What to Do When Sorghum Lodges? The Latest Remedial Methods
Sorghum is an annual herbaceous plant of the grass family. Sorghum is mainly used for brewing liquor, but 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 so on. It is rich in protein, amino acids, and other trace elements. Moreover, sorghum has extremely strong resistance and is suitable for cultivation throughout 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 sorghum lodging, so when solving the problem we need to consider the causes of its lodging at the root, and then make a decision. First of all, the row spacing and plant spacing at planting were not reasonable, being too dense or too sparse, and either of these may cause sorghum lodging. Secondly, the wrong land was chosen for planting, and there is also the matter of field management not being handled well. Finally, there is external wind force. These are all causes of sorghum lodging.
2. Symptoms
The symptoms that appear when sorghum lodges will also show slight differences depending on the different causes of its lodging. If the sorghum lodging phenomenon is caused by insufficient nutrients, it is generally rather thin and small, and both the 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 selection is improper, then it will show right after planting, with a very slow growth rate, and the sorghum stalks will be very thin. Finally, when strong wind comes, if the wind force is relatively strong, then its lodging will be relatively regular.
3. Prevention and Control Methods
The prevention and control methods for sorghum lodging caused by different reasons are also different. Generally speaking, if the land selection is improper, 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 reasonably plan the density before planting. In addition, after planting, water and fertilizer should be reasonably controlled, which can enhance the resistance of the sorghum plants and thereby avoid lodging.
4. Effects 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. Lodging during the process of growing sorghum also has a relatively large effect on sorghum, and the losses caused at different growth stages are also different. Lodging rarely occurs at the seedling stage of sorghum, so there is almost no effect; if lodging occurs at the jointing stage of sorghum, then it will affect the growth of the sorghum and prolong the sorghum growth cycle, or even result in no harvest at all; if lodging occurs after sorghum heads out, then it will seriously affect the yield and quality of the sorghum.
The above is all the content that the editor wants to share with everyone today. We have briefly learned about the solutions and preventive work when sorghum lodges, respectively from the causes of sorghum lodging and the symptoms of lodging, hoping it can help everyone.
