Early frost poses a greater threat to crops. When the dew point temperature is below 2 degrees Celsius at 9:00 pm, frost will generally occur in the early morning of the next day. Prepare and take measures:
1, timely stop pole skin drying
In the later stage of drying corn wax, 15-20 days of drying, the moisture content can be reduced by 14% -18%, early maturity of 5-7 days, can increase corn production by 5%. This measure can accelerate dehydration, mature earlier, escape the frost period and improve quality. Suede drying time is very strong, it is necessary to seize the opportunity, neither too early nor too late, prematurely affect the grouting, reduce production, lose the significance of drying too late, the best time to dry the skin is wax in the late stage.
2, knock out the bottom of the corn, remove the small rods and invalid spikes
Pull out the false plants and concentrate the limited nutrients to normal plants. The late-mature leaves at the bottom of the corn are aging and brown and have lost their function. They must be promptly knocked down, increase the ventilation and light transmission in the field, reduce disease infestation and reduce nutrient consumption, and increase output and quality. Remove the ear with no effect, spikelets or panicles, reduce the consumption of water and nutrients to ensure that the main panicles are full and increase yield.
3, timely and late
The postharvest corn is strong, and there are still some nutrients in the plant body after harvesting. Therefore, the harvest time must be timely and late. Before the harvest, pay attention to the weather forecast, cut the corn 2 days before the next frost, and concentrate it into a “shop†for post-cooking to increase the yield and quality of corn. Generally, it can increase the grain weight by about 20%.
