The standard of maize seedling is that the leaves are green and healthy, and the corn stalks are long and tough. Only when the leaves are healthy can photosynthesis be fully carried out. The long and tough stems of corn mean that they can grow into tall corn plants in the future. Want Miao Quan, Miao Qi, Miao Zhuang. We should choose good corn seed varieties from the beginning. In addition to good varieties, corn seeds themselves should be healthy, not rotten or moldy. Good seeds are the basis for the healthy growth of maize seedlings. So we must choose good seeds, which is half the battle, because good varieties of corn seeds have great advantages in growth, disease resistance and many other aspects. In addition, try to sow evenly when sowing. In this way, corn seedlings can be planted evenly. So as to receive light evenly.
Besides selecting high-quality seeds, Miao Zhuang should also pay attention to these things: pay attention to pest control, fertilization and weeding. These points are explained in detail below:
1. If the strong seedlings of corn grow well, we should pay attention to the prevention and control of pests and diseases: corn planting has a little particularity, that is, corn seeds are easily destroyed by terrestrial insects such as crickets. Therefore, before sowing corn, we should spray pesticides in the field to kill all crickets. If conditions permit, you can close the shed and kill crickets through high temperature.
2. If you want to grow well, you should pay attention to fertilization: both maize seed seedling raising and early maize seedling growth need potassium, which can promote seed metabolism and accelerate seed emergence, and potassium can activate photosynthetic enzymes, thus accelerating leaf growth. Therefore, attention should be paid to the application of potassium fertilizer in the early stage.
3. In order to grow strong seedlings in Zhang Shihao, attention should be paid to weeding: weeds in corn fields have two disadvantages, the first is to compete for nutrients in the fields, and the second is that the roots of weeds can invade the roots of corn. Therefore, weeds in corn fields can be eliminated by pulling weeds or using herbicides.
