1, soaking seed germination, cultivation of strong seedlings snake melon seed coat thick and hard, must soak germination. The general sowing date is early February. Before sowing, the seeds were soaked in warm water for 15 minutes, then transferred into hot water of 50-60°C for 15 minutes, and continuously stirred. After being taken out, they were soaked in warm water for 4-8 hours. Then take out the seeds spread on the wet cloth and then covered with 2-3 layers of wet gauze, into the thermostat at 30-35 °C, germination, germination should pay attention to flip, and wash once a day, 2-3d seeds can be exposed white. Seeds can be sown when exposed. Use nursery nursery. Choose a sheltered area and arrange the nutrient solution on the seedbed. Mix the nutrient soil with 70% of the clean garden soil and 30% of the mature manure. Mix one seed each, cover the soil 1-1.5cm, and then cover the plastic film. Take a small arch and cover it with a plastic film. After the melon seedlings are unearthed, turn off the mulch. Seedling management to control the temperature and humidity and nutrients. The suitable temperature for the snake squash seedlings is 13-28°C, 23-28°C during the day and 13-18°C during the night. Increasing the temperature can shorten the seedling age. Growing at a suitable temperature during the day and appropriately lowering the night temperature is conducive to the accumulation of nutrients in the seedlings and promotes the formation of female flowers. 10 days before planting should be hardening seedlings. Master Shi Qin Qin Shi, generally 5-6d with the water to do some thin fertilizer, not too much so as to avoid leggy.
2, soil preparation, timely planting As the saying goes: melon planting buds, eggplant flowers. The melon seeds should be transplanted so that the roots are not damaged. When the seedlings grow to 2-3 true leaves, they can be planted. In the early spring, greenhouses can be cultivated in protected areas and the morning market can be mentioned. Combining ploughing and cropping, application of 45 tons of organic fertilizer and 900 kg of compound fertilizer per hm2 is carried out by means of application or application. Standard greenhouses generally do 3 畦, one 畦 one row, spacing 80-100cm. Covering with mulching film, digging the cruciform in the film according to the specifications, moving the seedlings into the hole, and then sealing the soil with the soil and pouring the water.
3. Scientific management timely harvest.
(1) Fertilizer and water management After planting and rejuvenation, urea 75kg/hm2 can be topdressed with water. The height of seedlings is about 30cm and then 120kg/hm2 of urea and 120kg/hm2 of compound fertilizer are traced back to the height of 100cm. In the result period, vegetative growth and reproductive growth are carried out at the same time. It requires fertilizer and water to increase. Therefore, timely irrigation is needed to keep the soil moist.
(2) scaffolding vines. Snake gourd grows vigorously, the melon shape is longer, generally take the horizontal scaffolding, height is about 2m, only leave the main vine before melon vine, remove all the lateral branches, wait for the upper shed and then let the lateral vine spread, and Lead vines to make them evenly distributed. After harvesting 1-2 times, no vines should be trimmed to avoid consumption of nutrients.
(3) timely harvest. From flowering to growing into melons, the growth time varies greatly with temperature. The temperature in the early spring is low, and the first batch of fruit must be harvested in 20-25 days. By June-July, the temperature will reach 30 °C or higher, and it can be harvested as long as 10-12 days. The early fruit grows up to 1m in length and the medium fruit grows to 1.5m in length. The yield is too low for the tender, and the commodity for the old is poor. Generally, the average weight is about 0.4-0.5kg.
(4) Pest control. Snake gourd has strong disease resistance, occasional viral diseases, anthrax and epidemics, but the incidence is lighter. Virus disease is found, it should be timely unplugged, and sprayed with virus A protection, while controlling aphids in order to avoid transmission. Snake gourd has a special smell and there are few insect pests. If pink butterfly and Spodoptera litura damage occur, Tianli and Tianba can be sprayed and killed in the young age.
