Transformation method of island eucalyptus forest

Abstract

The invention provides a transformation method of an island eucalyptus forest. According to the method, restoration species suitable for islands are screened out: liquidambar formosana hance, celtis sinensis, acacia confuse, schefflera octophylla, bauhinia purpurea, acacia podalyriifolia, codiaeum variegatum, and pandanus tectorius, furrows are made in the middle of the row of 9-12 years old island artificial eucalyptus trees with a plant spacing of 3-4 m and a row spacing of 2-3 m, 1-2 years old seedlings of the restoration species are transplanted into the furrows, nutrient soil is added tohelp the seedlings perform field planting quickly, and each seedling is watered 2-3 times a week and 3-5 L once for management and maintenance. The survival rate of each restoration species planted bythe method in the island eucalyptus forest is higher than 80%. By modifying the eucalyptus forest, the quality of island vegetation can be improved, biodiversity is increased, and ecological problemscaused by planting eucalyptus on a large area are reduced. In addition, the eucalyptus forest transformation scheme provided by the invention has good stability, and can achieve improved effects on many batches of eucalyptus forests.

Description

technical field [0001] The invention relates to the field of sea island planting, in particular to a method for transforming a sea island eucalyptus forest. Background technique [0002] Eucalyptus (Eucalyptus) is the general name of Eucalyptus in Myrtaceae. It has strong adaptability, rapid growth and wide application. It is the main fast-growing and high-yielding exotic tree species in southern my country. However, the large-scale planting of eucalyptus has also caused a series of ecological problems, such as soil degradation, soil erosion, nutrient cycle imbalance in plantation forest ecosystems, occurrence of diseases and insect pests, and reduction of biodiversity, which seriously affect the sustainable management and development of eucalyptus forests. Sustainable use of forest land. Eucalyptus not only has a strong ability to compete for water and fertilizer, but also has a strong allelopathic effect, which will release certain chemical substances to inhibit the growt...

AI Technical Summary

Problems solved by technology

Due to the stress of these environmental factors, the habitat of the island is very fragile, and the habitat is easily destroyed, and once destroyed, it will be difficult to restore. In addition, the allelopathy of eucalyptus itself to other species leads to the transformation of eucalyptus forests on islands. It is relatively difficult, and there are no relevant research reports on the transformation of eucalyptus forests on islands

Large-scale pure eucalyptus forests on islands lead to many ecological and environmental problems such as single species of biological communities, simple ecological structure, poor stability, vulnerability to pests and diseases, decline in water and soil conservation, serious soil erosion, and decline in biodiversity.

Due to the particularity and complexity of the island habitat, the transformation technology of eucalyptus forests on land is no longer suitable for the transformation of eucalyptus forests on islands, and it is more difficult to transform them on islands
