In the vast field, the corn plant with its upright posture and golden ears, has become the outstanding crop. However, each corn plant experiences a short and challenging life journey from sowing to harvesting. So how long do corn plants live? This article will take you to explore the growth cycle of corn plants, influencing factors and ways to extend their life, and reveal the mystery of this green life.
The Growth Cycle Of Corn Plants
The growth cycle of corn is the time it takes from the beginning of sowing to the final ripening harvest. This process can be roughly divided into several stages such as germination, growth, flowering and fruiting. In general, the growth cycle of corn is between 90 and 150 days, but this is not a fixed number, and can be affected by a variety of factors.
1. Germination stage: When the seed is planted in the soil, under the appropriate temperature and humidity conditions, the seed begins to absorb water and expand, and then germination. This phase usually takes 7-10 days.
2. Growth stage: After germination, the corn plant enters the growth stage. At this time, the root system of the plant gradually expands, the leaves increase, and the stalk thickens. Under suitable growing conditions, corn plants will grow rapidly and form luxuriant colonies.
3. Flowering stage: As the plant grows, corn enters the flowering stage. At this time, the male flower order (smallpox) and the female flower order (ear) appear successively. The male flower sequence produces pollen, and the female flower sequence receives pollen and fertilizes.
4. Fruiting stage: After fertilization, the female flower sequence begins to develop into an ear, and the grains on the ear are gradually enriched. As the grain matures, the corn plant gradually ages. When the grain reaches the appropriate harvest standard, the life cycle of the corn plant is also coming to an end.
Factors Affecting The Life Of Maize Plants
The longevity of maize plants is affected by many factors, including variety characteristics, environmental conditions, cultivation management and so on.
1. Variety characteristics: Different varieties of corn have different growth characteristics and cycles. Some varieties are born to grow quickly and therefore live relatively short lives; Some varieties are slower growing and take longer to reach maturity. In addition, some varieties resistant to premature aging have stronger vitality and can extend the life of the plant.
2. Environmental conditions: Environmental factors such as light, temperature, moisture and soil fertility will directly affect the growth rate and life of corn. Under the appropriate environmental conditions, the growth cycle of maize will be relatively shortened, otherwise it will be extended. For example, corn likes a warm and sunny growing environment, it is best to receive at least 8 hours of light every day, and the optimal growth temperature is 22-30 ° C. Under these conditions, corn plants are able to grow and mature faster.
3. Cultivation and management: Reasonable cultivation and management measures are also important factors affecting the life of maize plants. Including the choice of sowing time, density control, fertilizer application and pest control and so on. These measures will affect the growth rate and life of corn to some extent. For example, reasonable dense planting can meet the needs of single plant and group plant growth and ensure the robust growth of plants. Scientific fertilization can provide sufficient nutritional support and promote the growth and development of plants. Effective pest control can reduce the damage degree of plants and extend their life.
Methods To Prolong The Life Of Corn Plants
In order to extend the life of corn plants and improve the yield and quality, we can take the following measures:
1. Selection of anti-premature aging varieties: selection of good varieties with strong anti-premature aging ability can reduce the occurrence of premature aging and extend the life of plants.
2. Crop rotation: For the same plot of land planted with corn for many years, you can change to other crops, and then plant corn in a year or two. This can effectively reduce pathogenic bacteria, improve soil nutrient deficiency, and provide a better soil environment for the growth of corn.
3. Land preparation in advance: In the case of conditions, you can carry out autumn tilting, deep tilting in advance can make the soil fine, melt, and kill some soil pathogens. This is beneficial to the growth and development of maize root system and improve the resistance of maize plant to stress.
4. Reasonable dense planting: according to the cultivated corn varieties, reasonable control of planting density. Too dense or too sparse is not conducive to plant growth and development. Reasonable dense planting can meet the needs of single plant and group plant growth and ensure the robust growth of plants.
5. Scientific fertilization: In different growth periods of corn, nitrogen, phosphorus and potassium should be rationed reasonably. Fertilizer should be applied according to the growth needs of plants and soil nutrient conditions. In the milk ripening stage of corn grouting, it is necessary to apply grain fertilizer in time, prevent fertilizer loss and premature aging, accelerate grouting and increase thousand grain weight.
6. Prevention of pests and diseases: In view of maize diseases and pests, it is necessary to prevent them in advance and take comprehensive control as the policy. The seeds that can be mixed for prevention should be mixed in advance, and the seeds that can not be mixed should be sprayed with fungicides or insecticides for prevention and control at the early stage of the disease. This can effectively reduce the damage of diseases and pests to the plant and extend its life.
Conclusion
The longevity of maize plants is a complicated and changeable problem, which is affected by many factors. By understanding these factors and taking corresponding management measures, we can better grasp the growth law of maize and improve its yield and quality. However, with global climate change and the transformation of agricultural production methods, the growing environment of corn plants is also changing. Therefore, we need to continuously strengthen scientific research and technological innovation, and explore corn planting technology and management methods that are more adaptable to the requirements of the new era. Only in this way can we ensure the sustainable development of the corn industry and make greater contributions to human food security and ecological and environmental protection.
