A kind of high ridge cultivation method of braided willow beach

Abstract

The invention discloses a method for cultivating willow trees with high ridges at bottomland. In the bottomland drowned for a short time in the flood period, a high-ridge cultivation technology is adopted to cultivate willow trees, and a cofferdam is constructed at the periphery of the cultivation region, wherein the ridge construction direction is parallel to a river embankment. Besides the characteristics of traditional high-ridge cultivation, the willow tree high-ridge cultivation technology also has a better waterlogging prevention function and a better soil moisture preservation function, and is applicable to developing the agriculture and forestry in a low-humidity bottomland. According to the method, the ridges are formed in a direction parallel to the river embankment, the heights of the ridges are gradually increased along with decrease of terrain, the ridges formed at relatively low positions are higher, and the ridges formed in relatively high positions are lower, so that the horizontal plane change of a knitting willow tree planting region is less, the survival rate is well improved, the growth is promoted. According to the knitting willow tree high-ridge cultivation technology, the ridges face towards a direction parallel to a watercourse, flood draining in the flood period is facilitated and waterflood is prevented from washing away the planting ridges.

Description

technical field [0001] The invention belongs to the field of weaving willow cultivation, and relates to a method for cultivating willows in high ridges on beaches. Background technique [0002] There are more than 900,000 hectares of beach land in the middle and lower reaches of the Yangtze River, most of which are in a barren and semi-barren state and urgently need to be treated and developed. According to the study, the development and utilization of tidal land resources should be combined with river regulation, economic construction, schistosomiasis prevention work and wetland protection, and be implemented step by step according to local conditions, scientific planning, and gradually establish a multi-functional and multi-benefit complex integrating production, protection and recreation. The comprehensive system can better play the role of the golden waterway in the national economic construction of the whole region and even the whole country. [0003] The middle and lo...

Problems solved by technology

[0005] At present, there are three main problems in planting woven willow in the Yangtze River beach: 1) Under the flooding conditions of the Yangtze River flood season, natural willow forests are grown mainly by natural conditions, and the survival rate and growth rate are reduced; stable operation cannot be guaranteed, and the benefits are not high ; 2) The river beach faces the problem of water body protection

[0007] High ridges are built perpendicular to the embankment. Because the ridges are perpendicular to the embankment, during the rainy season or flood season, the water in the ridge can easily form high-speed scouring runoff, resulting in serious erosion of the ridge and the embankment. Because the direction of the ridge is inconsistent with the direction of water flow, Not conducive to flood discharge during flood season
