自从伦琴发现X射线以来,关于X射线的学说及各种实际应用的研究,现已发展成一个专门的学科。由于它波长小于0.2×10~(-10)。厘米,具有很强的穿透力,所以医学上已普遍采用来检查和治疗病患;工业上也广泛应用其对各种金属和非金属材料进行探伤;生物学等方面也越来越广泛地利用X射线。现仅就X射线在林业方面的利用作简单介绍。一、在森林病虫害防治方面的应用 1.通过照射使害虫不育和致死自从伦琴首次发现X射线可以导致昆虫不育后,许多国家都在进行利用X射线防治害虫的研究。其方法:一种是直接在害虫栖居地应
Since Roentgen discovered X-ray, the research on X-ray theory and various practical applications has developed into a special subject. Because of its wavelength less than 0.2 × 10 ~ (-10). Cm, with a strong penetrating power, it is widely used in medicine to check and treat patients; it is widely used in industry to detect various metal and nonmetallic materials; and biological aspects are also more and more widely Using X-ray. Now only on the use of X-ray in forestry for a brief introduction. First, the application in the prevention and control of forest pests 1. Sterilization and lethality of pests by irradiation Since Roentgen first discovered that X-rays can lead to infertility in insects, many countries are conducting research using X-ray pest control. The method: one is to be directly in the habitat of pests
