Do summer and autumn vegetables still need to be covered with mulch?

Need. In the hot summer, covering the two-color film is more conducive to the growth of crops, because the two-color film has a reflective effect, the ground temperature is relatively low, and it is more balanced. In addition, for those areas where mountain vegetables are planted or there is no watering conditions, the two-color film is used to cover the ground, which can retain water, store water, and reduce the damage of weeds, which can be further applied in production.

In the hot summer and autumn, the temperature difference between day and night is large, mulching is more conducive to the growth of crops, because the mulch film has a reflective effect, the ground temperature is relatively low, and it is more balanced. In addition, for those areas where mountain vegetables are planted or there is no watering conditions, the two-color film is used to cover the ground, which can not only retain water, store water, but also reduce the harm of weeds, and can be further applied in production.

Mulch film can be covered in autumn, but in the autumn stubble vegetables have just been planted for a period of time, the main role that mulch can play in early autumn not only can not be played, and even the growth and development of vegetables is not good.

Depending on the temperature of the climate, it is generally only needed in late autumn or early spring in the north.

Because the mulch film is mainly to ensure the temperature, in addition to the benefits of maintaining the moisture of the soil and water. However, if the temperature is too high, the seedlings will be roasted, so the film will not be used in the weather with high temperatures.

In summer, when the weather is hot, mulching helps crops grow, because the two-color film has a reflective effect, making the ground temperature relatively balanced.

Problem analysis. First of all, if you plant cabbage in autumn, you must cover it with mulch in the northern region, because the temperature in the ninth lunar month in the northern region is already very low, and if it is in the south, you don't need to cover the mulch.

Q&A. The low temperature in the north needs to be covered with plastic film for insulation, and the high temperature in the south does not need to be covered with plastic film, and the main situation is flexibly handled according to the local temperature conditions.

Cabbage likes cool days, water and fertilizer are even, cabbage grows fast, and cabbage does not get sick, the advantage of cabbage without mulch film is that the cabbage absorbs fertilizer and water quickly, reducing the rate of cabbage disease.

If the cabbage is buckled with mulch, the cabbage will be hot under the roasting of the sun, and it is easy to get sick, especially the highest probability of macular disease, in addition to watering and fertilizing, the cabbage can not be absorbed, and the mulch film blocks the fertilizer and water, and the cabbage grows slowly.

Autumn cabbage is better to cover the mulch film or not to cover the autumn cabbage is generally planted in July and August Although it was the beginning of autumn at that time, but there was an autumn tiger, the temperature was very high, and the temperature inside the mulch film was even higher, so it was easy to kill the sprouts of cabbage seeds, so do not cover the mulch, which is conducive to the emergence rate.

Autumn cabbage, the cost of mulching will be higher, autumn cabbage, planted well, do not need mulch.

When planting autumn cabbage, it is necessary to cover the cabbage with film, and the benefits of helping to cover the cabbage are that it can increase the temperature of the land, promote the rapid growth of the cabbage, make the cabbage fruitful, improve the yield of the cabbage, and improve the benefits of the cabbage.

There is no need, Chinese cabbage seedlings need to be cultivated many times in order to achieve the purpose of rooting and strengthening seedlings. If the mulch film is covered, it will not be cultivated, but it will affect the early emergence of cabbage seedlings.

Autumn cabbage is good to cover with mulch, but the cost will be higher.

At this temperature, you definitely don't need to cover the film to grow vegetables. If the temperature is relatively low, it is necessary to cover the film, which can play a role in heat preservation and improve the germination rate of seeds.

This should not be necessary, because the temperature is relatively high in summer, and then there is no need to cover a film, otherwise his air will not circulate.

Spring planting vegetables need to cover the film, because the film can improve the temperature of the soil, maintain soil moisture, increase the role of fertilizer utilization, and the film can inhibit the growth of weeds, can reduce the breeding and reproduction of aphids, reduce the probability of vegetable infection, but after the emergence of vegetables, the film around the seedlings needs to be cut apart, so as not to grow poorly.

Planting vegetables in spring needs to be covered with film, because the film can increase the temperature of the soil, which is conducive to improving the germination rate of plants, and the moisture in the soil is mainly used in rainfall in addition to irrigation, and the water in the soil can be prevented from evaporating after covering the film, and when the rainfall is too large, the film can prevent too much rainwater from soaking into the soil.

The advantages of planting vegetable cover film in spring are to inhibit the growth of weeds, generally the amount of weeds in the soil covered with film is reduced by one-third compared with the amount of weeds in the soil without film, and the film has the advantage of reflectiveness, it can drive away aphids, inhibit the growth and reproduction of aphids, reduce the spread of diseases, and make vegetables grow healthily.

When planting vegetables in the spring, it is necessary to water them once after sowing to keep the soil moist, and then cover the soil with a layer of film, and the corners of the film should be compacted with soil so that it will not be blown away by the wind, and the film should be regularly checked for scratches by stones and other things.

After planting vegetables in the spring, it is necessary to cut the film around the seedlings after the seedlings emerge, so that the vegetables can receive fresh air, and let the vegetables receive all-weather natural light, so as to avoid poor plant growth, and compound fertilizer needs to be applied during the growth of vegetables to increase their yield.

<> spring planting can be according to the needs of vegetables to cover the film, covering the film can better improve the temperature of the soil, improve the germination rate of vegetables, after being covered by the film, the soil aeration is better, can accelerate the decomposition of organic matter, improve the fertility of fertilizer, accelerate the growth of vegetables. After the emergence of weeds in the soil, mulching film can well inhibit the growth of weeds. In the spring, you can grow vegetables such as eggplants, tomatoes, green peppers, etc.

1. Do you need to cover the film for planting vegetables in spring?

1. The ground temperature in spring is still relatively low, and covering the plastic film can increase the ground temperature by 2-4 degrees, which can promote the germination of vegetables and improve the germination rate.

2. The function of plastic film to increase the ground temperature is conducive to promoting the decomposition of organic matter, the soil is not easy to agglomerate, the aeration is good, and the soil fertility can be improved.

3. The aeration under the film is poor, and the temperature under the film is high, the weeds that emerge will die quickly, and the emergence of weeds can also be effectively inhibited.

4. Mulching needs to be determined according to the varieties of vegetables grown by yourself, spinach, coriander, garlic and other vegetables usually do not need to be covered with film.

2. What vegetables are suitable for planting in spring

1. Spring green onions: seedlings can be planted in mid to early March, and they need to be planted in a place with sufficient sunlight and close to a water source.

2. Eggplant: Eggplant likes temperature, generally planted in April warm spring, eggplant harvest period is shorter, the light requirements are higher, suitable for planting in the soil with sufficient light and strong fertility.

3. Tomatoes: Sowing can be carried out in late January or early February, tomatoes do not have strict requirements for soil, and need to be planted in relatively warm places.

4. Green pepper: Generally sowing in late April, like in moist soil, planting is generally about a week to emerge.

5. Rape: Rape has good cold resistance, can germinate at a low temperature of 4-6 degrees, and can be planted in mid-January.

3. How to cover the mulch

1. After sowing, the plastic film can be evenly covered on the ground, and the seeds can germinate as soon as possible after the ground temperature rises, and after germination, you can wait for the sprouts to directly open the plastic film or manually uncover the plastic film, so that the buds can grow out of the plastic film.

2. Do not cover the mulch film next to the plant, after the plant grows, you can expand the hole of the mulch film drilled out to increase aeration.

3. You can put some small brackets on the ground and then spread the mulch, do not let the mulch film stick directly on the ground, which will cause the water vapor in the film not to evaporate.

4. It is necessary to see when to cover the mulch film and uncover the mulch film according to the weather conditions, and the hot weather will cause the plants to die because the temperature is too high and the ground is too wet.
