Abstract

The invention discloses a method for promoting the decomposition of understory litter of tropical Casuarina equisetifolia coastal defense forest, comprising the following steps: A: selecting seeds of A. chinensis, A. japonica and A. japonicus; B. The seeds of sterilization, seed soaking, and seed preparation are carried out; C, the seeds of step B gained a little red, Flos japonica and Toxocarpus are sown under the Casuarina forest, and watered and fertilized in the later stage. The method can promote the decomposition of understory litter in the casuarina coastal protection forest and increase the plant diversity of the understory of casuarina.

Description

technical field [0001] The invention relates to the field of plant science and technology, in particular to a method for promoting the decomposition of understory litter of tropical Casuarina officinalis forest. Background technique [0002] Casuarina, also known as the horsehair tree and the casuarina tree, is an evergreen tree of the dicotyledonous class Casuarinae family. damp. Due to its rapid growth, strong wind resistance, and no fear of sand burial, Casuarina has quickly become an excellent tree species for windbreak and sand fixation in the coastal areas of southern China. However, the tropical coastal coastal defense forests in Hainan are pure casuarina forests, with a single tree species, the same age, and a simple structure. The litter and other litter under the forest are also consistent in the properties of the litter layer, and the soil fertility is poor. cycle. In addition, the understory is often covered with thick litter layers, the composition of the un...
