Peanuts can be sown with shells, which has many advantages. Sowing with shell can reduce the cost of hulling; Peanut shell itself contains nitrogen, phosphorus, potassium and other elements, which can meet the needs of seedling growth without sowing and fertilization. The incidence rate is reduced by 20% ~ 30%, saving treatment investment; Sowing with shell can improve the disease resistance and epidemic resistance of peanut.

Peanut requires relatively high geological soil, so sandy loam land with relatively flat terrain and strong drainage ability should be chosen as the choice of peanut planting. Peanuts should not be planted any more. In the first year, the soil of peanut in China was not suitable for peanut continuous cropping. It is best to choose soil where peanuts have not been planted for several years.

Peanut is a relatively drought-tolerant plant, and generally does not need watering management in normal years. However, in case of extremely dry weather, especially in flowering period, it is necessary to irrigate peanuts scientifically and timely.

Extended data:

Ordinary peanut stems and branches are thick, angular and hollow. Anthocyanins in stems and branches are not obvious and are green. The main stem is completely nutritious and does not bloom, belonging to alternate flowering branching type. There are many lateral branches, often with multiple branches, and the total branch can be as many as 20 or more. Leaflets are obovate with green or dark green leaves.

The plant type of multi-grain peanut is erect and sparse. The stem is stout and tall, and there are 4-5 vegetative branches in the stem of the main stem, which grow upright in the early stage and tilt left and right in the later stage. All nodes can grow flowering branches, with few and long branches, few secondary branches, but no tertiary branches, and sparse long hairs on the stems and branches.
