The knotted melon, also known as the hairy melon, is a variant of the winter melon genus. The root system of zucchini is stronger, but weaker than that of winter melon. Stems are spreading, five-sided, with internodes 10-20 cm long, transverse diameter 6-8 mm, green, and hairy. The axillary buds of stem nodes are prone to side vines, so they have strong branching ability. When the vines begin to grow, each melon stem node still has tendrils, and the tendrils branch, and later there are flower buds, which differentiate into male or female flowers. The leaves of the zucchini are alternate, palmately 5-7-lobed, generally 18-20 cm long and 20-25 cm wide, with small notches on the leaf margins and a small serrated shape. The leaf surface is dark green, the back of the leaf is green, the petiole is round, and the length is 10- 15 cm, green, with hairs on the leaf surface, leaf back and petiole. The flowers of zucchini are unisexual and solitary. The calyx is green, the petals are yellow, each with 5 pieces; the male flower has 3 stamens, the petiole is 4-6 cm long, and the transverse diameter is 3-4 mm; the female flower has one pistil, the stigma is petal-shaped, three-lobed, the ovary is inferior, oval, long 3-3. 5 cm, transverse diameter 0. 8-1 cm, green, densely covered with hairs, stipe length 2. 5-3 cm, transverse diameter 4-5 mm pink. Plants generally develop male flowers first, then female flowers. After the first female flower appears, another female flower will develop every few nodes. In some varieties, female flowers may appear on two or more nodes in a row. The zucchini fruit is a gourd fruit. Both tender and mature fruits can be eaten, but it is generally better to harvest tender fruits for food. The young fruit is short or long elliptical tube-shaped, with several shallow longitudinal grooves or star-shaped green and white spots on the fruit surface, and is densely covered with hairs. The average fruit weight is 250-500 grams. Physiologically mature fruit, covered with white wax powder or not, generally weighs about 5 kilograms. The seeds of the zucchini are nearly oval, flat, slightly pointed at the seed hole end, light yellowish white, with raised ring patterns, similar to the pink-skinned winter melon seeds. ?

Huzi melon?: Pronounced hu zi gua

One of the common fruit trees, the plant, stem and leaves are very similar to gourds

The plant has soft vines, The leaves are green and heart-shaped, and sub-vines can appear on each node of the main vine. Female flowers appear on the first node of the sub-vine.

The melon is long and rod-shaped, with a length of about 70 cm and a transverse diameter of about 7 cm. The melon is green. White, a single melon weighs 0.5-1 kg. [
