以当归苗为材料,设计单因素试验,研究了赤霉素浸根对温室当归苗出苗及生长进程的影响。结果表明,赤霉素能有效打破温室当归苗的休眠,并显著促进其出苗进程,对其生长进程有一定影响。当用80 mg/L赤霉素浸根时,纯土苗和基质苗的出苗率分... 以当归苗为材料,设计单因素试验,研究了赤霉素浸根对温室当归苗出苗及生长进程的影响。结果表明,赤霉素能有效打破温室当归苗的休眠,并显著促进其出苗进程,对其生长进程有一定影响。当用80 mg/L赤霉素浸根时,纯土苗和基质苗的出苗率分别达到58.79%和43.76%,当归产量分别达到4 267.65 kg/hm^2和4 116.60 kg/hm^2。 展开更多

Althoughwe still haven't a precise definition, there are some principles for justifying whether a systemis a complex system. The purpose of this article is to reveal some of such principles. Onthe basis of them, the concept of a system with complexity is proposed. They may helpus to distinguish a real complex system from complicated objects in common sense. Thenwe propose some fundamental problems faced by the study of systems with complexity. 展开更多
