall.
  • To protect against snow, the lower part of the trunk is additionally wrapped. To do this, use agrofiber, burlap or cane.
  • The bottom of the trunk is sprinkled with earth at 1-15 cm. In spring, this land is removed and dug up.

Mulch is also used as protection against weeds, but you need to monitor its condition so that it does not become a carrier of diseases.

Pruning

Pruning of branches is carried out in the second year after planting. The pruning period is spring, when it is still cold enough.

Trimming is carried out to form a crown. In the process, thin out and shorten the branches. Cut the main conductor and side branches to the first kidneys. To enhance air exchange inside the crown, it is thinned out. Cut off excess branches. Pruning is also carried out in order to clean the tree and prevent disease. Sick, dry and broken branches are removed.

Correctly formed crown provides convenience when leaving and picking fruit.

Top dressing

Even such an unpretentious culture as the Ussuri pear needs additional nutrition. Frequency of fertilizer application:

  • Each year, the soil is fertilized with nitrogen. Nitrogen fertilizers are applied before flowering.
  • Once every 2-3 years, 5 kg of manure is introduced. Manure is replaced with peat or humus.
  • Once every 3-4 years, potash and phosphate fertilizers are added. 500 g of potassium chloride and 500 g of superphosphate interfere with 20 kg of humus.

Due to the large amount of lime in the ground, the roots begin to deteriorate. For prevention, a solution of lime is applied to the soil six months before planting.

Diseases and Pests

Some pests and diseases are able to withstand winter cold, therefore, if pests are detected, the soil is treated with a solution of colloidal sulfur.

Rust is transmitted through juniper. To prevent this disease, they monitor the plants that are next to the tree. Against a tartar, the tree is sprayed with a solution of kalbofos, kemifos or nitrafen.

Conclusion

The Ussuri pear is one of the best for growing in the northern regions. Proper care of it provides excellent productivity and a pleasant taste of the fruit.
