How many peanuts can be planted per mu in order to achieve high yield?

The reasonable close planting of peanut should be based on the sealing behavior of the plant in the fruiting period, and the general requirement of the appearance of peanut with reasonable close planting is that "the fertile land does not pour the seedlings, and the thin land can be sealed". Under general production conditions, under the conditions of long growth period, tall plants, strong branching, trailing varieties, as well as high temperature and rain, fertile soil and high level of management, sparse planting should be appropriate, and vice versa.

Peanut yield is determined by the number of holes per mu, the number of fruits per hole and the average fruit weight. The effective fruiting radius of peanut is about 15 cm for vine varieties and 10 cm for vertical varieties. Although there are many fruits per plant in sparse planting, the rate of blighted fruit is high and the yield is not high. Fuda peanut net-peanut high yield establishment center. If the density is too high, the number of fruits per hole decreases, the risk of over-ripe fruit proportion increases, and the yield and quality are not ideal.

Studies and experiments show that, affected by variety fruiting range, soil fertility and sowing date, the suitable density for spring sowing of common upright big fruit peanut in northern peanut area is 7000-9000 holes per mu (666.7 square meters), and common tufted and trailing varieties. 6000-7000 holes per mu Small and medium-sized pearl bean varieties, spring sowing dry thin land 10-12000 holes per mu, medium-fertile fields 7000 to 10, 000 holes per mu, Fuda peanut net-peanut high-yield establishment center. In the spring and summer peanut intercropping area in the Yangtze River basin, there are 9000 to 10, 000 holes per mu for common upright type, 6000-7000 holes per mu for common trailing and dragon type varieties, and 10, 000 to 12000 holes per mu for pearl bean varieties. In the spring and autumn double cropping area in the south, the pearl bean type peanut is sown in spring, 9000 to 11000 holes per mu, and direct seeding on dry sloping land, 10 to 12000 holes per mu.

The average row spacing of large peanuts is 40-50 cm, the hole spacing is 15-22 cm, and the row spacing of small peanuts is 33-39 cm and burrowing is 15-18 cm. Usually standing vine big peanut row spacing 42-46 cm, burrowing 15-18 cm, Fuda peanut net-peanut high-yield creation center. While the growth period of wheat interplanting or summer sowing peanut is short, and the plant is shorter, it is necessary to make full use of soil fertility and light energy, give full play to the population's potential to increase production, and appropriately increase density, and the general density is about 20% higher than that of spring sowing.
