Embodiment Construction

[0011] The seed germination treatment method of a kind of North American red oak in the present embodiment comprises the following steps: collect seeds in early October, soak the seeds in water at 5-15°C for 24-36 hours, then add wet sand into the bag after mixing the substrate, and wet the seeds in the bag. The humidity of the sand is maintained at 80-90%, stacked and stacked, and covered with 2-3 layers of plastic film for wintering, the mass ratio of the substrate mixed with seeds and wet sand is 1:2-3; the plastic film is gradually lifted in the spring of the next year Ventilate and permeate the water, then take out the seeds, wash and place them in a warm water shaker at 25-30 degrees Celsius for 3-5 hours, then take them out and put them in a hotbed for cultivation. The humidity of the wet sand in the hotbed is 75-85%. Seeds covered with sand 3~5cm. The temperature is maintained at 25-30 degrees Celsius, and germination usually begins on the third day, and lasts for a we...

Abstract

The invention discloses a seed germination method for Quercus rubra, and belongs to the field of plant breeding. The method comprises the following steps: collecting seeds in the first ten-day period of October, soaking the seeds with 5-15 DEG C water for 24 to 36 hours, mixing with a substrate, adding wet sand, putting into a bag, stacking, and covering 2 to 3 layers of plastic films for overwintering, wherein the mass ratio of the substrate mixed in the seeds to the wet sand is 1:(2-3); and gradually opening the plastic films for ventilation and water permeation in spring of the next year, taking the seeds out, cleaning, oscillating the cleaned seeds in a 25-30 DEG C warm water shaker by stages for 3 to 5 hours altogether, taking the seeds out, and culturing in a hotbed at the temperature of between 25 and 30 DEG C. By the method, the bud ratio is greatly improved through seed breeding, high quality seedlings can be bred effectively by using germplasm resources; and according to the method, the bud ratio is up to 85 percent.

Description

technical field [0001] The invention relates to the field of seedling propagation, in particular to a method for cutting red-leaf plums in autumn and winter. Background technique [0002] North American red oak (Quercus rubra), Fagaceae Quercus. Native to the eastern United States and southeastern Canada, it is now distributed in Asia, Africa and America. It is a valuable fast-growing garden tree species and a very beautiful street tree. The tree is tall and the trunk is straight. The crown is round to conical, the leaves are wavy, the leaves are 7-11 lobed, 11.5-21.3cm long, 10-15cm wide, dark green, shiny, alternate. The new leaves are chestnut red, the summer leaves are green and shiny, the autumn leaves are red, the petiole is 2.5-5.0cm long, and the autumn leaf color gradually changes to pink, bright red or reddish brown. Intolerant to salt and alkali, like sandy loam or well-drained slightly acidic soil, cold-resistant, not wind-resistant. In recent years, my count...
