一、目的农作物所需要的养料元素除了碳、氢、氧、氮、磷、硫、钾、钙、镁、铁等十种之外,还需要一些分量非常少的元素,如硼、铜、锰、锌、钼等等。这些微量元素之中,硼素是最重要的微量元素之一。本试验的目的在于了解硼素对于豌豆生长、发育的影响。二、试验材料及方法本试验是用克诺普培养液做基本溶液,在混合培养液中加入硼酸。 (1)克诺普培养液:把下列盐类溶解在1升蒸馏水中。
First, the purpose of crop nutrients required in addition to the elements of carbon, hydrogen, oxygen, nitrogen, phosphorus, sulfur, potassium, calcium, magnesium, iron and other ten, but also some very small components such as boron, copper, manganese , Zinc, molybdenum and so on. Among these trace elements, boron is one of the most important trace elements. The purpose of this experiment is to understand the impact of boron on pea growth and development. Second, the test materials and methods This experiment is to do basic solutions of kenop culture medium, boric acid was added to the mixed medium. (1) Knop medium: The following salts were dissolved in 1 liter of distilled water.
