The latest methods to shorten the corn growth period and promote early maturity

Corn is an important economic crop in our country. During the corn planting process, if climate and human factors cause corn emergence to be delayed and the optimal growth time to be missed, this situation will cause the corn to fail to mature normally. Otherwise, once the maturity time is missed, the temperature begins to drop, and early frost will cause the phenomenon of watery corn kernels, affecting yield and quality. Below, Qinnong Network brings methods to solve this situation. Let us take a look at corn early-maturity promotion techniques.

1. Choose early-maturing varieties

Because of climate factors, the optimal sowing time may be missed, which may affect corn germination and emergence, causing some seeds to fail to germinate and emerge normally. After emergence, the seedlings are weak and uneven, and the phenomenon of dried suspended sprouts is also likely to occur. At this time, timely reseeding is needed. After reseeding, there is no doubt that harvest will be delayed, but in order to avoid yield reduction caused by low temperatures, early-maturing varieties should be selected when reseeding. According to local climate conditions, choose early-maturing corn varieties with 200-300°C less accumulated temperature than normal maturity. It is best to take sprouting measures, which can provide timely remediation.

2. Reasonable topdressing

If the optimal growth time is missed, in order to harvest at the appropriate time, fertilization must be increased to promote early maturity. When corn grows to the silking stage, apply ammonium sulfate to promote early maturity, applying 10-15k per mu, or spray foliar fertilizer to promote early maturity, using a low-concentration potassium dihydrogen phosphate solution for leaf spraying. If the silking stage is missed, the tassels of the corn can be removed in alternate rows to reduce nutrient consumption and allow nutrients to supply seed growth.

In the late grain-filling stage of corn, when the corn kernels have grown to normal size, the outer husk of the corn ear can be peeled open to expose the kernels on the ear to the air, which can speed up their moisture evaporation. Through this method, corn can generally mature 4-5 days earlier than normal corn, and at the same time yield can be increased by 6%-15%.

4. Air-dry the whole plant

Similar to the method of peeling and sunning the ears, when the temperature has already dropped after autumn and winter wheat is beginning to be sown, if the corn is still not mature, the corn can be cut down together with the stalk and neatly stacked in the field or in an open space. Note that they should not be piled together, to avoid rot and mildew, which can lead to low corn quality and, in severe cases, total crop failure. Increase ventilation, and after the leaves of the corn stalks dry up, break off the ears, expose them to the sun to dry, and then thresh. If the operation is generally correct, yield can be increased by 10%-20%.
