In the planting technique of tribute vegetable, it is suitable to choose sandy soil with sufficient alkaline fertility.

The sandy soil with alkaline, sufficient fertility and strong ability of water and fertilizer conservation is the first choice for planting Gongcai. After the planting site is selected, combined with intertillage and fertilization to enhance permeability, the Beginning of Autumn can reasonably arrange density burrow sowing. It is necessary to accelerate germination before sowing, carry out low temperature treatment on the seeds, first soak them in cold water for a certain period of time, fish out and pour cold water and shade once a day, wait for them to germinate, pour enough water when planting, ensure that the soil is moist every day, and so on, ploughing and weeding regularly after emergence, and topdressing in time.

1. Land selection and preparation

The growth ability of Gongcai is strong, in order to improve its yield, it needs to be planted in suitable high-quality soil, which requires sandy soil with sufficient fertility, slightly alkaline, strong water and fertilizer conservation. After selecting the land, carry out soil preparation, check and deal with the residual herbicides and pesticides in time to prevent drug damage, combined with ploughing and fertilization, enhance permeability, disinfection and reduce the incidence of disease. After the Beginning of Autumn, the planting density should be arranged reasonably to dig holes and sow seeds.

2. Raising seedlings

Tribute vegetables are generally planted after Ching Ming Festival every year, and the best sowing time is about a week after autumn. Gongcai needs to soak seeds to promote germination before planting, and too high temperature will affect seed germination, so seeds need to be treated at low temperature before sowing. First of all, soak the seeds in cold water for about 3 hours. in order to ensure the appropriate temperature, the seeds need to be fished out and poured with cold water once a day. If the temperature is very high, the seeds will germinate in about 3 days.

3. Planting management

The seeds of Gongcai are small, the ability of top soil is poor, the temperature of sowing in autumn is relatively high, and the water loss is fast. It is necessary to pour enough water after planting, which is helpful to seed germination and emergence. Water properly twice a day after sowing to ensure that the soil is moist and covered with a layer of straw after watering to prevent water loss. In the later stage, in order to ensure the normal growth of seedlings, we need regular ploughing and weeding, preventing soil consolidation, fertilizing in time, replenishing the necessary nutrients and improving its yield and quality.

4. Rational harvesting

We should harvest tribute vegetables at the right time, otherwise it will affect its quality and output, neither too early nor too late. If the harvest is too early, the tribute vegetables are not mature, the yield is reduced, and the harvest is too late, the tribute vegetables are easy to be hollow and the nutritional value decreases, which is not conducive to storage. In general, the outer leaves and new leaves of Gongcai plant can be harvested evenly, and the harvest time can be determined according to different areas and plant growth conditions.
