Latest Key Technical Points for Sorghum Field Management

Sorghum is relatively rare in the south, but in the north it is a basic food crop, and sorghum cultivation is one of the food crops with the largest planting area in northern China. China has a very long history of sorghum cultivation, and the cultivation techniques are quite well established. However, certain field management techniques are still required during cultivation, so today the editor brings you the field management methods for sorghum. Let's take a look below!

1. Intertillage and earthing up

Although intertillage and earthing up are essential work in cultivation, many people do not know the purpose of intertillage and earthing up. Regardless of what crop was previously grown in the soil, the planting-hole cultivation method is usually used. Therefore, the work of intertillage and earthing up is very important, and we should carry it out appropriately according to the actual growth conditions of the sorghum. Generally, immediately after the sorghum survives transplanting, a deep intertillage should be carried out once to improve soil permeability, enhance fertility, and promote nutrient absorption by the sorghum roots. In addition, because sorghum plants are relatively tall, when the sorghum reaches the funnel stage, earthing up should be done in time to prevent lodging caused by excessive height, which would affect yield.

2. Reasonable weeding

Weeds will certainly appear in sorghum fields, and when there are too many weeds in the field, we must weed in time. Many people ignore the presence of weeds, allowing them to grow unchecked, robbing the sorghum of nutrients and water, which hinders sorghum growth and causes nutrient deficiency. Especially when the sorghum is at the seedling stage, its nutrient absorption capacity is very weak, and it simply cannot compete with the weeds. Therefore, we should appropriately spray herbicide at the seedling stage, spraying thoroughly and evenly, and pay attention to the concentration of the herbicide to prevent it from also inhibiting the growth of the seedlings.

3. Timely topdressing

Topdressing is an indispensable management task in sorghum cultivation, as sorghum growth requires relatively large amounts of nutrients. When topdressing, we should determine the amount based on the growth conditions of the sorghum, the variety, and various other factors. If sufficient fertilizer was applied when the seedlings were transplanted, then no topdressing is needed at the greening stage of the sorghum. If no fertilizer was applied, then appropriate topdressing is needed according to the nutrient situation. Control the proportion of each nutrient in the fertilizer well, so that the sorghum's nutrition is more comprehensive and it receives sufficient replenishment, promoting sorghum growth and increasing yield.

4. Disease prevention and control

Disease prevention and control is work that must be done well at every growth stage of sorghum, and management of the sorghum field should be strengthened. Observe the growth conditions of the sorghum regularly, and promptly remove diseased plants when disease symptoms are found. Do a good job of sorghum prevention work, improve the disease resistance of sorghum, and regularly spray the field comprehensively to prevent and control pests and diseases. Common sorghum pests and diseases include smut, aphids, and peach fruit borers; if these pests and diseases are not managed in time, they may lead to total crop failure of the sorghum. For farmers, this not only wastes a whole year but also causes them to lose everything, so everyone must pay attention.

The above is a brief introduction to sorghum field management. Planting sorghum is very common, but not many people have completely correct planting methods. Everyone should pay special attention to the harm caused by pests and diseases.
