技术领域technical field
本发明具体涉及一种原状草地样品取样装置。The invention specifically relates to an undisturbed grassland sample sampling device.
背景技术Background technique
土壤和植物取样是植物生理、生态学研究的重要步骤，原状土壤和植被进行室内条件控制的研究方法也是研究实践中常用的手段。目前基于原状土壤的取样技术比较成熟，但无法满足原状土壤-植被整体的野外取样，进而进行室内条件的控制实验。现有的原状土壤技术主要有如下缺点：Soil and plant sampling is an important step in the study of plant physiology and ecology, and the research method of indoor condition control of undisturbed soil and vegetation is also a commonly used method in research practice. At present, the sampling technology based on undisturbed soil is relatively mature, but it cannot satisfy the field sampling of undisturbed soil-vegetation as a whole, and then conduct control experiments under indoor conditions. The existing undisturbed soil technology mainly has the following disadvantages:
1、忽视植被：仅注重土壤部分,依附于其生存的植物被忽视。而二者共存研究往往是科学院研究的重点。1. Neglect of vegetation: only pay attention to the soil part, and the plants attached to it are ignored. The coexistence of the two is often the research focus of the Academy of Sciences.
2、用途单一：2. Single use:
2.1、只用于测定容重等物理指标，样品难以进行其他更有价值的利用导致收益率较低；2.1. It is only used to measure physical indicators such as bulk density, and it is difficult to make other more valuable uses of samples, resulting in low yield;
2.2、无法实现土壤和植被响应人造环境中的研究。2.2. Research on soil and vegetation responses in man-made environments cannot be realized.
3、结构单一：通常是不同体积的圆柱体或者立方体，无法实现多种形状的转换。3. Single structure: usually cylinders or cubes of different volumes, which cannot be transformed into various shapes.
