1、 Curing method

1. Soil: the growing place of nettle is generally in the gully, river and other places where the soil is not very fertile. Therefore, when breeding, we should also choose the soil according to its growth habits. The first condition to be met is drainage, because if the drainage is not good, the roots of the plant are easy to be flooded, so we must choose the drainage soil. The growth of plants requires certain nutrients, so the fertility of the soil should also be taken into account. To sum up, the soil suitable for the growth of nettles should have drainage and fertile soil

2. Watering: before watering it every time, you need to observe the state of the soil. You can only water it when the soil is completely dry. According to common sense, when the plant seedlings grow to about 30cm, they need to be watered once, and before closing the ridge, they need to be watered once. In case of dry weather, manual watering is required, and the watering frequency is once a week

3. Fertilization: when sufficient base fertilizer is applied, top dressing is also required according to the growth state of nettle. Especially in the growth period, nitrogen fertilizer is needed to meet its growth needs. If the plant is growing in a healthy state, it is OK to apply fertilizer once a month

4. Light: if the light is insufficient, the plant will grow poorly. Therefore, in the process of growth, it should meet its light needs at least five hours a day

2、 Breeding skills

1. Breeding: it can use ramet breeding, and the breeding time is in the first ten days of April every year. Firstly, the seed roots should be collected, and then customized. According to the line spacing of 70 cm, the plant spacing is 20 cm, the hole depth is 30 cm, and finally covered with soil of 5 cm, watered with enough water, the seedlings can emerge in about 10 days

2. Weeding: weeding is carried out for the first time after the seedlings are out, and there is no need to weeding after Ridge closure

3、 Problem diagnosis

1. Insect pests: aphids and leaf miner flies are easily infected during the growth period. They will eat the tender leaves of the plant and affect the growth. If found, Omethoate can be sprayed for treatment

2. Disease: it is easy to induce powdery mildew when hungry in high temperature season. You can use doctor Bai to spray it once a week and eradicate it about three times

4、 Other issues

1. Edible: it is edible

2. Whether it is suitable for family breeding: there are small thorns on the edge of nettles, which are easy to sting, so it is not suitable for family breeding
