Pear so expensive, why not plant it in rural areas?
I answer this question from a botanical point of view it.
First, what is pear
Pear wood is actually a trade name, its official Chinese plant called rosewood, alias there Dalbergia, rosewood sandalwood, pear mother, is a leguminous plant Dalbergia scientific name Dalbergla odorifera T. chen. The name comes from mother pear pear, pear is a name for the parent of Hainan. It's only wild in central and southern Hainan, often grow sparse forests or open ground on the hillside.
Is a pear tree, ten to fifteen meters height, plant glabrous, bark brown, rough, vertical lines. Pinnate three to six pairs of leaflets have, ovate or elliptical leaves, close leathery. Panicle length of about ten centimeters, Butterfly-shaped, white or pale yellow.
Tongue-shaped pods, oblong, one or two seed.
Second, the growth of pear status quo
Wild pear tree only in Hainan, in recent years, Guangdong, Fujian, Guangxi, Yunnan and other provinces introduction and cultivation, in some places has been the establishment of plantations, not without cultivation. Since the start of the study pear relatively late, the study also small, so in terms of seedling breeding, introduction and domestication and cultivation technology is not very mature.
Third, the growth characteristics of pear
Pear often grown in a medium altitude of sparse forest, open ground, and now the technology can Varieties in place only in some tropical and subtropical regions, other parts not used to; it is loving plant growth optimum temperature twenty to thirty between ten degrees, greater than 1000 mm in claim precipitation, temperature, Low, so that environmental conditions do not have other places, so enough large-scale cultivation in rural areas elsewhere. It's slow growth, the finished product takes a long time.
Fourth, the value of pear
First, it is fine wood furniture timber, pale yellow sapwood, heartwood reddish-brown, hard heavy material, delicate texture, looks very beautiful. High economic value in the market is one of the few pounds and make money with timber, according to information about four thousand yuan per kilogram.
Second, it's the root of heartwood called rosewood, can be medicinal, we have a good analgesic effect, but also the treatment of bleeding wounds. Consult with doctors when medicinal.
Third, pear slow-growing, dense foliage, high economic value, in some places around Hainan and introduction of multi-species for landscaping now.
In short, despite the pear is very expensive, not because of large-scale cultivation in the more rural areas, mainly its growth characteristics, other places do not adapt, grow slowly addition, see the benefits take a long time.
