For areas where the gas festival has not arrived, although the recent temperature is very high, it is not recommended to plant. For example, the early-maturing peanuts in the Northeast are generally in the middle and early May. sowing.
2, 10-15 days after sowing temperature
The number of days of peanut emergence is closely related to the average temperature. It takes 20 days for 15 degrees after sowing and one week for 23 degrees. The temperature difference is about one degree, and the emergence time is wrong for one and a half days.
3, spring peanuts suitable for late broadcast
In the process of planting peanuts, the sowing date of peanuts during the sowing period is 25 days apart, which is matured mainly because of early sowing, low temperature, slow growth in all aspects, and high temperature and rapid growth during sowing, so the difference during maturity Not big.
Second, peanut cultivation methods
1, seeding method
Peanut sowing is divided into open field sowing and film covering sowing according to the cultivation method, and it is divided into manual on-demand and mechanical sowing according to the operation mode.
2, planting density
Planting density depends on local climatic characteristics, soil fertility, selection of varieties and cultivation conditions.
3, sowing depth
Generally, it is suitable for 5cm, and the deepest cultivation should not exceed 7cm, and the shallowest should not be shallower than 3cm.
4, after the suppression
Post-sowing repression can ensure the whole seedling, which can reduce the evaporation of soil moisture, and can make the seeds and the soil close contact, prevent the seeds from falling, and help the seed to sprout.
