What is the most likely reason for the reduction of wheat production this year?

1 Adverse weather factors:

From mid-April, wheat gradually entered the heading and flowering stage. Judging from the meteorological factors provided by the meteorological department, there are more rainy days, relatively insufficient illumination, lower overall temperature and higher soil humidity. After rainy days, the temperature is higher, which leads to the decrease of wheat root activity, premature aging of wheat plants in different degrees, and the decline of 1000-grain weight of wheat, which seriously affects the normal filling of wheat.

2. The influence of lodging factors:

Since wheat entered the grain filling stage, it has experienced six rainy days of different degrees, and the accumulated rainfall exceeded 95 mm, which was significantly higher than that of the whole year, accompanied by different degrees of wind influence. Lodging will occur in different degrees after each rainfall, which has different effects on the number of grains per spike and 1000-grain weight of wheat. During wheat harvest, rainy weather has different effects on wheat harvest, yield and quality. Second, when wheat was heading and bulging, it was cold in late spring. I am most afraid of cold weather when the wheat is full.

3. Pests:

This year, aphids and red spiders broke out in Henan, Hebei and Shandong, the main winter wheat producing areas, which also affected the wheat yield. A friend in Suiping, Henan Province, left a message saying that it is unreasonable that more than 5,000 mu of wheat in a township has almost no harvest because of the harm of mosquitoes. Due to the small number of ears harvested, the wheat yield is low.

4. Low water use efficiency of wheat;

If wheat is affected by the weather, which leads to drought in the early stage, heading stage and filling stage, it will directly affect wheat yield. Therefore, when planting wheat, we must ensure the water supply in these three periods.

5. Sowing time:

As the saying goes: "White dew is early, cold dew is late, and autumn is the time to plant wheat." . Therefore, the sowing date of winter wheat in China is from the middle and late September to1early October 10. The sowing date is not fixed and needs to be very similar to the local climate change characteristics, especially the precipitation. If the sowing date is unreasonable, it is easy to reduce production.
