摘要
在杏园上建造大棚，对杏树大棚栽培中需要解决的主要问题进行了试验研究。结果表明：杏树一般在１２月底结束休眠（需低温量８６０小时左右），１月上旬扣棚较为适宜。棚内平均气温花期控制在１１℃～１３℃，夜间不低于６℃，果实第１速生期１３℃～１８℃，夜间不低于７℃，硬核期１８℃～２２℃，夜间不低于１０℃；第２速生期２２℃～２５℃，夜间不低于１５℃。采用蜜蜂传粉和人工授粉座果率可达３６．３１％和３５．４％；幼果膨大期，喷施０．１％硼酸，硬核期喷１００×１０６Ｂ９均可明显提高座果率。
Abstract The Result of apricot caltivation test in the plastic house showed that apricot trees usually end dormancy at the end of Dec.It is suitable for the house cover in the first ten day period of Jan. The mean temperatwre in the house is below:11℃～13℃during day and not lower than 6℃ in the night during floworing phase; 13℃～18℃ and not lower than 7℃ during the first fruit fast growing period; 18℃～22℃ and not lower than 10℃ during the perind of hardening kernel; 22℃～25℃ and not lower trcan 15℃ during the secondary fast growing period. Percentage of fertile fruit is higher by bee and artificial pollination and it also can be raised effectively by bop removal, spraying plant grown reglulator, etc.
