After discussing the impact of corn planting density on yield in the previous article, let's now talk about the impact of corn planting density on quality.
The quality of corn is directly related to the plumpness, protein content, starch content, fat content, and other factors of corn kernels, and corn with high nutrient content is better. The planting density of maize plants is directly related to the overall yield of maize, and at the same time, planting density also affects the quality of maize. It is necessary to select high-yield and high-quality corn seeds for planting in combination with climatic conditions, geographical factors, and other reasons, calculate the mathematical relationship and scale model between corn yield and nutrient content and choose the most appropriate planting plan. Make corn more nutritious.
1. Effects on corn moisture content
The moisture content of corn kernels and the dehydration rate of corn kernels are important testing indicators for corn quality sampling testing after corn is harvested. Most corn needs to be stored in warehouses after harvesting. Corn with lower moisture content is more stable and easier to store. Therefore, the lower the moisture content of corn, the better its quality and the higher the purchase price. When corn plants are planted at a lower density, the photosynthesis efficiency of the corn plants is higher, which results in more water content in the corn kernels, while in areas with higher planting densities, the corn kernels have lower water content and overall quality. better. After the corn is harvested, the drying process is carried out to further reduce the moisture content in the corn kernels. The corn kernels with low moisture content have a shorter drying time and a faster dehydration rate, which can greatly shorten the drying time. It can be seen from this that when the planting density is high, the water content in the corn kernels is less, and its quality is more in line with the demand. Reasonable planning should be made to make the water content in the corn more stable.
2. Effects on corn starch content
Corn contains a lot of starch, and corn starch is often used in the process of food deep processing, seasoning, and cooking. Therefore, the quality of corn is closely related to the starch content in corn kernels. The photosynthesis of maize plants plays a crucial role in the planting process of maize. Due to different planting densities, the photosynthesis efficiency of maize plants is also very different, which causes the growth cycle and speed of maize to be very different. When the planting density of corn is small, the plant can carry out sufficient photosynthesis, which can increase the starch content in the corn ear, make the corn ear plumper, and greatly improve the quality. It can be seen that when the corn planting density is low, the starch content in corn will increase, but the overall yield of corn will decrease; when the corn planting density is high, the starch content in the corn ear will be reduced to a certain extent, but the overall corn The yield can be guaranteed, and the relevant planters need to calculate the corn plant density, starch content and the overall yield of corn, and choose the optimal plan for planting to ensure the overall profit.
