1. Sowing method.
The sowing method of peanuts is to sow in the field according to the cultivation method and cover it with plastic film. According to the operation mode, it can be divided into manual sowing and on-demand mechanical sowing.

2. Sowing density.
We should master the principle of reasonable close planting. The planting density of peanut is determined by plant height, fruiting range and leaf area. The suitable planting density of peanut depends on climate characteristics, soil fertility, variety selection and cultivation conditions. In general, plant spacing is 5 × 8 inches, and two seeds are sown. More than 23,000 basic seedlings were sown per mu, and about 20,000 seedlings were harvested. CDB uses a peanut-sized plow or peanut excavator as far as possible, with 6 rows in each row.
3. Sowing depth.
Generally, it is appropriate to sow peanuts about 5 cm. We should grasp the principle of "dry is not deep, wet is not shallow", the soil should be shallow, and the sand or sand should be deep.
The depth of open-air cultivation is not more than 7 cm and the shallowest is not less than 3 cm.
4. Post-sowing inhibition.
Postsowing inhibition is a successful experience to ensure drought-resistant sowing of peanut seedlings. After inhibition, it can not only reduce the evaporation of soil moisture, but also make the seeds closely contact with the soil, promote the rise of soil moisture, prevent the seeds from drying, and be beneficial to the germination and emergence of seeds.

First, the best planting time of peanuts:
Generally speaking, peanut is a thermophilic crop, so the temperature must be suitable, and the most suitable sowing stability is about 65438 02℃. At the same time, the suitable temperature for flowering is 23 ~ 28℃, and the lowest temperature is 19℃.
General peanut sowing date: when sowing peanuts, the ground temperature is 10 cm deep and stable above 15 degrees, which can be sown for 5 days. Remember, when the temperature is lower than 1 1 Celsius, do not sow to prevent seeds from rotting and seedlings from dying, that is, peanuts can be unearthed. Peanut seedlings are not strong enough, which affects the yield.
Generally speaking, the best sowing date of peanuts is from mid-late April to early May, that is, around Grain Rain. Plastic film mulching can be planted in advance until the middle and late March.
But different places have different climatic conditions, so when planting peanuts, we should decide according to the actual situation, but we must make sure not to sow when the temperature is too low!
Peanuts with shells should be aired for 2-3 days before sowing, peeled after airing, mixed with 50% imidacloprid suspension and gold suspension, and sown after airing.
Sow 2-3 seeds per hole, and the sowing depth is 1.5 inch. The soil with good clay and soil moisture can be shallow, and the soil with poor sand and soil moisture can be deep.
It is suggested to cover the peanut planting area with plastic film in spring and sow in advance to improve peanut yield.
In summer, peanut planting areas can choose interplanting and sowing in advance to increase yield.
Mastering the planting method and the best planting time of peanuts can not only prevent the problems caused by sowing, but also effectively improve the yield of peanuts.
