What is the price of pear saplings? How to plant high yield?

Pear tree is one of the main fruit trees in China, in addition to raw food, it can also process canned pear wine, dried pear, preserved pear and so on. So what is the price of pear saplings? How to plant high yield?

What is the price of pear seedlings?

The price of pear seedlings is not very high, generally between 2-5 yuan per plant, which is specifically affected by the varieties of pear trees and the specifications of seedlings.

The standard of high quality pear seedlings:

1. Purity: purity is required to reach more than 98%.

two。 The trunk of Class A seedlings is more than 100-150 cm high, and there are more than 6-8 robust buds within 70-100 cm of plastic band, with a diameter of more than 0.8-1.0 cm, the trunk is perfect and the branches are mature. The underground part should have more than 5 sturdy lateral roots with a length of more than 15-20 cm (the measured root thickness is more than 0.3cm, the branches are strong, the distribution is uniform, there are more fibrous roots, the graft interface heals well, and there is no serious mechanical injury. )

3. No big and small foot disease, no root cancer, no root nodule aphid, root woolly aphid and other diseases and insect pests.

4. We can not choose the continuous cropping seedlings in the seedling plots for more than two years, let alone the seedlings in which 920 is used or smeared with growth hormone such as "Liba" in the seedling raising process.

5. The survival rate, disease resistance, high yield and stable yield of more than 5 lateral roots cultured by root-cutting method are higher than those of single-root seedlings, so it is the best choice to buy pear seedlings.

Second, how to plant pear trees with high yield?

1. Establishment of pear orchard

Garden selection and planning can develop pear orchards regardless of flat land, hills, mountains and river beaches, but transportation, irrigation and other conditions should be considered. After the orchard address is selected, the orchard should be divided into several communities according to 2-10 hectares according to topography, topography, roads, channels and shelterbelts. In the hilly sloping land, the long side of the district is parallel to the contour as far as possible, which is beneficial to soil and water conservation and easy to manage. Pear trees can be planted from defoliation to pre-germination, and the planting density is determined according to different topography and land plots. Generally, the row spacing is 3m × 4m.

two。 Planting technology

Dig holes according to the distance between plants and rows, generally sandy soil, with a width of 80cm and a depth of 50-60cm, and rice holes with a width of 80cm and a depth of 40-50cm. First, add 30-40cm thick straw, branches or green manure, and add topsoil to tighten, then apply organic fertilizer (pig, cow manure) 50-80kg or pure chicken manure 10kg to mature, and add calcium magnesium phosphate fertilizer 1-2kg (alkaline soil can be used calcium superphosphate) mixed with soil to make steamed bread. Before planting, it is necessary to cut off 2-3cm from the thick roots of pear seedlings to promote the occurrence of new roots and remove the film at the grafting site so as not to affect the growth of the trunk. When planting, the grafting interface should be exposed to the ground 5-10cm, firm rhizosphere soil, immediately irrigate enough water. Tuyere zone, need to set up a pillar to prevent lodging.

3. Soil, fertilizer and water management technology

(1) soil management

Deep ploughing and ripening of soil is a basic measure in the technology of increasing yield of pear trees. The time of deep ploughing and soil improvement is generally carried out after fruit harvest in autumn and before defoliation in winter. The methods include hole expansion, deep ploughing of the whole garden, interrow or interplant deep ploughing. The depth of deep turning is generally 30-40cm, and it can be turned every other year where possible, with a deep trench of about 0.8m in width on both sides of the original hole in 1, 3 and 5 years, and on the other side in 2, 4 and 6 years, combined with the application of base fertilizer. Generally, 100kg pear fruit needs at least organic fertilizer (pig, sheep stable manure) 100kg, and then mixed with 2.25kg phosphate fertilizer.

(2) Fertilizer management

In addition to base fertilizer, in general, topdressing should be applied four times during the growing period, and the first post-anthesis fertilizer should be applied in mid-late April to promote branch and leaf growth, flower bud differentiation and fruit expansion, with a profit of 8-10 kg per mu; the second fruit expansion fertilizer should be applied twice from mid-May to early June, with a profit of 15-20 kg per mu. The third postharvest fertilizer was applied from late August to mid-September. Jiamei earned 10-15 kg per mu to increase leaf color, prolong leaf life and restore tree potential.

In addition, combined with spraying Jiamei platinum for 2-3 times, extra-root topdressing can restore the nutrition level of the tree in time, and the effect is very obvious. In general, the amount of fertilizer applied to pear trees in the full fruit period should not be lower than the standard of jin fruit fertilizer. The set fertilizer is balanced according to the ratio of nitrogen: phosphorus: potassium 1: 0.5-0.7: 0.8-1.0, mainly Jiamei Yinglai and Nei potassium Germany.
