1、 Variety selection

During cultivation, seeds should be selected according to the region. Different varieties have different dormancy habits. They should be selected according to the time of listing and the way of succession. Select some with good quality, strong disease resistance and high yield

2、 Sowing method

When sowing, the seeds must be spread evenly. After sowing, the seeds should be covered with soil, about one centimeter thick, and then compacted. Keep the seedlings moist before they are unearthed. Strengthen management and weed frequently during the seedling stage. When the seedlings grow to a height of 18 to 20 cm, they can be transplanted

3、 Land preparation and border cultivation

It is a perennial vegetable, which has not been cultivated for many years. Therefore, the land must be prepared before planting. We should first deeply plough the plot to ensure that the root system of seedlings can develop better. Fertilizer should also be applied. 5 tons of farm fertilizer, 40 kg of diammonium phosphate and 10 kg of potassium sulfate should be used per mu of land, and rotary tillage should be carried out twice to ensure better mixing of fertilizer and soil

4、 Colonization method

Planting should avoid the season of high temperature and high humidity. Those planted in spring should be planted after the summer solstice and those planted in autumn should be planted after the Qingming Festival. Ditch planting can be used. The row spacing shall be 30-35cm and the ditch shall be 10-15cm deep. After digging holes, plant 20-40 plants in each hole

5、 Strengthen management

Management must be done well after planting. In the later stage, we should frequently water and topdressing to ensure sufficient water and nutrients, so as to promote the better growth of seedlings. The seedlings should be watered every other week, especially before and after the start of autumn
