There is only one earth. The ever-increasing population and food demand make efficient agricultural production more important.
The popularization of plant protection drones has greatly improved the mechanization of agricultural production management. However, at a higher level of mechanization, how to continuously improve agricultural production efficiency? Digital agriculture may become the key to problem solving.
As the degree of mechanization of "cultivation and harvesting" gradually increases, the outline of the development of digital agriculture is gradually clear. Digital agriculture uses information as an agricultural production element, and is an agricultural production method that uses modern information technology to visually express agricultural objects, the environment and the entire process, digitally analyze decision-making, and intelligently execute operations.
By operating the multi-spectral drone, we can effectively collect high-precision multi-spectral data and generate NDVI images to help agricultural monitoring and environmental monitoring work efficiently complete.
But how do you look at the NDVI diagram? Studies have found that healthy plants are greener because of their high chlorophyll content. If the health of the plant is poor, or even die, the chlorophyll content will decrease. The NDVI vegetation index uses this principle: the higher the NDVI value, the higher the chlorophyll content, and the healthier the plant.
Can NDVI images correctly reflect the growth of crops? The field application in New Zealand can give us more inspiration.
Using the NDVI vegetation index map generated by the multi-spectrum to accurately manage farmland crops-such a program is relatively mature for the New Zealand agricultural company Ferntech. I took the multi-spectral drone to an unfamiliar hop farm in Nelson, and told the story of the beer farm from another angle through NDVI images and field verification.
The first selected area is the plot with more concentrated red on the NDVI map. Red indicates that the plant vitality is low. According to the plant's growth position, the Ferntech team judged that these crops in the gap between the plant and the plant are almost struggling to survive.

Field verification is indeed the case, most of the plant leaves in this area have turned yellow and deteriorated. The reason is that the soil in this area is different from that in the surrounding area. The estate managers also said that the hops in these locations have not grown well for a long time.
