Vegetable sweet potato leaf planting method

Vegetable sweet potato leaves can be planted on stents, appropriate amount of organic fertilizer should be applied during the growth period, watering every day in summer, and black shading net should be used to shade the sun, when the twigs grow to 5-6 leaves, they should be picked and eaten in time, and topdressing should be carried out after picking 2-3 times. if the plant shows premature senescence, the method of re-cutting and retraction should be adopted, and the soil should be ploughed and fertilized at the same time.

I. planting methods of vegetable sweet potato leaves

1. Plant adjustment

The main results are as follows: (1) the vines of sweet potatoes grow relatively fast, so they are prone to aging. When the twigs of sweet potatoes grow to 5-6 leaves, they can be picked and eaten in time, because the shoot picking can make the branches continue to branch and grow, generally far from the stem nodes of the ground. Its sprouting and growth ability will gradually weaken, so the branches on the main stem should not be too long or too much.

(2) the tender stems and leaves can be picked and eaten at regular intervals, and then 3-5 branches are retained on the main stem, each branch is 5 cm long, and all other parts are cut off. After waiting for 3-4 months, if the plant shows premature senility, it is necessary to take the method of re-cutting and retraction, at the same time ploughing the soil and fertilizing, the normal growth can be restored after about 15 days, and the scaffolds can be planted in flowerpots and then slightly tied.

2. Fertilization and disinfection

The main results are as follows: (1) generally, sweet potato leaves are not grown for potato production, but only for picking high-quality young shoots for consumption, so it is necessary to apply appropriate amount of organic fertilizer to supply the nutrition needed by the plant. After picking 2-3 times in a row, topdressing can be added properly. It can be irrigated or buried around the root system, waiting for about 7 days, and new twigs and leaves will grow.

(2) after planting sweet potato leaves for 3-4 months, it is necessary to replant, during which the soil will be ploughed, and then sufficient organic fertilizer will be applied, as long as the sun, water and fertilizer are sufficient, high quality sweet potato shoots and leaves can be produced continuously.

(3) in order to prevent soil diseases, when planting sweet potato leaves in the second year, it is necessary to change the soil, or you can choose to plant it alternately with other vegetables. When planting vegetables, all the prepared soil should be exposed and disinfected. During this period, no chemical agents can be applied.

3. Shading and watering in summer

Although sweet potato is a vegetable that likes the sun, the temperature of the balcony in summer is high and the light is strong, so it will lead to large water evaporation, which is not conducive to the robust growth of sweet potato leaves, and even will wither and die. During this period, black sunshade net can be used to shade the sun. At the same time, it needs to be watered frequently, and it can be watered every 1-2 days. Rain Water can be used in the rainy season to keep the soil moist, and artificial watering is only needed when the soil is too dry.

4. Weeding and loosening the soil

Planting in the soil with good fertilizer and water conditions is also conducive to the growth of weeds, so during the growth of sweet potatoes, weeds should be pulled out in time, so as to reduce the consumption of soil nutrients, and if soil consolidation is found during this period, tools such as a small hoe can be used to plough the soil properly to promote the growth of stems and leaves more exuberantly.

5. prevention and control of diseases and insect pests

Choose to plant sweet potato leaves on the balcony, as long as the method is proper, there are generally few diseases, but occasionally pests occur, mainly beetles, leaf rollers, ground tigers, sweet potato armyworm, Spodoptera litura and so on, during which manual capture can be carried out.
