Research On Container Nursery Technique For Soil And Water Conservation Seedlings In The West Of Liaoning Province

This article takes the characteristics of western Liaoning and systematically studies the container nursery technique for the three kinds of soil and water conservation-type seedlings (Black locust, Scotch pine, Chinese pine).This test contains two parts,the first part is the three different container types studied.Through the three different container types,the author has analyzed and evaluated in accordance with the morphological index and the biomass index.It is showed that the container A (5cm (length) * 5cm (width) * 20cm (height) hard plastic format container) is the best type to cultivate Black locust and Chinese pine,while the container B (8cm (diameter) * 11cm (height) plastic film bags) is best for Scotch pine.The second part is to research the different growth matrix.Through the five kinds of matrix tests showed that container seedlings of Black locust, Scotch pine, Chinese pine are cultivated in the experimental field,the result is matrixâ…£(3 / 4 of the raw soil + 1 / 4 of peat) is good for Black locust growing, Scotch pine grows best in matrixâ… (1 / 2 of the raw soil + 1 / 6 of peat +1 / 6 of perlite +1 / 6 of sawdust) and matrixâ…¡(3 / 5 of the raw soil + 1 / 5 of peat +1 / 5 perlite) is best for Chinese pine container seedlings. Depending on the characteristics of the container seedlings suitable for using in different container types and different matrix,the author designs the technical processes of the container nursery for the three kinds of soil and water conservation seedlings.For soil and water conservation in western liaoning contributes to the work force.
