Methods of shortening the growth period of Maize and promoting its early maturity

Corn is an important economic crop in China. In the process of corn planting, if the emergence of maize seedlings is delayed and misses the best growth time due to climate and human factors, this situation will lead to the normal maturity of corn. Otherwise, if you miss the ripening time and the temperature begins to drop, it will appear in the early frost, affecting the yield and quality. Below, the pro-agricultural network brings a solution to this situation. Let's take a look at the corn technology to promote precocity.

1. Select early-maturing varieties

Due to climatic factors, missing the best sowing time may affect the germination and emergence of maize, resulting in some seeds can not germinate normally, weak seedlings are uneven after emergence, and it is easy to hang dry buds. At this time, it is necessary to replant in time, and there is no doubt that replanting will lead to delayed harvest, but in order to avoid the problem of yield reduction caused by low temperature, early-maturing varieties should be selected when replanting. According to the local climate, early-maturing corn varieties with an accumulated temperature of 200-300 ℃ lower than normal maturity should be selected, and the best budding measures can be remedied in time.

2. Reasonable topdressing

Missed the best growth time, in order to harvest in time, it is necessary to increase fertilization to promote early maturity, in the corn growth to the silking stage, the application of ammonium sulfate to promote early maturity, 10-15k per mu, or by spraying foliar fertilizer can promote early maturity. spraying fertilizer with low concentration of potassium dihydrogen phosphate solution leaves. If the silking period is missed, the male ears of corn can be removed in interlaced rows, reducing the consumption of nutrients and allowing nutrients to supply the growth of seeds.

3. Peeling and tanning stick

In the late filling stage of corn, when the corn grain has grown to the normal size, the outer bract of the corn cob can be peeled off, so that the grain on the corn cob can be exposed and exposed to the air, which can speed up its water evaporation. This method can generally mature 4-5 days earlier than normal corn, while increasing the yield by 6% and 15%.

4. Drying the whole plant

Similar to the method of peeling and drying sticks, it has cooled down after autumn, and when you begin to sow winter wheat, the corn is still not ripe. At this time, the corn connecting rod can be cut down, and the neat code can be put out in the field or free. What should be noted is not to pile up together, so as to avoid corruption and mildew, resulting in low quality of corn and no harvest in serious cases. Strengthen ventilation, wait for the leaves of the corn stalk to dry, and then break off the ear, sun-dry and then thresh. If the general operation is correct, the yield can be increased by 10% and 20%.

The above is the pro-agricultural network to shorten the growth period of corn to promote its precocious methods, hope to help you, want to know more corn planting knowledge, please pay attention to the pro-agricultural network.
