The original method of measuring chlorophyll content is to extract chlorophyll from leaves by using organic matter. Although the extraction method of chlorophyll is simple, direct and accurate, it is also obviously restrictive: it is destructive and time consuming. The recently developed YF-YL01 Chlorophyll Meter provides an excellent opportunity to estimate chlorophyll levels quickly and non-destructively.
The use of a chlorophyll meter for chlorophyll content in plant leaves has a fast, non-destructive measurement. The results of the measurement are affected by certain factors and have certain limitations. The handheld chlorophyll meter can only be used for slightly larger leaves. Species, not yet used in small leaves, such as conifer species. In addition, it should be noted that since the range of measurement is small and the reaction is very sensitive, if the greenness level of the whole blade is to be represented, different parts of the blade are separately measured and then averaged.
It has limitations and has indelible advantages. The handheld chlorophyll meter is easy to carry and easy to measure. It can replace the direct determination of chlorophyll content in the field, especially if this method does not damage the blade, so it can also be continuous. Dynamic measurement, in some special experimental requirements, has its irreplaceable superiority and should be actively promoted in forestry research. Especially with the increase of remote sensing technology application, the chlorophyll content of ground plants will be measured by chlorophyll meter. Large application space. Judging the lack of nitrogen content can help us reduce the use of nearly 10% of nitrogen fertilizer, while the yield will not decrease and the quality of crops will continue to improve.
