Temperature: The suitable temperature is 22℃~25℃, and the temperature cannot be too low. Watering: It is necessary to maintain sufficient water during the seedling and growth stages, and drainage should also be done during the rainy season. Light: Photophilic plants need sufficient light, and they need to receive at least 8 hours of light every day. Fertilization: It is necessary to apply sufficient base fertilizer, mainly potassium fertilizer. Fertile soil can make the stems fuller.

1. Maintenance methods

1. Temperature: Sweet potatoes like a warm growing environment, and the temperature must not be too low, so greenhouses are generally chosen for winter cultivation. The normal temperature is controlled at 22 to 25 degrees, and the temperature cannot be lower than 15 degrees. At the same time, if it is lower than 10 degrees, frostbite will occur. Summer temperatures also cannot exceed thirty-eight degrees.

2. Watering: sufficient watering is required when the seedlings are growing This can promote the growth rate of the plant, and at the same time, sufficient water must be maintained during the growth period. However, drainage must be done during the rainy season to avoid accumulation of water and the propagation of root rot, which will greatly reduce the yield of stems.

3. Light: Sweet potato is a light-loving plant that needs sufficient warmth. Sunlight is most suitable for it, allowing the stems to grow rapidly, accumulating sugars and making them more nutritious, and it can also absorb the strong light in summer well. If there is insufficient light, the growth of the plant will be affected to a certain extent, the fruit will not be very strong, and the number of stems will be reduced.

4. Fertilization: The growth of sweet potatoes is inseparable from fertilization. , and needs to be fertilized from time to time, mainly nitrogen, phosphorus and potassium compound fertilizers. However, it should be noted that sweet potatoes like potash fertilizer best, so when fertilizing, pay attention to the proportion. The proportion of potassium fertilizer should be the largest.

2. Breeding skills

1 . Propagation: Seedling raising is the main method of sweet potato. When raising seedlings, you need to choose a good variety of sweet potatoes, and the mass of each potato should be about 100 grams. The planting distance should not be too close, and the planting distance should not be too close, and it should not be buried too deep, otherwise It will affect its emergence. After that, keep the ambient temperature between 25 degrees and 30 degrees. When the seedlings grow about six leaves, they can be cut and planted.

2. Pruning: No need to prune, because it is necessary in the end. Its stems do not have much effect on its branches and leaves, and they have no ornamental value.

3. Problem diagnosis and treatment

1 . Disease: Black spot will appear. This disease will cause spots to appear on the stems of the plant, which will affect normal sales and consumption. Carbendazim solution can be used to control and prevent it.

2. Pests: Spodoptera litura will appear, and it will also It will affect the final fruit and can be controlled by spraying trichlorfon solution.

IV. Other issues

1 , Toxicity: Not toxic, edible, safe to breed.

2. Can it be grown at home: Not suitable, yes Crops are generally best grown in the countryside.
