Why doesn't the wheat go to ear? Can you still fix it?

Wheat farmers all know that heading date is the most important stage of wheat production. Generally speaking, the heading period of winter wheat is about 40 days, and whether the management methods of heading diseases and fertile weeds are effective or not determines the amount of wheat production. However, many farmers have also found that wheat does not produce ears at the heading stage, so why does the wheat not produce ears? Can it be saved? Next, let's have a look.

First, why does the wheat not come out of the ear? 1. After the wheat turns green, it will quickly enter a stage of rapid growth and development. Especially from heading to booting stage, it is the key period of wheat node extension, leaf flexion and extension and young spike differentiation, and the temperature at this moment is very critical. In all normal conditions, the temperature is not less than 16 degrees, wheat booting will be normal. If at this stage, the local encountered continuous cooling, precipitation and air temperature, for example, when the temperature is less than 6 degrees for a long time, the young panicle can not differentiate normally, and it will not be able to heading normally afterwards. 2. If the varieties are different, their characteristics are also different. Some varieties have good disease resistance, but not lodging; some have good cold resistance, but will have poor disease resistance; some are not cold-resistant, but other resistance is good, if the cold resistance of the variety itself is very weak, encounter the often said temperature reduction, booting can not be carried out, it will cause no heading to appear. Naturally, if you choose and buy razor seeds that are not suitable for local planting or buy fake ones, you will not be able to produce ears.

Second, can the wheat without heading be saved? Whether wheat can be saved without heading mainly depends on the total area of non-heading. If a wheat field, only a small part of the unheading, the share of less than 30%, can be sprayed with potassium dihydrogen phosphate brassine boron fertilizer to reduce, to promote the growth and development of wheat, increase the grain weight of heading wheat, in addition, we also need to do a good job of "one spray and three prevention" countermeasures to minimize damage. If the total area of non-heading in a wheat field is too large, and most of the field shows no heading, then destroy the field as soon as possible, and then rotate spring crops, such as spring corn, spring soybeans, spring peanuts or other crops, to reduce losses. In general, the vast majority of wheat can be seen in mid-April whether it is heading or not, and this stage is also the sowing time of spring crops without delay.

Above is the reason that the wheat does not produce the ear and the preventive measures, the reason that the wheat does not heading is mainly caused by the reduction of temperature and the variety, the situation of the production of the small total area, the key consideration is the variety factor, the large-scale production condition, the key consideration is the temperature factor.
