Sesame at home has grown to 4 to 6 leaves. Is this the best time to control prosperity?

Summer sowing should be before June 10 at the latest, with 400-500 grams per mu and about 0/0000 plants per mu. Ensure the formula of nitrogen, phosphorus and potassium and single application of chemical fertilizer, skillfully apply topdressing to seedlings at the early flowering stage and full flowering stage, and cooperate well with ridges, ditches and compartments to achieve drainage irrigation. Sesame is a warm crop. In order to sow sesame seeds evenly, the temperature in Grain Rain must be kept above 16 degrees after solar terms. If the temperature is too low, it will easily freeze to death and affect germination. Even after germination, sesame will rot when it meets cold roots in late spring. Hemp is a warm crop. In order to sow sesame seeds evenly, the temperature in Grain Rain must be kept above 16 degrees after solar terms. If the temperature is too low, it will easily freeze to death and affect germination. Even after germination, sesame will rot when it meets cold roots in late spring.

Spring sesame can be sown in late April to early May. Summer sesame producing areas are mainly in Henan, Hubei and Anhui provinces, and the cultivation system is mostly wheat-sesame, and rape, broad bean and pea-sesame are harvested twice a year. Sesame is a warm crop. In order to sow sesame seeds evenly, the temperature in Grain Rain must be kept above 16 degrees after solar terms. If the temperature is too low, it will easily freeze to death and affect germination. Even after germination, sesame will rot when it meets cold roots in late spring.

The standardized potato production system includes potato variety standardization, production environment standardization, seed potato breeding standardization, production management standardization and postharvest preservation, storage, transportation and processing standardization. Sesame is usually sown in the first half of May, and its germination and emergence need stable and suitable temperature. The minimum critical temperature for sesame germination and emergence is 15℃, and the optimum temperature is 18-24℃. Spring sesame is usually sown in the first half of May, and its germination and emergence need stable and suitable temperature. The minimum critical temperature for sesame germination and emergence is 15℃, and the optimum temperature is 18-24℃. Generally, in early May, this branch on our side is divided into effective branches and invalid branches. The more effective branches, the higher the yield. Branches at the base and top often become invalid branches, do not bear pods, only consume nutrients, and can be topped in time to reduce the invalid consumption of nutrients.
