橡子是我国的一项重要野生植物资源,根据分析,一般风干橡仁的淀粉含量为55—60％,并且还含有蛋白质和脂肪。可用于酿酒,制酒精,制糕点,做豆腐和当饲料。橡子的外壳称为橡碗,可制烤胶、活性炭、糠醛、染料和燃料等。我国的橡子资源丰富,有分布在大小兴安岭和长白山的辽东栋、蒙古栎、懈树;有分布在秦岭、大巴山、大别山的拴皮栋、麻栎和分布在南岭、五岭等地的拷槠类等。橡子树由于耐干早、耐瘠薄、萌发力强和种子容易繁殖,在我国大部分山区、半山区都有分布。部分橡子树,如栓皮栋、栲树等,开花后当年只形成小幼果就停止发育,第二年才发育成熟。而有些橡子树,如蒙古栎、辽东栎、檞树等是当年开花结果,当年成熟。橡子的成熟期也因树种和地区不同而不一样。东北地区的橡子,一般成熟较早,8月下
Acorn is an important wild plant resource in China. According to the analysis, the starch content of dried air is generally 55-60%, and also contains protein and fat. Can be used for wine making, alcohol, cakes, tofu and when the feed. Acorn shell called rubber bowls, can be baked plastic, activated carbon, furfural, dyes and fuels. There are abundant acorn in our country. There are Liaodong Dong, Quercus mongolica and Lost tree located in Xinganling Mountains and Changbai Mountains. There are shingles, Quercus acutissima and Quercus variabilis distributed in Qinling Mountains, Daba Mountains and Dabie Mountains. Khao 槠 classes and so on. Acorn tree due to early drying, resistance to infertility, germination and seed easy to breed, most of our mountainous area, Mid-Levels have distribution. Part of the acorn tree, such as corkscrew, Sui tree, after flowering, only the formation of young and jujube stopped development, the second year before maturity. Some acorn trees, such as Mongolia oak, Quercus liaotungensis, Sassafras tree is the flowering year, then ripe. The maturity of acorns is also different for different species and regions. Acorn in northeast China, generally mature earlier, in August
