What are the key technical points for the cultivation and management of summer-sown peanuts?
How should summer-sown peanuts be managed? Please provide guidance. Summer-sown peanuts can be managed by referring to the following methods: 1. Check seedlings and reseed. After sowing, check the seedling emergence promptly. If gaps in the seedlings are found, promote germination and reseed in time. 2. Intertillage. During the seedling stage of peanuts, clearing the plants should be combined with intertillage. Generally, a small hoe can be used to dig away the soil around the base of the peanut seedlings to form a "small hollow", exposing the two cotyledons and the lateral buds in the leaf axils above the ground. At the same time, weeding can also be carried out in combination with intertillage.
