Spring corn fields
The old saying, “a man makes a mistake for a year”. In spring, many of the village's older brothers began to rub their hands and prepare to grow corn. Don't rush! The temperature is not good enough. The seed goes down to die. This year, the weather is cold and hot, it's broadcast blindly and early, it's scavenging, it's scavenging, and it's possible that a year's harvest will drift. Today, let's get this straight, when will the most steady plant ever occur, so that your corn will be swiped and swirled。
The core is one: look at the temperature, don't look at the temperature
Many people in the countryside are used to reading calendars, feeling like they should grow beans, before and after being clear. This old experience may not work in today's changing climate. The sun is warm during the day, but it's still cold under the ground at night. The maize seed is sprung, and it is crucial to see soil temperatures of 5 to 10 centimetres deep, professionally known as “crop temperature”。
Seeds go down like babies to sleep, and there's a warm tumble. The heat is not enough, the seeds sleep in the soil for a long time, either rotting or being eaten by the diseased pests in the soil, which leads to a lack of seeding and failure to replant。
Remember this “gold standard”: five days in a row, five to 10 centimetres deep at temperatures above 10°c to 12°c, is the safe line for maize seeding. Under 8°c, the gestation is very slow and the risk for the rotten species increases significantly; above 35°c, it burns young buds. The ideal lumber temperature is around 25°c and the seedlings are fast and strong。

National planting schedule
Our country is large, from south to north, and the planting time cannot be “one size fits all”. Don't listen to the internet for a day. We have to combine the location of our land。
Region
Spring corn is right for the air
Key reminder
North-east region (hergila, inner mongolia)
Late april – early may
Temperature recovery is slow, the cold is protected from spring, and late-cooked varieties are cultivated in cross-border areas。
Hwang huai sea region (hebei, shandong, henan)
Late april
Catching the “cooled tail” seeding, parts of shandong could be up to early april。
North-west region (singingganing, xinjiang)
Late mid-april — early may
In arid areas, care is taken to protect the water by using the full membrane dhow。
The yangtze river basin and the south (hupe, hunan, anhu, etc.)
Late march — early april
The temperature rises fast, and the spring rains must be guarded against the stains。
We have to be flexible about our village and our land. The temperature on the slopes is high and can be broadcast several days earlier than in the back. Sands are warm but poorly watered, adhesive lands are warm but well protected and the timing of planting needs to be fine-tuned。
Farmers check the corn seedlings in the fields
Before and after the seeding, these things are in place
Picked the day, just halfway through. The details before and after seeding are managed to determine the quality of seedlings directly。
This spring, we'll watch out for the pits
In the light of this year's climate predictions and the frequent mistakes of the countryside, two particular reminders are:
First pit: blind early, bet on the weather
In the spring of 2026, the overall climate was warm but volatile, and the risk of winterization remained. Don't look at the heat in a few days and hurry to plant it. Remember: "i'd rather broadcast it three days later than one day earlier." it is much more secure to wait for the temperature to reach the standards, and to wait for them to reach them。
Second pit: neglect of indignity, dry seeding, etc
Soil moisture (sweeting) is as important as temperature at seeding. You've got your hands in a band, you've got your hands on the ground. If the ground is too dry, it is necessary to plant seeds or water them, and not to bury the seeds in “waiting rain”, which would seriously reduce the rate of seedling。

It's a couple of quick-on-the-spots
To make corn grow better, these proven earth solutions and new techniques can be tried:
Growing land is a technical exercise with god, with respect for both old experience and new science. Keep in mind the hard indicator of temperature stability of 10°c, which combines our local farm time and affection, and does not blindly follow the wind, and your corn wins on the starting line。
Next issue: how do we get the corn to grow, grow and not be bald? In the next article, let's talk about the "three-water-two-fertilizer" management of corn seeding, and make it happen, making it easy to grow 200! Remember to collect this, and pay attention to me, sowing, managing, reaping all the dry goods, so that you can grow even more
