Example Embodiment

[0026] Embodiment one: if figure 1 and figure 2 , a kind of planting method that promotes the rapid growth of sandalwood with heterogeneous interbreeding, comprises the following steps:

[0027] (1) Selection and clearing of afforestation land: In Banqiao Town, Dongfang City, Hainan Province, select a gentle slope land with fertile and loose soil, sunny terrain, good drainage and shelter from wind (or with wind-proof conditions), clean up vicious miscellaneous irrigation, and keep benign miscellaneous fields such as Tianqing. fill;

[0028] (2) Planting host plants: In the spring of 2014, plant 1-year-old (ground diameter 0.8-1.2cm, tree height 0.8-1.2m) sandalwood red sandalwood container seedlings, planting hole specifications: 50cm×50cm×40cm, plant row spacing 3m× 6m, put 10kg of retting farmyard manure and 500g of superphosphate in each planting hole and mix them as base fertilizer;

[0029] (3) Colonization of sandalwood: in the spring of 2016, 2 years after the plant...

Example Embodiment

[0032] Embodiment two: the difference with embodiment one is that embodiment two selects to plant sandalwood at the same time of planting sandalwood red sandalwood container seedling. When 6 years old, 100 sandalwood trees were randomly selected for investigation, and their growth is shown in Table 1. It is obvious that the growth of sandalwood planted by different-age mixed methods is better.

Example

[0035] Comparative examples one to two: the difference with embodiment one is that comparative example one adopts Dalbergia dalbergia to carry out mixed planting as host plant and sandalwood at the same time ( image 3 ); Comparative example two adopts Akiras sinensis as host plant and sandalwood to carry out mixed planting at the same time ( Figure 4 ). When 6 years old, 100 sandalwood and host plants were randomly selected for investigation, and their growth conditions are shown in Table 2.

[0037]

[0038] Adopting a planting method of the present invention to promote the rapid growth of sandalwood by mixed crossing of different ages, by first planting sandalwood and red sandalwood, and then colonizing sandalwood after 2 years, the mixed crossing of sandalwood and sandalwood and red sandalwood is formed in this way. Not only the narrow canop...

Abstract

The invention discloses a planting method for promoting rapid growth of Santalum album through different-age mixed crossing, which comprises the following steps of: planting annual pterocarpus santalinus container seedlings with the row spacing of 3m * 6m; after the pterocarpus santalinus grows for 2 years, digging holes in the middles of every four adjacent pterocarpus santalinus, field-plantingof one-year-old Santalum album container seedlings, the mixing ratio of the Santalum album to the pterocarpus santalinus is 1: 1, and the planting spacing is 3m * 3m; within 3-5 years after pterocarpus santalinus is planted, cleaning malignant miscellaneous shrubs, and reserving benign miscellaneous shrubs, so that Santalum album hosts are increased. According to the method, different ages are mixed, the narrow crown of the pterocarpus santalinus is utilized, and the proper plant spacing is matched, so that the Santalum album is self-supplied with nutrition through photosynthesis; the strong penetrating power of the root system of the pterocarpus santalinus is utilized, and benign miscellaneous shrubs are reserved during tending, so that the Santalum album sucker can be quickly fixed in the thicker root system of the pterocarpus santalinus and the benign miscellaneous shrubs to fully absorb nutrients and moisture, and finally a stable pterocarpus santalinus and Santalum album mixed community is quickly formed to promote quick high-quality growth of Santalum album.

Description

technical field [0001] The invention relates to the technical field of planting precious forest trees, in particular to a planting method for promoting the rapid growth of sandalwood by mixing different ages. Background technique [0002] Sandalwood (Santalum album L.) is a semi-parasitic evergreen small tree, which is naturally distributed in Indonesia, and has been introduced and cultivated on a large scale in countries such as India and Australia. Sandalwood is a precious timber tree species. It is a good raw material for the production of exquisite handicrafts, essential oils and fragrances, and important traditional Chinese medicines. It has high medicinal and economic value. Due to the high economic value of sandalwood, its wild resources have been plundered for a long time and have been exhausted. The main producing countries of sandalwood have gradually restricted the export of sandalwood. Therefore, only by self-reliance to develop the sandalwood planting industry ...
