The method designs a tree form as a base 3-7 branches, and selects Acer buergerianum single plants with a rice diameter of more than 7cm and harmonious tree postures to form branches of clustered Acer buergerianum; excavating planting holes, placing the acer truncatum in the designed tree shape, washing soil balls adjacent to root systems with a screwdriver or water to remove the soil and leave the roots, enabling the adjacent single plant root systems to be close to each other, and treating the root systems with a compound preparation with the root promoting and sterilizing effects; fully backfilling loam mixed with organic fertilizer, compacting, and fully irrigating; surrounding sandy soil around the tree pit; building a plurality of independent triangular supports and fixing each individual plant to form branches of the clustered maples; watering and fertilizing in time, and culturing for 2 years.

Description

Rapid cultivation method for easily transplanted clustered acer truncatum

Technical Field

The invention relates to the technical field of directional cultivation of nursery stocks, in particular to a rapid cultivation method for easily transplanted clump maples.

Background

The acer truncatum is a deciduous tree of Acer, has red or yellow autumn leaves, is a native tree species with wide natural distribution in China, and has strong adaptability, barren resistance and strong root germination capacity. Cultivating into single trunk, and planting in park or making street tree; is also suitable to be made into bonsai and is popular with people.

The existing amount of the Chinese deltoid maple in the nursery is large, while the existing amount of the Chinese deltoid maple is small, and the Chinese deltoid maple is favored by the market due to the unique shape. The acer truncatum is one of the important shapes of acer truncatum, and the base of the acer truncatum can be designed to have 3 to 7 branches. In recent years, the seedlings and cooperative farmers of our company are favored by clients for the differentiation development of the clustered acer truncatum.

The cultivation period of the clustered acer truncatum formed by natural branches is more than 10 years, so that the greening engineering requirements can be met, the current nursery stock is few, and the current market landscape construction requirements cannot be met.

Disclosure of Invention

The invention aims to solve the technical problems that the tufted triangle maple is deficient, the cultivation period of the tufted triangle maple growing naturally is long, the shape is difficult to meet the current market demand and the like, and the defects of the existing tufted triangle maple cultivation technology are overcome, a novel method for quickly cultivating the tufted triangle maple with a specific shape is provided, and the tufted triangle maple cultivated through key steps of tufted triangle maple shape design, single plant optimization, combined planting, preparation treatment, loam backfilling, surrounding sandy soil, support frame building, tracking management and protection and the like has the characteristics of short cultivation period, tree shape designability, high survival rate, easiness in transplanting and the like.

The invention aims to overcome the defects of long cultivation period and the like of the existing acer truncatum, and provides a method for quickly cultivating the clump acer truncatum of the required tree form, which is characterized by comprising the following steps:

(1) according to market demands, tree forms are designed flexibly, and the triangular maple forms are usually designed to be 3-11 branches of a base.

(2) Selecting healthy Acer buergerianum (Maxim.) harms with diameter of more than 7cm and harmonious tree posture, and pruning to coordinate tree posture.

(3) The soil ball surfaces which are close to each other are removed by a screwdriver to leave roots, the root systems of the individual plants are mutually cross-linked, and the exposed root systems and the soil ball surfaces are treated by a compound preparation with the formula of '70% thiophanate methyl 800 times liquid + 100-200 mg/LNAA + 100-200 mg/L IAA'.

(4) Drawing a circle 75cm around the center of the clustered maple, slotting gaps, filling 1-2 cm of sandy soil, and facilitating transplanting when sold after 2 years.

The method can effectively make up the defects of the production technology of the clustered acer truncatum, cultivates the acer truncatum modeling nursery stocks which are urgently needed in the market by designing the clustered tree-shaped structure, can promote the healing and regeneration of the root system wounds of the acer truncatum through the treatment of the composite preparation, improves the landscape value of the acer truncatum, and can meet the requirements of the current landscape construction.

The method is convenient to operate, the clustered acer truncatum can be designed and cultivated according to market demands, the formula of the compound preparation is simple, and the root is treated by using a spraying method. With the differentiated development of landscape construction, the application of the clustered acer truncatum is more and more extensive, and the clustered acer truncatum has wide market prospect on the premise of ensuring the healthy growth and attractive appearance of the clustered acer truncatum.

The specific implementation mode is as follows:

the present invention is further illustrated by the following specific examples.

Example, a rapid cultivation method for easily transplanting acer truncatum. Designing the number and the shape of the branches of the clustered acer truncatum according to market demands, and designing the acer truncatum into a 3-branch natural obliquely upward growing form; selecting 3 Acer buergerianum single plants with slightly curved tree postures, coordination with each other and 8 cm-diameter, removing inner branches and overlapped branches, and pruning to form a fasciculate tree shape with attractive structural layout; excavating a planting hole with the diameter of 140 cm; lifting seedlings, removing soil balls and roots of crossed roots, crossing partial single-plant roots, and planting the single-plant roots in a designed tree form combination; treating the bare root with a compound preparation of '70% thiophanate methyl 800 times liquid +100mg/LNAA +200mg/L IAA'; uniformly mixing 7kg of organic fertilizer into loam in each hole, fully backfilling tree holes, and compacting; digging annular ditches around the tree pits, filling 1-2 cm of sandy soil, and taking soil balls when the trees are transplanted out of the nursery after 2 years in size and depth; building a plurality of independent triangular supports, and fixing each individual plant to form 3 branches of the clustered acer truncatum; watering in time for 4-8 months, and additionally applying 350g of urea every month; and (5) applying organic fertilizer once every 7kg per cluster for 12 months, and watering in time. In autumn and winter, 7kg of organic fertilizer is applied to each cluster, and the fertilizer can be sold after tracking and protecting for 2 years.

The 3 kinds and concentrations of the compound preparation selected in the embodiment are more effective formulas selected after a plurality of medicament tests and concentration blending, so that the survival rate of the acer buergerianum with the diameter of more than 7cm can be improved, the acer buergerianum can grow healthily, and the cultivation of the clustered acer buergerianum is guaranteed; annular ditches are dug around the tree pits, and 1-2 cm of sandy soil is filled, so that soil balls can be formed after 2 years of sale.
