Which month is the most suitable for sowing corn in Anhui?

Generally in August-10, the whole country is inconsistent. Corn planting is divided into spring sowing and summer sowing, mainly in the north, mainly distributed in Liaoning, Jilin, Heilongjiang and northern Hebei. Elsewhere, summer sowing is basically accompanied by spring sowing. The maturity of maize in the north is generally from September 15 to September 23, and in the south it is mostly after mid-June 10.

The suitable sowing date in southern Henan is June 65438 ~1October 65438 ~ July 26.

Harvest period of maize in Shandong province

Shandong spring corn has high yield because of its early sowing date and long growth period. In Shandong, spring corn is sown in early April and harvested at the end of August.

Harvest period of maize in Heilongjiang province

The maturity of common corn in Heilongjiang is generally around 10/day (or Mid-Autumn Festival, that is, August 15th of the lunar calendar) every year.

When corn is ripe, the harvest time of corn in different places needs to be determined according to the growth of corn and relevant agricultural experts. Early and late harvest will affect corn yield. Before corn harvest, we must do a good job in preventing rain and waterlogging, early harvest and lodging resistance to ensure a bumper harvest.

To realize late maturity and increase yield of maize, we must keep in mind "six ones";

A look: Looking at the growth characteristics of corn, the maturity of corn needs to go through three stages: milk maturity, wax maturity and complete maturity. Because corn is different from other crops, the grain is planted on the ear, which is not easy to fall off after maturity and can be ripened on the plant.

Affirmation: Set the best harvest time for corn. Maturity is the best harvest time for corn. Some farmers worry that rainy days will affect autumn harvest and delay winter wheat planting; Some farmers are more worried that their fruits will be "snatched away" by others, so they often see the phenomenon of farmers grabbing the harvest. Early harvest and late harvest all bring unnecessary losses. From the appearance characteristics, it can be seen that the middle and lower leaves of the plant have turned yellow, the basal leaves are dry, the yellow leaves in the ear are loose, the milk line of the grain disappears, and the black layer appears and hardens, showing the inherent color of the variety.

Push: Calculate the late harvest time of corn. In general, according to the normal growth of corn, the harvest period is appropriately extended by about 10 day.

Collection: collection is quick and timely. Look at the weather forecast in advance, arrange all preparations for personnel and vehicles before harvesting, and strive to complete harvesting at one time.

1. Peeling: After harvesting, do not pile up, and peel the corn with a manual timely peeling machine.

One-step drying: Because the water content of late-maturing corn is generally around 30%~40%, listen to the weather forecast, dry in sunny days and thresh and dry in time until the water content of corn is below 14%.

In the spring corn area, because it is not affected by the sowing pressure of the following crops, as long as farmers change their ideas and postpone the current harvest period by 5 ~ 15 days, the potential of corn yield increase can be tapped by 10% ~ 15%. However, in the summer corn area of Guanzhong, the corn harvest is around the National Day. If it is extended to 10 and 15, the yield can be increased by about 15%.
