Plant spacing and row spacing for corn planting vary depending on factors such as planting style, variety characteristics, soil fertility, and fertilization method. But in general, the line spacing is in50~60cm, plant spacing in24~30cmis a relatively common setting.
Specifically, the plant spacing of spring-sown corn is generally33~40cmwith line spacing50~60cm。Such a setting allows the density of spring-sown corn to reach per acre3300 4000 plants。The plant spacing of summer-sown corn is generally25~33cm, and the line spacing is the same50~60cm。Such a setting allows the density of summer-sown corn to reach per acre4000 4500 plants
In addition, there are also ways to plant in wide and narrow rows, that is, wide rows60~70cm, narrow rows40cm, plant spacing25~30cm。This planting method can improve the photosynthesis efficiency of maize, which is conducive to the growth and yield of maize.
Factors such as soil fertility, fertilization methods, growth periods, and variety characteristics should also be considered when determining plant spacing and row spacing. Generally speaking, plots with higher soil fertility and larger fertilizer application can appropriately increase the plant row spacing, and vice versa. For varieties with a long growth period and large plant size, the plant row spacing should also be appropriately increased to ensure the normal growth and development of maize.
In addition, planting density is also an important factor in determining the row spacing. Excessive planting density will cause maize plants to compete with each other for light and nutrients, affecting the normal growth and yield of maize. If the planting density is too small, it will lead to insufficient land utilization and waste of land resources. Therefore, when determining the row spacing of plants, comprehensive consideration should be made according to the actual situation to achieve the optimal planting effect.
In short, the plant spacing and row spacing of maize planting should be determined according to the actual situation to ensure the normal growth and development of maize and improve the yield and quality. At the same time, attention should also be paid to the influence of soil fertility, fertilization methods, growth period and variety characteristics on plant row spacing, so as to formulate a more scientific and reasonable planting plan.
