The latest course of field management techniques and methods of purslane

Purslane is an edible wild vegetable, which can also be used as medicine to treat some diseases. It is common to grow in rural fields or by the side of the road. Naturally fond of water, it must grow in a moist place, with strong adaptability and tenacious vitality. In recent years, there has also been a certain amount of artificial cultivation. In the process of cultivation, some field management is also needed in order to grow better.

First, water control

Portulaca oleracea needs a lot of water to grow. It likes a moist growth environment. Generally, the air and soil moisture should be maintained at about 80%. But at the same time, it is also very drought-tolerant and highly adaptable, so it can be watered again when fertilizing is particularly dry. In the prosperous period, you can water more in the right amount. But each watering should not be carried out when the weather changes suddenly and the temperature rises and falls.

II. Fertilization

The base fertilizer is applied before sowing, but there is no need to mix the seeds with chemicals, only herbicides that can kill other grass seeds but are harmless to purslane. To kill the weeds in the field. Then dig ditches and apply basic fertilizer in the ditch rows to cover the soil, and then ridge and plant on the ditch rows. Topdressing is generally carried out during the growth period, and a small amount of nitrogen fertilizer can be applied in the early stage to promote growth. In the prosperous period, I should top fertilize every other month, applying about 40 jin of my available nitrogen fertilizer per mu. After picking, it is necessary to strengthen the fertilizer and water to promote the production of new branches.

3. Control of tender leaves

The young leaves of Portulaca oleracea before flowering are the main edible part, and the stems and leaves will grow old if they bloom. So you must pick the heart and pinch off the top buds after each harvest. Promote it to continue to produce new branches, prevent its reproductive growth, let it continue to pull out new leaves for picking. Until the winter grows weak and withered.

Fourth, ploughing and weeding

After spraying pesticides before sowing, if other weeds grow in the later stage, they must be pulled out in time, and weeds compete for nutrients. After growing, they should be ploughed after heavy rain compacted the soil, ventilated and ventilated, so as to promote root growth and absorb nutrients.

When planting Portulaca oleracea, although it has strong adaptability and vitality. But artificial cultivation pursues benefits. Some specific field management measures are needed to limit the achievement of their own economic goals.
