Why do you want to turn over the soil before planting vegetables?

The turned-out soil is soft and breathable, so rain can easily stay in the soil and air can also enter the soil. At the same time, when digging the soil, it can kill some insects hidden in the soil, so that the sown seeds can germinate and grow easily. Secondly, the way to change the loose soil compaction is to use soil ploughing to supplement the surplus.

Why dig the soil to dry before growing vegetables?

Turning over the soil is soft and breathable, so rain can easily stay in the soil and air can enter the soil.

At the same time, when digging the soil, it can also kill some insects hidden in the soil, so that the sown seeds can germinate and grow easily. Here are some specific values:

1, increasing soil permeability

The permeability of soil depends on the amount of particulate matter in the soil structure.

The more granular substances in the soil, the larger the gap in the soil, the looser the soil, the stronger the air permeability of the soil, and the better the ductility of the plant roots, which is beneficial to the absorption and utilization of nutrients by the plant roots.

2. Eliminate harmful components in the soil

Because vegetables have been planted in vegetable fields for a long time, a lot of chemical fertilizers and pesticides have been applied to the soil of vegetable fields, and the roots left by plants in the soil will rot and produce harmful gases under the action of microorganisms.

If these fertilizers, pesticides and harmful gases are not released and eliminated in time, it will do harm to the following crops. Therefore, the harmful substances stored in the soil will be eliminated with the help of intertillage.

3. It is beneficial to fertilization, burying impurities, intertillage and turning over soil.

You can also take the opportunity to bury soil surface residues and leaves, apply farm manure to the soil, effectively increase soil organic matter, reduce weeds and seeds in the soil surface, enhance soil fertility and improve soil circulation structure.

4. Eliminate pests and diseases in the soil

With the density utilization of vegetable garden, various soil-borne viruses and eggs also widely exist in the soil layer.

In order to reduce pests and diseases, intertillage can effectively reduce the occurrence of pests and diseases, especially in winter tillage, which can turn out pupae and eggs parasitic in the soil and freeze to death, thus reducing the occurrence of pests and diseases in spring.

5, change the soil moisture

Plants like to grow in a humid environment, but if the soil is too dry or too wet, it is not conducive to crop growth. Therefore, the way to change the loose soil compaction is to use soil ploughing to supplement the surplus.

Is it wet or dry to turn over the soil before planting vegetables?

There are no exact rules and statements about whether to water the vegetable fields first or turn over the land first, which can only be decided according to the field conditions at that time.

The temperature is too high in autumn, and the soil is seriously short of water. The direct-seeding vegetables should be watered first, and after three to five days, they can be ploughed intensively.

If it is to cultivate vegetable seedlings, it is necessary to intensively cultivate, adjust the drainage ditch to plant vegetable seedlings, and thoroughly water them.
