Detailed Explanation of Key Points on Pear Seedling Selection and Planting Techniques

Selection of pear seedlings: The best ones have a plant height above one meter, stem thickness above 0.8 cm, plump buds, a well-developed root system, no pests or diseases, and no shrunken bark. Seedlings with wrinkled stem bark are mainly caused by being lifted too early and poor moisture retention, and such seedlings are unfavorable for root development after planting.

Regarding pear seedling planting techniques, to improve the survival rate of pear seedlings, the following points should be followed when planting pear seedlings:

1. Match pollinator trees well. When planting pear seedlings, pollinator trees need to be planted, and the planting ratio of pollinator trees to main cultivar trees is 1:4-6, preferably planted between rows.

2. Reasonable planting density. Early-maturing varieties are planted at about 83 trees per mu (spacing 2 x 4 m), and mid-to-late-maturing varieties at about 42-56 trees per mu (spacing 4 x 4 m-4 x 3 m).

3. Dig holes before planting. Holes should be dug about 50-60 cm deep, with 50-60 kg of fully decomposed organic fertilizer applied per tree, and the planting soil should be about 15 cm above the bed surface.

4. Clean the seedling roots. Before planting, properly trim the seedling root system by 3-4 cm to promote root development. When planting, the graft union should be exposed above the ground, firm the soil around the roots, and apply diluted human manure to promote seedling survival and root development. To prevent root diseases, a 50% carbendazim 600-fold solution can be used to water the roots, with about 150 ml poured per tree.
