春天的阳光虽然柔和,却会伤害果树,这是园艺家所熟知的。通常采用的保护措施是秋末落叶后存树干刷上白粉和石灰,或缠上云杉枝或麦秆。但这些办法使用劳力较多,效果也不太理想。全苏化学工业科学研究设计院莫斯科分院,研制出一种水质乳状护树液,将其涂到树干上几年也不会脱落,反光性能比白粉和石灰强得多。护树液本身又是驱虫剂,而且具有促使树皮上小损伤愈合的功能,但对人体完全无害。
Although the spring sunshine soft, it will hurt fruit trees, which is well known to the horticulturist. Commonly used protective measures are stored in late autumn leaves of the trunk brush white powder and lime, or wrapped around spruce branches or straw. However, these methods use more labor and the effect is not very satisfactory. All-Soviet Chemical Industry Research and Design Institute of Moscow branch to develop a water-based emulsion of tree-care liquid, the trunk will not be coated on the trunk a few years will not fall off, reflective properties than white powder and lime much stronger. The bark itself is repellent, but also has the function of promoting small wound healing on the bark, but it is completely harmless to the human body.
