specific Embodiment approach 1

[0013] Specific implementation mode 1: The method of returning farmland to wetland in this implementation mode to quickly revert to S. orientalis wetland is implemented in the following steps:

[0014] 1. Plant selection and collection: In the distribution area of ​​S. orientalis (high density) in natural wetlands, select the S. orientalis community that has grown for 2 to 4 years as the transplanting body, and use the method of interval excavation to carry out the transplantation of the S. orientalis Excavation, the root system of S. orientalis has the undisturbed soil, and then the undisturbed soil of the transplanted S. orientalis is cut into blocks with a diameter of 10-15cm, and the blocks are kept as complete as possible to maintain the integrity of the main root system and placed in a woven bag Keep moisturizing for use to obtain the transplanted body of Scirpus orientalis;

[0015] 2. Land consolidation: carry out shallow plowing of the converted farmland to wet fields, wit...

specific Embodiment approach 2

[0022] Specific embodiment two: This embodiment is different from the specific embodiment one in that in step one, the S. orientalis community that has grown for 3 years is selected as the transplanting body.

specific Embodiment approach 3

[0023] Specific embodiment three: This embodiment is different from specific embodiments one or two in that in step one, a sharp spade or flat sharp steel is used to excavate the transplanting body of S. orientalis.

Abstract

The invention discloses a method for rapidly recovering paddy field pieces of wetland reverted by cultivated land into eastern meadow rush wetland, and belongs to the technical field of ecological engineering. The problems that in the natural recovery process of vegetation of paddy field pieces of wetland reverted by cultivated land, the recovery period is long and the stability is poor are solved. The method for rapidly recovering paddy field pieces of wetland reverted by cultivated land into eastern meadow rush wetland comprises the steps that 1, an eastern meadow rush transplanting body isdug, and the root system of eastern meadow rush carries original soil; 2, shallow reversing is performed on the paddy field pieces of wetland reverted by cultivated land; 3, the eastern meadow rush transplanting body is planted into a planting pit; 4, after transplanting, water is supplemented, and water is supplemented till the ground surface water depth reaches 1-3 cm; 5, after creep branch tipnewly-born plant bodies grow to 70-95 cm, creep branches are cut off, newly-born plant bodies of separated mother plant bodies grow and expand to be propagated, within one to three years, the newly-born plant body and mother plant body separating process is repeatedly performed, and natural growth and propagation of eastern meadow rush are kept. By adopting manual assistance for separation of creep branches and newly-born plant bodies, the newly-born plant body wild expanded propagation and multiplication capability is enhanced, and the recovery efficiency is improved.

Description

Technical field [0001] The invention belongs to the technical field of ecological engineering, and in particular relates to a method for returning farmland to wetland plots to quickly restore to oriental scrips wetland. Background technique [0002] Wetland is the most biologically diverse ecological landscape in nature and one of the most important living environments for mankind. Wetland plays an important role in maintaining regional ecological balance and protecting biodiversity. However, due to the impact of climate change and human activities, the wetland landscape has undergone significant changes. Especially as the contradiction between population growth and shortage of land resources has become increasingly prominent, wetlands have been reclaimed on a large scale, and the structure of wetland ecosystems caused by wetland farming has been destroyed, functional decline, biodiversity reduction, biological productivity decline, and wetland resources gradually The loss of a ...
