Abstract:

To clearly define the dosage and investigate the effect of seed dressing and spray with iron chlorin on the growth and yield of peanut, seed dressing with different concentrations of iron chlorin and spray treatment at different growth stages were used in this research. The results show that both seed dressing and spray of iron chlorin would promote peanut growth and branching, increase the number of corner fruit per plant and kernel weight, and increase peanut yields by 12.38%-14.29% with seed treatment method and 33.33%-55.87% with spray method. From the perspective of economy, the appropriate amount of seed treatment is 0.02% chlorin SP 0.20-1.00 g per kg peanut, and the appropriate concentration of spray is 0.02% chlorin SP 1000 to 5000 times.
