Field rice root system sampling device and method

Abstract

The invention discloses a field rice root system sampling device and a sampling method. The movable cutting plate is quickly assembled into a square sampling barrel with the lower edge as a cutting edge along the slot in the U-shaped cutting plate; a first pedal plate is fixed at the upper end of the U-shaped cutting plate; a second pedal plate is fixed at the upper end of the movable cutting plate; the square sampling barrel can be stepped into soil by stepping on the first pedal plate or the second pedal plate, the T-shaped handle is fixed to the outer side of the upper edge of the long edgeof the sampling barrel, the height of the T-shaped handle is adjusted by changing the position of the plug pin, the soil penetration direction of the sampling barrel is conveniently controlled, and root layers of different depths are separated by the sample cutting plate along the sample cutting groove in the U-shaped cutting plate. By applying the field rice root system sampling device, the taken-out square-column-shaped soil body containing the rice root system is cleaned and stored after being cut in a layered mode, the actual growth characteristics of different parts of the rice root system can be accurately known by observing and researching the root systems of the different parts, and therefore the efficiency and precision of root system research are improved.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a field rice root system sampling device and a sampling method. Background technique [0002] The root system provides support for the growth of plants. It is not only the absorption organ of nutrients and water, but also the place where many substances are synthesized, assimilated or transformed. The growth of the root system directly affects the growth and development, nutritional level and yield level of the whole plant. Plant roots are deep underground, and there are many difficulties in observation and research. Therefore, reasonable sampling devices and methods are particularly important for the study of root systems in the field. [0003] At present, the root system of rice in the field is usually directly excavated for sampling. This method cannot completely obtain the root system of the lower layer. It is difficult to achieve the same sampling specificatio...
