Problems solved by technology

In this case, when using soil drilling to extract soil, because the soil below the plow layer has not been turned for many years, the soil is very compact, and manual operation is strong and inflexible, which is very laborious and time-consuming. Moreover, due to the slippery soil, errors are prone to occur.
If a power drill is used, the cost is high (power drill and fuel)
Sampling paddy fields with a shovel is even less feasible

Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings and given embodiments.

[0014] refer to figure 1 , This device for vertical sampling of saline-alkali soil in paddy fields consists of a cylindrical barrel 1, a barrel cover 2, a metal drop 3, a soil-borrowing hole 4 and a rubber plug 5.

[0015] Before use, mark the scale on the inner wall of the bucket. The scale size is set according to the purpose. The size of the soil borrow hole should be designed according to the diameter of the short-stem soil drill and the rubber plug.

[0016] When inlaying, inlay the vertical sampling device in the sampling plot. The inlay point should be in a place with flat terrain and easy access. It is best to inlay before irrigation to facilitate digging operations. The size of the pit should be strictly in accordance with the size of the barrel. If the cylindrical barrel is too large, it will be easily floated after being inlaid. If it ...

Abstract

The invention relates to a device for paddy field saline-alkali soil vertical sampling. The device is composed of a cylinder barrel, a barrel cover, a metal pendant, soil taking holes, rubber plugs and a short rod soil auger, and is characterized by simple structure, and low material cost. During use, the sampling barrel is inlaid in a paddy field, and in the barrel, sampling by the short soil auger is simple and convenient. The sampling barrel can be placed in the field for continuous use for a long time, and the sampling error can be reduced. The invention can also be applied in paddy field growing season and wetland soil sampling. Specifically, the invention can be used for analysis of paddy field or wetland vertical gradient of saline ion migration, nutrient distribution rule, root distribution and microorganism distribution and the like of soil sample collection. The device provided in the invention has the advantages of simple structure, low cost, convenient installation, small sampling error, easy mastery by operators, and wide application range, etc., and has a promotion value.

Description

technical field [0001] The invention relates to a device for taking soil samples from a vertical section of paddy field saline-alkali land, belonging to the field of soil science. Background technique [0002] At present, soil sampling in the growing season of paddy fields often adopts the soil auger used in dry fields to obtain soil, and the tubular soil auger is drilled into the soil layer of required depth during operation. When the soil auger is taken out, the upper layer of water flows away, and the remaining moist soil is put into the utensil, which is a relatively common sampling method. The more traditional method is to dig the soil with a shovel, which is very difficult to operate due to the presence of water, and it will damage the seedlings. When studying the dynamics of salinity in paddy field saline-alkali soil, due to leaching and evaporation, the change of salinity in saline-alkali soil is more obvious in the vertical direction, and the salinity in the vertic...
