In the growing period of corn, drought and flood disasters often cause the growth and development of plants to be hindered, and the maturity period is delayed. To this end, here are some effective approaches to cooking:
Reasonable top-dressing method in corn silking stage, with 10 kg of ammonium nitrate per g area, or with 0.2% -0.3% potassium dihydrogen phosphate solution (or 3% superphosphate calcium leachate) foliar spray. If the silking period has been postponed, it can be performed 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 2-3 days earlier.
The peeling and drying stick method peels the loquat leaves when the grain reaches a normal size at the later stage of corn filling, so that the grains are exposed and the dehydration and drying thereof are promoted. In this way, generally 4-5 days ahead of the normal ripening period, than the direct harvest at the same time increase yield 6%-15%.
Whole-plant drying method If the wheat sowing period has expired, but the corn is still not fully mature, the corn can be chopped down and the yards are at the side of the field or other idle places (be careful not to heap piles) until the leaves dries up and then pulls down the ear. Drying and threshing 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.
