摘要
为提升我省沿海防护林体系的建设质量,针对原有马尾松、木麻黄病虫害危害严重等现状,选择连江县东湖镇飞石村种植麻竹纯林、竹木混交林、混交竹林3种类型,采集其土壤样本,分析土壤理化性质。结果表明:混交竹林地土壤容重最小,土壤毛管持水量、孔隙状况指标值在不同土层均大于其他2种竹林地。3种竹林地表土层土壤有机质、全氮、全磷含量均高于心土层;除竹木混交林地在春季心土层全钾含量高于表土层外,其余2种竹林地表土层全钾含量均大于心土层或大致在同一水平。通过试验,表明在连江县沿海山地营造竹林对改良土壤物理性质具有较明显的作用;根据不同竹林类型选择在不同季节采用测土配方施肥,可有效地提高沿海防护林地生产力,对竹子产笋量起到较好的效果;同时,采取多树种造林,可解决沿海防护林造林树种单一、结构简单、抵御自然灾害功能较弱等问题,对提高沿海森林生态功能、促进沿海地区经济发展等具有重要意义。
In order to improve the construction quality of coastal shelter forest system,aiming at the serious pests and diseases status in the original mason pine and Casuarina forest,three types of forest plots including the pure Ma bamboo forest,the mixed bamboo and wood forest and the mixed bamboo forest at Feishi Village of Donghu Township of Lianjiang County were selected for the collection of soil samples and analysis of soil physical and chemical properties.The results show that,the soil volume weight is the lowest at the mixed bamboo and wood forest plot while the index value of soil capillary capacity and porous at different soil layers are higher than the other 2 plots.The content of soil organic matter,total nitrogen and total phosphorus at the topsoil layer are higher than the subsoil layer in these 3 plots.Except the content of total potassium at the subsoil layer in the mixed bamboo and wood forest land is higher than the topsoil layer in spring season,the content of total potassium in the rest 2 plots are higher or equal to the subsoil layer.Through the experiment,it shows that the plantation of bamboo forest has the obvious effect on the improvement of soil physical and chemical properties.The soil testing and formula fertilization adopted in different seasons and in different types of bamboo land will effectively improve the productivity of the shelter forest at coastal zones and will bring the high yield of the bamboo shoots.Meanwhile,the application of multiple species afforestation will solve the problems of coastal shelter forests such as single tree species,simple structure and weak capacity of resisting natural disasters,etc.It has the important meaning to the improvement of the coastal forest ecological function and the development of economy in the coastal areas.
