Luffa is a plant of Luffa in Cucurbitaceae.

Annual climbing vines; Stems and branches rough, ribbed and puberulent. Tendrils slightly stout, pubescent, usually 2 to 4 forked. The petiole is rough, long 10 ~ 12 cm, with inconspicuous furrows and nearly hairless; The leaves are triangular or nearly round, with a length and width of about 10-20cm, usually palmately 5-7-lobed, with triangular lobes in the middle, long, 8- 12cm in length, sharp or tapering at the top, serrated at the edge, deep heart-shaped at the base, with a bending depth of 2-3cm, a width of 2-2.5cm, and a dark green at the top.

Monoecious. Male flowers: usually 15 to 20 flowers, born in the upper part of the raceme, the peduncle is slightly stout, and the length is 12 to 14 cm, which is pilose; Pedicel length 1-2cm, calyx tube bell-shaped, diameter 0.5-0.9cm, pubescent, lobes ovate-lanceolate or nearly triangular, upper end folded outward, length 0.8- 1.3cm, width 0.4-0.7cm, inside densely pubescent, with obvious edge and less outer indumentum. Corolla yellow, radial, 5-9 cm in diameter, lobes oblong, 2-4 cm long and 2-2.8 cm wide, with yellow-white villous base inside and 3-5 convex veins outside, densely pubescent on the veins, obtuse at the top and narrow at the base; Stamens are usually 5, sparse 3, filaments are 6 to 8 mm long, with white pubescence at the base, flowers are slightly closed at the initial stage of opening, and finally completely separated, and anthers are folded back and forth. Female flower: solitary, pedicel 2- 10 cm long; Ovary long cylindrical, pilose, stigma 3, swollen.

The fruit is cylindrical, straight or slightly curved, with a length of 15 to 30 cm and a diameter of 5 to 8 cm. The surface is smooth, usually with dark longitudinal stripes. It is fleshy when it is immature, dry when it is mature, with reticular fibers inside and cracking at the top. Seeds are numerous, black, oval, flat, smooth, with narrow wings. Flowering and fruiting period: summer and autumn.

growing environment

Illumination: Luffa is a short-day crop, which likes strong light and is resistant to weak light. Short sunshine and large temperature difference at seedling stage are beneficial to female flower bud differentiation, early fruiting and high yield. Short sunshine and high temperature in the whole growth period are beneficial to the growth and development of stems and leaves, maintaining healthy nutritional growth, and also beneficial to the development of flowering and fruit setting, young melons and the improvement of yield.

Temperature: Luffa is a thermophilic and heat-resistant crop. The suitable temperature for the growth and development of Luffa is 20-30℃, and the suitable temperature for the germination of Luffa seeds is 28-30℃, and it germinates rapidly at 30-35℃.

Moisture: Luffa likes moisture and is afraid of drought. Soil moisture is high. When the moisture content is above 70%, it grows slowly when it is below 50%, and the air humidity should not be lower than 60%. At 75% to 85%, the growth rate is fast and there are many melons. When the air humidity reaches saturation in a short time, it can still grow and develop normally.

Soil: Luffa is a vegetable crop, which has strong adaptability and is not strict with soil. It can be planted in all kinds of soil. However, in order to obtain high yield, loam and sandy loam with thick soil layer, high organic matter content, good air permeability and strong water and fertilizer conservation ability should be chosen as the best.
