高钙植物桤叶唐棣引种试验初报?

开展高钙植物桤叶唐棣引种试验研究，目的是了解该浆果树种在黑龙江省东部地区的适应性，从而为黑龙江省浆果和林业发展增添新的经济树种和绿化树种，为地方经济引入一个新的增长点，此项研究有着广阔的发展前景。2008年黑龙江省绥棱地区从辽宁省干旱地区造林研究所引入桤叶唐棣‘Thiessen’、‘Martin’、‘Honeywood’和‘Smoky-3’4个品种，进行栽培试验。4年试验结果表明，桤叶唐棣根系萌动在3月下旬-4月初，4月下旬-5月中旬展叶抽梢，5月下旬开花，花期为7~10天，果实成熟期为6月末-7月上旬，落叶在10月中、下旬。新梢生长期6-9月，当年新梢长60.75 cm，3年生平均树高96.5 cm，地径1.31 cm，平均单果鲜重1.43 g，平均单株萌生根蘖14株。此外，桤叶唐棣表现出极强的抗寒力和抗病虫性，为此，可以确定桤叶唐棣为高抗寒树种，能够在黑龙江省绥棱地区以及气候相似区域引种栽培。

Preliminary Experiment Report on Introduction of Amelanchier alnifolia of High Calcium Plant

To carry out the study of Amelanchier alnifolia of high calcium plant,the objective to understand the adaptability of this berry trees in eastern of Heilongjiang Province,which add new economic trees species for development of berry and forestry,introduce new growth point for local economy,the study has broad prospect.Suiling Area of Heilongjiang Province introduced and planted Amelanchier alnifolia about Thiessen,Martin,Honeywood and Smoky-3 from afforestation research institute of Liaoning Province in arid zones in 2008.The result of 4 years experiments showed that the roots of Amelanchier alnifolia sprouted in late March till early April,unfolded during late April and mid-May,it blossomed in late May,the blossoming period was 7-10 days,fruit maturation period was in late June till mid July,and leaves fell in mid to late October.The new shoot growth in June to September,the length of new shoot of was between 60.75 cm in first year,the average height of 3 years old was 96.5 cm,and ground diameter was 1.31 cm,the fruit fresh average weight was 1.43 g,the average numbers of spouts was 14,in addition,Amelanchier alnifolia showed very strong cold resistance and disease resistance,so that it was a higher cold resistance plant,it could be introduced and cultivated in the Heilongjiang Province of Suiling Area and other regions with similar climates.
