Ridge soil sampler

Abstract

The invention belongs to the technical field of researches of soil science and environmental science, and specifically relates to a ridge soil sampler applied to ridge planted crops. The ridge soil sampler mainly comprises a sampling head, a connection rod, a support rod, a handle and a lever, wherein one end of the lever is fixedly connected with the handle and the other end of the lever is hinged with one end of the connection rod through a pivot device; the other end of the connection rod is fixedly connected with the top end of the sampling head; one end of the support rod is fixedly connected with the handle and the other end of the support rod is fixedly connected with the sampling head; the sampling head is composed of two hollow 90-degree fan-shaped grab buckets; sampling ports are formed in the fan-shaped grab buckets; the edges of the sampling ports are shaped like waves or sawteeth; and the sampling ports of the two fan-shaped grab buckets are meshed. The ridge soil sampler is simple in structure, convenient to use, less in disturbance to crop growth and high in precision and representativeness, and is suitable for the soil sampling of ridge cultivation.

Description

technical field [0001] The invention belongs to the technical field of soil science and environmental science research, and in particular relates to a ridge soil sampler for ridge crops. Background technique [0002] Ridge farming is a farming method in which ditches are opened on the ground to form rows of soil ridges as ridges, or the soil between rows is gradually cultivated on the roots of crops to form ridges, and then crops are planted on the ridges. Nowadays, ridge cultivation is more common. In North China, Northeast China, and Inner Mongolia, it is mostly used to cultivate dryland crops such as corn, sorghum, sugar beet, and vegetables. In other areas, it is mainly used to cultivate potato crops such as tobacco, sweet potatoes, and potatoes. With the wide application of ridge cultivation, people's research on ridge effect and ridge soil is gradually in-depth, and it is necessary to take samples of ridge soil, which is also the work of ridge farm soil testing, formul...

Problems solved by technology

At present, there are basically two types of soil samplers: one is a small soil shovel, which has a simple structure, but on the one hand, it has the disadvantage of destroying the ridge body and soil structure in application, and there is a large randomness in sampling, and it is difficult to sample. Questions representing soil properties in ridges

The other is a T-shaped soil sampler, which includes fixed and convertible drill bits. Although it is convenient to use, there are also some problems in soil sampling for ridge farming: 1. The amount of single sampling is small, and multiple sampling at multiple points is usually required. Low working efficiency; 2. In sandy soil, the soil sample taken in the drill bit is easy to slip, and it is difficult to get a complete sample; 3. The sampling volume is small and the representativeness of the sample taken is poor, which affects the ridge body sampling test accuracy of results
