Cultivation points of black-skinned wax gourd
1. Seeding and seedling raising: the seeds of black-skinned wax gourd are soaked and germinated, and then directly planted or transplanted. The temperature is low in early spring, so cold-proof measures such as small plastic film shed should be taken to raise seedlings.

3. Transplanting and planting: when the black-skinned wax gourd seedlings grow to 2-3 real leaves, they can be transplanted, and the planting specification is 0.7-0.9 meters, and they are planted in a single row.
4. Fertilizer and water management: Black-skinned wax gourd needs a large amount of fertilizer, so it should be fully applied with base fertilizer, with organic fertilizer per mu 1500-2000 kg, peanut bran 30 kg and calcium superphosphate 30 kg. After planting, apply nitrogen fertilizer once every 7-65 days and 438+00 days, and then apply topdressing again, with 40-50 kilograms of compound fertilizer and 60 kilograms of peanut bran per mu.
Wax gourd is thinly applied in Qin Ying, with light before and heavy after, and reasonable combination of nitrogen, phosphorus and potassium.

Before putting on the shelves, the main vines should be circled in the range of plant spacing, and pressed every 3-4 knots for 3-4 times, so as to promote the formation of adventitious roots and put on the shelves when it reaches about 16- 18 knots.
Scaffolding methods include scaffolding method and drum frame dragon root method. In Guangzhou, the drum frame dragon root method is often used. Three or four bamboo poles are used to build a drum frame, and a bamboo pole is horizontally placed on it as the dragon root.
When the wax gourd grows to 3-4 kg, wrap the melon handle with hemp rope and tie it to the dragon root of the drum frame.
After the result, about 15 knots were topped.
6. Keeping melons: Generally, it is in the 25th-32nd festival, and it is ideal to keep melons in the 3rd-4th female flower of the main vine.
When bad weather occurs during the fruit-setting period, artificial pollination should be carried out in the early morning to improve the fruit-setting rate, and the fruit-setting rate can also be improved by anti-falling agent treatment.
The selected young melons should be cylindrical, with the same size from top to bottom, wide and flat shoulders, pure round top and fluffy and shiny whole body.
After selecting the melons, the remaining young melons should be eliminated in time.

Control needs to spray Bataan 1000 times solution, Bisultap 400-800 times solution, Kangfuduo EC 6000- 10000 times solution, high-efficiency hero 2500-3000 times solution and pomfret 1 every 5-7 days.
8. Harvest: Generally, the black-skinned wax gourd can be harvested about 60 days after the fruit is set. At this time, the skin is shiny and dark green.
If the fruit is harvested too late, the nutritional components of the fruit will be transformed, which will affect the edible quality. Harvest in time.
The above is the introduction of planting techniques of black-skinned wax gourd. Friends who plant black-skinned wax gourd can refer to the above planting methods and plant them reasonably in combination with the actual planting situation.
