雄安新区千年秀林有机肥施用效果研究

The Effect of Organic Fertilization Application in Mil ennium Forest in Xiong’an New Area

研究雄安新区千年秀林不同类型有机肥施用效果,对造林2a后的白蜡、银杏、国槐、栾树和油松选取不同有机肥增量和不施肥开展试验,对施肥1年后树种的径生长、三维绿量和施肥前后土壤有机碳含量进行对比分析。结果显示,相比未施肥,施肥作业大都能显著促进树种径向生长,不同肥料在促进树种径向生长程度上存在差异,有机肥施用可提高速生树种冠体三维绿量,对慢生树种银杏冠体三维绿量促进效果不佳,能够显著提升土壤表层有机碳含量,促进林木径向和三维绿量增加,且能有效提高林地表层土壤碳储量。以上研究为雄安新区千年秀林及其林地资源的可持续发展提供依据。

The application effect of different types of organic fertilizer in millennium Xiulin of Xiong’an New Area was studied,and different organic fertilizers of ash,ginkgo,locust,paniculata and Pinus tabulaeformis were selected with increment and without fertilization,and the diameter growth,3 D green amount and soil organic carbon content were analyzed one year after fertilization.The results show that compared with no fertilization,fertilization mostly can significantly promote the radial growth of tree species,different fertilizer in?promoting the tree species radial growth degree difference,organic fertilizer application can improve the fast tree crown 3 d green,the slow species ginkgo crown 3 d green promotion effect,can significantly improve the soil surface organic carbon content,promote forest radial and 3 d green increase,and can effectively improve the forest surface soil carbon reserves.The above research provides a basis for the sustainable development of the millennium beautiful forest and its forest land resources in the Xiong’an New Area.
