Description

A kind of method for cultivating monkeyhead rhododendron leaf in basic soil area
Technical field
Cultivate evergreen in basic soil area the present invention relates to a kind of outdoor planting technique of monkeyhead rhododendron leaf, more particularly to one kind The method of cuckoo, belongs to technical field of flower cultivation.
Background technology
Cuckoo is the general designation of Rhododendron (Rhododendron L.) plant, refers to Ericaceae (Ericaceae) cuckoo Flower plant, is world-renowned Alpine Wild Ornamental Plants, is also one of ten traditional big famous flowers of China, is commonly called as azalea, horse oriental cherry etc..Its Floral leaf is in great numbers when blooming, and pattern is gorgeous, among all ornamencal flower and trees, deserves to be called flower, Ye Jianmei, is preferable miniascape and pot flower material Material, it is deep to be liked by masses, it is the city flower of 14 provinces and cities such as Wuxi, Shenzhen, Changsha, with Chinese rose, sweet osmanthus same column Chinese city city flower The top three (Liu Xiaoqing etc.,《Application of the cuckoo in gardens》, modern garden, 2013,10 (10):37-40.).Cuckoo is in full generation Boundary is widely distributed, it was reported that the current whole world there are about the kind of rhododendron more than 960, and China is that world's azalea resource is the richest Rich area, is the distribution center of the world of the platymiscium, 542 kinds of initial species is distributed with, more than half of the world total is accounted for, wherein About 420 kinds of endemic species (Zhang Mingli etc.,《Alpine rose cultivation technique research》, Agriculture of Anhui science, 2005,33 (6):1008- 1009.).But cuckoo trace is difficult to find in many urban landscapings of China, assortment list one also few using kind.Mainly Reason is the neutral flowers of Genus Rhododendron, many nice and cool weathers of happiness, acid soil (Zhang Weiyan,《The cultivation management skill of northern azalea Art》,《Northern gardening》, 2008 (6):157-158), it is Southwestern China and Central-South typical oxylophyte (Chinese Plants Will editorial member,《Chinese Plants will》, 57 (2):386.).
China's soil acidity or alkalinity can be divided into 5 grades:pH<5.0 be highly acid, and pH5.0~6.5 are acidity, and pH6.5~7.5 are Neutrality, pH7.5~8.5 are alkalescence, pH>8.5 be strong basicity.Soil acidity or alkalinity has a major impact to soil nutrient availability, PH6~7 it is slightly sour under the conditions of, soil nutrient availability highest, most beneficial for plant growth.In acid soil easily cause P, K, The shortage of the elements such as Ca, Mg, easily causes Fe, B, Cu, Mn, Zn etc. shortage in strong basicity soil.Soil acidity or alkalinity can also shadow Ring microorganism activity so as to influence nutrient availability and plant growth (Chen Shaohua etc.,《Brief talk gardens acid-base property soil Modification method》,《Tropical Forest》, 2008,36 (4):10-11.).Because cuckoo likes acid soil, also have to illumination, liquid manure etc. High requirement, therefore be used for potted flower, potted landscape, limit cuckoo in urban landscaping application (Wang Wenfei etc.,《Cuckoo Cultivate six main points》,《Anhui forestry》, 2004 (6):30.;Yang Tieshun etc.,《The cultural method of azaleas adapting to boreal climate》, Chinese patent ZN201010214880).Cultivating and growing likes the plant of acid soil in alkaline soils, is usually to carry out soil Acidifying improvement (Dang Hongfa,《The acidifying improved method of basic soil》, Chinese flower potted landscape, 2000 (6):19.).To the complete of planting site Portion's soil carries out acidifying improvement, and not only workload is big, and the regional underground water of basic soil is generally alkalescence, it is easy to permeate back improvement The soil crossed, makes it turn into alkalescence again;In urban landscaping in practice, the plant that different habits and sight are used more is taken With plantation, the acid soil after improvement is not suitable for happiness neutrality and alkaline soil plant growth.Therefore, whole soil of planting site are carried out Acidifying improvement, has little significance, for a long time, researcher can not realize in basic soil area to the cultivation of cuckoo gardens and application The extensive outdoor cropping and afforestation application of cuckoo.
At present, the domestic cuckoo generally planted has Rhododendron hybridun, Japan cuckoo, Mao Juan, Xia Juan, spring cuckoo etc., is evergreen Cuckoo, domestic and foreign scholars are less to the technique study that monkeyhead rhododendron leaf is cultivated in basic soil area.Qi Haifeng etc. discloses high mountain Du Cuckoo gardens cultural method (《Cultivate in alpine rose gardens》,《Chinese flower gardening》, 2013 (8):26-27.).Alpine rose because It is thermo-labile, it is more difficult to cultivate, it is rare plantation (Fang Yonggen,《The Cultural technique of monkeyhead rhododendron leaf》,《Flowers and trees bonsai flower gardening》, 2012(3):16-17.);And the plant type of alpine rose is larger, and the monkeyhead rhododendron leaf such as eastern cuckoo, western cuckoo, spring cuckoo of domestic common cultivation Plant height is generally less than 200cm, thus the monkeyhead rhododendron leaf of the open field culture method of alpine rose and small plant type has larger difference.It is old few China etc. disclose by physics and water conservancy improve meta-alkalescence soil measure (Chen Shaohua etc.,《Brief talk changing for gardens acid-base property soil Good recipe method》,《Tropical Forest》, 2008,36 (4):10-11.), method is more general, not yet for Genus Rhododendron Subgenus Hymenanthess The characteristics of plant, sums up a set of practicable method.
