Embodiment Construction
[0049] A method for promoting early fruiting of pear saplings, the steps are:
[0050] 1. Cultivate strong pear sprouts:
[0051] 1.1 Cultivation of rootstock seedlings:
[0052] 1.1.1 Rootstock variety selection and seed stratification:
[0053] Choose rootstock varieties with strong stress resistance suitable for planting in this area: such as Du pear or Dou pear, and select the fresh and plump seeds of the year for sand storage stratification. Stratification begins in mid-to-late December in Wuhan. Stratification conditions: clean river sand, the water holding capacity of river sand is kept at 50%; storage environment: temperature 2 or 4 or 5 or 6 or 7 ℃, ventilated; stratification time: 40 or 43 or 45 or 48 or 50 days, 50% of the seeds start powder mouth. The seeds treated by stratification germinate neatly, have a high emergence rate and grow vigorously.
[0054] 1.1.2 Soil preparation and sowing:
[0055] Choose a place that is leeward to the sun and close to the wa...

Abstract
The invention discloses a method for facilitating early fruiting of a young pear tree. The method comprises the following steps of: A, cultivating strong pear seedlings, namely selecting stock, laminating seeds, preparing lands, seeding, managing stock seedlings, grafting the stock seedlings and the like; B, planting the pear seedlings, namely selecting the pear seedlings, performing high-ridge plantation, managing soil, fertilizers and water of the pear seedlings, preventing and controlling insects and diseases and managing branches and tips; and C, flowering the young pear tree, namely bending the branches, carving, removing the tips, pinching and the like. By the method, the early fruiting of a newly-planted young pear tree can be facilitated, and the fruiting period can be 2 years earlier. The strong pear seedlings are cultivated and planted; and due to improvement on fertilization, irrigation and pruning technologies, the vegetative growth of the pear tree is controlled, the reproductive growth is facilitated, and the aim of fruiting the young pear tree early is fulfilled.
Description
technical field [0001] The invention belongs to the field of fruit tree research, and more specifically relates to a method for promoting early fruiting of pear saplings, which can effectively solve the problems of late fruiting and long childhood of pear saplings in scientific research, breeding and production of pears. This method is suitable for scientific research units, companies and individuals engaged in pear scientific research, breeding and production. Background technique [0002] Pear belongs to Rosaceae (Rosaceae) Apple subfamily (Maloideae) Pyrus (Pyrus) plant, is the deciduous fruit tree of Qiaoben, is one of three major cultivated fruit trees in my country, and also occupies a pivotal position in the world. According to the China Yearbook statistics, in 2009 my country's pear planting area was 10.743 million hectares, with an output of 1.426 million tons, ranking first in the world. Pear production has always been an important pillar industry for Chinese farm...
