When do spring corn plants usually mature
Spring corn generally matures in late August. However, because the climate varies from region to region, the maturity time also differs. For example, in Northeast China it generally matures from early October to late October, in southern regions it generally matures in early July, and in Hunan it generally matures in early to mid-August.
Key points for sowing spring corn:
1. Spring sowing time
Corn seeds begin to germinate at 6-7 degrees, but germination is slow and the seeds are highly susceptible to damage from pathogens and pests, so sowing generally begins when the soil temperature at a depth of 5-8 cm reaches 8-10 degrees. Spring temperatures rise quickly, and the optimal sowing window is only about 10-15 days, so sowing must be done at the right time. Sowing too late may cause the seedlings to stay green and mature late, and they may suffer yield loss when they encounter low temperatures. In most regions, corn is sown from mid-to-late April to early-to-mid May.
2. Sowing depth
When sowing, pay attention to the sowing depth. Whether sowing by hand or by machine, the sowing depth should be between 3-5 cm. If the soil moisture is good, the sowing depth only needs to be 3 cm. If sown too deep, the seedlings will emerge slowly, and because they use up a large amount of nutrients to emerge, they will be weak, so the sowing depth must be well controlled.
3. Water in time
After sowing, water appropriately. After watering, water must not remain in large amounts on the soil surface. Overwatering easily creates standing water in the field, which causes seedlings to emerge slowly, and after emergence the seedlings may also turn yellow; in severe cases, it can cause a large number of missing seedlings. Therefore, watering must be appropriate; avoid heavy irrigation, and do not apply too much water at one time. Keeping the soil moist is enough. If rainy weather occurs after sowing but before emergence, drainage measures should be taken to avoid standing water in the field.
4. Uniform sowing
When sowing, sow evenly and consistently to avoid uneven emergence in each row. Some rows may grow sparsely, wasting the plot, while other rows may grow densely, with seedlings competing with each other for water and nutrients and growing thin and weak. Therefore, sowing must be uniform, with appropriate dense planting without wasting land resources, to ensure that the seedlings grow strong.
The above is an introduction to the maturity time of spring corn. I hope it is helpful to everyone.
