Method for controlling quicksand in cold regions by using dracocephalum heterophyllum plants

Abstract

The invention relates to a method for controlling quicksand in cold regions by using dracocephalum heterophyllum plants. The method comprises the following steps that S1, healthy and strong bunches or seeds of the dracocephalum heterophyllum plants in deteriorated meadows are obtained; S2, dry livestock excrement and surface layer humus soil locally collected from grasslands are collected; S3, the livestock excrement is smashed by utilizing a stirring machine and is evenly mixed with the humus soil to form a coverage material; S4, the bunches of the dracocephalum heterophyllum plants are transplanted to moving dunes, and the root peripheries and the root and stem joint positions are covered with the coverage material, or the seeds of the dracocephalum heterophyllum plants are scattered on the moving dunes and are covered with the coverage material. The method has the advantages that the key material can be obtained locally, operation is simple and convenient, the moving dunes are fixed by using poisonous weeds which livestock do not eat, the biological diversity of the meadows can be ensured, it can be also ensured that the vegetations on the moving dunes are restored and are not destroyed due to treading of the livestock, and quick restoration of grassland vegetations in the cold regions and ecological environment improvement are achieved.

Description

technical field [0001] The invention relates to the technical field of plant propagation and desertification prevention and control, and in particular to a method for controlling quicksand in alpine regions with Cynophyllum heterophyllum plants. Background technique [0002] Chrysanthemum heterophyllum, a perennial herb of Lamiaceae, is born in degraded and deserted alpine grasslands and sandy river beaches. The aboveground part can be used as medicine. The Chinese medicinal material is named Qinglan. Heliconia heterophyllum, square stems, numerous, 2-4mm in diameter, often curved or slightly curved, obliquely upward or sometimes flat on the ground, 5-20cm high, densely covered with white pubescence, usually yellow-green on the surface with purple red, purple at the nodes Darker, firm and brittle, yellowish-white in fracture, white in the center; opposite leaves, basal leaves and lower leaves of stems with long stalks, 2-3cm long, usually purple-red, pubescent; leaves broadl...
