Embodiment Construction

[0035] The present invention will be further described below in conjunction with embodiment.

[0036] 1. Site selection

[0037] (1) The choice of landform. The formation of subtropical landforms has gone through a long process of geological history. After the Yanshanian movement, the embryonic form of modern landforms was formed. Since the Quaternary, due to strong weathering and denudation, the original uplifted plateaus and mountains were gradually flattened. The undulating mountains, hills, hills, depressions and even plains with the characteristics of weathering and denudation have different morphological ranges and undulating degrees of modern landforms due to different structural shapes and stratum exposure conditions; red rocks are exposed in various In the basin area, the hills and hills are undulating, with rivers, hills, hills and mountains. The rock formations are mostly arranged in layers of shale, mudstone and sandstone. In the area, some honeycomb-shaped slope...

Abstract

The invention relates to a purple soil hilly area gentle slope honeycomb surface forest and grass composite planting high-efficiency utilization method. The method comprises the following steps: (1) a southeastward gentle slope honeycomb surface of a purple soil hilly area is selected as an implementation object; (2) equal-altitude lofting is carried out at the selected slope surface from bottom to top, and working zones are defined, wherein the slope surface has a plurality of horizontal zones; (3) an area with a width of 0.4-0.6m below each working zone is not reclaimed, and the other areas are reclaimed; (4) during the reclamation process, part of honeycomb pits are discarded; for some large honeycomb pits, the bottom parent material is deeply plowed once, and a layer of organic fertilizer is applied; (5) a drainage ditch is dug above each reclaimed zone; soil ridges are built in ditches with certain distances, wherein one soil ridge is built in one ditch; soil obtained by digging is used for flattening the discarded pits; the soil is piled around pits for planting ziziphus jujuba, and organic fertilizer and phosphate fertilizer are spread on the surface of the piled soil; (7) ziziphus jujube is transplanted in the pits; (2) eulaliopsis binata is planted outside the pits; and (8) trifolium repens is sowed all over the orchard. With the method provided by the invention, a large amount of barren and hard-to-utilize land in a purple soil distribution area can be fully utilized.

Description

technical field [0001] The invention relates to a high-efficiency utilization method for compound planting of forest and grass on a honeycomb-shaped slope of a purple soil mound, in particular to a method for efficient utilization of a compound planting of forest and grass on a honeycomb-shaped slope of a gentle slope of a purple soil hill. Background technique [0002] Purple soil is widely distributed in the low hills and valley plains of the basins in southern my country, and the distribution is concentrated in the Sichuan Basin: the soil-forming parent rocks are mostly Cretaceous and Tertiary continental or lacustrine sedimentary materials (purple shale, purple Mudstone, purple sandstone), the occurrence of rock formations is mostly arranged in layers of shale, mudstone and sandstone. [0003] Mudstone and shale are mainly composed of calcareous mudstone minerals, kaolinite, feldspar, etc. The size of the pores is also different, resulting in differences in the specific ...
