The latest Tillering causes and Control methods of Maize

The phenomenon of tillering often occurs in maize at the seedling stage, if the tillering is not controlled in time, it will seriously affect the growth and development of maize, so what is the cause of maize tillering? How to prevent and cure it? Let's take a look.

1. Variety characteristics

Corn tillering is one of the characteristics of cereal crops, different varieties will show different tillering characteristics under the same cultivation conditions, which can not be avoided.

Control methods: before planting, we should choose varieties with weak tillering or no tillering, such as Zhengdan 958, Jundan 20 and so on, without tillering under normal conditions.

2. Drought

Drought is also one of the causes of maize tillering, in the maize growing period of serious drought, resulting in the upper part of the main stem growth obstacle, often the phenomenon of tillering.

Prevention and control methods: for drought, timely watering, keep the soil moist, promote the growth and development of corn, especially when the soil water retention is not strong, should be often watered, and in the rainy season to do a good job of drainage, so as to avoid stagnant water retting roots.

3. Planting is too dense

If the planting density is too small, it is easy to cause tillering phenomenon, which is more obvious in the varieties with strong tillering, and the tillering phenomenon will also occur if the planting density is not strong, so reasonable close planting is beneficial to control the occurrence of tillering.

Control methods: reasonable close planting, according to the characteristics of varieties, such as plant height, leaf angle, etc., to determine a reasonable population density, so as to avoid too high density resulting in field canopy or tillering caused by excessive thinning. The tillering phenomenon of corn can be removed manually by ploughing and soil cultivation, the method is to pull out the tillers first, and then carry on the middle tillage to cultivate the soil, generally in the seedling stage combined with middle tillage for high soil cultivation can effectively inhibit the tillering.

4. Disease

When corn suffers from some diseases, there will also be tillering phenomenon, for example, when suffering from downy mildew, the aboveground stem nodes of corn will grow many sterile lateral branches, the main stem is high, the stem is thin and easy to lodge, and there is no yield. The main reason for the occurrence of corn downy mildew is due to the occurrence of low temperature, overcast and rain or waterlogging during the growing period, and when the fields are closed, lack of light and poor ventilation.

Control methods: improve the conditions of drainage and irrigation in the field to avoid the occurrence of downy mildew, avoid the dead corner of shaded land or depression, change the general planting to large and small rows, maintain reasonable row spacing and determine reasonable row direction, which can effectively improve the ventilation and light transmission in the field. prevent diseases and tillers. The occurrence of downy mildew should be prevented in time to avoid the spread of the disease.

The above is the introduction of the causes and control methods of corn tillering. I hope it can help you. If you want to know more about it, please follow us.
