Air cultivation method of stock plants of colored ornamental coniferous trees

Abstract

Disclosed is an air cultivation method of stock plants of colored ornamental coniferous trees. The method comprises the steps of establishing an air cultivation bed provided with a spraying and controlling system in a greenhouse; determining spacing in the rows and spacing between rows of the plants according to growth rates of tree seeds and planed cutting ages; planting the stock plants to be cultivated on the air cultivation bed and enabling root systems to be suspended in the air cultivation bed; directly carrying out interval spraying on the root systems with nutrient solution after the stock plants are planted; and carrying out root cutting back trimming once in March every year according to growing situations of root systems of different tree seeds and the principle of cutting more for plants which grow fast and cutting less for plants which grow slowly, and adjusting the stock plants according to the ratio of root length to crown height to promote growth of parts above the ground. According to the air cultivation method of the stock plants of the colored ornamental coniferous trees, aerial root systems of the colored ornamental coniferous trees are enabled to be stronger than ordinary earth culture terrestrial root systems of the colored ornamental coniferous trees in length and superficial area, metabolic activity is strong, nutrition absorption efficiency is high, nursery-grown plants grow fast, and the fast expanding propagation purpose can be achieved.

Description

technical field [0001] The invention relates to the technical field of garden plant cultivation, in particular to a steam mist cultivation method for colored ornamental conifers with ear picking mother plants. Background technique [0002] Colored ornamental conifers mainly refer to the evergreen color-leaved tree species introduced from abroad in recent years, mainly in the cypress family. Because of their evergreen four seasons, various colors, and strong resistance, they perform well in northern my country and have become northern gardens. It is a new favorite plant for greening and landscaping, which has high promotion and application value. However, due to the high price of imported seedlings, it is economically unreasonable to purchase large quantities of seedlings, while a small number of mother plants for ear picking are introduced and cultivated in a conventional way, and due to their slow growth, it is difficult to produce many cuttings in a short time. The shortag...

Problems solved by technology

The existing conventional technology is exactly to plant the seedlings introduced in the field or greenhouse as the mother plant for picking ears, and promote its growth under the situation of strengthening fertilizer and water management. Generally about 20, the mother plant grows slowly and has a low reproductive coefficient
