摘要
青柰李在张家界地区生长快、果实品质优良,但植株具有一年多次抽梢和一年生梢容易旺长等特点。采用抹芽、缓放和疏枝3种修剪方式对5年生和10年生青柰李结果树的一年生枝梢进行生长调控,发现青柰李结果树的一年生枝梢具备成花结实能力,无论是在5年生还是15年生结果树的树体上均可留有充足的一年生枝梢作为结果枝,其中径粗0.5～2.0 cm的一年生枝梢平均每30 cm枝长可留住1个果实,并且果实的平均重量超过150 g、可溶性固形物含量达13%左右,即径粗0.5～2.0 cm的一年生枝梢可作为张家界青柰李结果树的有效结果枝用于果实生产。
Qingnai plum(Prunus salicina)can grow fast and has good fruit quality in Zhangjiajie area,but it has the characteristics of multiple shooting in one year and easy to grow fast.The annual shoots of 5-year and 10-year old Qingnai plum were regulated by three pruning methods:deleting buds,leaving or eliminating branches were used to control the plant growth.It was found that the annual shoots of fruit trees of Qingnai plum had the ability of flowering and fruiting.There were plenty of annual shoots on the trees of 5-year-old and 15-year-old fruit trees,among which the annual shoots of 0.5-2.0 cm in diameter averaged 30 cm in length can have one fruit retained,and the average weight of fruit was more than 150 g,and the content of soluble buried solids was about 13%.That is to say,the annual shoots with a diameter of 0.5-2.0 cm could be used as effective fruiting branches of Zhangjiajie Qingnai fruit tree for fruit production.
