Study On Softwood Cutting Of Rosemary

Rosemary is the lamiaceae Rosmarinus evergreen shrubs,perennial,native to the Mediterranean coast is passed to all over the world,is an important ornamental plants and spices.Rosemary plant type for shrubs or vines,leaf is green,needle like leaves with strong,-clear,penetrating,pure and fresh grass incense;Design and color such as blue,lavender,pink and white,can send out a full-bodied fragrance.Rosemary essential oil has insecticidal,sterilization,anti-inflammatory effect and so on,is now widely used in perfumes,bath,cosmetics,shampoo,air fresheners,ant displacement agent,etc.,and have to rush through blood,eczema,antihypertensive,antibacterial beach,cancer and other pharmacological effects and is widely used in medicine,also can make water and soil conservation,afforestation,potted plants,such as purification and beautify the environment.As a result,the plant development and utilization potential,development prospect and high application value.This paper adopts the four factors and four levels of L16(44)orthogonal experiment were sprigs of rosemary.A total of 16 test,each test in three duplicates.The orthogonal test of four factors of culture substrate respectively,discharge time,concentration of abt,and rosemary.After a few months of observation,analysis under the condition of different treatment of rosemary softwood cutting experiment of cuttings rooting rate,root morphology such as root length,root dry weight of indicators.Through data processing and analysis can get the following results:(1)Different matrix,different time and different concentration of abt,different parts of the cuttings rooting of rosemary has a certain impact.Cutting is one of the most critical part of rosemary begins to take root.(2)Rosemary softwood cutting experiment of cutting seedlings rooting rate of orthogonal experiment the best combination for A3B1C1D3,perlite and peat soil ratio was 7:3.Time for every half an hour the 5 s of spray,abt concentration of 0 PPM,cutting parts half lignification of the optimal choice.Rooting rate of poor R value order of size of RD>RB>RA>RC.(3)Rosemary softwood cutting experiment of cutting seedling root length of orthogonal experiment the best combination for A3B3C1D3,perlite and peat soil ratio was 7:3.Time for half an hour every 15 s of spray water,abt concentration of 0 PPM,cutting parts half lignification of the optimal choice.Poor root long R values for order size RD>RA>RB>RC.(4)Rosemary softwood cutting experiment of seedling number of orthogonal test the best combination for A4B2C1D4,perlite and peat soil ratio to speak;Time for half an hour every 10 s of spray water,abt concentration of 0 PPM,cutting parts half lignification central for the optimal choice.The order of the root of the number of poor R value size of RD>RC>RB>RA.(5)Rosemary softwood cutting experiment of seedling orthogonal experiment the root effect index,the best combination for A3B2C1D3,perlite and peat soil ratio was 7:3.Time for half an hour every 10 s of spray water,abt concentration of 0 PPM,cutting parts half lignification of the optimal choice.Poor root effect index of the R value order of size of RD>RA>RB>RC.(6)Rosemary softwood cutting experiment of seedling orthogonal experiment of root dry weight and the best combination for A2B2C1D3,perlite and peat soil ratio was 6:4;Time for half an hour every 10 s of spray water,abt concentration of 0 PPM,cutting parts half lignification of the optimal choice.The order of the root of the number of poor R value size of RD>RB>RA>RC.(7)Of rosemary softwood cutting experiment of plant high growth was the best combination of orthogonal experiments were as A2B1C2D3,perlite and peat soil ratio was 6:4;Time for every half an hour the 5 s of spray,abt concentration of 0 PPM,cutting parts half lignification of the optimal choice.Poor root effect index of the R value order of size of RD>RC>RA>RB.(8)Unified consideration six indicators,according to the result of orthogonal experiment the beneficial arnd unprofitable principle,determine the rosemary softwood cutting experiment branch cutting seedling test,the best combination for A3B2C1D3,namely the substratum of perlite:lime = 7:3,discharge time for half an hour every 10 s,abt concentration of 0 PPM,central site for half lignification of cuttings.
