specific Embodiment approach 1

[0015] Specific implementation mode 1: In this implementation mode, the method of returning farmland to wetland by utilizing the nectar source plant Stachyssois is carried out according to the following steps:

[0016] 1. Reorganization of the returned farmland plots: set up cofferdams around the returned farmland plots, detoxify the returned farmland plots, and then plow them;

[0017] 2. Transplanting seedlings: Transplant Shuisu seedlings with a plant height of 10-20cm into the plots that have been sorted out;

[0018] 3. Water management: water the Shuisu seedlings immediately after transplanting, and check the soil moisture status every other day to keep the water content at 60-100% of the saturated water holding capacity of the soil; after the seedlings grow for 25-35 days, keep returning to the farmland The surface water depth of the plot is 0.1-20cm; that is, the conversion of farmland to wetland has been completed.

[0019] Step 1 of this embodiment is to set up a co...

specific Embodiment approach 2

[0022] Embodiment 2: This embodiment differs from Embodiment 1 in that the height of the cofferdam in step 1 is 5-30 cm higher than the surface of the degraded land, and the width of the lower part of the cofferdam is 30-50 cm. Others are the same as the first embodiment.

specific Embodiment approach 3

[0023] Specific embodiment 3: The difference between this embodiment and specific embodiment 1 or 2 is that in step 1, Wotuan is used for detoxification, and the dosage of Wotuan is 400-600 g / mu. Others are the same as those in Embodiment 1 or 2.

Abstract

The invention relates to a method for returning grain plots to wetlands by using nectariferous plant namely stachys baicalensis herbs. According to the method, the problem that the restoration successrate of stachys baicalensis herbs is low is solved. The method disclosed by the invention comprises the steps of I, finishing plots returned from grain plots ; II, transplanting seedlings; and III, performing water management. According to the method for returning grain plots to wetlands, the survival rate of the stachys baicalensis herbs is high, the effect of returning grain plots to wetlands is good, and the method is simple to operate and favorable for popularization.

Description

technical field [0001] The invention relates to a method for returning farmland to wetlands. Background technique [0002] Wetlands are one of the three major types of ecosystems in the world. They play an irreplaceable role in regulating floods, regulating climate, degrading pollution, maintaining biodiversity and regional ecological balance. However, in the past few hundred years, wetlands have been severely damaged, the area of ​​wetlands has been greatly reduced, and their functions have declined. Human irrational economic activities are the main reason. For example, large-scale reclamation of wetlands has led to a series of problems such as the destruction of the wetland ecosystem structure, the reduction of biodiversity, the decline of vegetation productivity, and the gradual loss of wetland resources. In order to strengthen the protection and restoration of wetlands, my country mainly adopts measures such as returning farmland to wetlands and restoring drained and de...
