The latest common misunderstandings of vegetable plastic film mulching

There are many varieties of vegetables in our country, and no matter what vegetables are planted, mulching is very necessary. Mulching plastic film can effectively enhance the growth ability of vegetables, improve their yield and quality. However, many people have a lot of mistakes when covering plastic film. So what exactly are they? The following small series brings you common mistakes in vegetable film mulching. Let's have a look together!

1. The plastic film clings to the base of the stem

If the plastic film is not properly covered, it is easy to cause various diseases in vegetables. Many people will choose to stick the plastic film to the base of the vegetable stem when covering the plastic film. This is wrong and can easily lead to the death of the vegetable. When we open the mulch, it is best not to cut the mulch, but to open a larger opening by hand to avoid bridging, and to keep the diameter at about 6 cm. If the temperature is high, then roll up both sides of the mulch in time to avoid low temperature rise. Similarly, when the temperature drops, the mulch film should be spread out in time. Then clamp the adjacent parts of the mulch with clips to avoid the mulch touching the stems.

2, the whole shed is covered

Some vegetable farmers will directly cover the whole shed with plastic film when covering the plastic film. Then, during farming operations, the mulch is heavily trampled, causing it to stick tightly to the ground, thus reducing soil permeability. This hinders the respiration of vegetable roots, resulting in poor development of vegetable roots and decreased yield. When we cover the mulch, it is best to use steel wires and other substances to support the mulch, so that the mulch can be covered on the pole, and watering can be carried out under the film. In this way, it can not only improve the permeability of the soil, but also discharge moisture in time to avoid excessive humidity. If it is an operation line, it is best to cover crop straw, which is very beneficial to its growth.

3. Early coverage

The premature mulching time is also a misunderstanding that many people have. When we cover plastic film, we should adjust it reasonably according to weather changes and planting types. For example, after planting cucumbers in autumn and planting, if the surrounding environment is relatively high, then mulch. It will not only lead to too high temperature in the plastic film and stuffy seedlings, but also increase the humidity of the surface layer, which is very unfavorable to the root system of crops, thus affecting the squatting of crops. Therefore, we must pay attention to the weather conditions when covering the plastic film. Usually, we should cover it about half a month after planting to improve the rate of strong trees.

4, only in the operation line coating

Many people cover plastic film only on the operation line, but turn a blind eye to the planting line. And such a mulch, not only can not achieve the effect of film. On the contrary, it will lead to more obvious disadvantages and affect the growth of crops. Plastic film mulching is mainly to avoid high humidity in the shed, causing disease. And when we water, it is generally based on planting rows. If the planting rows are not covered, then they basically cannot reduce humidity, and the heat preservation is basically not available. And the soil permeability of the operation row will decrease sharply, seriously affecting the growth of crop roots.

The above is a simple introduction to the common mistakes of vegetable film mulching. Today's introduction is here, this article is for reference only, I hope to help everyone oh!
