薰衣草移栽苗栽培因素最优组合研究

Study on Optimal Combination of Cultivation Factor for Lavender Transplanting Seedling

为筛选出最适合鄂尔多斯园林植物景观应用的最优因素组合,对薰衣草实生根移栽苗在多种因素水平条件下生长的试验对比观测,设计正交试验。结果表明:齿叶薰衣草、移栽前铺地膜、施加复合肥且灌水周期为每3d一次的成活率最高;齿叶薰衣草、露地栽植、施加氮肥且灌水周期为每3d一次植物苗高平均增长量最多;齿叶薰衣草、移栽前铺地膜、施加复合肥且灌水周期为每7d一次植物冠幅平均增长量最多。选用宽叶薰衣草和齿叶薰衣草,通过露地移栽和移栽前铺地膜提高移栽苗成活率,移栽后施加氮肥和复合肥增加薰衣草苗高和冠幅增长量,齿叶薰衣草、移栽前铺地膜、施加氮肥、灌水周期为每3d一次为正交试验的最优因素组合。

In order to select the optimal combination of factors most suitable for landscape plants in Ordos,lav- ender solid rooting transplanting seedlings grown under a variety of factors horizontal were compared and ob- served,orthogonal experiment was conducted. The results showed that dentata lavender, spread mulch before transplanting,applying compound fertilizer and irrigation every 3 d had the highest survival rate;dentata laven- der,open field planting,applying nitrogen fertilizer and irrigation every 3 d , the average height increment was the highest; teeth leaf lavender, spread mulch before transplanting, applying compound fertilizer and irrigation every 7 d,the plant crown was maximum. Taking Lavandula latifolia and tooth leaf lavender, through the open field before transplanting and laying mulch transplanting, seedlings transplanted survival rate increased, and the amount of lavender height and crown growth were increased. The optimal combination was that nitrogen fertil- izer after transplanting tooth leaf lavender,spread mulch before transplanting and irrigation every 3 d.
