Description
Technical field
The present invention relates to cotton fibers to detect correlative technology field, and specially a kind of fiber for cotton plot experiment is long
Spend detection method.
Background technique
Currently, it is varied to restrict the factor that Cotton in China industry further develops in a healthy way, is summed up, mainly has following
Two aspects: on the one hand, cotton inefficiencies, large labor intensity are planted in Huanghuai Area cotton region；On the other hand, all the time due to China
Output of cotton is placed above the other things, it is low relative to external some countries to cause cotton quality, therefore cause " state cotton storage, outside
Cotton is entered the market " difficult situation.It can satisfy the cotton variety that high-quality, disease-resistant, pest-resistant, high yield and the suitable for machine of the market demand are adopted
It is fewer and fewer.Cotton Industry will be from the single development track devoted exclusive attention to output and take into account yield to emphasis quality, in recent years, our hospital
Cotton seminar complies with cotton demand for development, from initiative the feeling free to try all to cultivation mode of cotton Parental Germplasms resource
Tightened around cotton quality raising and carry out, achieve a large amount of high-quality germ plasm resource and valuable experience, cotton
Quality includes a series of indexs such as suede length, intensity, mic value, uniformity, elongation, spinning evenness index, and cotton section
Grind that personnel are most intuitively also most readily by that tool and experience obtain is the long data of suede, it is cotton scientific research personnel's breeding Gao Pin
The first step of matter cotton variety (being).
The long data of cotton waste it is accurate whether, be related to the retention of a kind (being), while being also related to the work in later period
Measure, the expenditure of working efficiency and scientific research cost, therefore, find it is a kind of accurate, quickly, efficiently the long method of measurement suede for
It is most important for scientific research personnel.
Summary of the invention
It is above-mentioned to solve the purpose of the present invention is to provide a kind of fibre length detection method for cotton plot experiment
The long detection method of the cotton waste mentioned in background technique is complicated, detection accuracy inaccuracy, and the problem that detection efficiency is low.
To achieve the above object, the invention provides the following technical scheme: a kind of fibre length for cotton plot experiment
Detection method includes the following steps:
S1, sampling: cotton enters the blow-of-cottons later period, from the experimental plot of cotton variety to be detected (being), is in using 5 point samplings
