Environmental requirements Luffa is a plant that likes temperature and is afraid of cold. The growth temperature range is 10~ 35, and the optimum growth temperature is 20~ 30. Can withstand at least 3 degrees and at most 45 degrees of light. If it is lower than 3 or higher than 45, the East China Sea and corruption may occur. Luffa has no requirement for soil quality. The land is high, the soil is moist, and it can be planted where there is no flooding, and the soil humidity is between 65% and 85%. When sowing loofah, it should be planted according to the local temperature, usually in the open field, mostly in spring and summer. It's warmer in the south, so you can sow in mid-February, and it's colder in the north, but you should sow before and after Qingming.

Sow saplings; Luffa can be broadcast live, planted and transplanted, or sold at a good price for early sowing. Choose a plot with no pests and high fertility, add a proper amount of mature farmyard manure, and evenly level the soil and fertilizer to make it a flat plot. (William Shakespeare Hamlet) There are many varieties of loofah. Choose the one that suits you, about 250 grams per mu. Before sowing, soak the seeds in warm water at 40 for about 5 hours, then soak the seeds in water, sprinkle the seeds on the ground, cover them with 3 cm of fine soil, sprinkle a layer of vegetation on them, sprinkle water on the head once, and gently pour in until the soil is wet. Then, bamboo is used as the arch frame and covered with film, but the seedling temperature is controlled between 20~ 25℃, and the seedlings emerge in a week or so, and the seeds are not fertilized. During this period, as long as the soil is wet, the towel gourd seedlings will grow to 10 cm, but they can be transplanted.

Land selection and land preparation; It is best to choose the highland with fertile soil, loose soil, good air permeability and convenient drainage in the loofah field. The best loam or loofah soil is beneficial to the growth of loofah root system and solves the contradiction of liking wet but not soaking. The pH value of soil acid is between 5.5 and 7. Turning over the field more than 25 cm in winter will reduce the soil quality in a winter, which will help to eliminate germs and pests, make the soil fertility and soil loose, and be beneficial to planting crops in the future, making the stems firm and increasing the yield.

One week before transplanting, put 1 ton of farmers' decomposed manure into 1 ton/mu, fully grind the decomposed manure and soil into manual or agricultural machinery and mix them evenly. (william shakespeare's Hamlet and Famous Farming Words) It is made of small ridges or ridges, and the convex shape can quickly drain water in rainy days. The standard width is 50 cm, and the pedestrian width and row spacing are1.2 m.

Planting and transplanting; In order to prevent weeds from growing much in the future, the topsoil herbicide can be sprayed once before dinner. When transplanting loofah, you must sow the root soil, treat the seedlings lightly and eat lightly. Generally, you should plant at a fixed point, with 2,500-3,000 Luffa seedlings per mu, blood depth 10cm, single-row planting, blood sugar 1-2 plants, Gru and Gru spacing of 30 cm, covering several centimeters of fine soil. After that, gently water the loofah temple. Technical management Luffa manual technical management is generally divided into: defense fee management, dried fruit film printing, and pest control. Water and fertilizer management: After the growth of towel gourd seedlings is stable, it needs to be watered in autumn to promote the growth of melon seedlings. Generally, urea is the main component, and appropriate amount of phosphate fertilizer and compound fertilizer can be added. Use urea 15 kg per mu, topdressing water, topdressing once every 10 day. Of course, animal manure can also be used, and fertilizer management can be appropriately increased in the later stage, and water can not be ignored. It's very dry and rainy, so it's best to water it every three to five days. If conditions permit, it is best to pour more animal manure to reduce costs and increase profits.

Construction film in-: If the towel gourd seedlings grow to 50 cm, you can build dome film, dome film, various construction methods, and make tripods or long plane frames. Loofah building membrane materials can be big bamboo and small bamboo, the height is about 2 meters, and dome membrane can be built to attract vines. When you tie vines, it is best to be at 5 pm.

Pest control: if the loofah is well managed in the growth process, there will be almost no pests and diseases. As long as there are powdery mildew, downy mildew, Fusarium wilt, angular leaf spot and so on. Pests include aphids, mites, leaf miners, etc. If pests and diseases are found, they should be prevented in time. The placement of pesticides is varied. Generally, chlorothalonil and carbendazim are sprayed for diseases. Pests can use dichlorvos and dichlorvos, and it is best to use pesticides according to the instructions before using them. You can spray it once a week, even once or twice.
