Inhibit The Germination of Seed Potatoes
Application of regulators to inhibit potato seed sprouting
Chlorpropham
① Seed soaking treatment: select potato tubers with good appearance, no mechanical damage, and no disease. After placing them for 15 days, soak them in 1500mg/L chloraniline for 30 minutes, remove them from light, dry them, and store. It has a strong bud-inhibiting effect and can be effective. Inhibit the germination and growth of potato sprouts and reduce the consumption of nutrients.
②Fumigation treatment, 14 days after the potato is harvested, in order to inhibit potato germination during storage, 50% chloraniline hot spray 60-80g/L can be used to atomize the agent and use the aerosol circulation method to control airtight warehouses or cellars and other airtight conditions, fumigate potatoes. Keep the warehouse closed for more than 48h during the spraying period until the smoke completely descends. The safety interval of 50% chloraniline hot spray is 60d. ③For dusting, use 500-600g of 2.5% chloraniline powder per ton of potatoes (active ingredient 12.5-15g), and spread the agent layer by layer and evenly on the On the potatoes that are healthy and dry on the surface, use airtight materials such as plastic sheets to seal them as much as possible. After sealing and storing for 3-4 days, remove the covering materials such as plastic sheets and store them normally.
1-naphthaleneaceticacid methyl ester
Mixing methyl naphthalene acetate with attapulgite or other carriers to make powder, and spraying or spreading with 20-30g of 1-naphthaleneaceticacid methyl ester per ton of potatoes before storage can cause irreversible changes in the growth point of potato tubers, thereby prolonging the growth of potato tubers. Its storage period.
Abscisic acid (S-aba)
After selecting the potato tubers with good appearance, no mechanical damage and no disease, put them for 15 days, soak them in 4 mg/L abscisic acid for 30 minutes, take them out and dry them in the dark, and store them, which can prolong the dormancy of potatoes, the tubers germinate neatly, and consume more nutrients in the later stage.
