The Research On Hardwood Cuttings Of Three Kinds Of Lavender In Bare Land

Lavender belongs to the collectively of Lamiaceae Lavandula plants, it not only have a beautiful colar,but also with the function of potpourri,and the plants have a highly ornamental. Erdos is located in the semi-arid area,but Lavender suitable lor planting in a vast area.This paper research for hardwood cutting of Lavender in bare land,even find the best Artificial cultivation mode and Seedling cultivation scheme of Lavender in Erdos, plentiful landscape of the Erdos.In this paper, use the L9 (34) orthogonal experiment, a total of 9 tests, each test three repeats. The four factors are the irrigation cycle, lavender’s varieties, protective measures at the early cottage and fertilization conditions. Focuses on the research on hardwood cuttings of three kinds of lavender in bare land, thus select suitable the cultivation of lavender growing environment The main results are as follows:1. The hardwood cuttage seed ings of three kind of lavender are have a larger organic demand, adding the right amount of fertilizer is promote the lavender growth; Lavandula angustifolia need high available nitrogen, available phosphorus and available potassium,that should be more compound fertilizer to promote its growth; Dentate lavender need high available nitrogen,that should be more nitrogen fertilizer to promote its growth; Spike lavender for high available phosphorus and available potassium needs, that should be more phosphate and potassium fertilizer to promote its growth.2. Every 3 days once poured water conducive to the height growth for dentate lavender and spike lavender’s hardwood cuttings.3. Use the plastic for protective measures in bare land at the early stage conducive to the growth of ground diameter for dentate lavender and lavandula angustifolia’s hardwood cuttings.4. Additional the urea is conducive to the growth the number of root for dentate lavender and lavandula angustifolia.5. Every 3 days once poured water, use the plastic for protective measures in bare land at the early stage and no fertilizer for plant the spike lavender that have the highestsurvival rate and rooting rate.6. The four factors in the experiment, the relationship between primary and secondary effects of survival rate of lavender is lavender’s varieties>protective measures at the early cottage> irrigation cycle fertilization conditions; the relationship between primary and secondary effects of rooting rate of lavender is lavender’s varieties>protective measures at the early cottage>fertilization conditions> irrigation cycle.
