Psammophyte cultivation device and method

Abstract

The invention provides a psammophyte cultivation device and method and belongs to the field of psammophyte cultivation. The cultivation device comprises a sleeve, a drill bit and a transmission shaft;the transmission shaft is connected with the drill bit, the transmission shaft is used for transmission connection with a driving device, and the sleeve sleeves the drill bit; a limiting piece is arranged on the sleeve and / or the transmission shaft and can limit the movement of the transmission shaft close to the sleeve. The psammophyte cultivation device can effectively improve the technical fortress and defects in the planting process of quicksand environment protection forests in the northwest arid region, and has the following advantages that the nursery stock planting process is mechanized and standardized; compared with traditional planting ideas relying on natural precipitation, it is firstly proposed that the moisture stored in wet sand layers at the deep positions of sand dunes is utilized to increase continuous moisture supply for plants so that the planting process can be operated all the time; according to different local wet sand layer depths and planting species, the specification of plant planting pits can be adjusted by replacing the specification of the nested vertical spiral drill bit.

Description

technical field [0001] The present invention relates to the field of psammophyte cultivation, in particular to a psammophyte cultivation device and method. Background technique [0002] Among the many ecological improvement measures, the afforestation measures of "right tree for the right place" have received extensive attention and application. However, limited by the local natural environment and ecological factors, afforestation is difficult to fully implement and promote. In some areas, it even causes the embarrassing phenomenon of "no trees are planted every year, no forests are planted every year", especially on the surface of quicksand . And the main reason that causes above-mentioned phenomenon has following: the one, the irrationality of train of thought of quicksand surface nursery stock planting. The traditional planting idea is to plant seedlings directly after excavating the dry sand layer manually, and the root system of the plant will not have access to effe...

AI Technical Summary

Problems solved by technology

The traditional planting idea is to plant the seedlings directly after excavating the dry sand layer manually. The root system of the plants will not have access to effective water, which will cause the plants to die due to lack of water in the early stage of growth.

In areas with good traffic and water source conditions, artificial irrigation measures can be assisted to meet the water demand for early survival of seedlings. However, due to the uncertainty of irrigation intervals and insufficient water volume, coupled with strong evaporation on the surface of quicksand and rapid infiltration of water, eventually resulting in plant damage. low survival rate

Second, the planting methods and techniques are not perfect enough

During the manual excavation process, due to lack of protective measures, a large amount of loose quicksand slipped down, and the tree pits that were originally excavated into the wet sand layer were buried, which not only took a lot of work and labor, but also affected the survival rate of plants

The third is that the traditional artificial planting technology has fallen far behind the pace of "national ecological construction", and its efficiency is low, making it difficult to realize mechanized operations

Coupled with the blind pursuit of engineering progress and economic benefits, the planting depth of seedlings is not enough, so that the plants that were originally designed to touch the wet sand layer in the sand area cannot touch the wet sand layer, resulting in the death of plants due to lack of water

In view of this, a vegetation cultivation device suitable for quicksand surfaces in sandy areas was developed to realize mechanized and standardized construction, and make full use of the moisture in the wet sand layer of dunes to solve the low survival rate of plants caused by the inability to obtain continuous water supply. It can avoid the death of plants caused by unreasonable artificial cultivation methods, which is of great significance for improving the ecological environment of sandy areas
