Description

A kind of karst fissure seeder and sowing method

technical field

The invention belongs to the technical field of soil geology, and in particular relates to a karst fissure seeder and a seeding method.

Background technique

Karst rocky desertification is a special type of land degradation, which is formed by exposed rocks due to forest degradation in humid subtropical regions. The material basis for the formation of karst rocky desertification is carbonate rocks, and lithology has an obvious control effect on the spatial distribution of rocky desertification. Although the topography of the karst area is not undulating, there are rich and diverse niches, such as in a small space. Within the scope, there are dry niches such as stone buds and stone surfaces with exposed rocks and drastic temperature changes, as well as fertile stone ditches and rock crevices with relatively deep soil layers, rich soil nutrients, high organic matter content, and small temperature fluctuations. Habitat. In the process of ecological comprehensive management of karst rocky desertification, the restoration of forest vegetation is fundamental to improve the ecological improvement of karst areas. Karst surface rocks are highly heterogeneous in plant growth ecological space due to rock occurrence and crack size, and soil quality and quantity are different, resulting in great differences in plant productivity. Different rocky desertification sites have different recovery potentials for supporting plants. In the process of restoration and reconstruction of vegetation in karst rocky desertification areas, how to make full use of natural forces, give full play to the role of human subjective initiative, make it technically appropriate, economically feasible, and realize the effective combination of natural habitat and artificial technology is the key to the restoration of vegetation in karst areas. effective way.

In the vegetation restoration and reconstruction of karst difficult sites, a lot of research progress has been made by adopting techniques such as blasting site preparation, alien soil afforestation, fish scale pit site preparation afforestation, root cutting seedling afforestation, container seedling afforestation, rooting powder, and water-retaining agent dipping root afforestation. Although the above vegetation restoration techniques have achieved fruitful results, due to the particularity and complexity of the dual structure of the karst environment itself, how to analyze and utilize its complex and diverse habitats to effectively replenish plant sources in difficult karst sites and carry out vegetation restoration Restoration and reproduction, with the characteristics of less investment, quick results, and easy operation, and actively exploring new methods of vegetation restoration technology on karst difficult sites are of great significance for us to improve the science, rationality, and effectiveness of comprehensive ecological management of karst rocky desertification.

The comprehensive management area of karst rocky desertification is mainly located in the karst ecological fragile zone in southwest my country. ecological environment problems. Since the comprehensive control project of rocky desertification in karst areas is a comprehensive ecological project starting from the prevention and control of rocky desertification and soil erosion (but not with the sole goal of rocky desertification prevention and control), under the premise of emphasizing comprehensiveness, it must focus on Highlight the role of governance projects in the prevention and control of rocky desertification and control of soil erosion. Therefore, promoting vegetation recovery and reconstruction in karst areas is not only the key to preventing rocky desertification and controlling soil erosion, but also the most important way of governance projects. The planting of plants in artificially promoted restoration and reconstruction is essential. How to use planting tools in rugged mountainous areas to carry out reasonable and effective planting, accelerate the construction of ecological environment in karst areas, promote regional social and economic progress, and realize the coordination of ecological economy in karst areas It has important practical significance to the sustainable development of regional economy.

Contents of the invention

The object of the present invention is to provide a karst fissure seeder and a sowing method, so that the fissure habitat in the karst area can reasonably and effectively obtain plant provenance, the operation is simple, the method is easy to implement, and manpower and material resources are saved, and it can be widely used in karst with extreme exposed rocks. Large-scale plant restoration and afforestation in the region is a better seedling breeding method for promoting afforestation and rocky desertification ecological control in karst areas, and is of great significance for plant restoration and ecological environment construction in karst areas.

The purpose of the present invention and its main technical problems are achieved by adopting the following technical solutions: a karst fissure sower, characterized in that it includes a sowing handle, a sowing cylinder and a sowing retrieval rod, and the sowing handle is welded to the upper end of the sowing cylinder. The two sides are fixedly connected, and the lower end of the seeding tube is inclined; the upper end of the sowing probe rod is connected with a sowing probe rod transverse force rod, and the lower end has a sowing probe rod piston.

The above described karst fissure seeder is characterized in that: the length of the sowing probe rod is 10-15 cm longer than that of the seeding tube, and the sowing probing rod is separated from the seeding tube.

The sowing method of a karst fissure seeder is characterized in that: firstly, a seeding cylinder is used, and the slope of the seeding cylinder is inserted into the soil of karst fissures through the focus point of the sowing handle, and the insertion depth needs to be covered according to the size of the plant seeds. Depending on the thickness of the soil layer, squeeze the seeding handle, pull out the seeding tube, push out the soil in the seeding tube through the sowing probe rod, then insert the seeding tube into the sowing hole, put the plant seeds from the upper end of the seeding tube, and then push out Put the soil into the seeding tube, insert the sowing probe rod into the sowing tube, compact the soil, let the plant seeds be in close contact with the soil, and then pull out the sowing tube, use the sowing probe rod to remove all the soil and plant seeds in the sowing tube Push it into the sowing hole, and the sowing process of the sower has just been completed.

Compared with the prior art, the present invention has obvious advantages and beneficial effects. It can be seen from the above technical scheme that the present invention can play an important role in sowing and afforestation in karst areas with extremely exposed rocks. It can not only ensure that plant seeds are effectively sown into karst crevice habitats, improve the germination rate of plant seeds, but also make germinated plants The seedlings can fully absorb the nutrients in the karst fissure habitat, promote the growth of the seedlings, and accelerate the recovery of the karst forest vegetation. The invention is economical, applicable, simple, portable and easy to operate for seeding and afforestation in the extremely exposed rock karst area.
