研究目的 小麦主杆与分蘖的相互关系,一直是生产实践上和科学研究上争论的重要问题之一。以往许多人利用示踪原子法进行研究,指出了主杆与分蘖根系吸收的养分可以相互转运。但对下列几个关键问题仍然缺乏深入系统的研究。 (一)不同生育阶段,主杆和不同节位分蘖根系的吸收养分能力及其运转规律。
Research purposes The correlation between wheat stem and tiller has always been one of the most important issues in production and scientific research. In the past many people using tracer atom method to study, pointed out that the main rod and tiller root absorption of nutrients can transport each other. However, there is still a lack of in-depth and systematic research on the following key issues. (A) absorption of nutrients and their operating rules at different stages of growth, main stem and tillering roots at different nodes.
