3. Field management

After the seedlings are unearthed, the seedlings should be combined with ploughing and weeding, and the weak seedlings should be removed between the seedlings, leaving strong seedlings with consistent growth. when the seedlings grow to 8-10 cm, the seedlings should be fixed according to the plant spacing of 10 cm. From sowing to seedling emergence, the soil should be kept moist and beneficial to seedling emergence, but stagnant water should be avoided, drainage should be done in time after rain, and water can be irrigated in the border ditch to cool down and prevent sunburn in the high temperature season. The growth period of Hedyotis diffusa is relatively short, and it needs to be fertilized in time to maintain nutrients. Generally, farm manure is the main fertilization, according to plant growth.
