Agricultural land and river course plant shore protection method

Abstract

A farmland and watercourse plant bank protection method is characterized by comprising the following steps: selecting small arbors with a root system capable of enduring long-term water flooding; culturing the arbors in a seedling period and filling the gaps with seedlings in time; removing trunks, culturing branches and pruning the branches in proper seasons; and finally culturing a plurality of shrubberies which are 1.5-2m tall and form a continuous shrubbery plant community for bank protection. Compared with the prior art, the plant bank protection method has the advantages that: the developed and humidity resistant root systems can form a stable growth zone along water, which plays a role of fixing bank soil and eliminating surge erosion and prevents river water from eroding the bank soil; meanwhile, the growth zone does not affect daylighting of the farmland, does not occupy the farmland, can play a role of afforestation, and has low cost and convenient subsequent management and maintenance.

Description

technical field [0001] The invention relates to a bank protection method for a rural field river, in particular to a plant ecological bank protection method for a rural field river using plant roots. Background technique [0002] Rural field rivers are different from towns and roadside rivers in that they occupy less land, are steeper, and are non-continuous. They play important roles in farmland drainage and irrigation, field microclimate adjustment, etc., and play a vital role in optimizing the farmland ecological environment. effect. Due to the needs of basic farmland area protection, field lighting and input costs, it is impossible to adopt the traditional method of building cement and block stone bank revetment, or plant large trees and lawns for green bank revetment, and the cost of building cement and block stone bank revetment is relatively high.

Problems solved by technology

Due to the needs of basic farmland area protection, field lighting and input costs, it is impossible to adopt the traditional method of building cement and block stone bank revetment, or plant large trees and lawns for green bank revetment, and the cost of building cement and block stone bank revetment is relatively high. The river ecology brings adverse effects. The root system of large trees occupies a large area and is not conducive to daylighting. Lawn greening requires a relatively flat growth surface, which cannot be achieved on the banks of farmland. Second, it requires a lot of labor to water and Subsequent management and maintenance, such as weeding, are costly and cannot be widely promoted

[0003] At present, there are basically no effective bank protection measures for rural rivers in the field, and there are no relevant literature reports on effective technologies in this field. What we can see is that a large number of natural muddy river banks often have landslides and collapses under the erosion of water flow. Not only A large amount of high-quality farmland has been eroded, and it has also led to silting and swamping of farmland rivers, seriously affecting functions such as flood discharge, irrigation and drainage, and bringing great hidden dangers to the safety of the farmland ecological environment.
