Abstract

The invention discloses a method for promoting decomposition of litters under a tropical casuarina equisetifolia coastal protection forest. The method comprises the following steps: A, selecting seeds of emilia sonchifolia, borreria stricta and cyrtococcum patens; B, disinfecting, soaking and preparing the seeds of the emilia sonchifolia, the borreria stricta and the cyrtococcum patens; and C, sowing the seeds of the emilia sonchifolia, the borreria stricta and the cyrtococcum patens obtained in the step B under the casuarina equisetifolia forest, and carrying out watering and fertilizing in the later period. The method can promote decomposition of the litters under the casuarina equisetifolia coastal protection forest and increase diversity of plants under the casuarina equisetifolia forest.

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 in tropical casuarina and sea defense forests. Background technique [0002] Casuarina, also known as Mamao tree and Bone tree, is an evergreen tree of the genus Casuarinaceae in the dicotyledonous plant class Casuarinaaceae; Casuarina likes light, likes hot climates, likes calcium and magnesium, is tolerant to salt and alkali, poor soil, and drought-resistant wet. Due to its rapid growth, strong wind resistance, and no fear of sand burial, casuarina has quickly become an excellent tree species for wind and sand fixation in the coastal areas of southern China. However, the tropical coastal defense forests in Hainan are all pure casuarina forests, with single tree species, uniform forest age, and simple structure. Litters such as litter in the undergrowth are also relatively consistent in nature and soil fe...
