Due to the failure to timely sow or suffer from natural disasters such as drought and flood in the early stage of childbirth, it affects the growth and development of plants and delays the maturity period. In order to timely harvest, the method of promoting ripening can be adopted to shorten the growth period and achieve the goal of early or timely harvest. . There are many kinds of ripening methods, which can be selected according to specific conditions. 1. Appropriate top-dressing method: During corn silking stage, 10 kg of ammonium nitrate is used for chasing after each acre, or 0.2-0.3% of potassium dihydrogen phosphate solution (or 3% of superphosphate calcium leaching solution) is used for foliar spraying. . 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 speed up the birth process; generally, the silking period can be advanced 2-3 days. 2, peeling sun stick method: In the late corn filling, when the grain reaches the normal size, the loquat leaves will be peeled off, so that the grain exposed, promote its dehydration and drying. In this way, it can generally be 4-5 days earlier than the normal ripening period, and the yield can be increased by 6-15% directly than at the same time. 3, the whole plant drying method: If the wheat sowing period has arrived, but the corn is still not fully mature, you can cut the corn stalks, yards in the field or other idle place (be careful not to pile heap) until the leaves dry The dry and threshing of the underarm ear can generally increase the grain weight by about 20%. In addition, in the corn filling period, the hoe (or plough) is used to pound (or plow) on both sides of the ridge; or in the milk ripening period, the long-805 oil booster 500 times solution is used for the foliar spraying, which also promotes Cooked effect.
