The Latest Methods and Precautions for Corn Detasseling
Managing corn at the tasseling stage affects its yield, and at this time there is a technique that can increase yield, namely detasseling. Many people wonder whether corn detasseling really can increase yield. In fact, according to practical production evidence, detasseling can increase yield by 5%-8%. So how should corn be detasseled? What should be noted when detasseling? Let's take a look together.
1. Timing of detasseling
When the tassel has emerged 6-7cm above the top leaf and has not yet shed pollen, this is the best time to detassel it, and the yield-increasing effect is also more obvious. This is because the stalk of the tassel is relatively crisp and tender, and the stem node part of the tassel is not firmly attached, making it easy to pull out. If you wait until it has grown and developed for a period of time, the stalk ages and the stem node becomes firmly attached; detasseling at this time is not only difficult to pull out, but the top leaf is also very easily pulled off along with it, and the stalk is also easily broken. Not only will the detasseling effect not be achieved, but yield will also be affected. Detasseling should be done on a sunny day, but the time of strong light should be avoided, so the best time is generally in the afternoon or afternoon, during a period when it is sunny but not too intense. In this way the temperature is suitable, and the wound after detasseling heals easily, avoiding infection by pathogens. Never detassel on rainy days, so as to avoid water soaking into the ear and causing rot and death.
2. Detasseling methods
When detasseling, you must also master the method and not proceed blindly, otherwise it will have the opposite effect. Generally, detasseling is carried out on alternate rows or alternate plants, removing the tassels that have not yet opened and shed pollen, so that normal pollination between plants will not be affected. Corn has many tassels and produces a lot of pollen. The pollen is mainly spread by wind, and the respiration of the pollen is extremely strong, consuming a large amount of the plant's nutrients and competing with the ear for nutrients, which is bad for corn growth. Therefore, removing part of the tassels will not only not affect corn growth, but can also avoid unnecessary nutrient consumption. After the plant has completed pollination, all the tassels can be cut off to reduce nutrient consumption, so that the plant's nutrients are concentrated in supplying the ear, enabling it to grow and develop rapidly and increasing yield.
3. Precautions for detasseling
When detasseling, be careful not to cut off the plant's leaves, otherwise it will affect the corn's photosynthesis, reducing the nutrients the corn synthesizes, and then reducing yield, so that the goal of increasing yield cannot be achieved. In addition, pay attention to the timing of detasseling and detassel in time. If detasseling is too late, the yield-increasing effect will not be obvious. Detasseling should be done on alternate rows or alternate plants; do not detassel every plant. Also, do not remove the tassels at the edges and ends of the field.
