| 摘 要： | 测定分析了10种国外产竹种子的形态特征，并对他们进行育苗试验。结果表明：种子形状多为卵形、长锥形、椭球形，颜色以黄褐色、褐色、褐黑色为主，长度和直径分别为4~60 mm和0.9~5.5 mm；果实一般为圆锥形、锥形、卵形，颜色以灰褐色、灰色为主，长度和直径分别为5~64 mm和1.2~7.5 mm；大藤竹种子播种品质指标最好，具有最高的纯净度（97.4%）、千粒质量（201.0 g）、发芽率（95.4%）、发芽势（51.5%）、含水量（9.3%）、生活力（98.8%）及较低的病虫害感染度（6.5%）；有机质是有效提高各竹种出苗率的首选基质；宜采用先撒播种子，待胚苗有1~3片叶时再移入营养袋培育的育苗方式；育苗时施用氮磷钾复合肥，并在苗木离地50 cm处进行封顶处理，能有效促进苗木生长。

| Abstract: | The morphological characteristics of 10 species of foreign bamboo seeds are measured and the seedling experiments carried out. The results show that most of the bamboo seeds are oval, cone-shaped and ellipsoid in shape, and mainly yellow brown, brown and brown black in color, and their length and diameter are 4~60 mm and 0.9~5.5 mm, respectively. Their fruits are generally cone-shaped, cone-shaped and oval-shaped, mainly gray brown and gray in color and with length and diameter of 5~64 mm and 1.2~7.5 mm. Dinochloa marginata has the best sowing quality in purity (97.4%), thousand-grain weight (201.0 g), germination rate (95.4%), germination potential (51.5%), water content (9.3%), vigor (98.8%) and infection rate of diseases and pests (6.5%). Organic matter is the best seedling substrate for effectively improving the emergence rate of all species of bamboos; the way of seedling cultivation is to sow seeds first, and then transplanting the embryo seedlings into the nutrition bag when they has 1~3 leaves; the application of nitrogen, phosphorus and potassium compound fertilizer and the sealing at the seedling height of 50 cm can effectively promote the growth of seedlings. |
