A course on the latest techniques and methods of promoting early ripening in Maize

In order to ensure that the corn matures as soon as possible before the autumn frost and take precautions in advance, many farmers will promote the early maturity of corn artificially, although many people will use this method to promote the early maturity of corn, but their practices are also different. The following editor also brings you a way to promote early ripening of corn, let's take a look.

1. Better irrigation

As the saying goes, "drought in spring is not drought, but half is lost in autumn." in September, many areas are prone to drought and insufficient water supply, seriously affecting the process of grain filling, reducing grain number and grain weight, resulting in a direct reduction in yield. Watering should be carried out at the end of corn milk ripening, that is, 7-10 days before harvest, and the amount of water should not be too large to prevent plant lodging. If there is heavy rain, it is necessary to clear the ditch in time after the rain to remove stagnant water so as not to soak the roots in the field.

2. Early removal of empty stalks and diseased plants

The conditions should be checked frequently after booting, and it must be found that there are empty stalks and diseased plants, which need to be cut off thoroughly as soon as possible. in addition, the cleared head smut plants should be taken out of the field and buried deeply to prevent the pathogen from spreading again in the field. This can also improve the permeability of the field, reduce the consumption of nutrients, contribute to the growth and development of plants, and promote the formation of large panicles and full grains.

3. Spraying micro-fertilizer

In recent years, the first frost period has obviously moved back, but if the sowing is delayed and the growth time of corn is limited, it will still be damaged by frost. Measures such as releasing autumn ridges, spraying potassium dihydrogen phosphate, breaking sticks and bottom leaves can be taken in the corn filling period in mid-late August to improve field permeability, reduce nutrient consumption and promote early maturity and high yield of corn.

4. Appropriate late harvest

At the end of corn wax ripening, remember to hit the leaves and cut the top, you can take the pole peeling to dry, speed up the grain dehydration rate, promote early maturity, and improve the corn quality, which can reduce the moisture content by 3% and increase the corn yield by 5%. When the corn bracts are dry and loose, the grain hardens and shines, the milk line disappears, and there is a black layer at the base, which should be harvested in time. At the same time, we should always pay attention to climate change, cut down corn straw 1-2 days before early frost, harvest with ears, and promote post-ripening.
