Figure 20. A) Out looking view and B) inner view of a Pinus armandii forest, Mt. Alishan, Taiwan (photo by Mr. Liao). No natural hybrids are known to exist but P. armandii has been successfully crossed with P. lambertiana (Duffield and Righter, 1953) SITE REQUIREMENTS Pinus armandii requires much milder climate than P. koraiensis. The habitat in the mainland of China has quite a mild winter and averages over 200 days of frost-free growing season. Annual precipitation ranges from 500 mm in the northwest (Kansu) to 1,100 mm in the south (Yunnan) with a peak rainy period in June and July (Fig. 21). It appears that the major part of the natural range belongs to a semi-arid climate type. Temperature data for the Chinese mainland and Formosa habitats are given in Fig. 22. The soils over the natural range of Pinus armandii on the Chinese mainland are derived from limestone in many cases, but some are derived from shale, slate, and sandstone (Szechwan and Yunnan). Neutral to alkaline soils are commonly found in arable flat lands, although in high elevations in Kansu and Shensi, degraded Chestnut-soils and Chernozems are developed. In Szechwan a brown forest soil type is developed on the shale, slate, or sandsone. Elsewhere, with more rain, podsolization has progressed to form red and yellow podzolic soils and some Rendzina type soils (Mima and Kato, 1938)..
