以科尔沁沙地栽培的辽榛3号(84-226)、辽榛7号(82-11)和达维(84-254)3个品种平欧杂种榛(Corylus heterophylla Fish.×Corylus avellana L.)为研究对象,分析不同繁苗时间对沙地平欧杂种榛压条苗生根情况的影响。结果表明:3种平欧杂... 以科尔沁沙地栽培的辽榛3号(84-226)、辽榛7号(82-11)和达维(84-254)3个品种平欧杂种榛(Corylus heterophylla Fish.×Corylus avellana L.)为研究对象,分析不同繁苗时间对沙地平欧杂种榛压条苗生根情况的影响。结果表明:3种平欧杂种榛的生根率、生根数量、生根基径和生根长度均随压条时间推移呈下降趋势,且从6月30日起,各指标下降幅度明显。综合比较,在章古台地区对平欧杂种榛进行繁育苗木的最佳时间段是6月25日—6月30日。 展开更多

[Objective] The aim was to improve part of auto-control system of aquatic seedling breeding and to lay foundation for highly-efficient and stable use of the sys- tem. [Method] The executive and drive modules of the auto-control system were im- proved, after which real-time monitor, data display and alarm modules were tested on time. [Result] In the test, for the improved system, stability and sensitivity were enhanced; different components matched better; transmitting electric resistanc6 was reduced. [Conclusion] The research provides references for auto-control of water temperature and dissolved oxygen, and faults clearing in aquatic seedling breeding. 展开更多
