1. Temperature: sweet potatoes like a warm growing environment. The temperature must not be too low, so in general, they will choose a greenhouse when breeding in winter. The normal temperature shall be controlled between 22 ℃ and 25 ℃, and the temperature shall not be lower than 15 ℃. At the same time, if it is lower than 10 ℃, it will be frostbitten. The temperature in summer should not exceed 38 ℃.
2. Watering: it is necessary to provide sufficient water when seedlings are growing, so as to promote the growth speed of plants. At the same time, it is also necessary to maintain enough water during the growth period. However, in the rainy season, drainage should be done to avoid water accumulation and propagation of rotten roots, so as to greatly reduce the yield of stems.
3. Light: sweet potato is a light loving plant, which is most suitable for the full and warm sunshine. It can make the stem grow rapidly, and the sugar will be accumulated, which is more nutritious. The strong light in summer can also be well absorbed. If the light is not enough, the growth of the plant will be affected to some extent, the fruit will not be very strong, and the number of stems will be reduced.
4. Fertilization: the growth of sweet potato is inseparable from fertilization, and it needs to be applied irregularly, of which the main is nitrogen, phosphorus and potassium compound fertilizer, but it should be noted that sweet potato likes potassium most, so pay attention to the proportion when applying fertilizer, the proportion of potassium fertilizer should be the most
1. Propagation: seedling is the main way of sweet potato. When seedling is raised, you need to choose a good variety of sweet potato. Then the quality of each sweet potato is about 100g. The planting interval should not be too close, and it should not be buried too deep, otherwise it will affect its emergence. Then keep the environmental temperature between 25 ℃ and 30 ℃, and cut it when the seedlings grow six leaves. Come to plant
2. Pruning: there is no need to prune, because the last thing is to have its stem, which has no great effect on its branches and leaves, and has no ornamental value
1. Disease: black spot will appear, which will cause spots on the stems of plants, thus affecting normal sales and consumption. Carbendazim solution can be used to control and prevent
2. Insect damage: Spodoptera litura will appear, it will also affect the final fruit, you can spray trichlorfon solution control.
1. Toxicity: no poison, edible, safe breeding
2. Can you raise it at home? It's not suitable. It's a crop. Generally, it's most suitable to raise it in the countryside.
