There are many reasons for the occurrence of red seedlings in maize, mainly caused by the following four reasons: First, phosphorus deficiency. When the phosphorus in the soil cannot meet the growth needs of corn seedlings, the phosphorus content in the seedling will gradually decrease, and the leaves will turn red or purple from dark green. The second is the accumulation of water in the fields. If the soil moisture is high, it will affect the roots' respiration, and the growth of the roots will be hindered, which will lead to malnutrition and redness and purple in the plants. The third is the harm of underground pests. The roots of the seedlings were bitten by underground pests, and their ability to absorb water and attract fertilizers became weaker, resulting in weaker seedlings and the formation of red seedlings. The fourth is caused by other reasons. If the seeding is too deep or too shallow, if the seedlings caused by improper fertilization or improper treatment of pesticides cause poisoning of seedlings, it will lead to corn red seedlings.
For the above reasons, the following measures can be taken to prevent and control: Early application of phosphate fertilizer, mainly fast-acting phosphate fertilizer, per acre can be applied to calcium phosphate 10 to 15 kg, can also be combined with pest control spraying 1% of superphosphate calcium leachate; Land, digging drains, so that the rain stopped drying, the field is not water.
