Technical Field

The invention relates to the field of seed science, in particular to a seed germination soil jacking force monitoring technical device and a use method thereof.

Background

Throughout the entire growth period of the seeds, from seed germination to generation of new generation seeds, there is a constant concomitant action of various biological forces. The biological material signals are collected and utilized, so that the germination and growth rules of the seeds can be better understood, and a basis is provided for the research of related mechanisms. In Zhoudeman (1984), when the seeds germinate, there is a force that pushes the sprouts upward, and this force is referred to as germination capacity. In addition, according to the introduction of relevant contents in books such as the principle and method for measuring seed vigor (the introduction of the face, etc., 2006), the handbook for measuring seed vigor edited and published by the international seed inspection society, the handbook for measuring seed vigor edited and published by AOSA, and the like, and in combination with the previous research results, all the biological forces for promoting the tissue organ enlargement and the elongation growth of seedlings in the seed germination are collectively called as the seed germination force. It includes 4 kinds of biological force types, such as swelling force, germination force and seedling morphogenetic force. Wherein, in the germination stage, the seeds grow by the elongation of tissues and organs (such as root system, bud axis and coleoptile) and finally break through the soil layer to complete the emergence of seedlings, and the form of the biological power breaking through the soil layer is called as the topsoil power, which is an important form of the germination power. Based on previous research reports and previous test results, the seeds with high activity in seed germination have strong soil jacking force and high emergence rate; the seeds with low vigor have weak top soil force and can not normally emerge and even rot in soil. Therefore, the vigor of the seeds can be evaluated by comparing the germination and soil jacking force indexes of the seeds.

Based on a biological force sensing technology, more work is carried out on the aspect of measuring and evaluating the biological force of the seeds, and particularly certain progress is made on the aspect of monitoring and evaluating the germination soil jacking force of the seeds, including 2 patent authorizations (a corn seed germination soil jacking force measuring method 2014107631438; a seed germination soil jacking force detecting method 2014107945793) and the like, related work is also recognized and paid attention by the same lines, but some key technical problems still exist in the technical popularization and application, and need to be solved: the existing equipment lacks control over key factors of a seed germination environment; secondly, different plant seeds germinate in different soil-bearing forms, and the germination soil-bearing forms mainly comprise two types: the first type is cotyledon soil-retention type plants represented by corn, wherein the soil-retention type plants complete the soil jacking force signal acquisition and subsequent analysis work (which is solved earlier) through the elongation of a mesocotyl, the emergence of coleoptile and the contact of a coleoptile tip and a sensor probe; the second type is a cotyledon soil-out type plant represented by cotton, cotyledons are pushed out of the soil surface through elongation and bending of an embryonic axis and an embryo, and the soil jacking force measurement of seed germination of the cotyledon soil-out type plant relates to a series of problems of large soil jacking surface, effective contact between a tissue organ + a solid matrix and a sensor probe and the like, and directly influences the monitoring implementation effect of the soil jacking force and the correct evaluation of related indexes. Aiming at the existing main problems, the control of environmental factors of seed germination is enhanced, such as: temperature, illumination and the like, continuously improve and develop a flexible contact sensor unit suitable for monitoring the germination soil jacking force of cotyledon remaining (yielding) soil type seeds, and are very important for upgrading seed germination soil jacking force monitoring technical equipment and developing matched technical popularization and application.

The target data extraction and analysis operation comprises the steps of opening a target storage file (containing information of soil jacking force of different channels at different time points and the like), selecting proper evaluation indexes and models to analyze and evaluate seed vitality and the like according to different crop seeds, and storing and printing analysis results.

In summary, the invention is based on the acting characteristics of the germination soil jacking force of the cotyledon soil-left (out) type seeds and the control of the key environmental factors of the seed germination, and is based on the biological force sensing technology, a seed germination soil jacking force monitoring technical device and a use method thereof can control the key environmental factors of the seed germination, and realize the real-time monitoring, quantitative storage and the like of the germination soil jacking force signals of the cotyledon soil-left (out) type seeds.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and although the present invention is described in detail with reference to the embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made on the technical solutions implemented by the present invention without departing from the design spirit and scope of the present invention, which should be covered by the claims of the present invention.
