How to do corn late

If the silking period has been postponed, it can be passed through by intervening males to reduce the consumption of nutrients, increase the temperature of the leaves, and accelerate the growth process; generally, the silking period can be advanced by 2 to 3 days.

2. Peeling and drying stick method In the late stage of corn filling, when the grain reaches normal size, the loquat leaves are peeled off to expose the grains and promote dehydration and drying. In this way, generally can be 4 to 5 days earlier than the normal ripening period, than the direct harvest at the same time increased yield 6% to 15%.

3. Whole plant drying method If the wheat sowing date has arrived, but the corn is still not fully mature, the corn connecting rods can be cut down, coded at the field side or in other idle places (be careful not to heap piles) until the leaves dry and then smashed. Drying and threshing of the lower ear generally increase the grain weight by about 20%.

In addition, during the corn filling period, the hoe (or plough) is used to plow (or plow) on both sides of the ridge; or in the milk ripening period, it is sprayed with a long-805 oil booster 500 times, which also has the advantage of ripening. effect.
