What to Do When Sorghum Lodges? A Detailed Guide to Field Remedial Measures

Sorghum is an annual herbaceous plant of the grass family. Sorghum is mainly used for brewing liquor, and in fact in many regions it is also processed into sorghum rice. Of course, it can also be used to make noodles, alcohol, sugar and more. It is rich in protein, amino acids and other trace elements. Moreover, sorghum has extremely strong resistance and is suitable for cultivation in various parts of our country. When cultivating it, what should be done if sorghum lodges? Let us analyze it together below.

1. Causes

There are many causes of lodging in sorghum, so when we solve the problem we need to consider the root cause of its lodging and then make a decision. First, the row spacing and plant spacing at planting time are not reasonable; being too dense or too sparse may both lead to lodging in sorghum. Second, the planting site was chosen incorrectly, and third, field management was not handled well. Finally, there is external wind force. These are all causes of lodging in sorghum.

2. Symptoms

The symptoms that appear when sorghum lodges will also differ slightly depending on the different causes of lodging. If the lodging phenomenon is caused by insufficient nutrients, the sorghum is generally on the thin and small side, and both stems and leaves will show yellowing. If the planting density is unscientific, then we can see it with the naked eye, so timely protective preparations must be made. If the soil was chosen improperly, then it will show right after planting, with a very slow growth rate, and the sorghum stems are very thin. Finally, when strong winds come, if the wind force is relatively strong, then its lodging is relatively regular.

3. Prevention and Control Methods

The prevention and control methods for sorghum lodging caused by different reasons also differ. Generally speaking, if the land was chosen improperly, then we need to use soil and fertilizer improvement methods to achieve conditions suitable for sorghum growth. If the planting density is unreasonable, then we can appropriately prune away some branches and leaves to maintain good ventilation and light transmission, or plan the density reasonably before planting. In addition, after planting, water and fertilizer must be reasonably controlled, which can enhance the resistance of sorghum plants and thereby avoid lodging.

4. Impact on Sorghum

Sorghum itself has fairly good resistance, and it is also very easy to grow; it only needs a little management, and the yield is also very good. However, lodging during the process of growing sorghum has a relatively large impact on sorghum, and the losses caused at different growth stages are also different. Sorghum rarely lodges at the seedling stage, so there is almost no impact; if lodging occurs at the jointing stage of sorghum, then it will affect the growth condition of sorghum and prolong the growth cycle of sorghum, or even result in no harvest at all; if lodging occurs after sorghum heads, then it will seriously affect the yield and quality of sorghum.

The above is all the content that the editor wants to share with everyone today. From the causes of sorghum lodging and the symptoms of lodging, we briefly understand the solutions and prevention work for sorghum lodging, and hope it can help everyone.
