Cotton seed: never harvest prematurely opened bolls; pay attention when saving and selecting seed

From extensive surveys, the reasons for low cotton seed germination rates are: first, harvesting immature prematurely opened bolls; second, purchasing "favor bolls" with high moisture content; third, mixing in diseased seed from rotten cotton bolls; fourth, storing cotton seed in the warehouse before it is fully sun-dried; fifth, containing some cotton seed broken during processing; sixth, relatively high residual acid content in coated cotton seed; seventh, not strictly
