Detailed Explanation of Key Field Management Techniques for Sorghum
Sorghum is relatively rare in the south, but in the north it is one of the most basic food crops, and sorghum cultivation is one of the largest grain crops by planting area in northern China. China has a very long history of growing sorghum, and the cultivation techniques are quite well established. However, certain field management techniques are still required during the growing process, so today we bring 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 tasks 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 method is usually used for cultivation. 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. Also, because sorghum plants are relatively tall, when the sorghum reaches the trumpet 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 sorghum is at the seedling stage, its nutrient absorption capacity is very weak, and it simply cannot compete with the weeds. So we should appropriately spray herbicides at the seedling stage, spraying thoroughly and evenly, and pay attention to the concentration of the herbicide to prevent it from also inhibiting seedling growth.
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 during the sorghum's regreening stage. If no fertilizer was applied, then appropriate topdressing should be done 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 supplementation, promoting sorghum growth and increasing yield.
4. Disease Control
Disease control is work that must be done well during every growth stage of sorghum, and management of the sorghum field should be strengthened. Regularly observe the growth conditions of the sorghum, 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 borers, and if these are not managed in time, they may lead to a total loss of the sorghum harvest. 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. Growing sorghum is very common, but not many people have completely correct cultivation methods. Everyone should pay extra attention to the harm caused by pests and diseases.
