Problems solved by technology

Long cypress often adopts the method of cutting in early winter to grow seedlings. With the existing technical means, the survival rate of cuttings is only about 85%, and when large-scale seedlings are raised, the cuttings need to be stored in sand, which prolongs the cycle of seedlings.

Embodiment 1

[0016] A method for raising seedlings by cuttings of Cypress in winter, comprising the following steps:

[0017] (1) In mid-November every year, select three-year-old branches of four-year-old trees as cuttings, and the length of the cuttings is 11cm;

[0018] (2) Tie 50 cuttings into a bundle, and then put them into the soaking solution for 12 hours, wherein the soaking solution is made of the following components by weight: 12 parts of Toosendan, 14 parts of Magnolia officinalis, 14 parts of Gansong 8 parts of black trigonum, 10 parts of iron wire grass, 0.2 parts of thiamine nitrate, 4 parts of vetiver oil, 150 parts of water;

[0019] (3) After the soaked cuttings are treated with ultrasonic waves for 15-20 minutes, then irradiate the cuttings with purple light for 20 minutes;

[0020] (4) Untie the cuttings irradiated by purple light for cutting. Before inserting the cuttings into the seedling-raising matrix, soak the base of the cuttings in the rooting solution for 10 s...

[0024] A method for raising seedlings by cuttings of Cypress in winter, comprising the following steps:

[0025] (1) In mid-November every year, select 3-year-old branches of 4-year-old trees as cuttings, and the length of the cuttings is 13cm;

[0026] (2) Bind 60 cuttings into a bundle, and then soak them in the soaking liquid for 13 hours, wherein the soaking liquid is made of the following components by weight: 13 parts of Toosendan, 15 parts of Magnolia officinalis, 16 parts of Gansong 9 parts of black trigonum, 12 parts of iron wire grass, 0.3 parts of thiamine nitrate, 5 parts of vetiver oil, 160 parts of water;

[0027] (3) The soaked cuttings were treated with ultrasonic waves for 17 minutes, and then irradiated with purple light for 25 minutes;

[0028] (4) Untie the cuttings irradiated by purple light for cutting. Before inserting the cuttings into the seedling-raising matrix, soak the base of the cuttings in the rooting solution for 11 seconds, and then cut the cu...

Embodiment 3

[0032] A method for raising seedlings by cuttings of Cypress in winter, comprising the following steps:

[0033] (1) In mid-November every year, select three-year-old branches of four-year-old trees as cuttings, and the length of the cuttings is 14cm;

[0034] (2) Bind 70 cuttings into a bundle, and then soak them in the soaking liquid for 14 hours, wherein the soaking liquid is made of the following components by weight: 15 parts of Toosendan, 16 parts of Magnolia officinalis, 17 parts of Gansong 11 parts of black trigonum, 13 parts of ironwort, 0.5 parts of thiamine nitrate, 6 parts of vetiver oil, 170 parts of water;

[0035] (3) After the soaked cuttings are treated with ultrasonic waves for 15-20 minutes, then irradiate the cuttings with purple light for 30 minutes;

[0036] (4) Untie the cuttings irradiated with purple light for cuttings. Before inserting the cuttings into the seedling-raising matrix, soak the base of the cuttings in the rooting solution for 12 seconds,...

Abstract

The invention provides a winter cutting seedling culture method for sabina chinensis. The method comprises the steps of: (1) in the middle ten-day period of November every year, selecting triennial branches with a tree age of four years as cutting slips, wherein the length of the cutting slips is 11-14cm; (2) binding 50-70 cutting slips into a bale and putting the cutting slips into a soaking liquid for soaking the cutting slips for 12-14h; (3) treating the soaked cutting slips with ultrasonic waves for 15-20min and then illuminating the cutting slips with purple light for 20-30m; (4) unbinding the cutting slips treated with purple light illumination and performing cuttage, placing roots of the cutting slips into a rooting medium for soaking the roots for 10-12s before the cutting slips are inserted in a seedling culture medium, and then performing cuttage. The winter cutting seedling culture method for sabina chinensis solves the problem of low survival rate of winter cutting seedling culture in the prior art, saves sand storage for cutting slips in large-scale seedling culture, shortens a seedling culture cycle and greatly promotes the development of the sabina chinensis planting industry.

Description

technical field [0001] The invention belongs to the field of agricultural planting, and in particular relates to a method for raising seedlings of cypress in winter by cuttings. Background technique [0002] Long cypress, also known as juniper, red heart cypress, pearl cypress, etc., is a cultivated variety of juniper. Long cypress grows to a certain height, and its branches spiral upwards, like a coiled dragon, so it is named "long cypress". Cupressaceae Juniper tree, 21 meters high, 3.5 meters in diameter at breast height; bark dark gray, longitudinally split, and cracked in pieces; young trees usually extend obliquely, forming a steeple-shaped crown, and old ones. The lower branches are flat, forming The crown is broad and round, the bark is gray-brown, split longitudinally, and breaks into irregular sheets and falls off; the branchlets are usually straight or slightly curved, and the branchlets with scales are nearly cylindrical or nearly quadrangular. Commonly used in ...
