Cultivation Technique of Loofah in Greenhouse
Loofah, also known as Tiansuogua, Tianluo, Quegua, Shuiguo, etc., originated in India and was introduced into China during the Tang Dynasty. Luffa feed on tender fruit, in which protein, calcium, phosphorus, iron and other minerals and carotene content are higher in melons. Loofah contains a variety of alkaloids, amino acids, saponins, loofah bitterness, citrulline, grenadine, etc., has a higher medicinal value. The technique of cultivation of loofah in the solar greenhouse is simple, and the operability is strong. It can realize a yield of 5,000 kilograms per mu, with an output value exceeding RMB 10,000. It is one of the relatively outstanding projects for farmers to get rid of poverty and lead a well-off society. Now we will introduce the cultivation techniques as follows: 1. Selecting the selected land: Choose loose soil and keep away from the “three wastes†pollution-free field for planting. Use early-maturing, high-yield, and disease-resistant varieties to reduce pesticide use. Huanghuai area generally use "Summer No.1", "Five-leaf sweet loofah", "early stick-shaped" loofah, "Yahua early good" gourd and other varieties. Second, nursery transplanting, scientific colonization. Lobster gourd is sown in mid-October in order to ensure that a large quantity of melon will be marketed before the Spring Festival. Seeding seeds for 2-3 days before sowing, hot 10-15 minutes in hot water at 55°C, then soaking for 6-10 hours, then germination under a condition of 30°C with a wet cloth, and sowing when 90% of seeds are exposed. Seedling soil treatment with disease-free soil nursery, the old seedbed to replace the new soil. The daytime temperature of the seedbed is controlled at 25-30°C, and is not lower than 15°C at night. When the first leaf of the loofah seedlings is unfolded, it is moved into a plastic nutrient bowl containing nutrient soil, which is conducive to the cultivation of strong seedlings. 40-45 days before colonization, the sunny morning was selected to be planted in a solar greenhouse. 20 days before planting, fertilize 3,000 kg of manure, 150 kg of cake fertilizer, 25 kg of superphosphate, 60 kg of compound fertilizer of nitrogen, phosphorus, and potassium, deepen 30 cm deep, and riddle by 90 cm line spacing. The upper ridge width is 40 cm and the height is 20 cm. Wide and narrow row planting, width 70 cm, narrow row 20 cm, plant spacing 35-40 cm. About 3700 plants per acre are planted. After planting, the film was covered, and the hole was broken to direct the seedlings out of the film. Third, Dingmiao management 1, temperature: less ventilation within 7 days after planting, in order to increase indoor temperature, promote early slow seedlings, slow greenhouse temperature control during the day in the 28-30 °C, above 30 °C put the wind, night temperature Keep at 14-16 °C. In case of cool weather, temporary warming measures should be adopted so that the night temperature is not lower than 8 °C. 2. Fertilizer: Organic fertilizer is mainly used, with little or no chemical fertilizer to reduce chemical fertilizer pollution. Before the combination of melon watering, topdressing Miaofei 1, can be applied to the manure excrement. After flowering and fruit setting, top dressing is applied once. Into the vigorous growth period, the demand for water and fertilizer increased significantly, generally every 15 days in conjunction with watering and irrigation once a fertilizer, each time acre can be applied to 20 kg of urea. Loofahs have a high demand for water and fertilizers, especially in the period of high levels of melons, where more fertilization and watering are needed. This is the key to ensure high yields. At the same time, on sunny mornings, carbon dioxide gas fertilizers may be added as appropriate. Pay attention to dampness after watering. 3, plant adjustments. When the loofah grows to more than five leaves, the vines begin to grow and should be tied in time. Usually, plastic vines are used to facilitate management and reduction. With the extension of the stems, the vines should be treated several times and the stems generally remain at a height of about 1.5 meters to prevent the top contact from being burned. In order to maintain the main vine's growth advantage, the first female flower was removed before all the side vines appeared, and after the emergence of side vine nectar, a leaf was preserved and the heart was picked up. 4, Paul Guava: loofah is a cross-pollination crops, under protected cultivation conditions, must be artificial pollination. The pollination time was artificially applied to flowers by 8 o'clock in the morning. Fourth, pest and disease control. Diseases of loofah include epidemic diseases, anthrax, downy mildew, and blight. For the disease at the beginning of the disease, it is sprayed with 75% chlorothalonil 800 times twice; anthrax is treated with 40% anthraquinone and 300 times for Fumei; and downy mildew is sprayed with 750 times potassium permanganate for 5-7 days. Spray 4 times. For the wilt disease, the diseased plants can be immediately disinfected with 20% lime water and then sprayed with 100-150 mg/kg of agricultural streptomycin 3 times. The main pests of loofah are maggots and whiteflies, and yellow traps are used to reduce the amount of pesticides and reduce pesticide residues. Fifth, timely harvest. Loofahs are mainly eaten with tender guarana, and the criteria for harvesting is that the fibers in the fruit are not hardened, the fruit-face hairs are reduced, and the peel is soft and harvested. The growth rate of the loofah in the greenhouse is extremely fast, generally it can be harvested within 10-12 days after pollination, and the harvesting should be carried out in the morning. The loofah has continuous and strong results, and it is harvested once every day in the fruit period.
