Tilia americana cuttage technology capable of air purification

Abstract

The invention discloses a Tilia americana cuttage technology capable of air purification, wherein detailed instructions are given to material section, architecture of a cuttage bed, selection of a cuttage medium and management after cuttage. The method has the advantages that the rooting rate reaches 33%-60%; the curing starting period is increased by 4-6 days; the cut curing period is increased by 7-10 days; and the rooting period is increased by 6-12 days.

Description

technical field [0001] The invention relates to an air-purifying linden cutting technology. Background technique [0002] American forged leaves are large, oval or elliptical, 20cm long, 15cm wide, the tip of the leaf is cone-shaped, the edge of the leaf is serrated, the surface is wrinkled, dark green, the back is smooth, except for the brown tufts in the leaf axil, the rest is glabrous , petiole glabrous, 2.5-3cm long. The flowers are light yellow, with a crown width of 1.5cm, usually with five petals, fragrant in midsummer, 10 drooping clusters, each cluster surrounded by a bract about 10cm long. The bracts are oblong or broadly lanceolate, 3.5-7cm long, glabrous; fruit spherical, densely covered with brown hairs, 0.5-1cm in diameter, bark brown or dark gray, with long cracks and scale-like folds on the surface. [0003] The main ecological factors of Tilia americana, such as climate and soil, are very similar to the excellent native tree species of Tilia americana, whi...

Problems solved by technology

However, the data show that the stamens ripen first, self-flowering is almost sterile, cross-pollination, the seed-setting rate is also low, generally not more than 10%, and the fruiting has obvious periodicity, and most of the fruits have no developed seeds.
