The present invention relates to a cultivation method for speeding up the growth of beech and improving the ornamental characteristics of its leaves. Specifically, through thinning, the canopy density between beech forests is not higher than 80%, and the ground diameter of beech is 2.0-18.0 cm. In March-July, urea is topdressed 20-180 g per plant per month according to the size of the tree. In mid-August, 1/2 to 3/4 rings of bark were the main branches of ring injury, and the appropriate depth of ring injury was 0.2 to 0.3 cm. In mid-September, \0.5% potassium dihydrogen phosphate + 3% sucrose + 2% hydrogen peroxide\ mixture was sprayed on the leaves once to promote the formation of leaf color substances. The method can increase the growth of beech by more than 8%, promote the color change of beech leaves to purple or red, and advance the color change period by 7 to 10 days, which is beneficial to improve the economic value and the ornamental characteristics of beech leaves.
【技术实现步骤摘要】
一种加快红榉生长及改善叶色观赏性状的栽培方法
本专利技术涉及一种加快红榉生长及改善叶色观赏性状的栽培方法,尤其是,涉及加快红榉生长量、提高其叶色观赏价值的方法,是一种使红榉叶片变色期提前的方法,可满足秋冬季游客观叶的需要。
技术介绍
红榉为榆科落叶乔木,其树皮铁青色,成熟叶片微红至深红,是重要的用材、生态景观兼具型树种。近年来,由于苗木市场走低,生态景观、用材兼具的树种培育已经引起业内的重视,如一些部门急于寻找杨树的替代品种:在合肥市北一环等区域正在实施“红榉替换杨树”的工程。红榉生长快,树形高大,寿命长,观赏价值较高,是树种升级换代的重要备选树种,对于丰富林网树种,保持森林覆盖率稳步增长意义重大。国内对红榉的研究主要集中在栽培、实生选育、组织培养和生物学特性等方面。赵旺兔等(2003)对红榉叶的解剖构造、叶肉细胞超微结构和木材的发育解剖学进行了一系列的研究。黄利斌等(2012)研究了秋季不同叶色红榉色素含量变化。王旭军等(2013)研究了红榉不同种源叶片形态性状变异。窦全琴等(2014)研究了大叶红榉无性系性状的早期变异。通过恰当的栽培措施,加快红榉生长的同时, ...
