After the seeds of loofah in autumn were sown in mid-late July to mid-August, the growing season was experiencing high temperatures, a temporary shortage of rain and a season of autumn winds. It is very easy to cause the growth of seedlings and vines, with less results, more pests and diseases, and less profit. Therefore, we should pay attention to the cultivation and management:

First, nurture strong seedlings to protect the seedlings

(i) Selection. Choose early maturation, suitable for dense planting, disease resistance, high yield, anti-aging, good commercial quality, high yield in the early stage, long stick-shaped gourd varieties cultivation.

(b) Seed treatment. Soak the seed in warm water of 30°C for 3 hours, remove and then soak in 0.1% potassium permanganate solution for 30 minutes to sterilize, then rinse with clean water, put it under the ventilation condition to naturally germinate, and sow the seeds to whiten.

(3) Seeding and seedling management. For the nutrition cup nursery, mix the ripened soil with a small amount of high-quality chicken quail and put it in a well-packed glass. Leach the water, sow 1-2 seeds of germinated seeds for each cup, cover with a small amount of fine soil, and spray with a 1000-fold solution of Dixon. Then cover the seedbed with a cover to prevent sun exposure and heavy rain. During nursery, we must pay attention to keep the seedlings moist, but not too much water, so as not to cause leggy. 7 days before transplanting and planting, 2% potassium dihydrogen phosphate was sprayed 1-2 times to promote melon seedlings with dark green leaves, stout stems, and developed root system.

Second, colonization and field management

(a) Soil fertigation. 10 days before planting, combined with site preparation, per mu of perishable chicken, duck, pig manure 1500 kg, 100 kg of cake fertilizer, 50 kg of ternary compound fertilizer as base fertilizer.

(b) Colonization. Guamiao 4-4.5 leaves, seize the time to plant Daejeon. Close planting, 2 meters open, 2 rows per plant, plant spacing 25-30cm, planting 2200-2500 plants per acre.

(c) Pruning and pruning. Luffa is a climbing plant that must be placed in a flat shed before drawing vines, such as a bamboo pole, that is, each sloping pole and the opposite side of the squatter's squat group are built into an inclined rack about 2 meters high, on top of the roof. Longitudinal and horizontal, respectively, with bamboo or plastic webbing or wire pull knot into a net, loofah put vines in time after the introduction of vines, vines tied to the shelves, so that the vine leaves in the frame evenly distributed. The side vines that were not in front of the shelves should be completely removed. When the side vines on the shelves are to be seen, 2-3 guava buds should be picked in time; and the excessive male flowers are cut off. Then, two side vines are left on the main vine, and the remaining ones are removed. When these two vines grow to about 10 leaves, they also take care of emasculation, and pay attention to eradicate the old leaves of the lower part of the main vine, reduce nutrient consumption, and ensure that the fields are airy and transparent. In addition, we must also regularly cherish melons so that melons can be hung in sheds and plant adjustment work. It is advisable to carry out sunny afternoons to avoid damage to the leaves.

(D) fertilizer and water management. After the seedlings are leached, a thin excrement of water is added to promote the growth of new roots. When the first female flowers are pollinated and set fruit, holes are opened about 30 cm from both sides of the root, and 20 kg of urea per acre is applied to soak the cake fertilizer for more than 3 days. Kg, ternary compound fertilizer 25 kg for fruit fertilizer, promote fruit enlargement. The first batch of melon harvested 15 kg of urea per acre for the relay fertilizer. It can also spray potassium dihydrogen phosphate, foliar treasures and other nutrient solutions at the same time as spraying insect pests. Harvested fruit every harvest 1-2 times, about 7 days to catch a fecal water, human fecal urine water per 50 kg of manure water can add 100 grams of urea. If it is found that the deformed fruit should be watered in time to keep the soil moist, prevent the increase of malformed fruit caused by the rain after the drought and affect the product benefits.

Third, timely harvest in batches. The loofah was eaten with tender cucumbers, so the elasticity of the harvesting period was small. From the flowering to the commodity melons were generally cooked for 10 days. The fruit stems were smooth on the production, the fruits were slightly discolored, the hairs were reduced, and the peels touched with a soft touch. When it is shiny, it can be harvested. If it is not harvested in time, not only will the loofah fiber be aged, it will lose its food value, but it will also affect the fruit setting in the later period. When picking fruit, it is better to cut in the morning with a scissors handle.

Fourth, pest control. The main diseases of loofah include virus disease, downy mildew and powdery mildew, metalaxyl, triadimefon spray, and spraying every 7 days, even spraying 2-3 times. Insect pests are mainly locusts, melons, scorpions, and melons. The control can be used to dimethoate 800 times liquid, 5% stuck 1000 grams of liquid spray.
