Problems solved by technology

For example, young seedlings have not been considered in the research category of agarwood industry development, and the advantages of biological resources such as many seeds, simple seedling cultivation, and rapid growth cannot be fully exploited. Moreover, the current artificial agarwood focuses on a single category of "resin-containing wood". Paying full attention to a number of agarwood items summarized by the experience of the ancients, such as the realization of "green osmanthus" and other agarwood, will further enrich the content of agarwood industry development

Abstract

The invention discloses a water-absorbing controlled-release film for agilawood formation. The water-absorbing controlled-release film is mainly prepared from the following raw materials in parts by mass: 10-30 parts of a water-absorbing polymer material, 5-10 parts of an agilawood inducer nano controlled-release microspheres, 40-60 parts of a base film, 0.5-4 parts of plant nutrients, 0.1-1 partof organic acid and 400-1000 parts of water. The moisture-absorbing controlled-release film coats an aquilaria sinensis trunk, can realize long-acting controlled release of an agilawood formation inducing substance, is beneficial to production of bark oil by bark agilawood , and is also beneficial to formation of resin-containing wood, so that the yield and quality of agilawood are improved.

Description

technical field [0001] The invention belongs to the technical field of agarwood, and in particular relates to a water-absorbing controlled-release film for agarwood and a method for producing agarwood. Background technique [0002] Agarwood is a precious spice and traditional medicinal material in China, Japan, India and Southeast Asian countries. At present, the wild resources are exhausted and endangered. [0003] Aquilaria sinensis (Lour.) Gilg, also known as Aquilaria sinensis (Lour.) Gilg, is a plant of the genus Aquilaria in the family Daphneaceae. It is the only genuine original species of agarwood in China. Domestic agarwood is a wood block containing resin that condenses near the wound of white wood after being injured by the outside world. It usually takes several years to form. The natural output rate is extremely low, and its wild resources are also exhausted and endangered. Artificial planting and artificial incense are the correct direction for the sustainable...
