How to increase corn yield? An introduction to the latest planting methods
Corn is one of the food crops with a relatively large planting area in our country, and it is also a major cash crop in our country. Our country's history of corn cultivation is also very long. But after growing corn for so long, there has always been one problem that all growers want to solve, and that is corn yield. Many times, corn yield is often not high, and farmers' economic benefits are not particularly good either. So how can corn yield be increased? Let's take a look below!
1. Soil fertilization
Veteran growers who grow corn all know that when planting corn, a second tilling treatment is generally carried out, in order to turn out all the roots of the crops planted the previous year. This prevents them from affecting the normal growth, development, and germination of corn seeds when planting corn. When tilling the soil, pay attention to whether the soil nutrients are insufficient. If there are not enough nutrients, then appropriate farmyard manure needs to be added to the soil. It is best to use some poultry manure. Animal manure has the advantage of relatively good nutrients because poultry have weak digestive capacity, so after poultry eat, a large amount of the food's nutrients has not been digested and will still be excreted with the manure.
2. Soil disinfection
Everyone also knows that corn is not suitable for continuous cropping, so before planting corn, pay attention to disinfecting the soil. Because other crops from the previous season will inevitably breed some pathogens and parasites in the soil, such as sheath blight and cutworms. Many diseases are common among crops. Everyone thinks sheath blight is spread by insects in the field as a medium, but they are all wrong. Most cases of sheath blight are caused by residual pathogens in the soil invading corn. Cutworms are a pest everyone is very familiar with. They gnaw on the roots of corn and then cause the corn to die. So after tilling the land, everyone must use quicklime or potassium permanganate to carry out a comprehensive disinfection of the soil. Everyone needs to note that when disinfecting the soil, be sure to avoid the rainy season, because rainwater will wash away all the potassium permanganate and quicklime, so soil disinfection will not have any effect.
3. Seed selection
If you want corn to achieve a high-yield effect, whether the seeds are correctly selected has a very important impact on the survival rate. Everyone may often find during the planting process that before the seeds have sprouted, or just as they have sprouted, they are already unable to grow and die. The root cause of dead seedlings is that there are insect eggs inside the seeds, and seeds free of disease and insect eggs were not selected, or the seeds were not disinfected. This phenomenon can be compared with pea planting: once the seeds begin to sprout, the insect eggs inside will gradually wake up and then begin to harm the seed seedlings. So in order to reduce or avoid this situation, we must disinfect corn seeds. The seeds can be soaked in a potassium permanganate solution for about one day, which can effectively kill the insect eggs inside the seeds.
The three methods above are the basic ways to increase corn yield. To increase corn yield, you not only need to have a correct management method, but also need patience. Whether corn has a high yield is determined at the time of seed selection. Perhaps the three methods compiled by the editor are only suitable for some growers, but after all, measures should be adapted to local conditions, and each place has different management methods.
