Can 37 degree corn be pollinated?

Corn cannot be pollinated at 37℃. During the flowering and pollination period of maize, the temperature is generally 25 ~ 27℃, the weather is sunny and breezy, and the relative humidity of the air is about 70%, which is beneficial to flowering and pollination. In case of high temperature and drought, filaments are easy to wither and pollen life is easy to lose, which leads to poor pollination and yield reduction of corn. In addition, rainy weather and low temperature will also hinder the spread of anther pollen. Therefore, corn planting must be sown in time. Only timely sowing is the basic premise to obtain higher yield and benefit.

In spring maize producing areas, temperature is an important factor affecting sowing date. It is generally believed that when the soil temperature is lower than 8℃; Seed germination is slow, seedling vigor is weak, emergence is irregular, and diseases and insect pests are serious. When the temperature of seedbed reaches 8℃ ~ 12℃ for at least 5 days, sowing can be started, which is a suitable sowing date for maize, and it will have adverse effects on maize too early or too late. In the years and regions with poor soil moisture and long drought time, irrigation should be carried out in time, and the sowing date can also be adjusted to avoid seasonal drought in the key period of corn growth and development, such as 15 days before heading to 15 days after heading. The medium and early maturing varieties are suitable for a long sowing date, and the sowing date can be reasonably selected according to the actual production situation.

In addition, in areas with two or more crops a year, stubble arrangement should be considered during sowing. For example, in the southwest of Shandong Province, the sowing date of winter wheat is about 65438+ 10/~ 65438+10, so corn should be 65438+ 10. ?
