In the growing season of corn (especially summer corn), it is the flood-prone season, wind disaster, and flood-relief season. Every year, corn fields with different areas are affected by different degrees of damage. So, how can we resist these natural disasters in corn production?
Before the jointing of maize to tasselling, especially before the big bell stage, the male and female ear and part of the leaves had suffered locust plagues. If the unextracted leaves were not damaged and the root pods remained, they only need to be cultivated and fertilized in time. In the field management, better yields are generally obtained; maize suffers from flooding after heading, and the ability of plants to recover grows worse, which has a greater impact on yield. According to the survey, any corn that has been cut off by hail can not restore growth. If the ear section is intact, management should be strengthened in time to promote plant growth and reduce yield loss.
In July and August, the typhoon often suffered from stormy weather, which caused lodging or stemming of corn. Corn that is lodging or stem-folding before maturity should be raised in time to avoid affecting photosynthesis. If the plants just fall flat, the plants can be straightened; if it is a stem fold, several plants should be bundled together to make the plants support each other.
Relief maize is a crop that requires large amounts of water but is not tolerant. When the soil moisture exceeds 80% of field capacity, plant growth and development will be affected. In the late growth stage of maize, under high temperature and rain conditions, rhizosphere Suffocate necrosis due to lack of oxygen, resulting in a rapid decline in plant viability, immature first crop, a great impact on the yield. According to surveys, corn has generally accumulated water for 1 to 2 days before and after tasseling, and the impact on yield is not obvious. The accumulated water cuts production by 20% in 3 days, and the accumulated water reduces by 40% in 5 days. For corn that suffers from locust plague, early elimination of water in the field, reduction of soil and air humidity, and promotion of plant growth are needed. When the land can be slashed, cultivators and soils are cultivated in time to remove soil compaction, prevent corn lodging, and improve soil permeability. The roots of the plants were restored to their normal physiological activities as soon as possible; timely application of available nitrogen fertilizers accelerated the growth of the plants and reduced the loss of flood disasters.
In addition, after the corn has suffered hail and plague, it will often hinder the growth and development of the plants. If necessary, artificial ripening can be performed.
