How to manage wheat during the grain-filling stage? A detailed explanation of the latest key points
The grain-filling stage of wheat has a very large impact on wheat yield and quality, and it is the most critical link in the wheat planting process. So how should wheat be managed during the grain-filling stage? Below, the editor will share with you the management techniques for the wheat grain-filling stage. Let's take a look.
1. Timely and appropriate irrigation
Good irrigation at the grain-filling stage is conducive to further increasing wheat yield. If irrigation is improper, it will not only fail to increase yield, but will instead lead to reduced yield and waste of water resources. Irrigation should be done timely and appropriately according to the growth of the wheat seedlings and field soil moisture, especially in wheat fields with lighter soil texture, to prevent the wheat seedlings from being affected by drought and thus affecting the grain-filling effect. When irrigating, attention should also be paid to avoiding windy weather and wheat lodging. Irrigate well with the wheat-yellowing water to promote full grains. When irrigating, note that it should not be done at noon in high-temperature and dry weather, so as to avoid wheat finishing grain filling early and reducing yield.
2. Disease control
The main diseases during the wheat grain-filling stage include rust, powdery mildew, bacterial leaf streak, etc. Pesticides such as triadimefon, diniconazole, and propiconazole can be selected for spraying control. Spray 1-2 times according to the severity of the disease, once every 7-10 days, with a maximum of 2 sprays, so as to avoid pesticide damage or pesticide residues, which are detrimental to wheat growth and human health.
3. Prevent dry hot wind and premature aging
During the grain-filling stage, the root absorption capacity of wheat is in summer, so at this time it is necessary to improve leaf retention to maintain growth, so as to avoid premature aging. At the same time, it is necessary to reduce the impact of dry hot wind on it, ensure normal grain filling of wheat, and make the grains full. When spraying disease-prevention pesticides, potassium dihydrogen phosphate and brassin can be added and sprayed together, but attention should be paid to the spraying time. It must be done in the morning and evening when soil moisture is good, and the concentration of the pesticide solution should not be too high, so as to avoid burning the leaves and causing reduced yield. Any foliar fertilizer and pesticide should be stopped 20 days before harvest to ensure that the wheat is pollution-free.
4. Timely harvest
When 95% of the wheat has entered the yellow-ripe stage, it can be harvested. During harvest, prevent rain exposure, which may cause a decline in wheat quality, ensure that every grain is returned to the granary, and achieve a bumper harvest. For multiple-cropping wheat fields, in addition to timely harvest, the wheat straw should also be promptly pulled out of the field to provide space for re-sowing, so as not to delay the sowing time.
The above is an introduction to the key points of wheat management during the grain-filling stage. I hope it can help you. If you want to learn more related knowledge, please stay tuned to us.
