Poinsettia is loved by the majority of people in China. It has been cultivated from south to north in China. Poinsettia is generally planted in the spring and summer season, and is listed in autumn and winter. The National Day, Christmas, and Spring Festival consume a lot. There are also many methods used in daily experiments. The applications of equation regression method, leaf area detector method, etc. are more common in practice. The application of leaf area detector can also calculate appearance indicators such as loquat leaf area, plant fullness, total leaf area index and loquat leaf area index, which can provide basis for quality control and assessment.
The cultivation of poinsettia in China is mostly in greenhouses, greenhouses, etc., and there are various cultivation and management methods. Leaf area is used as a function of growth period (determined by accumulated temperature) as a function of the leaf area detector method, or the leaf dry weight is multiplied by the specific leaf area SLA to obtain leaves. The area does not apply, but the number of side shoots to simulate the leaf area is only applicable to specific sites, specific seasons, and specific cultivation modes.
In the leaf area tester, leaf paper weighing method and regression equation method were respectively used to establish and test the leaf area calculation model of poinsettia, in order to explore a method for rapid determination of the leaf area of ​​poinsettia without causing damage to the plant. To provide the basis for the future research on the biological characteristics and growth and development of Poinsettia, the promotion of cultivation technology research, quality rating evaluation.
Using the regression equation method, the leaf area can be calculated simply by measuring the leaf length and leaf width of the representative sample. This method has the advantages of convenient operation and quick operation, no need for expensive instrumentation such as leaf area detector, no training, and strong operability. This method is applicable to both green and temporal leaves. Using this method can not only easily know the existing green leaf area, can be combined with photosynthesis model, convenient, accurate and quick calculation of dry matter production.
