Description

A kind of santal industrialization kind woodlot

Technical field:

The present invention relates to the santal field of planting, be specifically related to a kind of santal industrialization kind woodlot.

Background technology:

Santal (Santalum album) is that the Santalaceae santal belongs to evergreen dungarunga, and its heartwood can be extracted essential oil, is a kind of good fixastive, also is preparation highclass perfumes and the indispensable base stock of essence; Its heartwood quality is solid, texture is fine and close evenly, is the excellent material of making hand work product and woodcut; Sandalwood oil and sandalwood are pharmaceutically also having been widely used, and its medical value is with a long history, so santal is one of the most expensive in the world timber.

Santal is a kind of partial parasite, originate in the ground such as India, Indonesia and Australia, its growth is extremely slow, usually wants many decades just can become a useful person, one of the slowest seeds that grow, simultaneously, almug is very enervated, also must colonize at Seedling Stage on the plants such as Ormosia hosiei just can survive, Gu and the output of santal is very restricted, people are very large again to its demand, so from ancient times to the present, it always is i.e. expensive again rare timber.

In recent years, be subjected to the stimulation in international santal market and the impact that regional economic structure adjusts, santal plantation integral body is rapid growth situation, cultivated area is increasing, enterprise and the specialist of plantation santal are more and more, and the industrialization cultivation is arranged on the ground such as Guangdong, Guangxi, Yunnan and Hainan in south China area.

Although it is high economic crops of unit are income second in the world that many enterprises and crop cultivation speciality family have realized that santal, but most enterprises and crop cultivation speciality family are to the propagation technique of santal, the shortage such as culture technique and maintenance technology system, comprehensively, the understanding of science, especially select problem by general ignorance and simplification as the forest land of santal industrialized development bottleneck problem, as santal being planted in farmland planting ground, not only the growth of the santal of plantation is slow, cycle is long, and growing way is poor, the poor effect of becoming a useful person, directly affect investor's investment repayment, simultaneously, the improper land resources waste that causes preciousness that the forest land is selected, give the individual, enterprise and country all bring certain negative effect, therefore, the selection problem that solves santal industrialization kind woodlot is not only a technical problem, and is an important social concern.

Summary of the invention:

The purpose of this invention is to provide a kind of santal industrialization kind woodlot, this santal industrialization kind woodlot plantation santal seedling, santal seedling establishment survival rate height, fast growth, growing way are evenly neat, simultaneously, the Edgeworthia chrysantha rate is high, heartwood is fine quality, is suitable for the extensive industrialization plantation of santal.

Santal industrialization kind woodlot of the present invention is characterized in that, the land occupation condition of this santal industrialization kind woodlot is:

A, amblent air temperature: planting site must winter without snow and serious frostbite, extreme temperature is not less than-3 ~ 0 ℃, daily mean temperature reaches 6000 ~ 8000 ℃ greater than 10 ~ 15 ℃ accumulated temperature, annual rainfall is at 600 ~ 2000mm;

B, features of terrain: the positive hillside fields of planting site or the foot of a mountain, farmland, the level land of spaciousness and low-lying planting site should not be planted;

C, soil index: the soil of planting site with the sandy red loam that is rich in the nutritive elements such as iron, phosphorus, potassium, pH value between 5 ~ 6, forest land soil depth 50 ~ 150cm;

D, moisture situation: planting site is avoided ponding, groundwater level 80 ~ 120cm with interior or rainy season may ponding the place all should not plant.

The present invention santal industrialization kind woodlot preferred aspect, start with from amblent air temperature, features of terrain, soil index and moisture situation etc. emphatically, analysis-by-synthesis, consider comprehensively, preferably plant woodlot and create conditions for the health that promotes santal industrialization plantation, stable, benign development, on this santal industrialization kind woodlot, santal seedling establishment survival rate height, fast growth, growing way are evenly neat, simultaneously, the Edgeworthia chrysantha rate is high, heartwood is fine quality, is suitable for the extensive industrialization plantation of santal.
