Can overwintering tomato seedlings only be covered with mulch?

This can't work, only with plastic film will freeze to death, and it should be placed in a heating shed.

Look at you as a **, if you are in the south, you can do it, but if you are in the north, you will definitely not be able to do it.

It depends on which region you are, as long as you don't get frozen.

OK. First of all, we should pay attention to the impact of the weather, and try to choose sunny days for agricultural operations such as watering and fertilizing, spraying, pruning, etc., otherwise the humidity in the shed will be relatively large.

In winter, greenhouse vegetable planting should first consider reducing the humidity in the shed, and any field operation that will cause high humidity in the shed should be carried out on sunny days as much as possible. Otherwise, watering or spraying will cause the humidity in the shed to be particularly large, which will lead to poor plant growth, especially the aggravation of pests and diseases.

Tomato pruning should also be carried out on a sunny day. Tomato side branches grow vigorously, and in order to reduce the nutrient consumption of plants by these ineffective branches, tomato needs to be pruned almost every day during the peak growth period. The plant will inevitably produce wounds after shooting, and the wound healing will be slow on cloudy days, which will cause the infection of pathogens.

1. Tomato trees can spend the winter outdoors.

2. Generally, when wintering outdoors, it is necessary to spread several layers of straw and other warm items to the roots of the plant, and at the same time, during the maintenance, the family needs to properly destroy the reputation of the plant or reduce the water and nutrients, maintain the normal growth of the plant, and also need to prune the plant properly to help the plant save nutrients.

Tomatoes grown in northern winter and early spring need to be covered with mulch.

Summer and southern hunger recipes do not need to be mulched.

Tomato cultivation techniques.

Plot selection. You should choose deep soil, good drainage and irrigation, good ventilation and ventilation, and do not plant nightshade vegetables within 2 to 3 years, and do not choose areas without irrigation facilities for cultivation.

Breed selection. Choose varieties that are disease-resistant, high-quality, high-yield, resistant to storage and transportation, have good commerciality, and are suitable for market demand, such as Jintiewang.

Sowing seeds and raising seedlings. Sowing time in early March to early April is appropriate, according to the actual local situation reasonable arrangement of sowing time, the use of fertilizer ball way to carry out plastic film and small arch shed seedlings, and with the well-rotted farmhouse fertilizer mixed soil evenly pinched into a fertilizer ball of about 5 cm, and put a seed, evenly arranged with nutrient soil covering, at the same time apply a dilute water, covered with plastic film. Finally, it was covered with a small arch that was 8 meters wide and 8 meters long.

When there are 3** leaves growing, it is necessary to remove the film in time to ventilate and cool down, train the seedlings, and then plant them after a week.

Colonization management. Soil preparation and application of base fertilizer: 15 to 20 days before planting, apply 7 to 8 square meters of well-rotted high-quality circle fertilizer per mu, or 5 to 6 square meters of livestock and poultry will be stacked and fermented with the same amount of crop straw and then applied 100 to 150 kg of rotted cake fertilizer, using east-west high ridges.

If the greenhouse is cultivated 20 days before planting, the greenhouse is covered with film, and after the film is buckled, the bottom water is filled with ditching to irrigate the soil.

Planting method and density: plant spacing is kept at 50 to 60 cm, row spacing is kept at meters to meters, and 2000 tomato seedlings per mu are planted. At the same time, it is better to plant after 4 p.m. on a sunny day or on a cloudy day, and after planting, it is necessary to water the planting water thoroughly in time, and then water the seedlings once after 3 to 5 days.

Field management. Erection and pruning: when the tomato plant is about 30 cm high, it should be tied to the vine in time, and the frame is mostly used in the "human" herringbone bracket, after the bracket is laid, the tomato trunk is fixed on the bracket with a plastic rope in the shape of an inverted figure 8, and a single stalk is used to prune, each plant retains 5 to 6 spikes of flower spikes, and each spike retains 4 to 5 fruits.

In particular, it is necessary to remove the excess side branches in time and remove deformed fruits, diseased fruits, and excess fruits. In the later stage of growth, the lower old leaves and diseased leaves should be removed in time to reduce nutrient consumption and disease propagation, and enhance ventilation and light transmittance.

Cultivating weeding and cultivating soil: tomato seedlings can be cultivated and weeded after slowing seedlings, cultivating must be shallow and not hurt the roots, at the same time, remember that the tomato should be cultivated 2 to 3 times during the whole growth period.

Fertilizer and water management. Drip irrigation or dark irrigation should be used for watering, and the seedlings should be watered in time after planting, and the seedlings should be watered slowly after 3 to 5 days. The relative moisture of the soil is maintained at 60 to 70 percent in spring and 75 to 85 percent in summer and autumn.

According to the length of the growing season and the growth of the good return condition, top dressing in time. After deducting the basal fertilizer part, it is applied with water several times. It is worth noting that it is necessary to resolutely put an end to the use of organic fertilizers that have not been harmlessly treated, and it is advisable to use oil cakes and various biological fertilizers.

Do you need to mulch tomatoes for summer transplanting, black mulch or white mulch?

Personally, I recommend the black one. The ground temperature difference of black mulch film is small, the air permeability of black mulch film is better than that of white mulch, the plants of black mulch film are not easy to premature aging, and the ground temperature of black mulch film is high at night. Black mulch features:

The light transmittance of black mulch film is only 1% 3%, and the heat radiation is only 30% 40%. Because it is almost opaque, weeds can germinate and photosynthesize, so the weeding effect is remarkable. Under the sun, the black mulch film itself heats up quickly and has high humidity, but the heat transmitted to the soil is less, so the warming effect is not as good as the transparent film, and it also has a cooling effect during the day in summer.

When using, it is spread flat on the ground to expose the crop outside the film, or it can be tiled between the crop rows. Characteristics of white mulch: the thermal emissivity of white mulch film is 80% 90%, close to transparent mulch, and the light transmittance is only 40%, which has a certain inhibitory effect on weeds.

It is mainly used for tiling and mulching, which can better solve the problem of serious damage to the grass covered by transparent mulch.

Summary. Hello, I have helped you find the result: is the summer greenhouse tomato cultivation mulch film not exactly, because the tomatoes planted in the summer greenhouse may need to be cooled, and the mulch film will make its temperature rise, affecting plant growth and quality.

Although mulch can be used to grow tomatoes in summer greenhouses, it is more expensive, and it is necessary to check the condition of the mulch film frequently to ensure that the temperature is right, and you can also plant alder trees on the mulch to reduce the temperature. In addition, humidity control is also critical to ensure that the mulch film can effectively absorb and discharge surface water when it works. In addition, the use of mulch film also requires proper supplemental fertilizer to maintain the fitness of the plant.

Is black mulch okay.

Dear, yes, tomatoes grown in greenhouses can use black mulch. Because the black mulch film reflects sufficient solar energy back to the greenhouse, the temperature and humidity in the greenhouse can be kept at a suitable level, improving the cultivation environment, and can prevent the soil from absorbing solar energy, so that the soil temperature is lower, which is conducive to plant growth. In addition to this, the black mulch also helps to protect the plants from sudden heat attacks, can maintain the healthy growth of plants, and also prevents insect repellent pests and diseases, which is ideal for growing tomatoes in the summer.

Summary. Hello dear.

After the tomato plant reached a certain height, the effect of transparent mulch film and black mulch film was not much different, the black mulch film had a good weeding control effect, and the lower ground temperature was not greatly affected by sunlight. Transparent mulch film sunlight through the mulch film can be exposed to the soil, in the high temperature season soil temperature will be too high, is not good for slow seedlings, the surface of the black mulch film is very heat-absorbing, when the light is strong, the surface temperature of the film is high, and the seedlings will be scalded when they touch the black film. If the temperature is high when planting, whether it is black film, transparent film, after planting, it is necessary to seal the planting hole with soil in time, and the mound can be spread larger and thicker, which is beneficial to the seedlings.

It can also be planted for a period of time before mulching, which can reduce the evaporation of water from the ground, reduce the air humidity of the greenhouse, and save water.

May I ask the teacher, is it better to plant tomatoes with overwintering stubble, or is it better to spread white mulch, or black mulch?
