Embodiment 1

[0038] A method for quickly cultivating large-scale original crown seedlings of purple maple, the main steps of which include: cultivating large-scale rootstock original crown seedlings, transplanting the original crown rootstock seedlings, grafting full crowns, and post-management.

[0039] (1) Cultivate the original crown seedlings of large-scale rootstock: Acer three gorges is used as the grafted rootstock variety of Acer purple fruit. The sowing time is from late February to early March. Before sowing, the seeds need to undergo 40 days of low-temperature stratification and germination treatment, and the sowing rate is 2.0-2.5kg / mu. After sowing, the seedlings will be transplanted twice and finally cultivated into large-scale original crown rootstock seedlings. The sowing time is from late November to early March of the following year. The specific method is: when the sown seedlings are cultivated to d2-3cm, carry out the first Transplanting, the row-to-plant spacing of tra...

Embodiment 2

[0064] A method for rapidly cultivating large-scale purple maple original crown seedlings, comprising:

[0065] (1) Sowing and cultivating rootstock seedlings: full-tillage soil preparation is used for bed sowing, and impurities must be cleaned before soil preparation, and then the finely divided soil is deeply plowed by machinery, and 4-5 tons of decomposed organic fertilizer is applied to the sowing land per mu. Sowing is carried out from late February to early March every year. The seeds have to undergo 40 days of low-temperature stratification and germination treatment. The sowing method is ditch drill with a distance of 15-20cm and a seeding rate of 2.0-2.5kg / mu.

[0066] (2) Cultivate middle seedlings on rootstocks: select d2-3cm, height > 1.5m annual strong young seedlings to carry out bare-root transplanting. Before transplanting, the root system of bare-root seedlings should be properly pruned, and the site should be prepared for transplanting. The planting row spacing...

Abstract

The invention provides a rapid cultivation method for large-size Acer cordatum Pax original crown seedlings. The method mainly comprises the following steps: 1, cultivating large-size stock original crown seedlings: taking treated Acer wilsonii seeds as stock sowing materials, and transplanting twice to cultivate large-size original crown seedlings; 2, transplanting original crown rootstock seedlings: before grafting, selecting large-sized original crown tree-shaped seedlings as rootstocks, and transplanting according to a shallow planting and high cultivating mode after pruning and wound treatment measures are taken; 3, full-crown grafting: carrying out full-crown staggered grafting on each reserved branch by adopting a grafting method; 4, final-period management: timely removing bags andbinding films, trimming, preventing and treating plant diseases and insect pests, supporting, preventing sunburn and performing other measures in the later period to improve the survival rate and theyield. Aiming at the blank and defects of large-sized Acer cordatum Pax original crown seedling cultivation, the invention provides the large-sized Acer cordatum Pax original crown seedling rapid cultivation method which is simple to operate and can realize large-scale production.

Description

technical field [0001] The invention relates to the technical field of forestry, and further relates to seedling cultivation technology, in particular to a rapid cultivation method for large-scale purple maple original crown seedlings. Background technique [0002] Purple fruit maple is a deciduous tree belonging to Acer family Aceraceae. It has the characteristics of beautiful tree shape, strange fruit shape and changeable leaf color. [0003] The seedlings of purple maple grow slowly, and most of the large-scale purple maple seedlings used for landscaping are wild resources or high-grafting grafted seedlings. For high-end grafting, the three-gorge maple or green maple with a ground diameter of d = 3-7cm is used as the rootstock. When grafting, the grafting is carried out on the spot at a place about 1m above the ground. It usually takes 5 years from grafting to qualified seedlings emerging from the nursery. Above, the tree shape is mostly cluster seedlings with multiple m...
