New high (pear)

I. Source of varieties

Beijing Forestry Bureau introduced it from Korea in 1999 and planted it in Beijing Huangqi nursery. Parent combination: Yinhe × this village autumn. It was approved by Beijing in 2002.

2. Characteristic characteristics

This variety was selected from Japan and belongs to sand pear system and large fruit type pear. After it was introduced from Korea, the open-heart cultivation technique of grid was adopted.

The tree is strong and half-open. Easy to form short fruit branches and axillary flower buds, 7-9 flowers per inflorescence. The leaf is broadly oval, the leaf margin is serrated, the leaf is dark green, and the back of the leaf is tomentose. Annual branches are yellowish brown, lenticels are large and dense, and branches are stout.

The fruit is flat and round, with small and dense spots. The average fruit weight is 450,500g, the maximum is 1000 grams, the soluble solids content of the fruit is 15%, the peel is thin, the pulp is milky white, the stone cells are few, the fruit juice is more, and the edible rate is 92%. The peel has a dark brown background and turns light brownish yellow after bagging. In Huangqi nursery, the flowering period is in the middle of April, and the fruit ripening period is in late September, about 15 days earlier than that in South Korea.

This variety needs to be planted with pollination trees, and Huashan pear and Qiuhuang pear are suitable. High yield, stable yield, high quality, strong resistance to scab and black spot, if too much fruit is easy to cause premature senescence, fruit thinning should be strengthened, irrigation and drainage should be done during cultivation.

The young trees began to blossom in the second year and bear fruit in the third year. The average yield per mu in Beijing was controlled at 2000-2500 kg to ensure fruit quality.

The fruit should be refrigerated after harvest.

III. Key points of cultivation techniques

The main results are as follows: 1. the plant growth potential is strong, pay attention to reasonable close planting, 45 plants per mu.

2. It is suitable to configure pollination trees with abundant water, autumn yellow, Ganquan and Yuanhuang pear.

3. In the first year of planting, apply sufficient base fertilizer to ensure adequate supply of fertilizer and water in the first two years, and promote the formation of tree crown as soon as possible. After the result, the management of fertilizer and water should be strengthened, especially the amount of organic fertilizer should reach 5-10 cubic meters per mu.

4. Pull branches in time to improve ventilation and light transmission conditions.

5. The high grafted tree can pull branches and strengthen the tree in time in the first year, and the flower bud can be formed in the second year.

6. nitrogen fertilizer should be added in time after fruit harvest, and foliar fertilizer spraying and root application should be combined. 7. fruit must be bagged, and attention should be paid to the control of Tenebrio Molitor, Pear planthopper, etc.

Pest in bag.

IV. Areas suitable for planting

It is suitable for planting in Beijing area.
