Prohexadione calcium is used during the sugarcane elongation stage, primarily by inhibiting excessive stem elongation, enhancing lodging resistance, and promoting nutrient translocation to the sugarcane stalks, thereby achieving the effect of height control and increased yield.
Hovedeffekter av Prohexadione kalsium:
1. Inhibits stem elongation and shortens internodes: Prohexadione calcium effectively interferes with gibberellin synthesis in sugarcane, inhibiting excessive elongation of internodes during the elongation stage, controlling plant height, making the stems thicker and stronger, and significantly reducing the risk of lodging.
2. Enhances lodging resistance: By shortening the length of basal internodes and increasing the thickness and bending resistance of the internode walls, Prohexadione calcium significantly improves the lodging resistance of sugarcane, especially in areas prone to strong winds and heavy rain or under high fertilizer and water conditions.
3. Promotes nutrient translocation to the sugarcane stalks and increases yield: While inhibiting vegetative growth, Prohexadione calcium promotes the accumulation of photosynthetic products in the sugarcane stalks, increasing sucrose content and dry matter accumulation, thereby improving yield and quality.
4. Forbedrer plantens fysiologiske status: Proheksadionkalsium kan øke klorofyllinnholdet i bladene og forbedre fotosynteseeffektiviteten; det fremmer også rotutvikling, forsinker aldring i de senere stadiene, og holder planten sunn.
Søknadsanbefalinger:
Application timing: It is recommended to apply foliar spray during the early stage of sugarcane elongation (5-10 days after the start of elongation). Dette er et kritisk vindu for å kontrollere overdreven vekst; påføring for sent vil redusere effekten.
Anbefalt dosering: Se bruksstandardene for avlinger som ris. Use 3-6 grams of active ingredient per 667 m² (approximately 1 mu) (the specific amount needs to be adjusted according to the product concentration and plant growth), diluted with water and sprayed evenly on the stems and leaves.
Precautions: Prohexadione calcium degrades quickly and has low residue, making it safe for subsequent crops, but it should be avoided to mix with strong acidic pesticides. Hvis det kommer kraftig regn etter påføring, kan det være nødvendig med ekstra sprøyting.
