本文报道了石梓栽培技术研究结果:23°N以南为石梓适生地区,其年均温20.5～24.5℃,极端低温>-1.5℃,年降雨量1200～2000mm,年平均风速<2.5m/s。适宜立地为地形开阔,阳光充足,土壤疏松,表土层含有机质>2%,全氮>0.1%,速效磷>0.25mg/100g土,pH 4.5～6.9,土壤含水率10%～24%。种子贮存以干燥器最好,贮存一年发芽率87.4%。催芽用浸晒和浸沤处理,比不处理提前10天发芽,发芽率提高9%～12%;不同子叶类型的芽苗分别移植,较混合移植的苗木合格率提高20.6%;评定了种子主要质量指标和效果良好的育苗、造林方法。技术综合指标:材积年均生长量>12m~3/ha。
The results showed that the average annual temperature was 20.5-24.5 ℃, the extreme low temperature was -1.5 ℃, the annual rainfall was 1200-2000 mm, the annual average wind speed was less than 2.5 m / s. Suitable site for the terrain open, sunny, loose soil, surface soil organic matter> 2%, total nitrogen> 0.1%, available phosphorus> 0.25mg / 100g soil, pH 4.5 ~ 6.9, soil moisture content of 10% to 24%. Seed storage to the best dryer, one year storage rate of 87.4% germination. Germination with immersion and immersion treatment than the non-treatment of germination 10 days earlier, the germination rate increased 9% to 12%; different cotyledon types of sprouts were transplanted, compared with mixed transplanting seedlings pass rate increased by 20.6%; assessment of the main seed Quality indicators and effective nursery, afforestation methods. Technology Composite Index: Volume annual growth> 12m ~ 3 / ha.
