Four key stages of corn planting
Many areas of corn cultivation have the experience of the older generation in their own place. Corn has a large planting scale in China. It can be planted on a large scale or on a large scale. Generally speaking, corn must be planted at this critical stage. Grasp it well, let's take a look at it briefly.
First, the selection
First of all, the first stage is to select seeds. Planting corn with good varieties is the key to increasing income, so it is especially important in the seed selection stage. How to choose high-quality seeds, there are several rules to follow. The first is to decide according to the local heat resources and the growth period of the corn variety. Generally, the long-term and long-term corn varieties have better yield performance and higher yield potential. When the heat is sufficient, the corn varieties with longer growth period should be selected as much as possible, so that the production potential of the excellent varieties can be maximized. However, it should not be too high a dependency, otherwise it will lead to the corn not fully mature, the corn is not full enough, and will greatly affect the taste and nutritional value of the corn.
Therefore, in addition to the above methods, it is also necessary to pay attention to local precipitation and temperature to select seeds. Generally speaking, according to experience, the amount of snowfall in the winter is small in the winter and the winter is not cold. In the second year, the rainfall will be relatively high in the summer, the accumulated temperature will not be high, and the varieties with too long growing season will not reach the growth requirements, which will affect the seeds. Normal growth. On the other hand, if there is less rainfall, you can choose a seed with a longer growth period.
Second, nursery
The second stage is the seedling stage and the seedling stage. The most important thing we need to pay attention to is to use straw to return to the field for proper treatment. After sowing, it is necessary to spray the corresponding organic pesticides in time, and at the same time, the soil temperature needs to be ensured, which can promote the development of corn roots.
Third, the heading period
The third stage is the corn heading period, when the corn just grows the ear of corn. During this time, our most important thing is to prevent pests. Our group should operate on weak diseased plants, which can help the growing corn to be infected and get more light and nutrients. Growing. In addition, at this stage, we also need to pay attention to the fact that if the rainfall is insufficient, we also need artificial irrigation to reach the water required for normal corn growth.
Fourth, flowering and fruiting period
The final stage is the flowering and fruiting period of corn. During this period, what we need to do in particular is proper fertilization. We need to carry out targeted nitrogen supplementation according to the spinning condition of the ear of the corn itself to meet the nutrients and nutrients needed for corn growth at this stage. At this time, it is also necessary to meet the water requirement, but not excessive, the corn is about to mature, and excessive moisture may cause root necrosis, so it is necessary to control the amount of water.
These are the four key periods in the corn growing stage. Let's see which stage is what you need to add. Let's communicate!
