Study On The Cutting Test Of Aqueous Wax

Ligustrum obtusifolium is one of the commonly used shrub species in the green space of northern China.It has the characteristics of high survival rate and strong resistance.However,in the production practice,there will be a lack of seedlings,especially the lack of local seedlings.In order to solve this problem,the cutting experiment of Ligustrum obtusifolium was conducted on the opportunity of the study for postgraduate thesis.The experiment was arranged using orthogonal test with four factors and four levels.From the perspective of multiple indicators and multiple levels,the factors that may affect the rooting and survival of shoot cutting seedlings,and the level and combinations of the factors were discussed.The test results are as follows.?1?The optimal level combination of water wax in the orthogonal test is A₃B₃C₂D₁,ie,the ratio of matrix is 7:3,the length of cuttings is 15cm,the time for soaking rooting powder is 30min,and the concentration of rooting powder is clear water.The length of the B-factor insertion is the most important factor.?2?In the orthogonal test of water wax seedlings,the optimal level combination of seedling height increment is A3B3C2D1,ie the matrix ratio is 7:3,the cutting length is15cm,the time for soaking the rooting powder is 30min,and the rooting powder concentration is clear water.The length of the B-factor insertion is the most important factor.?3?The optimal level combination of root length of water wax orthogonal test is A1B3C1D1,ie matrix ratio is 7:3,cutting length is 15cm,time for soaking rooting powder is 60min,and rooting powder concentration is clear water.The D factor rooting concentration is the most important factor.?4?The optimal level combination of root number of water wax orthogonal test is A₂B₃C₁D₃,ie,the matrix ratio is 6:4,the cutting length is 15cm,the time for soaking the rooting powder is fast,the rooting powder concentration is 1000ppm.The length of the B-factor insertion is the most important factor.?5?In the orthogonal test of water wax leaves,the optimal level combination of the increment of leaves is A3B3C2D3,ie the matrix ratio was 7:3,the length of the cuttings was 15cm,the time for soaking the rooting powder was 30min,and the concentration of the rooting powder was 1000ppm...The length of the B-factor insertion is the most important factor.?6?The optimal level combination of leaf area of water wax orthogonal test is A₃B₃C₂D₁,ie the ratio of matrix was 7:3,the length of cuttings was 15cm,the time for soaking rooting powder was 30min,and the concentration of rooting powder was clear water.The length of the B-factor insertion is the most important factor.?7?The optimal level combination of dry weight of root in test is A₃B₃C₂D₂,ie matrix ratio is 7:3,cutting length is 15cm,time for soaking rooting powder is 30min,and rooting powder concentration is 500ppm.The length of the B-factor insertion is the most important factor.?8?The optimum level combination of dry weight of aerial parts in test is A₃B₃C₂D₂,ie matrix ratio was 7:3,cutting length was 15cm,time for soaking rooting powder was30min,and rooting powder concentration was 500ppm..The length of the B-factor insertion is the most important factor.?6?Orthogonal test of water wax The optimal level combination of leaf area is A₃B₃C₂D₁,matrix ratio is 7:3,cutting length is 15cm,time for soaking rooting powder is30min,and rooting powder concentration is optimal for clear water.The length of the B-factor insertion is the most important factor.?7?The optimum level of root dry weight for water wax orthogonal test is A₃B₃C₂D₂,matrix ratio is 7:3,cutting length is 15cm,time for soaking rooting powder is 30min,and rooting powder concentration is 500ppm.Optimal.The length of the B-factor insertion is the most important factor.?8?The optimum level combination of dry weight of aerial parts of water wax was A₃B₃C₂D₂,matrix ratio was 7:3,cutting length was 15cm,time for soaking rooting powder was 30min,and rooting powder concentration was 500ppm.For the best.The length of the B-factor insertion is the most important factor.
