The reason for the emergence of purple seedlings in corn lies not only in the lack of fertilizer but also in the root system.

The purple-red seedling of corn basically occurs in the seedling stage and can disappear gradually at the time of 7-8 leaves. The plants with purple seedlings usually grow weakly and the plants are weak. For this situation, the scientific development of agriculture can be summarized as the lack of phosphorus in the field! This is the most common situation, but there are other problems, which will be explained one by one.

First of all, for the problem of phosphorus deficiency, it will cause insufficient nutrition supply, hindered development and slow growth during the growth period of the plant. The phosphorus in the body will gradually decrease with the growth of the plant, and the plant will show a reddish color. Today, farmers in many places do not take ploughing for the field when planting, and supplement phosphate fertilizer to the field, so there is a lot of phosphorus deficiency in the maize seedling stage. This is also the most common situation in agricultural production.

However, the scientific development of agriculture should remind everyone that this is not the only factor. Under the condition of stagnant water in the field, the poor transport of mineral ions in the roots of maize plants will also lead to the phenomenon of purplish red plants.

In a similar situation, the above situation will also occur when the roots are damaged by insect pests, drug damage, continuous cropping and so on.

For the purplish red situation of corn seedling stage, we can also see that, like the reasons mentioned above, it is not a very serious problem, but the damage to the plant is more serious, which also shows that the maize seedling stage is indeed very fragile. Special attention should be paid to the details of maize seedling management.

For the purplish red problem of corn seedling stage, scientific agriculture also put forward some views, understand the cause of the problem, farmers can be targeted when there is a problem to give symptomatic treatment, for the seedling stage, supplement phosphate fertilizer at the time of cultivated land, at the same time do a good job of seed coating treatment, at the same time strengthen the management of diseases and insect pests in the seedling stage can avoid the above situation.
