Remedies for corn lodging
Generally speaking, the types of plant heights, plots with excessive planting density, plots with prosperous seedlings, plots with excessive nitrogen, phosphorus and potassium, plots with stem rot and corn borer damage, and low-lying plots. In water plots, corn generally has tall plants, thin stalks, and underdeveloped root systems. It is prone to lodging to varying degrees when encountering strong winds and heavy rains.
Regarding the treatment of corn lodging, some people say that it needs to be straightened, and some say that it does not need to be straightened, because each person's remedy method is different, and the later yield will also be very different. Moreover, many people have caused secondary damages such as damaged roots, broken roots, broken stalks, and secondary lodging to corn due to improper remedial methods, which will often further aggravate the loss.
So, what is the most effective and reasonable remedy for corn after falling down?
1. Timely drainage and drainage
When corn falls under strong winds and heavy rainfall, there will be a large amount of accumulated water in the ground, and the humidity will be completely saturated. However, corn is a crop species that is neither drought-tolerant nor waterlogging-tolerant. When the soil moisture is greater than 80%, it will When there is stunted reproductive growth, corn will suffocate and die when it is soaked in stagnant water for more than 3 days.
Therefore, after the concentrated precipitation stops, the first thing to do is to drain the waterlogging in the field to reduce the soil moisture.
2. Foliar spray fertilizer to supplement nutrition
After the corn falls, the stalks, branches and leaves fall to the ground, which will greatly reduce the photosynthesis of the leaves. At the same time, the root moisture in the soil is too high to absorb nutrients and the ability to absorb nutrients is greatly reduced. Therefore, quick-acting foliar fertilizers should be applied in time to supplement nutrients. After the weather gets better, spray the foliage with 0.3-0.4 urea + 0.3 potassium dihydrogen phosphate solution, spray once every 7 days, spray 2-3 times continuously to promote early maturity of corn.
3. The key question: Does it need to be straightened manually?
After the corn falls, whether it needs to be straightened or not, it should be flexibly determined according to the lodging situation.
1. Mild lodging corn treatment: For those corn that is lightly lodging or semi-lodging, do not straighten it, especially for lodging corn before the booting stage, so as not to damage the roots and affect the growth and development. , And even cause secondary lodging, it can be restored upright naturally after spraying foliar fertilizer.
2. Treatment of severely lodging corn: For those corn that is severely lodging or completely slumped to the ground, it should be straightened manually in time, or the ears should be lifted off the ground with wooden sticks to prevent mildew, and it can be done on the same day. Lodging and straightening on the same day, do not straighten the corn for 3 days or more, so as not to cause corn root damage, broken roots or stalk breakage again.
Correct operation method: When performing manual straightening, the methods of multi-person coordination, tying and tying the roots, and cultivating soil at the roots should be adopted. One person uprights the plant and one person mixes the soil. The number of tying trees is 3-5 as one, and the number of tying handles should not exceed 5. The tying should be tight and solid, and the height of the soil should be 7-10 cm, and use after cultivating the soil. Step on the foot firmly to prevent it from loosening and falling down again.
3. Treatment of broken stalk corn: For a small amount of broken stalks, the corn should be cleared out of the field in time to prevent plant rot-induced diseases, insects and fungi, and adversely affect the normal recovery and growth of other plants; for large-scale occurrences Corn fields with broken stalks, after clearing the broken trees, can supplement crops with a shorter growth period to increase income, such as growing cabbage and radishes.
4. Preventing diseases after lodging: Corn is prone to brown spot, leaf spot and other diseases after lodging, so when the disease is found, you can spray 300 times 75% chlorothalonil, 500 times 50% carbendazim, 800 times 70% thiophanate methyl and other drugs for prevention and treatment 2-3 times, spray once every 7-10 days.
