Abstract

The invention provides a spray-seeding revegetation method for riverbeds in a high elevation region, and relates to the technical field of sand prevention and fixation. The method comprises the stepsthat 1, construction is prepared in dry season of a river; 2, before spay-seeding construction, the construction region is prepared, the to-be-constructed region is leveled, and garbage is removed; 3,a sand-fixation substrate is spray-seeded, where in 15-40% by volume of deep clay soil, 20-35% by volume of humic acid, 0.1-2% by volume of pellet agent, 0.5-3.0% by volume of polymer binder, 30-45%by volume of wood meal, 5-10% by volume of distillers' grains, 3-5% by volume of organic fertilizer and 0.4-2.5% by volume of seeds are mixed to be uniform to be prepared into the sand fixation substrate, and the sand fixation substrate is put into a spray-seeding machine and sprayed out uniformly; 4, the spray-seeding thickness is 2-3 cm, and the spray-seeding thickness is uniform. Accordingly, the sand fixation substrate has the advantages of being resistant to long-time water erosion and periodical hydrodynamic force, high in capacity of resisting wind erosion, high in fixed capacity, highin vegetation survival rate, small in preservation difficulty and low in cost.

Description

technical field [0001] The invention relates to the technical field of sand prevention and sand fixation, in particular to a spraying greening method for riverbeds in high-altitude areas. Background technique [0002] The Yarlung Zangbo River (referred to as the Yarlung River) is the longest plateau river in China and the largest river in the Tibet Autonomous Region. It is 2091km long in China, with a drainage area of ​​238,000 square kilometers and an average annual flow of 139.5 billion m 3 , accounting for 1 / 20 of the river runoff in my country, second only to the Yangtze River and the Pearl River, ranking third in the country's rivers. The Yajiang River is divided into a wet season and a dry season. The wet season is from June to September, and the dry season is from October to May of the following year. According to the meteorological data statistics of Gongga Meteorological Station in Shannan area, the annual average wind speed in this area is 4m.s -1 , the average s...
