Last Updated: 2024/11/25, First, improved seed breeding 1. Seed selection: the suitable time for seed collection is from late November to mid-December in North China, and the trees with strong strength, good posture and strong resistance are selected as the mother trees. In the afternoon on a sunny day, select seeds with high maturity, full seeds, disease-free and insect-free seeds, and dry them in a cool and ventilated place to avoid sun exposure. two。 Soil preparation: select 2 parts of fertile sandy loam with pH 6.7 to 7.0, 1 part of high quality peat soil, 1 part of field soil, and then add 1.5 kg of diammonium phosphate per cubic soil.

I. breeding of improved varieties

1. Seed selection: the suitable time for seed collection is from late November to mid-December in North China, and the trees with strong strength, good posture and strong resistance are selected as the mother trees. In the afternoon on a sunny day, select seeds with high maturity, full seeds, disease-free and insect-free seeds, and dry them in a cool and ventilated place to avoid sun exposure.

two。 Soil preparation: select 2 parts of fertile sandy loam with pH 6.7 to 7.0, 1 part of high quality peat soil, 1 part of field soil, and then add 1.5 kg of diammonium phosphate and 2 to 3 kg of superphosphate per cubic soil. Sowing substrate can also be used to evenly spread 1 to 3 cm thick. The soil preparation can meet the technical requirements of upper sand and lower viscous slightly acidic soil, which lays a good foundation for root growth and cultivation of strong seedlings at seedling stage.

3. Sowing and post-seedling management: the direct harvest of dry seeds according to 15 to 20 kg / mu strip sowing, the greenhouse can be carried out in December. It is generally appropriate for the ground temperature to rise to 14 ℃ to 16 ℃ in the middle of March. The emergence of seedlings is higher when sowing in the open field. It is important to maintain humidity from sowing to seedling emergence, so that you can see wet but not dry. Three months after seedling, organic fertilizer and compound fertilizer were applied in furrow to coordinate the proportion of nutrients, so as to achieve the goal of strong seedling and straight branch.
