Embodiment 1

[0044] Embodiment 1, the hydroponic rooting method of the black pine needle bundle adopts the following steps:

[0045] 1. Hydroponic facilities: Use tissue culture racks to make hydroponic racks. The hydroponic racks can be divided into multiple layers and are illuminated by LED lights; the hydroponic site is indoors;

[0046] 2. Hydroponic carrier: Use a plastic tray as the hydroponic box, and a foam board with a thickness of 1.35cm as the carrier of the needle bundle. The foam board is cut into small pieces of no more than 15×15cm;

[0047] 3. Acquisition of coniferous bundles: From January to February every year, cut fully developed 1-year-old branches from 2 to 4-year-old black pine clones, and collect coniferous bundles with dark green color and strong growth as test materials; during collection, Use the thumb and index finger of your right hand to pinch the base of the needle-leaf bundle, first twist it left and right, and then pull it along the growth direction of the ...

Embodiment 2

[0059] Embodiment 2, the black pine needle bundle hydroponic rooting method, comprises the steps:

[0060] 1. Hydroponic facilities: Use tissue culture racks to make hydroponic racks. The hydroponic racks can be divided into multiple layers and are illuminated by LED lights; the hydroponic site is indoors;

[0061] 2. Hydroponic carrier: Use a plastic tray as the hydroponic box, and a 1.2cm thick foam board as the needle bundle carrier, and cut the foam board into small pieces not exceeding 15×15cm;

[0062] 3. Collection of coniferous bundles: from January to February every year, from 2 to 4 days hybrid F 1 On the generation seedlings, cut fully developed 1-year-old branches, and collect coniferous bundles with dark green color and strong growth as test materials; when collecting, pinch the base of the coniferous bundles with the thumb and forefinger of your right hand, and twist them left and right first. Then pull along the growth direction of the needle-leaf bundle to rem...

Embodiment 3

[0072] Embodiment 3, black red pine needle leaf bunch hydroponic rooting method, comprises the steps:

[0073] 1. Hydroponic facilities: Use tissue culture racks to make hydroponic racks. The hydroponic racks can be divided into multiple layers and are illuminated by LED lights; the hydroponic site is indoors;

[0074] 2. Hydroponic carrier: use a plastic tray as the hydroponic box, and a 1.5cm thick foam board as the needle bundle carrier, and cut the foam board into small pieces not exceeding 15×15cm;

[0075]3. Acquisition of coniferous bundles: From January to February every year, from 2 to 4 d-old black pine clones, cut fully developed 1-d-old branches, and collect coniferous bundles with dark green color and strong growth as test materials; during collection, Use the thumb and index finger of your right hand to pinch the base of the needle-leaf bundle, first twist it left and right, and then pull it along the growth direction of the needle-leaf bundle to remove the needl...

Abstract

The invention discloses a water culture rooting method of needle-leaved bundles of Pinus thunbergii and P.densiflora hybrid. The method is characterized by comprising steps as follows: preparation of water culture facilities and water culture carriers, collection of the needle-leaved bundles, storage of the needle-leaved bundles in sand, preparation of a nutrient solution, hormone treatment, penetration and fixation of the needle-leaved bundles, temperature and humidity control and the like. According to the method, the utilization rate and the efficacy of the needle-leaved bundles are remarkably increased, the water culture carriers are changed, and the suspension problem of the needle-leaved bundles is solved; the yellowing problem caused by malnutrition of the needle-leaved bundles is solved due to improvement of the matching ratio of a modifier to the nutrient solution; requirements for the water culture field are not strict, the temperature and the humidity are better controlled, and the rooting time is remarkably shortened.

Description

Technical field: [0001] The invention relates to the subject of seedling cultivation in the field of forestry science and technology (code 2202220), in particular to a hydroponic rooting method of black pine needle bundles; it is used for asexual reproduction of seedlings of pine species such as black pine and red pine. Background technique: [0002] Red pine is an important afforestation pioneer tree species, and one of the main constructing species of temperate coniferous forests in warm temperate coastal areas. Black pine has been introduced for hundreds of years. It has been widely used due to its resistance to the damage of pine caterpillars and pine scales. It is a dominant tree species for the construction of northern coastal shelterbelts. [0003] Black pine is an excellent variety bred with black pine as the female parent and red pine as the male parent. It has the characteristics of fast growth, strong stress resistance and large genetic gain. Its 7a tall growth e...
