Problems solved by technology

[0003] Traditional beech propagation is mainly based on seed sowing and seedling cultivation. Because beech seeds are small, seedlings need to be sown on fertile sandy loam soil with convenient drainage and irrigation. The best time for sowing is spring. Starting from the characteristics, scientific cultivation and management are not carried out every time the beech seeds grow, resulting in only 30-50% germination rate of beech seeds, and the germination rate is low, and the beech seedlings that survived after seedling cultivation are even more less, lower output, not suitable for factory expansion; in terms of the current emphasis on greening projects, the cultivation time of zelkova, quality demand, etc. can not be ignored, and will bring more benefits to the industry of planting zelkova Great economic benefits, which requires higher beech cultivation technology
[0004] In order to shorten the entire growth cycle of beech seedling cultivation, and growers can quickly cultivate high-quality and strong seedlings, the most common cultivation method today has a low germination rate and poor quality seedlings, and the cultivation of seedlings by cuttings and grafting is complicated. It is difficult for growers to master, it is uneconomical, and it is not conducive to large-scale promotion. Therefore, how to cultivate high-quality seedlings is the most critical issue in the entire beech cultivation technology.

Embodiment 1

[0028] (1) Seed harvesting: from October to November of each year, select good-quality zelkova mother trees from 20-50 years of adult forest stands with strong growth, good dryness, and disease-free pests as the objects for collection of zelkova seeds. , The seeds are harvested by cutting the fruit branches, and harvesting when the zelkova fruit turns from green to yellowish brown;

[0029] (2) Seed treatment and storage: the surface of the harvested zelkova seeds are treated with impurities, and then they are laid flat in an indoor ventilated place to dry naturally for 2 days, and then air-selected. The moisture content of the zelkova seeds is controlled at 0 ~13%, then put the treated zelkova seeds into a cloth bag and hang them in a ventilated and dry place indoors for storage;

[0030] (3) Selection of nursery land: choose farmland with convenient transportation, sufficient water source, power supply in place, flat terrain, sunny leeward and convenient drainage as nursery land,...

Embodiment 2

[0039] The difference from the first embodiment is:

[0040] (3) The selection of nursery land: The nursery land needs loose, deep, light loam with good drainage;

[0041] (4) The whole planting and pretreatment of the nursery: 1800kg of decomposed pig and cow dung, 200kg of decomposed vegetable cake, 50kg of superphosphate, and the width of the seedling bed is 1.2m and the height is 28cm.

[0042] (5) Pre-treatment of seeds before sowing: Dry the seeds at 6°C for 9 days, and set aside;

[0043] (6) Seed sowing: The sowing time is in late February each year, the sowing amount is 8kg per mu, the spacing between sowing rows is 30cm, the ditch width is 10cm, and it is covered with loam with a thickness of 0.5cm;

[0044] (7) Seed and bud management: the height of the scaffold is 2.1m;

[0045] (8) Seedling management: The intertillage weeding and weeding are sprayed with 40ml of high-efficiency fluroxypyr per mu with a concentration of 10.8% and 35kg of water. The thinning of the seedling s...

Embodiment 3

[0047] The difference from the first embodiment is:

[0048] (1) Seed harvesting: The seed harvesting adopts the method of natural shedding collection;

[0049] (2) Seed treatment and storage: The seeds are laid flat in a ventilated place and dried naturally for 3 days;

[0050] (3) Selection of nursery land: select old nursery land with convenient transportation, sufficient water source, power supply in place, flat terrain, sunny leeward and convenient drainage as nursery land;

[0051] (4) Planting and pretreatment of nursery land: plowing the old nursery land in time after seedlings, planting beds in early spring, do not repeat cropping, and applying 2000kg of decomposed pig and cow dung per mu of nursery land and decomposed vegetable cakes during plowing and preparation 220kg, superphosphate 60kg, seedbed width 1.5m, height 30cm;

[0052] (5) Pretreatment of seeds before sowing: the seeds are soaked in warm water for 3 days, and finally the seeds are dried at 8°C for 8 days for use...

Abstract

The invention discloses a method for cultivating high-quality beech seedlings, which belongs to the technical field of plant cultivation. The method comprises the following steps: (1) harvesting of seeds; (2) processing and storage of seeds; (3) selection of nursery grounds (4) Nursery cropping and pretreatment; (5) Seed pretreatment before sowing; (6) Seed sowing; (7) Seed bud stage management; (8) Seedling stage management; (9) Disease and insect pest control; (10) Seedlings out of the nursery and management; the cultivation method of the high-quality beech seedlings of the present invention is a scientific, systematic, comprehensive and easy-to-implement cultivation method, from the collection of seeds to the nursery stock after the nursery stock is formed and the management is done in detail. The operation method shows that the germination rate of the seeds is high, the survival rate is high, the growth of the cultivated seedlings is good, neat, high-quality and robust, suitable for high-yield afforestation, and high economic benefits.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, in particular to a method for cultivating high-quality beech seedlings. Background technique [0002] Beech (also known as blood beech, golden palm, sand palm, beech, etc.), also known as big-leaf beech, is an arbor tree species of the genus Beech in the family Ulmaceae, and is a national second-class key protected plant. It is widely distributed in China, grows slowly, and has excellent materials. It is a precious hard-leaved broad-leaved tree species and an excellent tree species for viewing autumn leaves. It is often planted on roadsides and walls in green spaces for solitary planting, cluster planting and street trees. . Beech has strong adaptability, strong wind resistance, and resistance to smoke and dust. It is a good tree species for urban and rural greening and building windbreak forests. [0003] Traditional beech propagation is mainly based on seed sowing and seedling culti...
