Method for no-tillage plantation of grassland in water-level-fluctuating zone

Abstract

The invention discloses a method for the no-tillage plantation of grassland in a water-level-fluctuating zone. A well-shaped stem pressing method is used for planting herbaceous plants which can be reproduced by creeping stems; and according to the well-shaped stem pressing method, the base ends and top ends of every four detached creeping stems are pairwise crossed into a well shape, four cross points are formed, and are buried into soil, and at least one stem node part of each of the two creeping stems at each cross point is buried into the soil. Compared with the conventional pit planting method, the method is time-saving and labor-saving, the working efficiency is improved, and water and soil loss is reduced; at least two stem node parts of each seedling are buried into the soil, so that the rootage and survival capability of the seedling is improved, the lawn starting speed of the grassland is increased, and the coverage of 80 percent can be reached generally after the grassland is planted for four months; long creeping stems are used as seedlings, so that the using amount of the seedlings is decreased, and the utilization rate of the seedlings is increased; and the seedlings are uniformly arranged along four directions, so that the lawn formation uniformity of the grassland is improved, and soil reinforcement and slope protection effects are enhanced. Therefore, the method is applied to the lawn starting of the soil reinforcement and slope protection grassland in the water-level-fluctuating zone.

Description

technical field [0001] The invention relates to a no-tillage planting method for grassland in a water-fluctuating zone. Background technique [0002] In the grassland construction in our country, it is generally customary to adopt traditional agricultural farming methods, which emphasize full-tillage, multi-tillage, leveling, suppression, removal of stubble, and establishment of artificial grasslands. However, facing the sandy land in the north, the arid and semi-arid grasslands, and the grassy mountains and steep slopes in the south, there are serious soil erosion, and its application is limited, and the achievements are not very great. In the arid wind-sand region in the north, the wind erosion is severe, and the traditional plowing and suppression farming method is difficult to fix the topsoil, so it is very important to protect the original vegetation and soil layer. In the southern grasslands, the grassy slopes are high and steep, with a lot of precipitation. Under the...

Problems solved by technology

Compared with other land resources, the periodic exposure and immersion of land in the hydrofluctuation zone, as well as water erosion and sediment deposition, will cause a series of changes in the topography, soil and water conditions of the hydrofluctuation zone (Battaglia L L, CollinsBS, Linking hydroperiod and vegetation response in Carolina bay wetlands, Plant Ecology, 2006, 184(1), 173-185), many rock masses are often in an alternating state of dryness and wetness, which reduces the overall stability of the rock mass and accelerates landslides, collapses and debris flows, etc. occurrence of natural disasters
