Study On The Technology Of Korean Pine Fruit Forest Silviculture

This study researched on Korean pine fruit forest cultivation technology in Mudanjiang, carrying out extensive research on selecting fructification superior stand and superior tree, grafting, planting fruit forest, operation density and pollarding, scarifying, laminating, introducing AraliaMandshuricamaxim, best seeding date and phenological phase of Korean pine. It has put forward the theories about classification management of artificial Korean pine forest, directive cultivation of Korean pine fruit forest, timber with fruit forest and timber forest, and drawn up the standard and selection method of fructification superior stand and superior tree , and selected (1)fructification superior stand matrixes , 1036 pre-selection fructification superior trees and (2) primary fructification superior trees .The study have gotten conclusions , including 3 kinds of improvement method of conjoining marrow cambium, graft best time , standard of selecting stock, graft plant management method, selection of regenerating Korean pine fruit forest plot, mixed forestation technology ,method of protecting young plantation , the advantage of mixed planting Korean pine and Larch, optimal planting density of rebuilding Korean pine fruit forest, accelerating Korean pine seed by pollarding, scarifying and laminating, the relation between density of adventitious Aralia Mandshurica maxim and economic benefit and the best seeding date. Scientific may increase seeds of Korean pine fruit forest. Cultivating Korean pine fruit forest is a supplemental practical technology that has extensive application prospect. It may not only get better social benefit and ecological effective, but get considerable economic profit.
