When do paulownia trees blossom and lose their leaves?

1. Paulownia trees usually bloom from March to April, and the flowering period lasts about one month. 3-5 paulownia flowers form small Cymes with total pedicels or none, but most of them form large inflorescences due to the shedding of winter leaf-like involucre and bracts. The lateral branches of inflorescence branches vary in length, making the inflorescences paniculate, pyramidal or cylindrical. Corolla large, purple or white, funnel-shaped bell-shaped to tubular funnel-shaped, there are two longitudinal pleats in the abdomen (only white paulownia has no obvious longitudinal pleats), there are often dark purple spots on the inside, yellow at the longitudinal fold uplift.

2. the bark of young trees is smooth but the lenticels are obvious, the big trees gradually split longitudinally, the leaf branches are sparse, and the crown is conical or umbrella-shaped. Most tree species belong to pseudo two-branched branch terminal buds wither after overwintering. Leaves opposite, large and long stalked, leaf area gradually decreases with age, inflorescences Cymes paniculate, flowers stipitate, calyx fleshy, obconical or bell-shaped, Corolla large, purple or white. Fruit a capsule, ovate or ellipsoid, seeds elliptic, very small, numerous.

How to plant paulownia trees?

1. Choose improved varieties: the so-called paulownia is actually the general name of the genus Paulownia. There are 9 species in this genus, and the species suitable for growing in the south are paulownia paulownia or a hybrid with paulownia as its parent. Six paulownia clones selected by Fuzhou Forestry Science Research Institute of Jiangxi Province have rapid growth, straight stem shape, high trunk under branches and strong adaptability, so they are suitable to be popularized in the south of the Yangtze River.

two。 Root-burying seedling: the nursery land with leeward to the sun, sandy loam or loam soil can be selected to make a high ridge seedling bed with a height of 15cm and 20cm high, and the roots of 1-year-old and 2-year-old seedlings should be directly buried roots. the row spacing of buried roots is 1 m × 0.8 m or 1 m × 1 m, apply sufficient basal fertilizer, and apply quick-acting chemical fertilizer during the peak growth period from June to August to promote its rapid growth.

3. Afforestation: afforestation on the four sides requires digging large holes and applying sufficient base fertilizer, and mountain afforestation requires banded terrace soil preparation, the thickness of loose soil layer is 50-70 cm, and sufficient base fertilizer is applied to achieve the purpose of rapid growth in the same year of afforestation. The planting density of forest is 5 m × 5 m, planting 26 trees per 667 square meters (1 mu), planting 13 trees per 667 square meters with both forest and grain, and planting 6 trees per hectare with 4 m × 30 m.
