A kind of method for testing the top soil force of seed germination

Abstract

The invention relates to the field of seed science, especially to a seed germination soil-jacking force detection technology. The technology provided by the invention comprises processes of seed germination work, soil-jacking force detector arrangement work, software control measurement work, postprocessing and the like. By the use of a germination box, a seed placement plate and a flat substrate, seeds undergo standard germination to generate soil-jacking force; a soil-jacking force detector is connected to a computer, and a force plate of the soil-jacking force detector is scientifically arranged on the germination box and senses soil-jacking force information by means of a pressure sensor; through the computer, a data acquisition software is started to realize soil-jacking force detection control so as to obtain soil-jacking force detection data; and after storage and analysis of the detection data, the software is exited, the soil-jacking force detector is turned off, and postprocessing such as uninstalling of the force plate and the like is finished to complete the detection task. Based on characteristics of seed germination for generation of soil-jacking force, a mechanical sensing technology is adopted to raise detection efficiency and guarantee data accuracy, and seed vigor is effectively evaluated through soil-jacking force detection results. The technology provided by the invention can be widely applied in seed vigor detection.

Description

technical field [0001] The invention relates to the field of seed science, in particular to a method for detecting soil force of seed germination top. Background technique [0002] Seeds are the most basic means of production, and their quality is directly related to the abundance of agricultural production. Seed vigor is a general term that determines the potential ability of a seed to emerge quickly and neatly and to grow into a normal seedling under a wide range of field conditions. It is an important indicator of seed quality and a main component of seed value. It is closely related to seed emergence in the field, and some people even regard seed vigor as a synonym for seed quality. The quality of seeds determines the level of field yield and has an important impact on agricultural production. Therefore, it is very important to do a good job in seed quality evaluation, especially the rapid detection technology of main crop seed vigor is worthy of further study. Accord...

Problems solved by technology

Traditional seed germination top soil strength testing methods have disadvantages such as poor equipment, large errors, and inconvenient operation. They can only measure the average value of the seed population, but cannot measure the germination top soil strength of each seed, and are rarely used.
