A method for determining the maturity of watermelon according to the days of female flowers

(agricultural Wealth net) the days from female flower blooming to fruit ripening of the same variety of watermelon are basically fixed under the same temperature. During flowering and fruit setting, different color marker sticks are inserted in the melon field every 3 days to mark the flowering date. Then calculate the development days of each batch of fruit (the same color marker stick), and then determine the harvest time. This is a more scientific and reliable method to determine maturity, and it is simple and easy to do. In general, it takes 28 to 30 days for female flowers to bloom to mature in precocious varieties, 31 to 35 days in mid-maturing varieties and more than 35 days in late-maturing varieties.
