Will corn production be reduced this year?

Analysis on factors of maize yield reduction;

Under basically the same management conditions, the same agricultural fertilizer, chemical fertilizer and seeds as in previous years, the important factor affecting corn yield this year is the weather. However, the climatic conditions in Liaoning province from spring to now are not conducive to the development and maturity of corn crops.

1, the influence of spring climate on crops has been unstable since the beginning of spring, with low temperature. Taking Tieling as an example, the daily average temperature hovered between 5-7℃ in early April, which was about 1℃ lower than that in previous years. The time when the ground temperature was over 8℃ on April 23rd was later than that on April 2nd 1 1 day.

By mid-May, the daily average temperature was lower than 10℃, which made the daily average temperature pass 10℃ stably, 20 days later than normal, close to the cold climate index in late spring. Frequent rainfall this year has caused a lot of soil moisture. In April this year, the rainfall in Tieling City reached 47-89 mm, and the soil moisture content remained above 20%, the largest in history.

2. The influence of summer climate on crops in Liaoning main producing areas has been low, especially the rainy weather since June. From June to September, the temperature in Liaoning is about 0.5- 1 degree lower than the normal temperature all the year round, and the obvious low temperature period appears in the critical period of corn growth and development, which has a substantial impact on corn yield.
