Latest Technical Key Points for Field Management of Wheat at the Jointing Stage
Wheat is a crop everyone is familiar with, and it is grown across large areas in northern China. Wheat goes through several different growth stages. Each stage has different management methods, and the jointing stage is one of them. The jointing stage is the period when wheat grows rapidly and gains height. However, many people do not know how to manage it when growing it, so we have put together the management methods for the jointing stage of wheat. Let's take a look!
1. Heat Preservation and Cold Resistance
The jointing stage of wheat generally occurs in spring, when temperatures are relatively low, and after this stage the wheat's cold resistance declines. If heat preservation and cold protection are not carried out in time, the young wheat ears will be affected to varying degrees. You can appropriately irrigate the field to raise the water temperature and enhance the soil's heat conductivity, thereby preventing the surface temperature from dropping. If frost damage has already occurred, then fertiliser and water should be applied promptly to improve the wheat's resistance, supplement nutrients, strengthen the wheat's cold resistance, and reduce the incidence of frost damage.
2. Fertiliser and Water Management
The jointing stage of wheat is when the wheat's growth vigour is at its strongest during the cultivation process. Its demand for fertiliser and water is very high, and this is also the stage when the wheat's various organs develop rapidly. Topdressing should be carried out in time, and the most important of these is jointing fertiliser, which should be applied according to the specific growth conditions of the wheat. It is usually applied when the wheat is growing its second node, but it must not be applied too early, too late, or in excessive amounts, otherwise the wheat grains will become empty and nutrient accumulation will be affected. Phosphorus and potassium fertilisers can also be applied appropriately to improve the quality and yield of the wheat.
3. Prevention and Control of Pests and Diseases
Pests and diseases are the primary problem every grower must solve, and the jointing stage of wheat is also a period of high incidence of pests and diseases, which can seriously hinder the growth and development of wheat. You should frequently observe the wheat field and make all preparations for dealing with pests and diseases. If plants with abnormal conditions are found, they should be removed promptly and the wheat field disinfected. Then check what disease it is and take corresponding control measures according to the actual disease. Special attention should be paid to the control of insect pests, precisely because insect pests can cause other diseases to occur. When spraying pesticides, be careful to spray the affected parts, and after spraying they must not come into contact with water; if they do, spray again promptly.
4. Daily Management
The daily management of wheat is very important. Weeds in the field should be removed in time, because weeds have a great impact on the growth of wheat. They not only rob the wheat of nutrients and water, but if the weeds are too tall they will also make the wheat field less permeable to light and air. Therefore, we can use an appropriate amount of herbicide or manual weeding to remove the weeds from the wheat field. It should be noted that no matter which method is used, care must be taken not to damage the roots, because damaging the roots will cause great harm to the nutrient absorption and transport of the wheat plant's root system.
The above four points are the management methods for the jointing stage of wheat cultivation. Everyone should pay attention to the prevention and control of pests and diseases, because this is the problem that poses the greatest harm to wheat growth. The main diseases of wheat include fusarium head blight and powdery mildew, and the main pests are wheat spiders and aphids. All pesticides for the prevention and control of pests and diseases should be prepared to create a good growing environment for the wheat. That is all for today's introduction.
