How to determine the row spacing of peanuts

The row spacing of peanuts refers to the distance between rows and rows of peanut plants, ie, the distance between the plants when they are drilled; the plant spacing of peanuts refers to the distance between plants and plants of peanut plants, that is, the distance between plants. Reasonable plant spacing is an important part of rational and dense planting of peanuts. It is related to the competition among peanut plants for water, fertilizer, and sunlight, as well as to individual development. It is also related to the utilization of light energy and land use efficiency. When the plant spacing is too large, the single plant has large living space, sufficient sunlight, moisture, nutrients, and air, individual development is good, branches are early, branches are numerous, growth is robust, and the productivity of individual plants is high and neat and consistent, but due to the unit area If the number of plants is too small, ie, the population density is too small, the utilization rate of the collective light energy and the land use ratio are low, and it is difficult to achieve high yields. In turn, the plant spacing is too small. Because the plants are too densely distributed in the field, the competition between individuals, such as water, fertilizer, and sunlight, is too intense. The strong and weak seedlings are prone to occur, and the growth is irregular, and the branches are few, slow, and weak. Less, the group's output is not high. Therefore, a reasonable row spacing has an important influence on the individual growth and population yield of peanuts.

Row spacing is closely related to the sowing method, but planting methods with row spacing greater than plant spacing are generally used. For example, in the south, the double seeding spacing is 25-35 cm, the plant spacing is 15-30 cm, the single seeding spacing is the same as the double seeding, the spacing is 7.5-15 cm, and the single row spacing in the north is 35-45 cm, and the spacing is 13 -15 cm, double row ridges are 40-45 cm wide, 25-30 cm apart, 15-18 cm. The choice of planting methods must be determined according to the characteristics of the varieties, natural conditions, and the level of cultivation and management. According to another study, the reasonable row spacing should be equal to the row spacing equal to the length of one side branch in the first pair of side branches of the variety under cultivation conditions, and the spacing of the rows is slightly less than half the length of the side branch.
