Black-skin gourd is a late-maturing variety and management methods must be scientific. Agricultural resources network Xiaobian finishing skills for your reference.

1. Pest control

2. Use fine varieties. Such as "Giant No. 2" black melon melon (Guangdong Academy of Agricultural Sciences selected new varieties of vegetables). Its melon shape is long cylindrical, uniform, about 53 cm long, single melon weighing about 13 kilograms, excellent quality. The biggest feature of this variety is that when the melon reaches more than 3kg, the skin color has been converted from dark green to black and can be listed at any time according to the market price.

3. Suitable cultivation season. Spring sowing in Guangzhou is generally between January and February, and autumn is in mid-July. From early June to early July and winter in eastern Guangdong there is a certain risk.

4. Soil selection. Should choose sunny, well-drained, deep soil, organic-rich sandy soil planting, the direction of depression is appropriate to the north and south.

5. Colonization. Row spacing 1.5 meters, spring plants from 0.8 to 1 meters, autumn plants from 50 to 70 cm.

6. Fertilizer management. The principle of fertilization should be mastered, applied thinly, lightly weighted before and after, with a reasonable mix of nitrogen, phosphorus and potassium. Basal fertilizer is mainly farmyard manure, such as chicken cow dung, and phosphorus and potassium fertilizers are added in time after the flowers are given. After the fruit is served, sufficient water is supplied, and the water consumption is reduced 10 to 15 days before harvest to improve the storage and transportation performance of wax gourd.

7. Topping and snoring. Remove all side vines before fruit setting and leave 2 or 3 side vines after fruit set, allowing them to grow to 2 true leaves when they are topped, leaving the first and second female flowers to set aside in advance. If you want to stay on the market, you should choose to set up fruit in section 30. After the melons are seated, leave 15-20 pieces of healthy leaf topping.

8. Prevent falling flowers and falling fruit. Artificial pollination and growth hormone treatments can increase fruit setting rate. If the drop occurs due to low temperature, 2,4-D (15 to 20 μg) can be used for processing.

9. Harvest period. After 35 days of pollination, it can be listed, but it can also be marketed in combination with market conditions.
