Intercropping method of forest and grass in terraced fields separated by slopes

Abstract

The invention discloses an interval terrace forest and grass intercropping method. The interval terrace forest and grass intercropping method includes: firstly pushing out terraced fields with the width of 4m to 5m on a slope through a bulldozer, wherein the horizontal interval of the terraced fields is 4m to 5m, building high side banks on the outer edges of the terraced fields, and manually tamping the high side banks; then, planting 1 to 2 lines of economic trees in the terraced fields, and planting legume on the outer slope surface; finally digging ditches along peripheries of crowns, and embedding cut legume in soil, and finishing the process of interval terrace forest and grass intercropping. The interval terrace forest and grass intercropping method effectively reduces water and soil loss of the slope, the cut legume can provide organic green manure for orchards, fertilize transportation cost is reduced, legume and fruit trees can be planted separately, healthy growing of fruit-bearing forests can be ensured, pollution-free and sustainable green development can be achieved, and interval terrace forest and grass intercropping is the developing direction of green agriculture and is particularly suitable for being popularized and used in green agriculture economic forest construction of soil mountainous areas.

Description

technical field [0001] The invention relates to a forest-grass intercropping method on a sloping field, in particular to a green and environment-friendly planting method for forest-grass intercropping by using terraced fields separated by slopes, and belongs to the field of plant cultivation. Background technique [0002] Mountain orchard is one of the main measures for the development of mountainous agricultural economy, and it is also a main channel for the broad masses of farmers to make a fortune. However, the mountainous slopes are affected by their own landform conditions, and the soil erosion is serious. In traditional orchard cultivation techniques, narrow terraced fields and narrow terraced fields separated by slopes and reversed slopes are often used. Due to the low design standards of these technologies, narrow terraced fields cannot withstand the damage of terraced fields caused by heavy rainfall, resulting in poor soil and water conservation in mountainous orcha...

Problems solved by technology

Although the research on this type of technology is very active, the research process is rarely combined with reality. For example, the huge cost of building wide terraced fields exceeds the economic input capacity of local farmers, and related technologies have to be promoted by the government. In mountainous areas with thin soil and rocks, it is difficult to carry out mechanized construction, and the construction, use and promotion of wide terraced fields will be seriously affected, which in turn will affect research in other directions based on wide terraced fields; The technology ignores the negative impact on the growth and development of trees caused by competition between pastures and trees for water and fertilizer, resulting in a decline in fruit yield and quality. Related technologies take care of one and lose the other, which has a negative impact on economic forest production
