1, planting time of sweet potato leaves
Planting time: planting sweet potato leaves needs to choose the right time. Sweet potato grows vigorously in spring, so planting sweet potato leaves can be carried out in April-May in spring. It is necessary to observe the weather before planting. It is best to plant on or before rainy days, rather than in sunny or dry weather.
2. Planting method of sweet potato leaves
Planting soil: Planting sweet potato leaves requires selecting suitable soil. Sweet potato is suitable to grow in soil with rich trace elements and good drainage, so it is best to choose sandy loam or humus soil with rich nutrients and loose soil for planting sweet potato leaves, and the soil should be renovated before planting.
Sowing and leaf cutting: After the plot is treated, it can be directly sown and will soon emerge. When it grows to 5 inches, it is necessary to cut the leaves in time and cut them directly at the fork of the seedling.
Transplanting in time: If it is found that the planted sweet potato leaves germinate white roots, it can be transplanted. After transplanting, it needs enough sunshine and fertilizer to thrive.
Daily management of sweet potato
Temperature: Sweet potatoes like temperature, are afraid of cold and are not cold-resistant. The suitable growth temperature is 22-30℃, and the growth will stop when it is lower than 15℃. Different growth stages have different requirements on temperature, and the temperature in bud stage should be 18-22℃. Too high or too low temperature will affect the germination rate. The temperature of seedlings should be 22-25℃, the temperature of stems and leaves should be 22-30℃, and the temperature of stems and leaves should not be lower than 16℃, otherwise its growth will be hindered or even stopped.
Light: Sweet potato likes light and is a short-day crop. Plant growth needs high light energy, which is a crop that is not tolerant to shade. From the stem and leaf stage, the growth period of light energy is long and the photosynthetic efficiency is high. Otherwise, it will reduce photosynthetic efficiency and affect plant growth. The daily sunshine duration should be 8- 10 hour. Adequate sunshine can not only promote flowering and rooting, but also make more nutrients accumulate on the roots and promote the expansion of the roots.
