A cassava complex regulator for inhibiting branch and promoting tuberous root enlargement and a cultivation method
By combining auxin, cytokinin, gibberellin synthesis inhibitors and methyl jasmonate, along with brassinolide, phosphorus and potassium fertilizers and chelated trace elements, the problem of excessive branching in cassava has been solved, promoting tuber enlargement and starch accumulation, thereby improving cassava yield and quality. This method is suitable for large-scale cultivation in tropical and subtropical regions.

AI Technical Summary
Existing technologies for inhibiting cassava branching and promoting tuber enlargement suffer from low efficiency, unstable effects, and high costs. In particular, single plant growth regulators cannot simulate the synergistic effect of multiple hormones, leading to excessive cassava branching that affects yield and quality.
A combination of auxin, cytokinin, gibberellin synthesis inhibitor and methyl jasmonate, along with brassinolide, phosphorus and potassium fertilizer and chelated trace elements, was used to promote tuber enlargement and starch accumulation through two foliar sprayings and inter-row cultivation.
It effectively suppresses ineffective branching, increases tuber yield by 28-35%, and increases starch content by 3-4%. It eliminates the need for manual topping and pruning, making it suitable for large-scale, high-yield cassava cultivation in tropical and subtropical regions.
