In addition, the utility model also provides a rice root system sampling method, including root system sample and root system washing, its step is as follows:

firstly, determining a rice plant to be sampled, carrying out label recording on the rice to be sampled and removing the overground part of the rice to be sampled; after investigating the ground characteristics of continuous 12 rice plants in the field, 4 rice plants close to the average value are selected as samples for later sampling according to tillering or other characteristic indexes, and the ground parts are cut off.

Secondly, sampling the root system of the rice to be sampled together with soil through a sampler, and cutting the samples into a plurality of groups according to the depth from the ground surface for later-stage experiments;

thirdly, putting the sampled sample into a heat-resistant plastic bag, then weighing the sample in the heat-resistant plastic bag, grinding the sample by hands when a large soil block still exists in the sample, ensuring that the root hair is not damaged as much as possible in the process, and then putting the heat-resistant plastic bag with the sample into a first container;

fourthly, according to the weight ratio of the sample to the water of 10: 3 (for example, 150ml of water is added into 500g of sample), boiling water with the temperature of 90-100 ℃ is added into the sample in the heat-resistant plastic bag, then the heat-resistant plastic bag is sealed, and the water inside and the sample are mixed uniformly by shaking;

fifthly, heating the sample mixture in the first heat-resistant plastic bag of the container until the mixture is viscous, stopping heating, and then cooling to normal temperature; taking the weight of the sample mixture in the heat-resistant plastic bag as an example of 500g, adjusting the sample mixture to 500w of fire power by using a microwave oven, and heating for 2 minutes to obtain a viscous mixed solution; the soil blocks adhered to the root hairs can be peeled off by the step and uniformly mixed into the water, and the soil and the rice root hairs are separated at the moment.

The sample can be exploded and splashed in the process of heating by a microwave oven, but the packaging of the heat-resistant plastic bag can ensure that the roots of the rice can not splash to the outside of the heat-resistant plastic bag when the sample is exploded and splashed, thereby ensuring the accuracy of the sample at the later stage.

Sixthly, pouring the viscous mixed liquid sample cooled to the normal temperature into the filter screen I, and washing the viscous mixed liquid sample with clean water for multiple times until soil is removed; the first filter screen is of a double-layer filter structure, the inner diameter of the meshes of the filter screen on the upper layer is 0.2mm, the inner diameter of the meshes of the filter screen on the lower layer is 1.5-2mm, and a spacing gap is arranged between the two layers. The arrangement of the double-layer filtering structure can ensure that some tiny roots can not be washed away by water, and the accuracy of later-stage experimental data is further ensured.

Seventhly, after the treatment of the sixth step, the residual substances in the first filter screen are basically sand and stone particles, root hairs and organic humus and grass seeds. Pouring all the residual substances in the filter screen I into a container II filled with clear water, stirring to fully separate heavy substances from light substances, standing for a period of time to stratify the substances, removing sediments (sand and stone particles) at the lower layer, adding clear water into the residual upper substances again to perform stratified cleaning, and repeating the step for 2-3 times; after this step, some sand and stone particles and heavier material are substantially removed, leaving only a small amount of humus in the sample.

Eighthly, placing the sample processed in the step seven into a screen mesh for sliding screening processing, thereby separating thick root hairs and fine root hairs.
