2, according to the identification of female flower morphological features. The ovaries of female flowers of early-maturing watermelon varieties are generally round (some are also oblong), with less villus, thick and long stems, and large petals. Such female flowers are easy to sit on melons. Fruit-shaped elliptical watermelons (mostly late-maturing varieties) have long round ovary, many fluffs, thick and long fruit stalks, dense villi, large petals of female flowers are easy to sit on melons, and melons are large and of good quality; The handle is small and short, the ovary is smaller and round, and the villi are sparse. The female flowers with small petals are not easy to sit on melons. Even if they are sitting on melons, they are small, and the quality is poor and the yield is low.
3, according to the growth of plants, plants grow too busy or too weak, are not easy to sit melon. Overgrowth, the growth of vine leaves becomes a growth center, so that the nutrients are concentrated in the vegetative growth, seriously affecting the reproductive growth of watermelon, its performance is that the internodes become longer, the petioles are thin and long, the female flowers appear to be delayed, and it is not easy to sit melons. When the growth is too weak, the vine leaf is small, the petiole is thin and short, the leaf color is dark, the female flower appears prematurely, the ovary is small and round, and it is easy to shrink and metabolize the melon.
4, according to the ovary development speed. The ovary, which normally sits in melon, develops quickly after pollination and fertilization. After 2 to 3 days after pollination, the fruit stalk was elongated and curved, and the ovary was significantly enlarged. If the ovary develops slowly after flowering, the color is dull, and the melons with short stems are difficult to sit on, and the appropriate female flowers should be selected in time.
5. According to the availability of fertilizer and water, before and after the opening of the female flower, the fertilizer and water control is appropriate, and it is easy to sit on the melon. If the fertilizer water is too abundant or seriously insufficient, it can cause melon.
