Study On Introduction And Cultivation Technology Of Lobed Birch

In this study,the techniques of seed collection,seeding,seedling management,and suitable cultivation sites were selected and integrated,and a complete introduction and cultivation technology system was formed,which was afforestation for artificial timber forest,ecological restoration of sandy land,and afforestation of mine land.New coastal species have been added to coastal shelterbelt construction and urban landscaping.1.The effects of several different germination methods on the germination rate of Betula platyphylla were studied.The results showed that the seed germination rate of C.chinensis was the best germination method in open-air mixed burial and open-air mixed burial.The mixed sand germination method is second.2.Through the investigation on the effects of seedling results of different soil textures,it is found that the soil texture of sandy soil is most suitable for the seedling cultivation of C.chinensis,followed by the middle soil,and the worst performance of the seedlings is clay,so the soil texture is clay.It is not suitable for seedlings of birch buds.3.The growth survey of different cultivation areas found that there was no significant difference in the cultivation effects of the types of barren hills and returning farmland to forests.The depression was better than the cutting sites,barren hills,and returning farmland to forests.The mines dominated by coal gangue grow normally and can bloom normally.The sandy soil is suitable for the growth of the birch,and the growth of the clay is lagging and there is a dead phenomenon.4.Investigation of the growth of different cultivation areas.The Zhanggutai test area in Zhangwu County is a deserted soil wasteland with a thin humus layer and poor water storage capacity,but good gas permeability and good annual average temperature.5.Benefit evaluationIt is an excellent material for constructing seed orchards.Its trunk shape is good,its resistance is strong,its growth rate is fast,and its geological requirements are not strict.The bud can be propagated by cutting and cutting the cuttings.The trunk of the weeping birch isstraight,the branches are soft,the bark is white,the autumn leaves are yellow,and the crown is conical.Because of its beautiful shape and beautiful ornamental value,it is an excellent tree species for urban and rural greening.
