Method for commercialized cultivation of container seedling of cold-resistant japanese cinnamon germplasm

Abstract

The invention relates to a method for commercialized cultivation of container seedling of cold-resistant japanese cinnamon germplasm. During the process of culturing seedlings, the requirements for the technical links such as seed harvesting, storing, matrix sterilizing and the like are strict; according to the features of different stages of container seedling cultivation, the method of the invention adopts the technical scheme of rational base fertilizer, foliage dressing, water treatment, pruning and so on; and the configuration materials of the matrix are easily-accessible, and are low in cost, and the seedlings have good growth adaptability and grow fast. According to the growth characteristics of japanese cinnamon, the method of the invention divides the container seedling cultivating into two stages so as to effectively avoid the possible damages to the seedlings caused by low temperature in winter and effectively increase the growth speed of the seedlings. The method of the invention uses the technical indicators of seedling age, shape, physiology and so on as the basis, determines the quality grade of seedlings of different usages, reduces the application cost of afforestation and greening, and improves the application effects.

Description

Technical field [0001] The invention relates to a container seedling cultivation method, in particular to a method for cultivating Tianzhugui germplasm container seedlings. Background technique [0002] Cinnamomum japonicum Sieb.var.chekiangense (Nakai) MPTang et Yao is a subtropical evergreen small and medium tree of the genus Cinnamomum in the Lauraceae family. It has developed main roots and deep roots. It has growth characteristics such as light-loving, water-resistant and fast-growing, and it likes good drainage. Slightly acidic soil. It is mainly produced in Zhejiang, Anhui, Jiangxi, Fujian, Taiwan and other provinces south of the Yangtze River. It is mostly born in evergreen broad-leaved forests below 1000m above sea level. The stem shape of Tianzhu Osmanthus is straight, the tree posture is beautiful, the tree shape is tall and beautiful, it is evergreen in all seasons and has a strong fragrance. It also has the characteristics of anti-smoke and less pests and diseases. ...

Problems solved by technology

[0004] However, there are still some defects and deficiencies in the above-mentioned research results. For the seedling propagation technology in horticulture and forestry technology, the seedling raising method is a systematic whole. The specific management methods in cultivation and cultivation have interrelated characteristics, which directly affect the survival rate of seedlings, and further affect the growth rate and quality of seedlings

For example, although the studies of Yu Ciying, Du Peijian, etc. mentioned container seedling cultivation, and also gave the optimal plan of the substrate, they did not provide a complete method for container seedling cultivation of Tianzhugui, such as open field sowing, cutting propagation, etc. Both are quite different from container seedling raising methods, and are only a general concept, which has little reference value for the whole set of seedling raising schemes; although Xu Binfen, Du Peijian and others have given some assumptions about
