Can corn be pollinated when it rains when it blooms?

It rains during flowering, so corn can't pollinate.

If it rains and pollinates, it will affect the activity of pollen, and corn pollen will swell and rupture due to excessive water absorption, which will reduce the quality of fertilization. When the amount of loose pollen in the male ear decreases, the pollination of the female ear is limited, or if it is not pollinated, it will automatically age, resulting in the lack of grains at the top and poor seed setting rate. When the humidity is high in rainy days, corn pests and diseases are easy to occur and spread, which leads to weak growth potential of corn plants and affects flowering and pollination. So it is impossible to pollinate corn when it rains during flowering. When corn is artificially pollinated, we should pay attention to check the weather forecast and choose a sunny morning to avoid rainy weather.

The flowering and pollination of maize are closely related to temperature and humidity. It is observed that when the temperature is lower than 18 degrees or higher than 38 degrees, the male flowers can't open, but when the temperature is about 25 degrees and the relative humidity in the air is about 30%, the pollen can open faster.

Matters needing attention in maize pollination

1, 5-7 days after emasculation, the female ear begins to spin silk, which lasts about 5-7 days, and pollination is best within 2-5 days after corn spinning, at which time the pollination rate is high.

2. Pollination time is finally selected at 8- 1 1 on sunny days. There should be no dew in the fields at this time. If it is too early, dew will affect pollination.

3. It is not suitable for pollination when the temperature is higher than 35 degrees.

4. It is best to harvest the pollen now, and then harvest it after harvesting, so as to avoid collecting too much pollen at one time, causing accumulation and pollen death and affecting pollination.

5, corn pollination period should pay attention to adequate fertilizer and water, flood control and drought resistance, prevention and control of corn borer, aphids, etc.
