Potted sowing and seedling raising method capable of increasing emergence rate of pinus thunbergii

Abstract

The invention belongs to the technical field of pinus thunbergii planting and particularly relates to a potted sowing and seedling raising method capable of increasing emergence rate of pinus thunbergii. The specific method comprises steps as follows: (1) pinus thunbergii seeds are soaked in a disodium hydrogen phosphate water solution for thermal insulation and soaking, the seeds are drained, fished out and soaked in ailanthus juice, the seeds are drained, fished out and magnetized, and to-be-sown pinus thunbergii seeds are obtained; (2) the to-be-sown pinus thunbergii seeds are sown in potted nutrient soil, and one seed is sown in each pot at the sowing depth of 1.7-1.9 cm; the potted nutrient soil is prepared from raw materials as follows: grape skin residues, leaf mould, fresh bamboo sap, activated medical stone powder, gallic acid, curcumin, isorhynchophylline and buckwheat hull; rapid germination and seedling emergence of the pinus thunbergii seeds are promoted, the seedling emergence rate is effectively increased, the seedling emergence time is shortened, the germ resistance and the drought resistance capability of the pinus thunbergii are enhanced, leaves of the pinus thunbergii are promoted to grow dark green and luxuriantly, the defoliation rate and the withering rate of the leaves are effectively reduced, the seedling raising quality is greatly improved, and the ornamental value of the potted pinus thunbergii is increased.

Description

technical field [0001] The invention belongs to the technical field of black pine planting, in particular to a potted seedling raising method for increasing the emergence rate of black pine. Background technique [0002] Black pine, also known as white bud pine, is an evergreen tree with a height of up to 30 meters. The bark is gray and black. It is evergreen throughout the year. It has strong resistance to diseases and insect pests. It blooms in April and has single flowers. The female flowers are born on the top of the new buds. It is purple, and most of the scales are heavy and arranged in a spherical shape. When mature, most of the pollen will float out with the wind. The cones will form in the next autumn, and the scales will crack and scatter seeds. The seeds have thin wings, and the umbilicus of the fruit scales has a short navel Prickly; black pine bonsai has strong adaptability to the environment, and can be cultivated in courtyards and balconies. Its branches sprea...

The seeds have thin wings, and the umbilicus of the fruit scales has a short navel Prickly; black pine bonsai has strong adaptability to the environment, and can be cultivated in courtyards and balconies. Its branches spread horizontally, the canopy is like a canopy, the needles are dark green, and the tree looks elegant. It can be admired all year round. During the growth period, it should be placed outdoors Places with sufficient sunlight and air flow should not be placed indoors for a long time. The pile scenery of black pine cultivated for many years, the old stems are vigorous and twisted, and the roots are intertwined. but the emergence rate of potted black pine is not ideal and the emergence speed is slow, which greatly affects the seedling raising effect of potted black pine
