Problems solved by technology

As an important and precious economic tree species, Fiji sandalwood is very popular. However, due to the limited number of fruiting plants of Fiji sandalwood introduced in my country, the country of origin prohibits the export of seeds, and the asexual propagation technology of sandalwood is very difficult. Therefore, there is a serious shortage of Fiji sandalwood seedlings in the seedling market. This situation seriously restricts the development of my country's Fiji sandalwood planting industry.

Abstract

The invention belongs to the nursery stock breeding field, and specifically relates to a Fiji sandalwood different-stock grafting seedling method; the stock-scion two-side grafting method is employed so as to graft the Fiji sandalwood on an Indian sandalwood plant; Indian sandalwood is rich in planting resources in south china regions, fast in growth speed, strong in adaptability, early in heartwood formation time, and high in heartwood essential oil content; the advantages of the Indian sandalwood can be utilized so as to enable the Fiji sandalwood to fast grow in our nation, thus alleviating the problems that Fiji sandalwood in low in maturing rate in our nation or has zero maturating rate, and seedling is rare; the novel method can satisfy growing demands for the Fiji sandalwood seedlings in our nation, can greatly improve seedling survival rate, and obviously adding quality nursery stock supply.
