Embodiment 1

[0031]Choose 0.5 mu of sandy loam on the newly opened land from east to west, turn the ground, prepare the ground, and rake the ground in the first winter, build a 2m high greenhouse, open the compartment at 1.5m, apply 70kg of compound fertilizer as the base fertilizer when the compartment surface is flat, and the compartment surface is fine, 2 Planted on 22nd. Wash the seeds with newly drawn well water to remove the deflated seeds. Before planting, soak the seeds of glabra tree with 100ppm gibberellin + 500 times carbendazim + 1000 times thiophanate-methyl solution at 25°C for 13 hours, drain the water, mix with river sand with 10 times the amount of seeds, and mix the river sand with the seeds Put it into the blender and grind it for 40min.

[0032] Spread 5cm thick new mix soil on the car surface (new land reclamation soil: 1:2 sieved river sand), level it, sow 7kg evenly, cover the new mix soil 2cm, use a sprayer to spray the car surface with a fine mist, and use a spray...

[0035] Choose 0.5 mu of sandy loam on the newly opened land from east to west, turn the ground, prepare the ground, and rake the ground in the first winter, build a 2m high greenhouse, open the compartment at 1.5m, and apply 100kg of compound fertilizer as the base fertilizer when the compartment surface is flat, and the compartment surface is fine, 2 Planted on the 27th. Wash the seeds with newly drawn well water to remove the deflated seeds. Before planting, soak the seeds of glabra tree with 100ppm gibberellin + 500 times carbendazim + 1000 times thiophanate-methyl solution at 26°C for 15 hours, drain the water, mix in plant ash with 10 times the amount of seeds, river sand and seeds and mix evenly Then put it into the blender and grind for 40min.

[0036] Spread 5cm thick river sand with a thickness of 10-20 mesh on the car surface, level it, sow 6kg evenly, cover the river sand with 2cm, use a sprayer to spray the car surface with fine mist, and build a 30cm high small a...

Abstract

The invention provides a direct seeding seedling cultivation method of Cornus wilsoniana. The direct seeding seedling cultivation method of Cornus wilsoniana comprises the steps of nursery land selection requirements, seeding time, seed treatment, greenhouse erection, seeding density, management before seedling emergence, early management after seedling emergence, middle-period and final-period management after seedling emergence, transplantation after seedling emergence and the like. According to the method, the land selection requirements for the seedling cultivation of Cornus wilsoniana arestandardized; land selection, land utilization and soil treatment are conducted according to the regulations, so that the infection rate of the seedlings is extremely low, the transplantation survival rate of the seedlings reaches 90% or above, the seedling cultivation density is large, the seedling production quantity per unit area is large, and benefits are significant. Two types of scientificnutrition formulas are adopted, rational nutritive proportion is provided for various growth stages of the seedlings, various nutrient elements needed by the growth of the seedlings are ensured, the use efficiency of a greenhouse is improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to a large-scale seedling raising method using glabra seeds, and belongs to the technical field of economic forest cultivation. Background technique [0002] The light bark tree is an ideal multi-purpose oil tree species. The bark is white with greenish patches, forming obvious markings after peeling off in patches. Leaves opposite, elliptic to ovate-elliptic, base cuneate, back densely covered with papillae and flat gray-white pubescence. Cymes terminal. Flowers small, white. Drupe spherical, purple-black. The flowering period is May, and the fruiting period is October-November. The drupe is spherical and purple-black. Natural distribution The light bark tree is widely distributed in the south of the Yellow River, concentrated in the limestone areas from the Yangtze River Basin to the southwest, and vertically distributed below 1000 meters above sea level. [0003] Light bark likes light, is cold-resistant, likes deep, fert...
