花卉的分類方法有很多種,本文只簡要介紹一下草本花卉的生物特征分類及在綠化工程中應用的相關知識。 There are many ways to classify flowers, and this paper only briefly introduces the biological characteristics of herbaceous flowers and the relevant knowledge applied in greening engineering. 草本花卉的定義是指:花卉的莖木質部不發達,支持力弱的花卉(也稱草質莖)。 The definition of a herb flower is that the stems of flowers are not well developed, and they support weak flowers (also known as grass-stalk). 其種類包括一、二年生草花、宿根花卉(多年生花卉)、球根類花卉、多年生常綠草本植物及水生花卉、蕨類植物等(本文略)。 The type, including a, biennial and perennial root flowers (perennial flowers), bulbous flowers, evergreen perennial herbs and aquatic flowers and plants, ferns, etc (slightly) in this paper. 草本花卉在綠化中的應用 Herb flowers are applied in greening (一)一、二年生草花 (1) one, two years old grass flower 1.多為溫室育苗后栽植 Many plants are planted after planting 移栽時,植株密度北方地區一般為20株至25株/平方米,少數品種36株至45株/平方米(如藍花鼠尾草等),特殊品種按設計密度施工,但必須防止栽植過密引起植株徒長、倒伏和病蟲害滋生。 When transplanting, plant density in the north are generally 20 to 25 strains plants/square meters, a few varieties of 36 strains to 45 plants/m2 (such as blue flower sage, etc.), special varieties according to the density of design construction, but must prevent plant too close cause moderate growth, lodging, and plant diseases and insect pests. 2.在工程項目中直播(播種) Live (sowing) on projects 播種前必須對厚30厘米的土壤進行整地、施肥,土壤不適的,需進行土質改良。 Before sowing, the soil must be ground, fertilized, and the soil is not suitable for soil improvement. 播種時,要根據不同品種的播種量計算進行播種,播種量過多,易增加除草成本,過密,則影響花卉正常生長勢和觀賞效果?,F在草花播種量多在3克至5克/平方米之間,多數品種種子價格多在100元至400元/公斤,平均播種成本為1元至2.5元/平方米。 Sowing, according to the different varieties of rate calculation, sowing rates too much, easy to increase the cost of weeding, too close, affect the normal growth potential flowers and ornamental effect. Now brews rate more between 3 g to 5 g/m2, most varieties seeds price is in 100 yuan to 100 yuan/kg, more average planting cost 1 yuan to 2.5 yuan/square meters.
