Cultivation method for improving survival rate of quercus rubra

Abstract

The invention discloses a cultivation method for improving the survival rate of quercus rubra. The cultivation method comprises the following steps: S1, collecting seeds, namely collecting mature seeds of quercus rubra during October to November in autumns, and screening out plump seeds; S2, pretreating the seeds, namely soaking the screened seeds in hot water at 50-60 DEG C for 40-50 minutes, picking out the seeds, washing the seed surfaces with clear water, drying the seeds in the air, uniformly spraying the seeds with a 0.2% potassium permanganate solution, performing disinfection, and soaking the seeds in a seed soaking solution for 12 hours; S3, putting the seeds in a hot bed; S4, taking out the seeds; S5, sowing the seeds, namely sowing the seeds in a greenhouse; and S6, performing tending management. According to the method, dormancy of the quercus rubra seeds is broken, the seeds can be directly sown and germinate without long-time cold-wet treatment, the seeds are promoted togerminate early, the germination rate of the seeds is improved, the growth cycle of nursery stocks can be prolonged, the survival rate of tree seedlings in the late period can be greatly improved. Therefore, the method can improve the survival rate of quercus rubra.

Description

technical field [0001] The invention belongs to the technical field of tree cultivation, and in particular relates to a cultivation method for improving the survival of the North American red oak. Background technique [0002] The North American red oak tree is tall, with a well-proportioned crown, dense branches and leaves, beautiful leaf shape, colorful colors, and a long red leaf period. The leaves still persist on the branches in autumn and winter, and the ornamental effect is good. It is mostly used for landscape tree planting; it is also an excellent street tree and garden Shade trees are widely planted in lawns, parks, golf courses and other places. It has strong resistance to urban pollution, strong material, dense and beautiful texture. It is a good fine wood and can be used to make valuable furniture. It is especially suitable for large-scale cultivation and is widely used in urban greening. It also has ecological value and can be used for land restoration. [00...

Problems solved by technology

[0004] The purpose of the present invention is to provide the cultivation method that improves the survival of North American red oak, to solve the above-mentioned background technology, propose the North American red oak conventional sowing and seedling raising method is to directly sow the seeds in the soil, because of the red oak seed has dormancy characteristics, it needs to be in 3 Normal germination can only be achieved after being treated under cold and wet conditions for about a month. There are many pathogenic bacteria and underground pests in the soil, and factors such as poor soil aeration lead to extremely low germination rates in the fields where seeds are sown in the soil. Traditional seedling raising methods give The problem of large economic losses caused by the production of forest tree seedlings
