Field Management Technology of Portulaca oleracea

Portulaca oleracea is an edible wild vegetable and can also be used as medicine to treat some diseases. It usually grows in rural fields or on roadsides. Nature likes water, it grows in a humid place, it is adaptable, tenacious vitality. A certain number of artificial cultivation has also appeared in recent years. Cultivation process also needs to carry out a certain field management, in order to grow better.

I. Water control

Portulaca oleracea needs a lot of water to grow. It likes a humid growth environment. Generally, the humidity of air and soil should be maintained at about 80%. But at the same time, it is also very drought-tolerant and adaptable, so in the absence of conditions, it can be watered again under the condition of especially dry fertilization. In the long term, you can water more water. However, do not water each time the weather changes suddenly, the temperature fluctuates high and low.

II. Fertilization

Base fertilizer is applied before sowing, but seed dressing is not necessary, only herbicides that kill other grass seeds but are harmless to purslane need to be sprayed. to kill weeds in the field. Then dig ditches and apply base fertilizer in the covering soil layer in the ditch rows, and then ridge planting in the ditch rows. Topdressing is generally carried out during the growth period, and a small amount of nitrogen can be applied in the early stage to promote growth. In the prosperous long term, topdressing should be applied once every other month, and about 40 jin of quick-acting nitrogen fertilizer should be applied to one mu each time. After picking, it is necessary to strengthen the fertilizer water to promote the production of new branches.

III. Young leaf control

The young leaves of Portulaca oleracea before flowering are the main edible parts, and if flowering, the stems and leaves will become old. Therefore, it is necessary to pick the core after each harvest and pinch off the top bud. To encourage it to constantly produce new branches, prevent its reproductive growth, so that it constantly pumping new leaves for picking. Until winter, when it grows weak and withers.

IV. Intertillage and weeding

After spraying the pesticide before sowing, if other weeds grow in the later stage, they must be removed in time. Weeds compete for nutrients. After growing, heavy rain compacts the soil and tills it for a while to ventilate and promote the growth of roots and absorb nutrients.

When planting purslane, although its adaptability is strong, vitality is strong. But artificial cultivation pursues efficiency. Specific field management measures are needed to limit the achievement of one's economic goals.
