Embodiment 1

[0018] Provide a method for returning farmland to rebuilding the Wetland of P. chinensis, the steps are as follows:

[0019] Step 1: Soil preparation. The time for soil preparation is mid-to-late July of that year. The method and method of soil preparation is to use a rotary tiller to carry out the operation. The depth of the soil is 10-20cm, and the rotary tillage is performed 1-4 times. Through rotary tillage, on the one hand, the original above-ground plants are broken, and on the other hand, it plays a role in leveling the land. The above-mentioned time, method and method of land preparation were chosen mainly because after the cultivated land was returned to farmland, its surface vegetation was dominated by forb grass meadows such as Artemisia and Setaria, and the vegetation grew lushly. In addition, in terms of time selection, these pioneer plants did not form at this time. The seeds or seeds are still immature, destroying the reproductive life history of these weeds; in...

Embodiment 2

[0027] Provide a method for returning farmland to rebuilding the Wetland of P. chinensis, the steps are as follows:

[0028] Step 1: Soil preparation, the time for soil preparation is the middle and late July of the year; the method and method of soil preparation is to use a rotary tiller to carry out the operation, the depth of the soil is 10-18cm, and the rotary tillage is performed 2 to 4 times. Through rotary tillage, on the one hand, the original above-ground plants are broken, and on the other hand, it plays a role in leveling the land. The above-mentioned time, method and method of land preparation were chosen mainly because after the cultivated land was returned to farmland, its surface vegetation was dominated by forb grass meadows such as Artemisia and Setaria, and the vegetation grew lushly. In addition, in terms of time selection, these pioneer plants did not form at this time. The seeds or seeds are still immature, destroying the reproductive life history of these...

Embodiment 3

[0036] Provide a method for returning farmland to rebuilding the Wetland of P. chinensis, the steps are as follows:

[0037] Step 1: Soil preparation. The time for soil preparation is mid-to-late July of that year. The method and method of soil preparation is to use a rotary tiller to carry out the operation. The depth of the soil is 10-15cm, and the rotary tillage is performed twice. Through rotary tillage, on the one hand, the original plants on the ground are broken, and on the other hand, it plays the role of leveling the land. The above-mentioned time, method and method of land preparation were chosen mainly because after the cultivated land was returned to farmland, its surface vegetation was dominated by forb grass meadows such as Artemisia plants and foxtails, and the vegetation grew luxuriantly. In addition, in terms of time selection, these pioneer plants did not form at this time. The seeds or seeds are still immature, destroying the reproductive life history of the...

Abstract

The invention discloses a method for returning farmland to reconstruct deyeuxia angustifolia wetlands. The method includes the steps that 1, field preparation is carried out in mid-to-late July of thecurrent year, and a rotary cultivator is adopted for operation, wherein the ploughing depth is 10-20 cm; 2, 5-8 days before transplanting of deyeuxia angustifolia plants, the flattened abandoned farmland is irrigated with water, wherein the infiltration depth of soil is 5-10 cm; 3, deyeuxia angustifolia swamp meadow wetlands are adopted as the main parts, wherein the water content of the soil ofthis kind of wetlands is 70%, seasonal ponding to the earth's surface is achieved, the digging area of one sample block is 0.16-0.25 m<2>, the spacing between every two sample blocks is at least 1 m,the digging depth is 5-20 cm, and digging is carried out in mid-to-late August; 4, a sample cutting device is adopted for dividing the dug deyeuxia angustifolia sample blocks into multiple small blocks which are suitable for transplanting, wherein the area of each small block is 0.006-0.01 m<2>; 5, transplanting is carried out in early September, a manual insertion mode is adopted for planting, and the small deyeuxia angustifolia blocks cut in step 4 are planted into the soaked soil, wherein the transplanting depth is 5-15 cm; 6, the line spacing is set from 25 cm to 50 cm; 7, maintenance management in the later period is carried out and mainly includes periodic irrigation, and an alternate drying and wetting mode is adopted.

Description

technical field [0001] The invention relates to a method for returning cultivated land to rebuilding the wetland of P. chinensis, and belongs to the technical field of methods for rebuilding the wetland of P. chinensis. Background technique [0002] Wetlands are an important part of the terrestrial ecosystem, known as the "kidney of the earth", the "storage" and "purifier" of water resources, and the habitat, migration, and overwintering necessary for many rare and endangered species, especially endangered and rare waterfowl. It has multiple functions such as protecting biodiversity, regulating runoff, improving water quality, and regulating microclimate. [0003] However, with the needs of economic and social development, human activities represented by agricultural reclamation and grazing have led to a sharp decline in the wetland area. Taking the Sanjiang Plain wetlands as an example, the area of ​​natural wetlands has decreased from 5.34 million hectares in the early da...
