What should be used to mark the fruit-setting day of watermelon?

Watermelon can be marked and recorded in batches with plastic ropes of different colors after flowering.

Marking method: it takes 30-35 days for early-maturing varieties to mature, and 35-40 days for mid-late-maturing varieties. After flowering, you can mark watermelons in batches with plastic ropes of different colors, calculate the growth days of watermelons, and pick them in time after maturity. If the weather is abnormal during the expansion of melons, samples of melons can be picked to detect their maturity, and then harvested in a large area.
