Problems solved by technology

The above-mentioned method can carry out afforestation on the beach, and can play a role in reducing the salt content of the saline-alkali land, but it still cannot make a variety of ecological landscape type shelterbelts grow rapidly.

Embodiment 1

[0030] Embodiment 1: a kind of method for quickly constructing the ecological landscape type shelterbelt on the newly reclamation tidal flat, at first to need reclamation tidal flat, utilize mechanical device, tidal flat land is excavated, turned over, loosen soil, breaks the tidal flat salt barrier; Excavation The time for digging the soil is 2 years earlier than the time for excavating the main river channel. The time for excavating the soil is every autumn. Loosen the soil "frozen". Because there is a layer of highly viscous impermeable soil at the bottom of the tidal flat, and the salt in the tidal flat soil is easy to accumulate above the impermeable soil when it permeates downward under the action of water flow, forming a "salt barrier". Therefore, in this area, the salt content in the soil is extremely high. For the salinity in this part of the soil, if the soil is not excavated, the phenomenon of salt return will easily occur after the planting soil is piled up in the...

Embodiment 2

[0034]Embodiment 2: A kind of method for quickly constructing the ecological landscape type shelterbelt on the new reclamation tidal flat, all the other steps are the same as embodiment 1, since 2012, in Taizhou Shitang new reclamation tidal flat, construction shelterbelt area 700 mus, but used for The base soil for blocking salt is set as viscous green silk mud, that is, the cohesive soil dug out from the bottom of the desalinated river, which is used to block saline soil and prevent salt return. The best planting soil, such as yellow soil, is stacked with a thickness of 1 meter. Use yellow soil and "green silk mud" directly to raise the afforestation ground, and then plant excellent landscape tree species on the yellow soil at intervals, such as Sapindus chinensis and Huangshan eucalyptus , ginkgo, camphor tree, hackberry, cypress, privet, elm, hibiscus, slash pine, Podocarpus, through the above method, after four years, the preservation rate of the forest protection belt is ...

Embodiment 3

[0035] Embodiment 3: a kind of method of constructing the ecological landscape type shelterbelt rapidly on new reclamation tidal flat, all the other steps are with embodiment 1, since 2012, in the new reclamation tidal flat of Shiyitang, Taizhou, construction shelterbelt area 200 mus, but use The base soil for blocking salt is set as a mixture of yellow soil and fly ash, with a stacking thickness of 1.5 meters. Fly ash is fine ash collected from the flue gas after coal combustion. The main solid waste discharged from coal-fired power plants, the oxide composition of fly ash in thermal power plants is: SiO 2 、Al 2 o 3 And a small amount of FeO, Fe 2 o 3 , CaO, MgO, SO 3 、TiO 2 etc., where SiO 2 and Al 2 o 3 The content can account for more than 60% of the total content. It is better to use the mixed soil mixed with yellow soil and fly ash to block the saline soil and prevent salt return; then pile paddy soil on the mixed soil mixed with yellow soil and fly ash, The sta...

Abstract

The invention discloses a method for quickly building an ecological scenery type protective forest belt on a new reclamation mud flat, and belongs to the technical field of agricultural cultivation. The method comprises the following steps of A, conducting mechanically digging soil and turning soil and breaking mud flat salt isolation; B, digging a trunk riverway and building an ecological bank; C, combining multiple kinds of soil and improving soil natures; D, planting scenery tree varieties. By means of the method, mud flat salt isolation is quickly broken, soil salt-leaching is accelerated,the ecological scenery type protective forest belt is quickly built on the new reclamation mud flat, the afforestation survival rate is high, and the method meets new reclamation mud flat scenery tree variety quick setting requirements, can be applied and popularized on a large scale and is significant in accelerating coastal mud flat development and environmental improvement.

Description

technical field [0001] The invention belongs to the technical field of agricultural cultivation, and relates to a method for constructing a shelterbelt on coastal tidal flats, in particular to a method for rapidly constructing an ecological landscape type shelterbelt on newly reclamation tidal flats. Background technique [0002] Coastal tidal flats include four basic types: mudflats, sandy beaches, rocky beaches and biological beaches. Mudflats along the coast are growing silted up every year. Therefore, developing tidal flat resources and reclaiming land from the sea to increase the land area is an important measure for the development of the national economy. [0003] In coastal mudflats, due to the high salinity of the soil, generally only some low salt-alkali-tolerant plants can grow, including some bulbous herbs and some low shrubs, such as reeds, Suaeda salsa, etc., so the ecological landscape is single . [0004] In the newly reclamated tidal flats along the coast,...
