The dwarfing and dense planting of loofahs can increase the early yield of loofah and increase the economic benefits. Loofah greenhouse is suitable for 6.530m, which is 10-20cm higher than ordinary vegetable greenhouses for easy operation and management. Variety selection of special greenhouse loofah species. 1 Seedlings 1.1 Prepare nutrients 钵 Use 钵 7-1 cm of nutrient 钵, 2600 pieces per 667m2 (2500 in actual planting). Prepare nutrients according to custom and mix carbendazim 3000:1. 1.2 sowing in early February, first soak the seeds with hot water, remove them and wrap them in a 30-50% environment with a damp cloth. The germinating soil was loaded into the nutrient bowl while germinating, and the soil was put into the mouth of the cornucopia at 1 cm and slightly pressurized. After the seeds have sprouted, they should be sown with 1 tablet per 2 grains, and then filled with nutrient soil. They should be discharged into a greenhouse in accordance with the specifications of a common seed bed and be irrigated with water. After laying a thin layer of film, they should take a small shed and close the insulation of the greenhouse. Generally about 15 days after the emergence of seedlings, Qi Miao, after removing the film and spray 1 thiophanate-methyl and trichlorfon pest control. When the temperature of the greenhouse is stable above 15°C, sprinkle the shed. 2 Transplanting 2.1 Fertilizer When the seedlings grow to 2 leaves, the greenhouse starts to prepare for soil preparation. After the ploughing (pre-irrigation), the middle 1.5m and 0.6m are built on the two sides, and the 667m2 high-quality farmyard fertilizer 2000-3000kg and compound fertilizer are applied. 30kg of urea and 10kg of urea were placed on the middle of the surface of the sampan. The sloping soil was covered with a small sorghum at the surface of the sampan. The width of the sorghum was 1m (edge ​​40cm) and the height was 15cm. Cover the film and close the shed. 2.2 When planting seedlings with 3 to 4 leaves, the seedlings can be planted. Before the planting, the seedling sheds should be uncovered and covered at early days for 3 days to strengthen the ventilation. On both sides of the width and width, the plants were planted at 35cm intervals, and the sides were planted with 70cm of dislocations on both sides. Water was poured to set the roots, and membranes were sealed. The insects were sprayed with insecticide, and then the sheds were closed. 3 Daejeon Management 3.1 Temperature and Humidity During the period of mild seedlings, greenhouse insulation should be promoted to promote seedling survival. Seedlings grow to 6-8 leaves, if female flowers are present, to ventilation, in order to facilitate the development of female flowers, the best 1-2 days ventilation 1 times. The temperature is lower than 10 °C without ventilation, sunny days should be enhanced ventilation, so that the greenhouse temperature does not exceed 25 °C. Until the temperature stabilizes above 18°C, the film can be removed. Luffa hi wet environment, not drought, water must be moisturized during drought. 3.2 After scaffolding seedlings survive, each nest is inserted with 1 bamboo pole, 1 pole and 2 rows with a human-backed frame, with 1 crossbeam running through, or 3 ropes tied into a tripod. Membrane 10cm, to prevent the wind through the shed film. 3.3 The main loofah on the whole loofah (side vines and tendrils must be cut off) has 2-3 strong female flowers after topping, so that the nutrients concentrate on the growth of the tender melons. After the first batch of melons grows to about 150g, leave 1 side vines for the second melon (pruning with the former), the second melon must be harvested before the first batch of melons. After 2-3 batches of melons, the vines have been placed on top of the shelves. At this time, all the old leaves in the middle and lower parts should be hit. From June to July, when the scaffolds are all covered, they can choose to keep l strong lateral branches in the lower part and cut the main vines for regeneration and cultivation. 3.4 Topdressing Luffa should not be fertilized in the early stage so as to avoid excessive growth of nutrients that affect the early fruiting. After each harvest of 2 batches of melon, 667m2 of compound fertilizer is applied to 20 kg of fertilizer once. If the growth potential is poor, it is necessary to add urea 5 to lokg. 3.5 The temperature of early artificial pollination is low, the ventilation conditions in the greenhouse are poor, and the insects are not easy to enter. Therefore, the pollination of loofah is poor, and it is best to add artificial pollination before uncovering the membrane in the greenhouse, especially the first batch of melons. Artificial pollination is carried out at 7-9am in the open morning of female flowers. Do not pollinate repeatedly to prevent the formation of cracks. After pollination, remove excess male flowers and buds. 3.6 Harvest According to the market conditions, loofah grow to about 300g can be harvested, early picking melon to promote early melon. Generally in mid- and late-April, it will be able to produce more than 3000kg per 667m2 in July and 4000-5000kg per 667m2 in Yanchi. 3.7 Pest control The main diseases are downy mildew and virus diseases. The pests include underground pests, yellow worms, and buds, which can be controlled with reference to conventional methods of cultivation.
