Techniques of growing vegetables indoors

Now growing vegetables indoors is already a very common thing. Today, I will introduce the technology of growing vegetables indoors. If you master this small skill, you can also eat fresh vegetables at home.

How to grow vegetables indoors

1. Prepare the container

First of all, to prepare a container that can be planted, there is no extra flowerpot at home, you can use an empty oil barrel, punch holes in the oil barrel, usually just give enough water, you can grow quickly, and you can apply organic fertilizer properly.

two。 Planting method

Soak the seed for three hours, then put it in a refrigerator of about 4 degrees, refrigerate for about 20 hours, and then plant it in the soil.

3. Watering

When watering, the soil where the seeds are planted can be covered with a layer of hay. For about a week, small buds can be seen to grow. To keep the soil moist, as soon as the basin soil dries, water it immediately. When the leaves grow to about five, the vegetables are ripe and can be picked properly.

Second, how to choose and buy vegetables

1. Look at the color

In general, vegetables can be divided into two categories according to color: dark green leafy vegetables, such as spinach, amaranth, etc.; these vegetables are rich in carotene, vitamin C, vitamin B2 and a variety of minerals; light-colored vegetables, such as Chinese cabbage, lettuce, etc., some of these vegetables are rich in vitamin C, carotene and minerals. Some vegetables are abnormal in color, and attention should be paid, such as the leaves of vegetables lose their usual green and show dark green, and the green of edamame beans is abnormal. They may be sprayed or soaked in methamidophos pesticides before harvest, so they should not be purchased.

two。 Look at the shape.

Vegetables with normal shape are generally cultivated conventionally and have not been treated with chemicals such as hormones, so they can be eaten at ease. "abnormal" vegetables may have been treated with hormones, such as leek, which may have been used in cultivation when its leaves are particularly broad and thick, twice as wide as the average broad-leaf leek.

3. Look at the freshness

Excessive application of nitrogen fertilizer (such as urea, ammonium sulfate, etc.) will cause serious nitrate pollution in vegetables. Through the spot check of vegetables in the market, it was found that the order of nitrate content from strong to weak was as follows: root vegetables, potato, green leafy vegetables, cabbage, onions and garlic, beans, melons, eggplant fruits and edible fungi.

There are many kinds of vegetables and their nutrients are also different. eating more vegetables can supplement the energy needed by the human body and speed up metabolism.
