Description
技术领域 technical field
本发明涉及一种测量农田作物根系分布情况或地下原装土壤的植物根系采样器，适用于灌溉质量评价、灌溉科学研究及环境保护等领域。The invention relates to a plant root system sampler for measuring the distribution of farmland crop roots or underground original soil, which is suitable for the fields of irrigation quality evaluation, irrigation scientific research, environmental protection and the like.
背景技术 Background technique
监测作物根系在土壤中的生长情况以及土壤中养分的吸收状况是作物高效用水研究中的重要环节，准确的测量作物根系的分布状况及肥料水分的含量是评估作物水肥吸收效果的重要指标，对研究不同的灌溉和施肥方法具有重要意义。Monitoring the growth of crop roots in the soil and the absorption of nutrients in the soil is an important link in the research of efficient water use by crops. Accurately measuring the distribution of crop roots and the moisture content of fertilizers is an important indicator for evaluating the effect of crop water and fertilizer absorption. It is important to study different irrigation and fertilization methods.
目前测量根系生长及分布状况的方法和设备有将根挖出来冲洗进行测量、扫描或者利用根系生长监测系统。土壤水分采用土钻取土或者挖剖面取原装土。目前取根测定根系生长方法之一是将根挖出然后利用水流进行冲洗。然后将所取根带回实验室进行测量。这种方法测量精度较高，但耗费人力物力，而且对测量根系周围影响较大，很可能破坏其它根系，还有在取根时有可能破坏掉根在不同区域的分布。测定根系生长状况方法之二安装根系生长监测系统。该方法自动化程度高，利用数码拍照可连续观测根系生长状况。这种方法设备投资大，安装位置固定，不能按照要求任意变换。Current methods and equipment for measuring root growth and distribution include digging out the roots and washing them for measurement, scanning, or using a root growth monitoring system. Soil moisture is obtained by soil drilling or digging a profile to obtain the original soil. One of the methods of taking roots to determine root growth is to dig out the roots and then rinse them with water. The removed roots were then taken back to the laboratory for measurements. This method has high measurement accuracy, but it consumes manpower and material resources, and has a great impact on the measurement around the root system, which is likely to damage other root systems, and may destroy the distribution of roots in different regions when taking roots. The second method of determining root growth status is to install a root growth monitoring system. The method has a high degree of automation, and the growth status of the root system can be continuously observed by using digital photography. This method requires a large investment in equipment, and the installation position is fixed, which cannot be changed arbitrarily according to requirements.
