Embodiment 1

[0039] Embodiment 1, application rhizome wheatgrass rehabilitates the saline-alkali meadow that the west of Jilin Province degenerates

[0040] 1. Timely land preparation

[0041] At the beginning of May (when the grassland has turned green), the degraded salinized meadow (pH value between 7.1-8.5) in the west of Jilin was shallowly plowed and leveled, and then the automatic plow was used to plow out parallel shallow furrows. The depth of the ditch is 10cm, the width of the ditch is 15cm, and the ditch distance is 40cm, which is ready for transplanting the rhizome section.

[0042] Two, the collection of the rhizome section of rhizome wheatgrass

[0043] The rhizome segments of Agropyron rhizome were collected in the natural grassland where Agropyron rhizome is distributed in patches in the west of Jilin. When collecting, collect in strips parallel to each other, the width of the strip is 20cm, the depth of the strip is 15-20cm (that is, the depth of the distribution of rhiz...

Embodiment 2

[0051] Embodiment 2, application rhizome wheatgrass repairs the degraded sandy land in the west of Jilin Province

[0052] 1. Timely land preparation

[0053] At the beginning of May (the grassland has turned green at this time), plow parallel shallow furrows with an automatic plow on the degraded sandy land in western Jilin. The depth of the furrow is 15cm, the width of the furrow is 15cm, and the distance between the furrows is 50cm. be ready.

[0054] Two, the collection of the rhizome section of rhizome wheatgrass

[0055] Same as Step 2 of Example 1.

[0056] Three, the treatment of the rhizome section of rhizome wheatgrass

[0057] Same as Step 3 of Example 1.

[0058] 4. Transplanting

[0059] Same as Step 4 of Example 1.

[0060] 5. Post-management

[0061] After transplanting, pay close attention to the germination of buds on the rhizome segment and the growth of seedlings. There is little rain in spring in western Jilin. If it does not rain, water should be r...

Embodiment 3

[0062] Embodiment 3, application of rhizome wheatgrass and rhizome type grass (Leymus chinensis) to repair the degraded meadow steppe in the west of Jilin Province

[0063] 1. Timely land preparation

[0064] At the beginning of May (when the grassland has turned green), shallow plowing and leveling were carried out on the degraded meadow steppe in the west of Jilin, and then the automatic plow was used to plow out parallel shallow furrows with a depth of 15cm and a width of 15cm , the furrow distance is 40cm, ready for transplanting the rhizome segment.

[0065] Two, the collection of the rhizome section of rhizome wheatgrass

[0066] Same as Step 2 of Example 1.

[0067] Three, the treatment of the rhizome section of rhizome wheatgrass

[0068] Same as Step 3 of Example 1.

[0069] Four, the collection of the rhizome segment of rhizome type grass

[0070] The rhizome segments of rhizome-type grasses were collected in the natural grassland where rhizome-type grasses are ...

Abstract

The invention discloses a deplete grassland repairing method. The method includes the following steps: (1) in the period of grass seeding establishment, ploughing grooves with depths of 10-15 cm on to-be-repair land which is deplete grassland, (2) transplanting rhizomatic sections of agropyron michnoi to the grooves ploughed in the step (1) and managing normally; and rhizonmatic sections meet the following conditions (a), (b) and (c) which are (a) individual rhizomes, (b) with lengths of 5-30 cm and (c) with at least one tillering node active bud and / or at least a rhizomatic active bud and / or at least one tillering node winter sprout and / or at least one rhizomatic winter sprout. With the deplete grassland repairing method, problem that perennial vegetations are hard to plant quickly on the deplete grassland in a short term is solved, vegetation coverage of deplete grassland or sandland can remarkably increased, physical and chemical property can be improved, ecological environment of deplete grassland are improved and protected, and integrated economic, ecological and social efficiency is improved.

Description

technical field [0001] The invention relates to a method for repairing degraded grassland, in particular to a method for repairing degraded grassland by utilizing the rhizome section propagation technology of rhizome ice grass. Background technique [0002] Grassland degradation is a process of changing and decreasing comprehensive indicators such as grassland vegetation species composition, quantity, productivity and environment. The yield of edible pasture decreased; the habitat conditions deteriorated, the ground was bare, the soil was dry, desertified and salinized. At the World Grassland and Grassland Conference (IGC&IRC) held in 2008, the conference report "China Grassland Research and Development" made by many Chinese scholars pointed out that due to global warming, climate drought and other natural factors and human overuse and other factors At present, 90% of the natural grasslands in China have been degraded to varying degrees. In recent years, China's grasslands...
