Description

Leaf-free false horsetail seedling auxiliary updating method

Technical Field

The invention relates to the technical field of forestry, in particular to an auxiliary updating method for leaves-free false horsetail seedlings.

Background

The leafless false horsetail (anabaslla) belongs to anabasine (Chenopodiaceae) of anabasine (Anabasis) of Chenopodiaceae, has the height of about 60cm, is mainly distributed in Sinkiang and Gansu, is often grown in salinized arid deserts such as a mountain-front Hongma fan, a low land between hills, an arid low mountain slope and the like, has a deeper underground water level of a habitat, is arid and compact in soil, is normally light and moderately salinized, is a building species of the soil deserts, and has unique ecological characteristics. The stanilla lasiocarpa plays an important role in saline-alkali soil and cracked land transformation and wind prevention and sand fixation in the desert area, and has certain significance in maintaining the water and soil safety of the mountain forward flood fan. In addition, the fig can be an important medicinal plant resource and has a good application prospect in the subsequent industrial development of the returned forests.

The quasi-Saonor basin belongs to a typical temperate zone continental climate area, and has drought and little rain, the precipitation is below 150mm, and the evaporation capacity is 10-100 times of the precipitation; the extreme maximum temperature is above 40 ℃, and the extreme minimum temperature is below-40 ℃. The habitat of the area is severe, species are poor, vegetation is sparse and short, and in addition, artificial development is improper, so that the habitat is further worsened, and seedlings of most plants are difficult to naturally update. Rainfall in the quasi-songer basin in winter is stored on the ground surface in the form of snow, and when the temperature rises gradually and the snow is melted in early spring, water source supply is provided for seed germination, and a favorable environment foundation is provided for plant propagation; in particular the depth of the snow and the time to thaw determine many ecological processes of the communities and ecosystems. However, global warming causes the duration of the spring climate in the desert region of the similar sooner rocky region to be extremely shortened, and the dry and hot climate in summer of the desert appears in advance, and although the process has volatility, the shallow soil of the desert is also caused to be rapidly dried, so that the sprouting of the spring sprouting plants is rapidly dead, which is a common phenomenon appearing in recent desert vegetation.

Detailed Description

The invention provides a leaf-free false horsetail seedling auxiliary updating method, which comprises the following steps:

In the invention, the step of forming the ditch comprises the step of digging the ditch on the ground where the leaves-free false horsetail seedlings are located, the seedlings grow in the ditch, and the snow melting water and the rainwater can flow into the ditch and collect at the roots of the seedlings.

In the invention, a sand layer is formed by covering sandy soil on the opened ditch, and the thickness of the sand layer is preferably 3-5 mm; the sand layer can slow down the water evaporation of the shallow soil layer, thereby being beneficial to the survival of the true sepia seedling, so that the supplement of the local true sepia seedling can still be maintained, and even the population structure of the true sepia seedling shows the growth trend.

In the invention, the components adopted by the drip irrigation comprise a primary branch pipe and a capillary pipe, and a drip irrigation emitter is arranged on the capillary pipe.
