Problems solved by technology

The main pests in the cultivation of white bone soil seedlings are leaf tortrix and larvae of Boreridae, and the harmful parts are their leaves. Traditionally, broad-spectrum insecticides are sprayed to control them, but they have certain drug resistance, and the amount of pesticides used is large and has certain toxicity. The environment is not friendly enough
In addition, during the seedling raising process, the cotyledons or the base of the seedlings ar

Abstract

The invention provides an avicennia marina seedling raising method which comprises the following steps: (1) selecting avicennia marina seeds in a mature period, soaking the avicennia marina seeds in water, soaking the avicennia marina seeds in 3-5 wt% of 400-600-fold solution of celastrus angulatus wettable powder for 3-5 minutes, and draining the avicennia marina seeds; (2) taking the seeds treated in the step (1), adding a seed protective agent prepared from a green orange seed extract, limonin and sodium tetraborate according to the mass ratio of (0.6-0.7): (0.3-0.4): 1; mixing the seeds with the seed protective agent and then carrying out sowing; (3) spraying 800-1000 times of equivalent Bordeaux mixture on cloudy days or rainy days during seed germination; and (4) when the avicennia marina seedlings grow to more than 50 cm, harvesting the seedlings. By the adoption of the seedling raising method, the outplanting rate of healthy avicennia marina seedlings is increased, the seedling quality is improved, the disease resistance of the avicennia marina is improved, the afforestation quality of the avicennia marina is remarkably improved, and meanwhile the method is more friendly to the ecological environment.

Description

technical field [0001] The invention relates to the technical field of white bone soil, in particular to a method for growing seedlings with white bone soil. Background technique [0002] Bone soil, Latin name: Avicennia marina (Forsk.) Vierh., also known as marina marina. Verbenaceae Dietera. Shrubs or small trees, 2-3m high, up to 8m or more. The branches have raised stripes, the branchlets are square, the leaves are nearly sessile, leathery, ovate to obovate, elliptic, the apex is blunt, the base is wedge-shaped, the surface is glabrous and shiny, the back has fine and short hairs, the main vein is obvious, clustered The cymes are tightly head-shaped, the flowers are small, about 5 mm in diameter, the fruit is nearly spherical, about 1.5 cm in diameter, hairy.
