The leaf area index can be used to reflect the growth status of the crop, and its change reflects the different conditions of the growth and development of corn, which is of great significance. It is not difficult to find through the leaf area meter determination test that, regardless of the ultra-high-yield species (Xianyu 335, Zhengdan 958) or common varieties (Great Wall 799, Tongji 100), the leaf area per plant of maize is consistent with the growth period. As the growth continues to increase, the leaf area increases rapidly after entering the jointing stage, reaches its maximum value during flowering, and then gradually decreases. The increase in the leaf area of ​​super-high-yielding and common-cultivated varieties is different, manifesting as Zhengdan 958> Xianyu 335> Great Wall 799> Tongji 100. The leaf area index of super-high-yield corn and normal corn changed greatly. From the start of jointing, the gap between Zhengdan 958 and Xianyu 335 and Tongji 100 leaf area index began to be significantly different, and the difference in leaf area with the decrease of leaf area at maturity was different. Still exist. The leaf area index of the two ultra-high product species is on average about 1.2 higher than that of the common variety.
In the early stages of plant growth, the assimilation activities of several leaves are very important. Therefore, during the cultivation process, the traditional Chinese medicine should allow the first three leaves to appear as much as possible, and the leaf area should be as large as possible to ensure the subsequent growth and development of the plant. Through the leaf area meter to determine the leaf area of ​​the plant and comprehensive analysis of the relevant parameters of yield, we can find that the yield of the crop increases with the increase of the leaf area index.
Leaf area analyzer analysis of relationship between leaf area index and yield
The important role of the leaves is that it has been recognized that, in the case of corn growth production, 90% of the dry matter in the grain is a photosynthetic product that is dependent on the photosynthesis of the leaves. The assimilation function of the blade has a very close relationship with the size of the blade. Therefore, it is necessary to understand the growth pattern of the leaves in order to improve the high yield of corn. In other words, the leaf size is the leaf area. At present, the determination of the leaf area can generally be measured using a leaf area meter.
