The observation of plant root image monitoring and analysis system shows that: after application of P fertilizer, it can promote the increase of root dry matter weight, root length, surface area and root length density, and with the increase of the application amount to promote the growth of root growth, but also reports that phosphorus Inhibition occurs when the concentration is too high or too low. Potassium deficiency could significantly inhibit cotton root extension and lateral root development, slow down the development of lateral roots, and be most sensitive to fine roots. Studies have shown that total root length and total root surface area of ​​potassium-deficient seedlings are equivalent to 35.7% of potassium treatment. ~38.0%.
Various external stress factors that adversely affect cotton growth can affect the growth of cotton roots. The root image monitoring and analysis system of the plant showed that the root length, root volume, root average diameter, root surface area, and root/shoot ratio all increased with salt stress. The above parameters were also increased with increasing salt concentration. All have different degrees of increase. In addition, with the induction of heavy metal cadmium, cadmium accumulates in the root tip cells as the concentration increases, causing damage to the cell structure.
The retention of cotton leaf branches has been a controversial issue in cotton cultivation. The growth and distribution of roots under the vegetative and normal pruning conditions were compared using the plant root image monitoring and analysis system. It was considered that the vegetative cotton roots had early growth and growth, large root growth, and a higher growth rate than normal pruned cotton. 3.2 times the normal pruning cotton, but premature aging in the late. From the above research conclusions, the leaves of the leaves can promote the development of the root system, increase the root biomass, but it is also easy to induce premature aging.

Soil is the growth and development of cotton roots directly connected to the object, so the structural characteristics of the soil can also have a certain impact on the growth of the root system. Soil nutrient status is also a major factor affecting the growth of crop roots. The moderate level of nitrogen is conducive to the accumulation of root biomass, and the root surface image monitoring and analysis system determines that the root surface area decreases with the increase of nitrogen application rate. The average nitrogen supply does not affect the root length density. When sufficient moisture increases nitrogen supply, root dry weight, root length, and root surface area are significantly reduced.
