I. What are the key points of organic vegetable cultivation techniques?

1. Choose suitable varieties

When cultivating organic vegetables, you must use organic vegetable seeds or seedlings, and choose vegetable varieties with strong disease resistance that suit the local geographical environment and climate type; do not use genetically modified or coated seeds.

2. Seed treatment

Before cultivating organic vegetables, seed treatment must be done well, using natural substances for disinfection, soaking in warm water, and so on.

3. Disinfection of soil and planting sheds

Before cultivating organic vegetables, the soil must be disinfected, using physical methods or natural substances, and no chemical agents. The seedbed should be disinfected three to five days before sowing; dilute wood vinegar and spray it on the seedbed, then cover it with prepared film or plastic mulch and seal it. You can also mix sulfur with the substrate and cover it with plastic film.

4. Fertilization

In the process of organic vegetable cultivation, organic fertilizers may be used; be sure to choose certified organic specialty fertilizers, and they can also be combined with some minerals. Fertilization is generally done as a base fertilizer, and if growth goes smoothly, no additional topdressing is needed.

5. Pest and disease control

Because no chemically synthesized pesticides may be used in the process of organic vegetable cultivation, the prevention of pests and diseases is mainly based on prevention, and can be done through agricultural control and physical control, such as in seed selection, high-temperature soil disinfection, crop rotation, diversified intercropping, and using natural enemies to deal with them.

II. How do you select and buy organic vegetables?

To choose truly organic vegetables on the market, consumers still need to pay special attention to the following points:

First, check whether there is a certification mark. This is the simplest way to distinguish them. Organic food in our country all undergoes on-site inspection and sample testing. Since July 2012, organic food has been traceable to its source code.

Second, look at the packaging. Mainly check whether the packaging bag of the organic vegetables is labeled with the producer, the certification body's phone number, name, address, etc.; these can also be looked up on the internet.

Third, look at the store. Organic vegetables bought from formal stores are generally more reliable than those from street vendors. You can go to a larger supermarket to make your selection, and when buying, first compare the above two points to see whether there is a certification mark and whether the packaging has the relevant information. In addition, the price of organic vegetables is a bit more expensive than that of ordinary vegetables.
