Problems solved by technology

[0004] At present, when conducting research on the underground parts of peanuts, one method is to use potted plants or tube plants. However, this method is not only time-consuming and laborious, but also limits the growth of the underground parts of peanuts, resulting in inconsistent growth of peanut root systems and root nodules with the natural state in the field. , leading to underrepresentation of the research results
Another way is to directly excavate the underground part. However, this method is time-consuming, labor-intensive and heavy, and it is easy to cause the difference in the sampling range of the underground part due to the inconsistent excavation area and volume of the root zone, which affects the accuracy of the research results.
In addition, when conducting research on plant root systems, soil drilling is usually used to extract roots, but peanuts are taproot plants, and four rows of lateral roots grow from the main root, which are arranged in an obvious "ten" shape. The number of roots in the area where the cross lines intersect is small. When the soil drilling sampling method is used to collect peanut roots, the position of the drill is different, resulting in different root volumes for each drill, which affects the uniformity of the research results.
If in order to improve the uniformity of sampling, it is necessary to increase the number of sampling points, resulting in increased workload, time-consuming and labor-intensive

Embodiment 1

[0050] Example 1: Research on underground parts of peanuts planted in the field

[0051] Field trials will be carried out in Pingdu City, Shandong Province from May 2021 to September 2021. Peanuts are planted with ridges and covered with film, one ridge and two rows, and the water and pest control are the same as the local conventional production. The tested peanut varieties include: Qinghua No. 7 (common type), Qinghua No. 6 (pearl bean type), Sizihong (multi-grain type) and Qixialong peanut (longsheng type), each 500m 2 .

[0052] 1) Develop a sampling plan

[0053] Avoid two rows of peanuts on the side, and select 10 representative plants for each variety by using the "far and near observation" method.

[0054] 2) Selection of representative plants

[0055] Far view: avoid the headlands and side rows, place yourself in the field of each variety area, observe the peanut plants about 2 to 5 meters away from you, and select the area with uniform plant growth, normal leaf c...

Abstract

The invention discloses an accurate and efficient peanut underground part sampling method, which is based on long-term test observation and on the basis of defining peanut underground part growth and field distribution characteristics in a natural state. The links of making a sampling scheme, carefully selecting representative plants, mastering the sampling opportunity, positioning the sampling range, optimizing sample-soil separation, removing abnormal plants, filling in sampling records, storing samples in a classified mode and the like are provided, accurate and efficient sampling of the peanut underground part in the natural growth state is achieved, and the defects of an existing method are overcome. And the influence of the natural environment on the sampling representativeness is effectively reduced or avoided.

Description

technical field [0001] The invention belongs to the technical field of agricultural research, and in particular relates to a method for sampling underground parts of peanuts, in particular to a method for one-time accurate and efficient sampling of underground parts of peanuts on the basis of maintaining the natural growth state of peanuts in the field. Background technique [0002] The underground part of plants is the main organ for plants to absorb water and nutrients, and it is also the key part that contacts nutrients in the soil. Its growth and development directly affects the growth and yield of aboveground parts of crops, and is often regarded as a key area of ​​plant physiology research. [0003] Peanuts are rare crops that bloom on the ground and bear fruit underground, and there are root nodules on the root system, and the pods and root nodules are all located in the underground. With the expansion of peanut planting area, relevant researches on peanut pod develop...
