运用各种先进的研究方法,对于解决林业上一系列的实际问题是有重大意义的。示踪原子法即是其中之一。现在科学家们已经发现了很多放射性物质,其中有磷、钾、硫、钙、铁等放射性同位素。我们曾利用放射性磷(P~(32))的同位素作为研究松树和云杉苗木吸收磷肥的指示剂。
Using a variety of advanced research methods is of great importance to solving a series of practical problems in forestry. Tracer atom method is one of them. Now scientists have found a lot of radioactive material, including phosphorus, potassium, sulfur, calcium, iron and other radioactive isotopes. We have used isotopes of radioactive phosphorus (P ~ (32)) as an indicator of the uptake of phosphate fertilizer by pine and spruce seedlings.
