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 method for cultivating colored ornamental coniferous ear-picking mother plants with steam and mist. Background technique [0002] Colored ornamental coniferous trees mainly refer to the evergreen color-leaved tree species introduced from abroad in recent years, which are dominated by Cupressaceae. Because of their evergreen seasons, diverse colors, and strong resistance, they perform well in northern my country and have become northern gardens. The new darling of plants for greening and landscaping has high promotion and application value. However, due to the high price of imported seedlings, it is economically unreasonable to buy in large quantities, and a small amount of ear-picking mother plants are introduced and cultivated in a conventional manner, and because of their slow growth, it is difficult to produce more cuttings in a short period of time. The sho...

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
