Problems solved by technology

Therefore, when herbicides that are routinely applied to crops are applied to sphagnum moss, either the weed control effect is not good, especially for the broad-leaved weeds that are excessively shaded; or the growth of sphagnum moss is seriously affected at the same time, resulting in Sphagnum moss is also killed while controlling grass

Embodiment 1

[0057] A method for controlling field broad-leaved weeds in the early stage of peat moss planting, comprising the following steps:

[0058] (1) Select the plot; the slope is 1° and the soil is directly prepared, the soil is yellow-brown soil, and the pH value is 5.0;

[0059] (2) Soil preparation, clearing the vegetation on the surface; raking the top 8cm of soil and collecting it for later use; plowing the lower 25cm of soil; Excavate the first-level ditch on the periphery, the first-level ditch and the second-level ditch are connected to each other, and retain a water inlet and a water outlet; then cover the top of each compartment with 8 cm of surface soil to be used, and level the land. The first-level water ditch is 40cm wide and 30cm deep, the second-level water ditch is 20cm wide and 25cm deep; the water inlet is located on a high ground, and the water outlet is located on a low ground; after leveling the land, cover it with black plastic film; 10 days before transplant...

Embodiment 2

[0063] (1) Select a plot; with a slope of 9°, the entire plot is formed into several terraced fields according to the height of the terrain, the soil quality is not yellow-brown soil, and the pH is adjusted to 6.5 by applying ferrous sulfate powder;

[0064] (2) Clean up the surface vegetation; rake the top 10cm of soil and collect it for use; plow the lower 30cm of soil; divide the whole land into several compartments; Dig the first-level ditch, the first-level ditch and the second-level ditch are connected to each other, and retain a water inlet and a water outlet; then cover the top of each compartment with 10 cm of surface soil to be used, level the land, and the first-level ditch The ditch width is 50cm, the ditch depth is 40cm, and the secondary ditch is 25cm wide and 35cm deep; the water inlet is located on a high terrain, and the water outlet is located on a low terrain; after leveling the land, cover it with black plastic film; 12 days before transplanting, it will be ...

Embodiment 3

[0068] (1) Select a plot; the soil slope is 30°, and the whole plot is formed into several terraced fields according to the height of the terrain. The soil quality is yellow-brown soil, and the pH value is 7.0;

[0069] (2) site preparation, clearing the vegetation on the ground surface; collecting the 12cm surface soil after raking and crushing; plowing the lower 35cm soil; Excavate the first-level ditch on the periphery of the plot. The first-level ditch and the second-level ditch are connected to each other, and one water inlet and one water outlet are reserved; The first-level ditch is 60 cm wide and 50 cm deep, and the second-level ditch is 30 cm wide and 40 cm deep; the water inlet is located on a high ground, and the water outlet is located on a low ground; cover the land with black plastic film; After uncovering the black mulch film covering the ground, divert water into the canal to submerge the land, drain the remaining weeds after they die, and let the soil dry for ...

Abstract

The invention discloses a method for controlling field broadleaf weeds in the early stage of sphagnum moss planting, and relates to the technical field of sphagnum moss wetland recovery. The method comprises the steps of selecting a plot; preparing a land, and cleaning a soil surface; preparing surface soil and lower soil; arranging the whole plot into a plurality of compartments; digging water channels; leveling the land; overlaying a black mulching film; introducing water to submerge a field; performing airing; transplanting and planting sphagnum moss; and spraying pesticide, namely drainingthe water channels, spraying 37.5-75 g / hm<2> of tribenuron-methyl herbicide at the height of 4-6 cm above the tops of the broadleaf weeds, and introducing water into the water channels again after 20-30 h. The invention also provides application of the tribenuron-methyl herbicide to control of the broadleaf weeds in the early stage of sphagnum wetland planting. The method has the characteristicsof low dosage and high efficiency, does not generate toxic action on the sphagnum while weeding, and is suitable for sphagnum moss wetland recovery dominate in broadleaf weeds.

Description

technical field [0001] The invention relates to the technical field of sphagnum moss wetland restoration, in particular to a method for controlling field broad-leaved weeds in the early stage of sphagnum moss planting. Background technique [0002] Peat moss (Sphagnum spp.), also known as water moss, belongs to the moss family Sphagnum sphagnum. Sphagnum has no roots and vascular tissues, and mainly relies on absorbing water from the ground or the air. Peat moss species grow in wet swales and swamps in mostly acidic growth substrates. There are 250 to 450 species in the world, and there are currently about 41 species in my country. Globally, peat moss wetlands are mainly concentrated between N45° and N70°, and abroad, they are mainly distributed in northern Europe and North America. my country is mainly distributed in temperate regions such as Daxinganling, Xiaoxinganling and Changbai Mountains in the northeast; in subtropical regions, there are also sporadic distributions...
