Application of growth regulators to break the dormancy period of sweet potatoes and promote their growth
Gibberellic acid
Gibberellic acid has obvious germination effect. Low concentration and short-time treatment can increase the number of tubers sprouting, increase stems, and increase the dry matter rate, that is, increase the growth rate and enhance the growth potential of stems and leaves.In the early stage of germination, high-concentration or long-term gibberellic acid treatment significantly promoted the number of seedlings and the number of seedlings.Dip the potato pieces in 10-15 mg/L gibberellic acid solution for 10 minutes, or soak the seeds with 1 mg/L solution for 1 hour, remove them and dry them, and then raise seedlings in hotbeds, which can break the dormancy period and emerge early.
Naphthalene acetic acid
Bundle mustard and potato seedlings, soak the base with 10~20 mg/L liquid medicine to a depth of 1 inch (about 3.3 cm) at the base, and transplant the seedlings after 6 hours; or dip the seedlings with 80~100 mg/L liquid medicine for 3 seconds and plant them immediately, which can improve the survival rate , expand potato pieces, increase production.
Butyric hydrazide
The seedlings were soaked in 2500 mg/L liquid for 5~8 min before transplanting, which could promote rooting and improve the survival rate.
Choline chloride
When transplanting, soaking the incision in 20 mg/L choline chloride solution for 24 h can promote the growth of sweet potato hairy roots and early tuberous roots.
