How to plant peanuts

Seed germination needs higher temperature, and the suitable temperature for pearl bean type is 12- 15℃, and for common type is 18℃. Some varieties have strong dormancy and are difficult to germinate at low temperature. After the seeds absorb water, the contents are converted into sugar, which is easy to attract underground pests such as ants to bite.

Therefore, mastering timely sowing is the key to the whole seedling. Don't cover the soil too thick, and 5-7 cm is appropriate when the soil moisture is good. When the thickness of covering soil exceeds the normal extension length of hypocotyl, it should be removed.

"Clearing trees and squatting seedlings" is a measure to dig the soil surface with a hoe after emergence, so that cotyledon nodes are exposed from the soil surface, which is beneficial to the growth of the first pair of lateral branches and more flowers and fruits. In principle, the planting density should not only keep the field ventilated and transparent, but also cover the ground in the late growth period to prevent soil moisture evaporation and inhibit weed growth.

Extended data:

The maturity time of pods is very inconsistent. The pods can be peeled off, and when the color of the inner wall or endocarp of most pods changes from brown to black, the harvest can begin.

Varieties with late harvest and weak dormancy are easy to germinate in the field; Some varieties are easy to break fruit stalks and it is difficult to harvest them cleanly. In mass production, the harvester is used to dig over the sun, and then the fruit is picked, cleaned and dried by the fruit picker.

The water content of safely stored pods is 10%. It is very important to dry in time, otherwise it will be hot and moldy.
