一、苗床管理苗床管理是实现壮苗的重要手段,应据烟苗适生条件进行科学管理。种子从萌发到成苗,不同生育时期对环境条件的要求有很大不同。创造适合幼苗健壮生长的条件,正是苗期管理的要求。为了达到壮苗标准,前期(出苗期、十字期)的主攻方向是早出苗,防死苗。技术上以促为主,应在一定限度内保持床土水份和温度为主要手段。后期(生根期、成苗期)的主攻方向是促苗墩实,锻苗老健,技术上以控为主,适当调增苗床光
First, the seedbed management Seedbed management is an important means of achieving strong seedlings, should be based on the conditions of tobacco seedlings for scientific management. Seeds from germination to seedling, different stages of the environmental requirements of very different requirements. It is the requirement of seedling management to create suitable conditions for the robust growth of seedlings. In order to achieve strong seedling standard, early (seedling, cross) the main direction is early emergence, anti-seedlings. Promote the main technical, should be maintained within a certain limit of bed soil moisture and temperature as the main means. Post-stage (rooting, seedling) is the main direction of promoting Miao pier reality, forging seedlings health, technical control-based, appropriate to increase seedbed light
