The growth period of corn is in the summer and autumn, the climate is changeable, the rain is more, and it is vulnerable to climate disasters. Yang Yinfu, an associate researcher at the Agricultural College of Northwest A&F University, said that after the disaster, measures should be taken to remedy and minimize losses.
Hail disaster
During the period from the jointing of the corn to the tasseling, the male and female ears and some of the leaves have been subjected to locust disasters. As long as the unextracted leaves are not damaged and the roots are left, the field management measures such as cultivating and fertilizing can be adopted, and a good harvest can still be obtained. If the corn is subjected to disasters after heading, the ability of the plants to restore growth will be poor, which will have a great impact on the yield. If the ear sections are intact, management should be strengthened in time to promote plant growth and reduce yield loss.
Windy Disaster
During the summer and autumn, there are often violent storms, causing corn to fall or stems. Corn that has fallen or stems before maturity should be raised in time to avoid back pressure and affect photosynthesis. For the inverted corn, if it is only rooted, the plant can be righted up. If it is a stem, the several plants should be bundled together to support the plants.
Flood Disaster
Corn is also afraid of water and requires a large amount of water. However, when the soil moisture exceeds 80% of the field water holding capacity, the growth and development of the plant is affected, especially in the seedling stage. In the late growth stage of corn, under the condition of high temperature and rain, the root system often suffers from necrosis due to lack of oxygen, which has a great influence on the yield. For corn that has suffered from flooding, it is necessary to eliminate the accumulated water in the field, reduce the soil and air humidity, and promote the plant to resume growth. When it can normally go down the field, timely cultivating and cultivating the soil to break the knot, prevent lodging, and improve soil permeability. The roots of the plants should be restored to normal physiological activities as soon as possible, and the quick-acting nitrogen fertilizer should be added in time to accelerate the growth of the plants and reduce the losses caused by the disasters.
