Problems solved by technology

However, due to the very limited number of fruiting plants of sandalwood and red sandalwood in my country, India, the country of origin, prohibits the export of sandalwood and red sandalwood seeds, and it usually takes more than 15 years for the seedlings of sandalwood and red sandalwood to become fruitful after planting, so there is a serious shortage of sandalwood in the seedling market. Fragrant rosewood seeds
This kind of situation has seriously restricted the development of my country's sandalwood and red sandalwood planting industry.

Embodiment 1

[0044] (1) Preparation and processing of rootstock

[0045]In February 2009, truncated Indian red sandalwood plants with a DBH of 20cm to 28cm, and kept the trunk height at 2.0 to 2.5m. A total of 30 plants were treated. After 20 to 30 days, depending on the growth of the shoots, the buds were wiped and the plants were established, and 5 to 10 thick shoots with a diameter of 1.5cm to 4.5cm were reserved for each tree as rootstocks.

[0046] (2) Collection of scion branches

[0047] In March, cut well-growing branches with full axillary buds from the middle and upper part of the canopy of the 25-year-old strong sandalwood red sandalwood tree, quickly cut off the leaves, wrap them in wet towels or fresh banana leaves to keep them moist, and transport them to the place where the rootstocks are placed as scion branches.

[0048] (3) Scion treatment

[0049] Cut the above-mentioned scion branches into branches with 2 to 5 buds as the scion; cut out a bevel with an inclination ang...

Embodiment 2

[0061] (1) Rootstock preparation:

[0062] In March 2009, the Indian red sandalwood saplings with a diameter of breast height of 2.0-5.0 cm were directly truncated as rootstocks, and the trunks were kept 1.0-1.5 m high. A total of 30 plants were treated.

[0063] (2) Collection of scion branches

[0064] In March, cut well-growing branches with full buds from the middle and upper part of the canopy of a 25-year-old strong sandalwood red sandalwood tree, quickly cut off the leaves, wrap them with wet towels or fresh banana leaves to keep them moist, and transport them to the place where the rootstocks are placed as scion branches.

[0065] (3) The steps of scion treatment, rootstock treatment, grafting operation and post-grafting management are the same as in Example 1.

[0066] (4) Water and fertilizer management of grafted plants

[0067] Water regularly according to the weather conditions. After the joints are completely healed and new shoots are drawn out from the scion,...

Abstract

The invention discloses a grafting method for promoting early fruiting of pterocarpus santalinus. The pterocarpus santalinus is grafted onto a pterocarpus indicus plant, growing development and early fruiting of the pterocarpus santalinus are promoted by the aid of the characteristics of high water and fertilizer absorption capacity and rapid growth of pterocarpus indicus, so that the situation of pterocarpus santalinus seed shortage is rapidly relieved, and the ever-increasing active demand of China for pterocarpus santalinus seeds and seedlings is met. By the grafting method, growth of the pterocarpus santalinus can be accelerated, and the initial fruiting period of the pterocarpus santalinus is remarkably shortened.

Description
