Black-skin melon is a mid-late maturity variety. After ripening, the epidermis is black, which is also known as black-skin melon. Yingde City, Guangdong Province is the main production area of ​​black-skinned melon. At present, the two-year planting efficiency is high. The two-year-old planting techniques of black-skin melon are now shared as follows.

First, choose the best sowing date

The first crop was planted in early and mid-March, and the film was covered with cold after the sowing; the second crop was planted from the end of July to the beginning of August.

Second, germination

The melon seeds must be buried in the wet sand before germination to promote the buds. The first melon should start germination 7 days before sowing, and the second melon should start germination 2 days before sowing.

Third, fine land preparation

Reasonable close planting: The melon land should be selected from the convenient and fertile sandy loam field. The ploughing and ploughing will smash the field and clean the debris, and then plant it in a single row. The specification is 1.5-2 meters wide. 70 cm, 650-700 plants per mu, 2 seeds of germinated seeds per hole.

Fourth, scientific fertilization

1. Apply enough base fertilizer: When the whole land is smashed, the farm will use 300-500 kg of manure or organic fertilizer, 50 kg of compound fertilizer, and the ditch strip will be planted after covering the thin soil.

2, skillful application of seedling fertilizer: when the melon seedling grows to 2-3 leaves, the use of urea or high-nitrogen fertilizer 15 kg plus compound fertilizer 15 kg with water to promote the melon seedlings.

3, heavy application of attacking vine attack melon fertilizer: when the melon seedling grows to 6-7 leaves should be re-applied to attack manure, 30-40 kg of compound fertilizer per mu, weak seed should be applied urea or high nitrogen fertilizer 5-10 kg . When the melon seedling grows out of the small melon, it should be applied repeatedly to attack the melon fertilizer, and apply 30 kg of compound fertilizer per mu. It should be applied with balanced and high-potassium products. When the weight of the melon is 7-8 kg, it is advisable to use high-potassium compound fertilizer and strong melon.

4, the top of the top dressing: after the flower buds open combined with the prevention and control of pests and diseases for root dressing, generally can be sprayed with potassium dihydrogen phosphate, high phosphorus and high potassium foliar fertilizer.

Five, take the vine, in addition to buds

Black-skinned winter melon melons are about 2.5-3 meters long. When the melons grow to about 1.5 meters, they should start to take the vines. Each plant uses 3 fences to form a tripod in the shape of "goods". In the middle of the tripod, a large fence is used to straddle the frame, so that the frame and the frame are connected together to grow and grow. . The melon is made up of the main vine, and the main vine has strong branching buds, so it is necessary to remove the side buds in time. The melon seedling grows when it grows to 18-20 leaves, and pollinates before 9:00 in the morning when it blooms. Generally, each main vine first leaves the first and second melons. When the melon grows to about 1 kg, the growth of the melon is then weakened and strong. Only one melon is left per plant, and the melon is fixed on the rack. After staying in the melon, the top vine is raised when 12-15 leaves are grown.

6. Prevention of pests and diseases

In the seedling stage, the melon seedlings are mainly affected by blight, blight, downy mildew, etc., and can be controlled by 克霜灵, ethylphosphonium aluminum manganese zinc, killable, mancozeb and so on. Insect pests include leaf miners, cabbage caterpillars, yellow squash, scorpion horses, etc., which can be sprayed with moths, farmland music, etc.

Seven, harvest

When the melon skin is turned into dark green and the melon leaves are yellow, it can be harvested. Generally, the first melon is harvested in mid-May and the second melon is matured at the end of November.

The above model and technology are used to grow black-skinned melon, and the yield per mu is 6000-9000 kg. When the market is good, the annual output value is more than 10,000 yuan. The black-skin melon has high planting efficiency and wide planting prospects.
