Embodiment Construction

[0021] The present invention is described in detail below in conjunction with specific embodiment:

[0022] The specific operation steps of the method of the present invention can be as follows:

[0023] 1. Selection of rootstock seeds and germination with wet sand

[0024] After harvesting the Quercus japonica fruit, put it in a ventilated room for 3-4 days, let it ripen and dry in the shade, use a coarse sieve with a diameter of 1.0-1.5cm to screen large, plump and pest-free seeds, and the one with a diameter of 1.5cm is the best. Soak in 0.5% potassium permanganate solution for half an hour for disinfection, then rinse with clean water, and store them in layers with river sand and seeds, specifically: put 10cm of sand on a flat floor, and sprinkle the above seeds evenly on it, Avoid overlapping the seeds as much as possible, cover with river sand with a thickness of 3 cm, and pour thoroughly with clean water. Generally, spray water every 10-15 days, preferably every 13 da...

Abstract

The invention discloses a quercus acutissima seedling rootstock cultivation method. The quercus acutissima seedling rootstock cultivation method comprises the following steps: (1) screening large-grain and full seeds without diseases and insect pests and immersing and disinfecting the seeds with a potassium permanganate solution; then rinsing the seeds with clean water to be clean; (2) sowing the seeds on river sand and covering the seeds with river sand having the thickness of 3cm; performing thorough watering with clean water to enable the humidity of the river sand to be about 60%, the temperature of the river sand to be 20 DEG C to 25 DEG C before March 20 and the temperature before grafting to be 25 DEG C to 30 DEG C in the middle ten days of April; and (3) continuously stacking the sand for covering germinated quercus acutissima seedling rootstocks after the beginning of April so as to enable quercus acutissima seedling rootstock germination time to be matched with lignification time of quercus acutissima current-year branches. The invention further discloses a quercus acutissima seedling culture method.

Description

technical field [0001] The invention relates to a method for planting oak oak, in particular to a method for cultivating oak seedlings and a method for raising seedlings of oak. Background technique [0002] Oak is one of the preferred tree species for biomass energy in my country's "Twelfth Five-Year Plan", but the natural yield is not high, and artificial planting needs to be vigorously developed. However, the artificial planting of Oak Quercus is difficult. The most important thing is that a feasible method for raising seedlings has not been found, and the survival rate is not high. [0003] Finding a convenient, fast and effective breeding method for Quercus queris has always been a difficult problem for our forestry scientific and technological workers. There are two main methods of propagation of Quercus variegata: (1) Field seedling cultivation and container bag cultivation of Quercus variegata seedlings. The deficiency of this method mainly is: the progeny that the...
