Snake-shaped loofah is an excellent variety developed from the Zhonghua system of local varieties in Yuhuatai District, Nanjing. This variety of melon strips is slender, thick meat, less fiber, heat-resistant, disease-resistant, high yield, high quality, is a rare "blocking fill-in" varieties.
I. Variety characteristics
The main vines are 7.38m long, 0.76cm thick, green, pentagonal, epidermal white bristles, branch number 8.8, branching node section 3. Dark green leaves, palmate pentagonal, with short, short bristles, leaf margin undulate. Petiole light green, round, with a ditch on the front. The flowers are yellow, the first male flower appears in Sections 3-5, and the first female flower appears in Sections 6-7. The fruit is green, slender and snake-like, with black ribs on the fruit surface and dense white hair. The flesh is light green, with a vertical diameter of 147.2 cm, a horizontal diameter of 6.5 cm, and a green handle with a single fruit weight of 109.6 g. The seeds are black and the number of grains is 110.3g. Early maturing, about 120 days after sowing. The result is strong, sometimes knotted melons. Strong heat resistance, can still grow normally under high temperature above 30°C.
Second, cultivation points
1, on the grab frame
Live or cotyledon transplanting, row spacing 4m (0.2-0.25) m, small shed plus mulching. When the seedling height is more than 50cm, the frame material is required to be 2.5m long. Every 4 to 5m standing 1 pile (9 head diameter at least 12cm) or cement column, according to the spacing above the size of bamboo or wire scaffolding, scaffolding about 2m high. Leave 2-3 vines per plant and spread them along bamboo or iron wire. The results initially in the distance 50cm away from the root of the ditch, the application of heavy fertilizer, fertilizer per 667m2 cooked 250-300kg cooked cake, plus 50-60kg three yuan compound fertilizer, the results of the period to ensure water supply. You can also keep a good melon road in advance, with the greenhouse precocious green leafy vegetables intercropping.
2, hi nest nest
(1) The sowing date for nursery in Nanjing is February 10-15. Seeds soaked with 0.1% potassium permanganate 10-20min or 55 °C warm water soaked to the natural temperature, set germination at 30 °C until the dew after sowing into a large-diameter nutrient bowl, electric heating line nursery. Greenhouses plus sheds covered with straw mulch. Seedling management must increase greenhouse temperature and reduce humidity, and prevent and treat diseases as soon as possible. 4 leaves 1 when colonized.
(2) Planting In late March to early April, rush to plant in fine weather. The cultivation method was adding greenhouses and sheds with plastic mulch, and the sheds were warmed for 1 week before planting, and evenly sprayed with Didiamine (100ml/667m2) liquid. The magpie nests were planted by size, with spacings of 40cm50cm and 667m2 of 2700 plants.
(3) After the management of live trees, 1 diluted manure water is sprayed, and 0.4%-0.5% potassium dihydrogen phosphate or other foliar fertilizers are sprayed on the leaves to keep the soil moist and promote seedling growth. Other management is the same as traditional cultivation methods.
(4) Insert the frame, tie the seedlings 30cm above the height of the insert frame, tie the vine. The Hi-Ling-style scaffolding is erected upright and then “S†shaped. Straw bales should be used for easy removal of vines in the future. The height of the shelves on both sides of the shed should be about 20cm away. When the vine grows beyond the top of the rack, it is plunged down to prevent the burn of the tip bud. In early May, the top film can be removed, and then a plastic rope, a film rope or iron wire is pulled in every 50 cm of the vertical shelf frame, and the roots are led to the scaffolds in the afternoon.
3, harvest loofah ovary lower position, when the corolla withered, melon surface ribs turn dark black when the harvest is appropriate. Generally, the output of the 667m2 can reach about 4000kg, while the early production of the hi-lack type scaffold is 4-6 times of the former, and the output value can reach 1 million yuan.
