Portulaca oleracea and gray vegetables are the most common grasses in the field. Many city people like to dig these two kinds of wild vegetables in the mountains and eat them at home. Of course, people here like to eat, but there are so many wild vegetables and weeds growing in the field that I'm afraid we can't eat them all by ourselves, so we can only get rid of them, otherwise it will affect the growth of corn. Portulaca oleracea and gray vegetables are especially fond of planting, but gray vegetables have a more pleasing feature, that is, they are easy to remove. Grey vegetables can be uprooted and piled up as long as they are pulled by hand.

But purslane can't. This thing is too tenacious. If purslane is not uprooted, it will grow again in a few days. Its nickname is "can't die". Unless the grass is uprooted, it will grow back in vain. When removing purslane, you can dig it out with your feet, then pick it up in piles and carry it out of the vegetable field, and it is best to remove purslane at noon. At this time, the sun is the most poisonous, and the picked purslane will wither a little in the sun, so it will die completely after being finally cleaned outside the vegetable field. If you just throw them into the ground, even after two or three days, they will wake up again as long as it rains a little. They are definitely cockroaches that can't be killed in the wild grass world.

In view of the above characteristics of purslane, once rural vegetable farmers find that purslane is flooding in vegetable fields, they generally adopt the following methods:

1. Pick game directly or make dried vegetables before flowering and seed setting, killing two birds with one stone.

Portulaca oleracea is a common ingredient of famous cold salad in northern rural areas in summer. It can be directly chilled after blanching, or it can be made into dried vegetables and soaked in winter. It has the functions of clearing away heat and promoting diuresis, detoxifying and relieving swelling, and stopping dysentery. The most amazing thing is that the omega-3 fatty acid content in Portulaca oleracea is extremely high, which can directly inhibit the absorption of cholesterol by human body and improve the elasticity of blood vessel wall. For cardiovascular patients, eating a little often is equivalent to diet therapy.

Treating weeds before sowing is also a valuable weeding experience summarized by farmers in practice. "You can weed and hoe the tender buds, but you can't weed and hoe the old autumn", which is the truth. If the grass seeds fall into the ground when they are ripe, it will be too late.

2. When planting vegetables, spread black plastic film directly to inhibit the germination of purslane.

In recent years, it has been widely used to lay black plastic film to inhibit the growth of grass in rural areas. In Axi's hometown, the technology of laying black plastic film in vegetable fields is very mature. Practice has once again proved that it can not only effectively inhibit the growth of grass, narrow the temperature difference between day and night, but also play a role in drought resistance and water conservation.

3. Spraying herbicides to remove purslane.

Anyway, no one sprayed any herbicides in the farmyard, but there were weeds such as purslane. Just pull it out by hand or hoe it a few times. Anything you want to eat in your mouth can be eaten without herbicides and pesticides.
