Problems solved by technology

At present, Nanjing Tilia's propagation technology is mainly based on seed propagation and cutting propagation. However, the low yield of Nanjing Tilia seeds, low seed plumpness, and deep dormancy characteristics seriously affect the reproduction of Nanjing Tilia. There are also related researches on twig cuttings, but it still leads to The survival rate of Nanjing Tilia is not high, and the late fruiting rate is low

Embodiment 1

[0020] A kind of Nanjing linden root transplanting seedling raising method, comprises the following steps:

[0021] 1) Picking roots: Picking roots in autumn and winter, using the seedling roots pulled out during or after seedling raising, selecting robust middle-aged trees 0.5m away from the main trunk to dig out the roots and ears of Nanjing Linden, and soaking the dug out roots and ears with water for 2 hours ; The ambient temperature for picking the roots is 0°C, and the time for picking the roots is 8:00 in the morning;

[0022] 2) root fringe making: trim the root fringe with scissors, the length is 25cm, the thickness of the big head is 1.5cm, the upper end is flat and the lower end is oblique, which are respectively the upper and lower ends of the root fringe, and it is 95% ethanol for 2min to elute with mass percent concentration, and then use Rinse thoroughly with water;

[0023] 3) Hormone treatment: Step 2) Dip the lower ends of the treated roots and spikes with 5...

Abstract

The invention discloses a tilia miqueliana root cutting seedling growing method. Tilia miqueliana root cuttings are adopted for root cutting seedling growing, cottonseed hulls are used as seedling growing matrix, and the matrix is loosened and nutrient-rich and can promote germination of the tilia miqueliana rapidly. Through adopting electromagnetization water, penetration and dissolving capacity of the water can be reinforced. Through applying organic boron fertilizer in the matrix, rotten roots are controlled, sufficient fertilizer and excellent growing environment are provided, and growth and budding of the root cuttings are further promoted by plant growth hormone gibberellins. Roots of seedlings obtained by the seedling growing method are prevented from being injured when transplanted, survival rates of the seedlings are high, the tilia miqueliana can be planted in all seasons without being limited by climate, the seedlings of the tilia miqueliana come out evenly, and survival rate of afforestation is high.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a Nanjing linden root cutting seedling raising method. Background technique [0002] Nanjing Tilia is a deciduous tree belonging to Tiliaceae, up to 15 meters high; young branches and young stellate hairs; leaves triangular-ovate, 4-11 cm long, 3.5-9 cm wide, short and acuminate at the top, obliquely centered at the base Shaped or truncate, with short sharp serrations on the edge; the surface is dark green, nearly glabrous, with gray stellate hairs on the back; the petiole is 2 to 4 cm long, hairy when young, and nearly glabrous later. The cymes are 7-9 cm long, and the rachis of the inflorescence has stellate hairs; the bracts are long spatulate, with stellate hairs on the surface vein axils, and densely star-shaped hairs on the back; the inflorescence has 10-20 flowers; the sepals are about 4 mm long, and the outer Stellate hairs, villous inside; petals g...
