树叶利用已引起世界许多国家的重视。目前树叶的利用主要是做家畜、家禽配合饲料中营养补充物或饲料的添加物,每吨气干树叶约可代替一吨谷物~([1]),这对于粮食和蛋白质短缺的地区是值得重视的,苏联匈牙利在这方面已有工业生产,匈牙利生产的产品除供应本国外,还有部分出口。树叶中除含有蛋白质外,还含有脂肪、糖类、维生素、叶绿素、胡萝卜素、激素、精油等,又可以作为医药及粘胶剂的填充剂等轻化工制品的原材料。有些成份含量虽少,但具有特殊经济价值。因此,开展树叶利用的研究具有重要的意义。
The use of leaves has drawn the attention of many countries in the world. At present, the utilization of leaves is mainly to supplement nutritional supplements or feedstuffs in livestock and poultry feedstuffs, and about one tonne of dry leaves per ton of grain can substitute for one tonne of grain ([1]), which is worthwhile for food and protein deficient areas It is important to note that the Soviet Union and Hungary have already produced industrial products in this area. The Hungarian-produced products, besides their own supplies, have also been partially exported. In addition to the leaves contain protein, but also contains fat, carbohydrates, vitamins, chlorophyll, carotene, hormones, essential oils, but also can be used as medicine and viscose fillers and other light chemical products raw materials. Although the content of some ingredients is small, it has special economic value. Therefore, to carry out the study of the use of leaves is of great significance.
