Planting technique of Hedyotis diffusa

Planting Hedyotis diffusa should be planted in low-lying and sunny places, fertilizing the land and arranging sowing. The sowing time can be divided into spring sowing or autumn sowing, which is covered with fine soil after completion. After the true leaves grow out, it is necessary to carry out field management, mainly by watering and fertilization. Let the plant grow in a good environment, and finally arrange the harvest.

Planting technique of Hedyotis diffusa

1. Land selection and preparation

Hedyotis diffusa is suitable to be planted on low-lying, fertile and loose soil. After selecting the planting land, 4000-5000 kg of rotten farm manure and 50 kg of compound fertilizer are applied per mu as base fertilizer. Spread fertilizer evenly on the soil, rake fine and mix well, and then open a ditch to make a border, with a width of 1 meter and a depth of 25 centimeters.

2. Sowing seeds

The sowing time can be divided into spring sowing or autumn sowing, spring sowing is suitable for March-May, and autumn sowing is deformed in mid-late August. As the seeds of Hedyotis diffusa are small, in order to increase the germination rate, it is necessary to treat before sowing, remove the wax layer of the pericarp and seed shell, and then use the seeds to mix several times of fine soil before sowing.

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.

4. Pest control

Hedyotis diffusa has strong disease resistance, and few diseases occur in the whole growth period, which can be controlled by topdressing and weeding. The main pests are ground tiger and Spodoptera litura, in which Spodoptera litura can be trapped and killed by trapping lamp, while ground tiger can be sprayed with Regent.
