Abstract

To mitigate the wastage of seed resources and reduce the usage of pesticides and fertilizers, seed coating agents have gained popularity. This study employs single-factor and multi-index orthogonal experimental design methods to investigate the seed coating formula and physical properties of Tartary buckwheat. The specific effects of each component on Tartary buckwheat seed germination are analyzed. The findings reveal that the seed coating agent formulated with 1.5% polyvinyl alcohol, 0.15% sodium alginate, 0.2% op-10, 0.1% polyacrylamide, 8% colorant, 3% ammonium sulfate, 1% potassium dihydrogen phosphate, and 0.15% carbendazim exhibits the most effective coating. It demonstrates optimal physical properties and promotes seed germination efficiently. The suspension rate of this seed coating agent reaches 91.12%, with a mere 2.13% coating shedding rate and 2.5% coating seed rot rate. Furthermore, it achieves a germination percentage of 99.17%, which is 20.84% higher than the lowest group. The germination potential and index are also significantly higher than the lowest group, with an increase of 20.84% and 26.56%, respectively. Additionally, the vitality index is 553.08, a 15.75% increase compared to the lowest group. The application of seed coating agents helps reduce seed resource loss, increase plant numbers, and ultimately enhance agricultural yields. This finding holds practical significance in agricultural production.
