贵州鸟王茶产地土壤物理性状特征

Characteristics of Soil Physical Characters in the Producing Area of Niaowang Tea in Guizhou Province

为了探索垦植对山区茶园土壤性状的影响,促进茶产业经济与水土保持的协调发展,本文通过不同生态模式下贵州鸟王茶产地茶园土壤主要物理特征进行了对比研究。结果表明:鸟王茶产地土壤容重平均值为1.13g/cm3,鸟王茶产地土壤容重适宜茶树生长;土壤孔隙度平均值为51.89%,占总体样本数73.91%的土壤样品孔隙度值介于50%~60%之间,鸟王茶产地土壤孔隙状况适宜茶树生长;土壤毛管持水量平均为34.46%,土壤样品毛管持水量值介于30.00%~60.00%之间;鸟王茶产地土壤中砂粒含量最高,细粘粒含量最低。说明研究区域土壤侵蚀比较严重,对土壤养分具有吸附和固定作用的细粒在减少,土壤板结、沙化现象出现。总体上鸟王茶产地土壤物理性状良好。

In order to explore the impact of cultivation on tea plantation soil properties in mountainous areas and to promote the coordinated development of tea industry economy and soil and water conservation,this paper compares the main physical characteristics of tea garden soil of Niaowang Tea Guizhou production areas under different ecological models. The results showed that the average soil bulk density of Niaowang Tea was1. 13 g/cm3,the soil bulk density of Niaowang Tea tea was suitable for the growth of tea plantation,the average value of soil porosity was 51. 89%,and the porosity value of soil samples which accounted for 73. 91% of the total sample was between 50% ～ 60%,the soil porosity of bird king tea producing area is suitable for the growth of tea plantation; the capillary water holding capacity of soil is 34. 46% on average,the capillary water holding capacity of soil sample is between 30. 00% ～ 60. 00% The highest content,fine clay content is the lowest. This indicates that the soil erosion is serious in the study area,and the fine particles that have the effect of adsorption and fixation on soil nutrients are decreasing,and soil compaction and desertification appear. Overall Niaowang Tea physical properties of good soil.
