Embodiment 1

[0023] Embodiment 1: Cultivate multi-standard Pond firs on land and carry out large seedling cultivation in root-controlling containers for two years to complete land growth. During the period when the water level of the reservoir is the lowest in February, the selected area is 0.45hm 2 In the alluvial soil water-fluctuation zone of the gentle slope, dig the planting hole and plant directly to complete the water length. Specifically, plant Pondus fir with a row spacing of 4m×4m on the slope, and transplant large seedlings with soil balls in root-controlling containers. Plant in sequence toward the water level low line 3. After the pond fir is positioned in the planting hole, the periphery of the root is fully tightened, and the local surface is covered with concrete with a thickness of 3 cm, and the seedling support is arranged (the support can be removed after one year). According to the survey results in the 21st year after planting, the average tree height is 12.5m, the a...

Embodiment 2

[0024] Embodiment two, during the period when the reservoir water level is the lowest in February, select an area of ​​0.2 hm 2 The weathered bedrock gently slopes in the low-fluctuation zone. The soil on the slope zone has suffered from water and soil erosion over the years, and the soil erosion is serious. The C layer of the soil is exposed, and the vegetation basically disappears. First use a root-controlling container 7 with a diameter of 50 cm and a height of 50 cm on land, select pond fir, bald cedar, metasequoia, and maple poplar for terrestrial growth, and cultivate them into a height of 4.5 to 5 m and a breast diameter of 4 to 4.5 cm. Planting holes, the lowest part of the planting holes is level with the low water level line 3, the seedlings together with the root control container 7 are planted on the fading zone according to the horizontal gradient, the top of the root control container 7 is provided with a closing mouth, and a week of the closing part is provided w...

Abstract

The invention relates to a weathered bedrock hydro-fluctuation belt land seedling cultivation and water growth tree planting method. Because of seasonal water level rise and fall, the weathered bedrock area of the submerged land around a reservoir area exposes periodically, and the method is used for permanently greening the weathered bedrock area by planting trees. The method is characterized in that according to the rise and fall gradient of the water level, root-control container seedlings with corresponding sizes are cultivated on the land, so that land cultivation is completed, then, planting holes are dug on the weathered bedrock hydro-fluctuation belt, planting is directly carried out, and water growth is completed. With any water level, planted water-tolerant hygrophilous trees can partially expose out of the water surface, the photosynthesis and respiration of seedlings can be guaranteed, the phenomenon that soil at the roots of trees is washed out year after year is prevented, the growth of the trees is stabilized, the species of diversity is enriched, and the strong slope protection and soil fixation effects are achieved.

Description

technical field [0001] The invention relates to forestry ecological system technology, in particular to a method for planting trees in terrestrial water-growing zones in weathered bedrock water-fluctuating zones. Background technique [0002] Water-Level-Fluctuating Zone refers to a special area where the water level fluctuates seasonally and the surrounding submerged land periodically emerges from the water surface. Generally, there is such a Fluctuating Zone around the reservoir. The water-fluctuating zone is a transitional zone controlled alternately by aquatic ecosystems and terrestrial ecosystems, with various types. Different types of water-fluctuating zones are affected by factors such as hydrology, climate, landform, and human activities, which will have an important impact on the evolution of the water-fluctuating zone. In the area of ​​soft and accumulated soil, not only the natural vegetation has been stripped away, but also constantly affected by the fluctuation...
