Embodiment Construction

[0015] The present invention will be further described below in conjunction with specific embodiments.

[0016] A kind of Quercus nata seedling root control container seedling raising method, selects the large seedling of Quercus nata, prunes branches and root systems, removes weak branches and diseased branches when pruning branches, removes old roots and exposes new stubble when pruning roots, and controls the root length at 15-18cm, so as to ensure the survival rate after transplanting; soak the root system with rooting powder and 800 times dilute carbendazim solution, and then transplant the bare root into a root control container filled with cultivation medium, and soak the root system After transplanting, it can promote rapid rooting after transplanting, and disinfect and sterilize the root system to prevent the occurrence of pests and diseases. The root control container used in the present invention is a commercially available root control container.

Abstract

The invention relates to the technical field of propagation methods of quercus nuttallii, in particular to a quercus nuttallii large seedling root control container seedling growing method. The method includes the following steps that quercus nuttallii large seedlings are selected, branches and root systems are pruned, weak branches and ill branches are removed when the branches are pruned, old roots are removed when the root systems are pruned, new stubbles are exposed, and the root length is controlled between 15 cm to 18 cm, the root systems are soaked in rooting powder and an 800-fold carbendazim dilute solution, the naked roots are transplanted into a root control container filled with culture media, a frame is built for supporting and fixing, and water, fertilizer and pest and disease damage after transplantation are managed. The quercus nuttallii large seedling root control container seedling growing method has the advantages that root control container seedling growing has the features of being high in transplantation survival rate, good in transplantation effect and the like, however traditional seedling cultivation does not have the features; the side roots can be thick and short in shape with the root control container, and wound spiral roots will not be formed; the defects of root wining caused by seedling growing with a conventional container are overcome, and the total root amount is increased. By means of the method, the seeding survival rate can be at least 95 percent, the seedling growing period is shortened by a half, and the seedling quality is high.

Description

technical field [0001] The invention relates to the technical field of propagation methods of Quercus natae, in particular to a method for raising seedlings of Quercus natae in a root-controlled container. Background technique [0002] The Yangtze River Delta plain area including southern Jiangsu is an area with abundant wetlands and high groundwater table, and there are few suitable ecological landscape tree species. The water-resistant wet oaks produced in North America are the preferred tree species for the construction of human habitat environment forests, water conservation forests, timber forests, and animal and bird habitat forests in the Yangtze River Delta region. These new varieties of water-resistant and wet ecological landscape seedlings are still in the development stage and have a large market capacity. [0003] Quercus nigra is a tree species of the Fagaceae Quercus, native to the southeastern United States, mainly distributed in the subtropical coastal plains...
