Luffa fruit is generally cylindrical or long-rod-shaped, nearly 20 ~ 100 cm, 3 ~ 10 cm thick, with no edges, unsmooth surface and many dark green longitudinal grooves. The fruit of luffa cornuta is rod-shaped, 25 ~ 60 cm long and 5 ~ 7 cm thick. The skin is green, wrinkled, with 7 edges, green or dark green. The seeds of Luffa are oval. Generally, the seed coat of Luffa is thin and smooth, with wings at the edge, which is black, white or gray. The seed coat of rib loofah is thick and wrinkled, and it is gray-black.
Luffa originated in Nanyang, bred in China in Ming Dynasty, and mainly produced in China, Guangdong, Guangxi and Hainan. Luffa has the greatest efficacy and function, and can be used as medicine all over the body. "Compendium of Materia Medica" records: "(Luffa) vegetables clear heat and benefit intestines". "Luchuan Materia Medica" also describes: "Luffa can quench thirst and relieve summer heat."
High-quality and high-yield seeds should be selected for planting loofah. Disinfect and soak before sowing, and then take it out with warm water. After picking the seeds, it is necessary to speed up the germination yield, pay attention to the nearby temperature, and keep them in an atmosphere of 25-30℃ for germination. Water the soil and sow it. Don't plant it too closely. After sowing, cover things to keep warm and moist. The key of loofah sowing is concentrated in two time ranges, one is February next year in 165438+ 10 and the other is June-September.
How to plant loofah and when to prepare seeds in advance.
Luffa can be planted according to the sowing method. Select high-quality and high-yield seeds. Seeds with yellow skin at maturity cannot be used for sowing, otherwise it will directly affect the emergence rate.
Disinfection soaking
Luffa can be disinfected with aqueous solution or soaked in hot and humid water. If you use the former method, you can prepare disinfectant, soak the seeds for a period of time, then take them out and rinse them with cold water. The second method is to prepare cold water at 55-60℃, put the seeds in it, then change it to warm water and soak it for several hours, which can also remove germs from the skin.
germination
After the seeds are soaked, they can be fished out. If you want to germinate quickly, you should pay attention to the temperature nearby and keep it warm in an atmosphere of 25-30℃ for germination.
Sow seeds
Water the soil and get it wet. After combing the soil, you can sow. If you must plant, you must pay attention to the planting density. You can plant two seeds in a small hole. Planting on the ground can cover wheat straw, and potted plants can cover fresh-keeping bags, all of which can play the role of heat preservation and moisture retention.
Sowing time
The sowing date of loofah is mainly concentrated in two time ranges, one is spring and summer165438+1October 65438+February, the other is autumn and winter from June to September.
