The Effect Of The Difference Between Irrigation Amount And Cycles On The Lavender

Ordos is located in the semi-arid grassland. Obviously continental climate, with numerous sandstorm, dramatic daily temperature swings, drought, especially in the early spring the sandstorm also serious harmed. All of those climate factors make the Ordos landscape plant cultivation and introduction limited to some extent, especially in drought and shortage of water, It has become an important limited factor on plant cultivation.Lavender belongs to the collectively of Lamiaceae Lavandula plants. It have great application value in landscape with flowering plant and foliage tree, also with the function of potpourri.This thesis via introduction,domestication and lavender grows in Yunnan to expand the scope of its cultivation area. The main purpose is to via the artificial cultivation fertilizer types and fertilizer rate under the condition of drought resistance exercise test. To research and explore the lavender,which is the most suitable to ordos in artificial cultivation mode and technique of nursery stock cultivation method. Put it another way, It can laid a academic and practical foundation to enrich the type of Ordos landscape plant cultivation.This paper on the basis of lavender orthogonal experiment.via the analysis of the16orthogonal experiment research, the soil moisture content, plant survival rate, seedling height, leaf area increment and a series of in-depth data analysis, and to find out the most suitable for growing the effects of lavender and soil conditions, and to via the test to testify:(IK In the midst of orthogonal experiment on the survival rate of influence factors, fertilization> water cycle factors> soil factors> irrigation water. When the fertilizer rate is600PPM, water cycle3days, irrigation water350mm, the ratio of soil matrix are sand:loam:dirt=4.5:4.5:1and lavender as the highest survival rate.(2)-. In the midst of orthogonal experiment on seedling height of the influence factors, water cycle factors> fertilizer factors> soil factors> irrigation water. In no fertilizer condition, irrigation cycle for3days, irrigation water is600mm. the ratio of soil matrix for sand:loam:dirt=3:6:1and lavender seedlings were the highest high growth. (3)、In the midst of orthogonal experiment on increment of leaf area.fertilization> water cycle factors>irrigation water>soil factors. In no fertilizer condition. irrigation cycle for3days, irrigation water is600mm. the ratio of soil matrix for sand: loam:dirt=3:6:1and lavender leaf area growth is highest.(4). If the lavender highest survival rate, shoot height, leaf area increment highest were satisfied.In no fertilizer condition, irrigation cycle for3days, irrigation water is600mm, the ratio of soil matrix for sand:loam:dirt=4:4:2, lavender seedling survival rate, seedling height, leaf area growth to achieve the optimal.
