Description

Technical Field

[0001] The invention relates to the field of rocky desertification area management, in particular to a rocky desertification area biological management method. Background Art

[0002] Rocky desertification, also known as stony desertification, refers to the phenomenon of surface soil loss, exposed bedrock, loss of agricultural utilization value of land and ecological environment degradation due to soil erosion. Rocky desertification mostly occurs in limestone areas, where the thickness of the soil layer is mostly less than 10cm, and the surface presents an evolutionary process of gradually exposed rocks similar to desert landscape. In terms of causes, the main factor leading to rocky desertification is human activities. Due to the long-term continuous destruction of natural vegetation and large-scale reclamation of steep slopes, the surface is exposed. In addition, the karst rocky mountain area has a thin soil layer, exposed bedrock, and strong scouring force of heavy rain. After a large amount of soil and water loss, the rocks gradually become exposed, thus presenting the phenomenon of rocky desertification.

[0003] In rocky desertification areas, the effect of vegetation locking in water and soil is poor in the early stage after planting, making it easy for it to be moved by flowing water and soil during irrigation and rain, making the planted vegetation unable to survive, which in turn affects the survival of vegetation. Therefore, it is necessary to propose a biological control method for rocky desertification areas. Summary of the invention

The site selection of planting sites includes extensive selection of planting sites, hydrological information query of planting sites, and optimal planting sites. Extensive selection of planting sites is to select a batch of land suitable for planting vegetation in the rocky desertification area. Hydrological information query of planting sites is to query the traffic conditions, precipitation, light, soil fertility, and wind information of the location of the land suitable for planting vegetation. The optimal planting site is to select the planting site with excellent conditions according to the information of hydrological information query of planting sites. Planting vegetation selection includes planting condition information, vegetation selection, and vegetation selection. Planting condition information is to enter the hydrological and environmental information of the planting site after selecting the planting site with excellent conditions. Vegetation selection is to select a variety of vegetation suitable for planting in the site according to the hydrological and environmental information. Vegetation selection is to select suitable vegetation that meets its own needs from the various vegetation that can be planted in the planting site, as well as vegetation that can complement the main planting vegetation. Planting site processing includes planting pit marking, planting pit digging and soil analysis and processing. Planting pit marking is to mark the pits to be dug on the planting site according to the planting spacing requirements of the planted vegetation. Planting pit digging is to dig pits at the marked positions according to the planting depth requirements of the planted vegetation. Soil analysis and processing is to analyze the excavated pit soil and determine whether it meets the requirements for planting, and to carry out targeted processing according to the defects. Vegetation planting and maintenance include plant reinforcement and water and fertilizer spraying. Plant reinforcement is to support and protect the vegetation by forming a bracket with wooden sticks, and water and fertilizer spraying is to mix fertilizer with water and use it to irrigate the vegetation.

[0016] Among them, the widely selected planting sites are selected from the periphery of the rocky desertification areas and the surrounding areas of the rocky desertification areas, and are selected based on the transportation conditions and hydrological conditions to facilitate the subsequent maintenance of vegetation.

[0017] Among them, the preferred planting sites are those areas that meet their own planting area requirements and prioritize solving the direction of the spread of desertification.

[0018] Among them, when the soil analysis treatment cannot lock in moisture, mud and straw slurry can be mixed into mud and straw, and the mud and straw slurry can be applied on the inner wall of the foundation pit.

[0019] The planting condition information is the information on the conditions required for plant growth and the planting advantage information collected from the preferred planting sites.

[0020] Among them, vegetation selection is to select vegetation that meets the planting conditions of the area through the information on growth conditions, and give priority to vegetation that meets the planting advantage information.

[0021] The wooden sticks used for implant reinforcement are tree branches, and the tree branches are dry and can be quickly degraded.

Then, based on its own financial conditions, area requirements, subsequent expansion needs, and emergency prevention and reinforcement needs of water and soil, the area suitable for planting vegetation can be optimized. Then, the precipitation, light, soil fertility, wind information and irrigation conditions of the selected planting area can be summarized, and the most superior conditions can be extracted from them. Then, based on the information and superior conditions, a variety of vegetation suitable for planting in the area can be selected. Then, among the multiple vegetation, vegetation that meets the planting economic conditions and meets the planting needs can be selected. Multiple selections can be made based on the selected vegetation that can be cyclically complementary. Then, when planting, When planting, you can determine the location according to the planting interval requirements of the vegetation, then dig a pit at the designated location, and then mix the soil and broken straw to make mud-straw slurry, and smear the mud-straw slurry on the inner wall of the foundation pit, so as to form an isolation layer within a certain period of time to lock water when the vegetation has not grown up. After the planting of the vegetation is completed, the branch ends of the branches can be inserted into the soil of the foundation pit, and the top ends can be used to reinforce the branches of the vegetation by forming a fixed frame between each other. At this time, when the roots of the vegetation are not fully developed, the soil is blocked and reinforced to a certain extent, and the dry branches will rot after a period of time and provide nutrition for the development of the vegetation. During the growth process, fertilizer and water can be mixed, and then the fertilizer and water can be directly transported for irrigation, so that the fertilization and irrigation processes are integrated, which is convenient for the survival of vegetation and soil and water reinforcement to prevent loss.
