植树造林是我们中华民族的传统美德,我们勤劳勇敢的祖先对此早就十分重视。早在公元前1000多年西周时期,国家就设立了“林衡”、“山虞”等官职。甚至明文规定“不树者,无椁”即不种树的人死后连薄皮棺材都没有。在《诗经》中也大量提到树,以树喻人,以树喻情,赞扬种树的美德,讽刺鞭挞毁树的可耻,如《诗经·魏风;伐檀》就以辛辣的笔锋鞭笞了毁树造车的可耻行径。 公元166年,东汉崔寰著的《四民月令》主要阐述了种植蚕桑、蔬果、树木等的性别差异和繁育种植。这是我国一部有关植树造林和繁殖育种的理论专著。 到了公元185年,北魏孝文帝时不仅要求植树,连品种数量都有具体规定;“男夫一人,给田二十亩,课莳余,种桑五十树,枣五殊、榆三根……限三年种毕,不毕,夺其不毕之地。”北魏贾思勰的《齐民要术》概括了当 Tree planting and afforestation is the traditional virtue of our Chinese nation.
