Description

A kind of cultivation method of magnolia

technical field

The invention relates to arboriculture technology, in particular to a cultivation method of magnolia.

Background technique

Magnolia, Magnoliaceae, a deciduous tree, up to 25 meters in diameter, 200cm in diameter, light-loving, slightly shade-tolerant, relatively cold-resistant. It likes deep, fertile, moist, and well-drained neutral to slightly acidic soil. The tree is vigorous and strong, full of flowers, and it looks white and flawless from a distance. It is very enchanting. It is one of the excellent plant varieties in garden plant landscaping. Seed seedling transplanting method is mostly used in artificial cultivation planting, but because its characteristic of Magnolia magnolia is not resistant to transplantation, there are certain problems in the transplanting process and planting management process, resulting in low transplanting survival rate, poor tree growth, Yellow leaves and other phenomena have affected its ornamental value to a certain extent.

Contents of the invention

Purpose of the invention: In order to solve the problems of low survival rate and poor growth of transplanted trees existing in the prior art, the present invention proposes a new cultivation method of magnolia that improves survival rate and tree growth quality.

Technical scheme: for reaching above purpose, the present invention adopts following technical scheme: a kind of cultivation method of Magnolia, comprises the steps:

(1) Seedling selection and excavation: Water the seedling field once 3-5 days before the excavation of the seedlings, select seedlings with no disease, regular tree shape, straight trunk, and no damage. Wrap up and tie up;

(2) Planting land treatment: choose a planting land that is sheltered from the wind, has light, and has a flat and open terrain, plows 25-40cm deep, and evenly sprinkles 20-30kg of ferrous sulfate per mu, covering the soil; after 3-5 days, the row spacing of plants is 2m× Dig a tree hole at 2m. The diameter of the tree hole should be 30-50cm larger than the diameter of the soil ball, and 20-40cm deeper than the height of the soil ball. Pave a 10-20cm thick gravel tile at the bottom of the hole, and then lay a layer of 10-15cm straw;

(3) Transplantation: Before transplanting, apply 8-10kg of decomposed organic fertilizer in each tree hole, plant the seedlings with soil balls excavated in step (1) into the tree hole, and mix 15-20% into the backfill soil Sandy soil, compacted, watered immediately after planting, watered for the second time after 3 days, and watered for the third time after 5 days;

(4) Fertilizer and water management: Fertilize three times a year. For the first time, apply nitrogen, phosphorus and potassium compound fertilizer 30-50kg/mu before flowering. For the second time, apply phosphorus and potassium compound fertilizer 30-50kg/mu in July to August. Apply 60-80 kg/mu of decomposed organic fertilizer before winter; during the cultivation process, watering management is based on keeping the soil moist without water; weeding frequently to prevent pests and diseases.

In order to protect the root of the plant from damage, the diameter of the soil ball in the step (1) is 7-10 times the diameter of the plant.

Furthermore, in order to ensure the air permeability of the plant root system during transportation, the soil balls in the step (1) are wrapped with air-permeable fiber mesh and hemp rope.

Beneficial effect: a kind of cultivation method of Magnolia provided by the present invention proposes in detail a complete set of cultivation methods from seedling selection, excavation, planting site pretreatment, seedling transplantation method to later fertilizer and water management, effectively avoiding the seedling transplanting process The root system is damaged to varying degrees, which affects the survival rate. The pretreatment of gravel and sandy soil in the planting site ensures the aeration of the planting soil, and the management of fertilizer and water in different periods in the later period also ensures that the fertilizer efficiency of the magnolia tree is sufficient during the growth process. , improve the survival rate of magnolia trees, ensure the quality of tree growth and flowering, and enhance the disease resistance of plants.

Detailed ways

Example 1:

A cultivation method of magnolia, comprising the steps of:
