Problems solved by technology

However, the crown of Luotian weeping fir is narrow and small, the growth of branches is weak and the number is small, not only the collection is difficult and the quantity is limited, but also the growth potential of the materials for grafting or cutting propagation is weak, the partial crown is obvious, and the germination ability is poor, which is not suitable for construction. Ear picking nursery or direct cultivation of seedlings

Embodiment 1

[0037] Embodiment 1: Cultivation of shoots at the base of the isolated wood of Luotian weeping fir

[0038] (1) Selection of the mother tree: Select the 22-year-old Luotian weeping fir isolated tree. The mother tree is required to have obvious morphological characteristics, prominent growth advantages, robustness and no pests and diseases, and sufficient light transmittance should be ensured around;

[0039] (2) Mother tree management:

[0040] ① Ventilation and light transmission: timely cut down 2m around the mother tree 2 ~4m 2 Miscellaneous shrubs or small forest trees within the range, to ensure the ventilation and light transmission at the base of the mother tree;

[0041] ② loose soil and remove impurities: every winter or after collecting spikes, put 1m in the root plate of the mother tree 2 ~2m 2 Loose soil and weeding within the range, the depth of loose soil is 15cm-20cm, combined with loose soil to remove miscellaneous irrigation and its root system;

[0042] ...

Embodiment 2

[0055] Example 2: Cultivation of basal shoots of Luotian weeping fir budding forest excellent trees

[0056] (1) Selection of mother tree: Select excellent trees in the 18-year-old Luotian weeping fir bud forest. The mother tree is required to have obvious morphological characteristics, prominent growth advantages, robustness and no pests and diseases, and sufficient light transmittance should be ensured around;

[0057] (2) Mother tree management:

[0058] ① Ventilation and light transmission: timely cut down 2m around the mother tree 2 ~4m 2 Miscellaneous shrubs or small forest trees within the range, to ensure the ventilation and light transmission at the base of the mother tree;

[0059] ② loose soil and remove impurities: every winter or after collecting spikes, put 1m in the root plate of the mother tree 2 ~2m 2 Loose soil and weeding within the range, the depth of loose soil is 15cm-20cm, combined with loose soil to remove miscellaneous irrigation and its root syste...

Embodiment 3

[0073] Embodiment 3: Cutting seedlings of the base sprouts of Luotian weeping fir

[0074] ①Treatment of spikes: a. Ear making: Select spikes without side branches, semi-lignified to lignified, with whorls of needles, thickness ≥ 0.3cm, trim the cuttings with 6cm to 10cm in length and terminal buds, cut at the base of the cuttings Smooth, no broken skin, no splitting; b. Disinfection; c. Hormone treatment;

[0075] ② Substrate configuration: Peat soil and perlite are configured in a volume ratio of 6:4, slightly acidic. Spray disinfection with 0.3% to 0.5% potassium permanganate solution 5d to 7d before cutting.

[0076] ③ Cutting container: light mesh bag container bag or plug tray, the specifications are diameter or caliber ≥ 4.5cm, length or depth 12cm ~ 15cm. The container bag is placed in a tray with the same aperture, and the tray or hole tray can be placed on the seedling raising rack.

[0077] ④Spray facilities: all-optical automatic spray equipment.

[0078] ⑤ Cut...

Abstract

The invention discloses a cultivating method for basal coppice shoots of cunninghamia laceolata and a cutting seedling method. The cultivating method is characterized in that excellent single plants of isolated trees, sparse forests or sprout forests of the 8-25-year cunninghamia laceolata are selected; preconditions of not cutting down forest and preserving existing resources are obeyed; no cutting orchard needs to be newly built, coppice shoots are cultivated by adopting a method for promoting sprouting of basal parts, and the key problem of cutting seedling of the cunninghamia laceolata is solved in a targeted manner. The obtained cutting seedlings are relatively thick and strong, and have developed root systems and high afforestation survival rate; nursery stocks in the same year of afforestation grow quickly, so that the afforestation cost can be reduced and the afforestation quality is improved; meanwhile, the cultivating method and the cutting seedling method disclosed by the invention have the advantages of simple technology, easiness in operation, land conservation, less material consumption, high yield and low cost; the breeding period can be shortened by 5 years or longer; the cultivating method and the cutting seedling method are quite suitable for being popularized and used in production.

Description

technical field [0001] The invention belongs to the technical field of Chinese fir vegetative propagation, and in particular relates to a method for cultivating basal sprouts of Luotian weeping branch fir and cutting and raising seedlings. Background technique [0002] Chinese fir (Cunninghamia lanceolata (Lamb.) Hook.) is an important high-quality coniferous timber tree species with the most widely cultivated, fast-growing and high economic value in the Yangtze River Basin and south of the Qinling Mountains. Fir wood is yellowish-white, sometimes with light reddish-brown heartwood, soft, delicate, fragrant, straight texture, easy to process, strong corrosion resistance, used for construction, bridges, shipbuilding, ore pillars, stakes, poles, furniture and Wood fiber industry raw materials, etc. Hubei has rich hydrothermal conditions and is one of the most suitable cultivation areas for Chinese fir. At present, the planting area of ​​fir is expanding continuously, and the...
