It is difficult to manage vegetables in winter greenhouses, what should I do?

In order to keep the vegetables in the winter greenhouse good and robust growth, and have a higher yield and quality in the later stage of vegetables, our vegetable farmers must do their best to do a good job in temperature regulation, heat preservation and heating management, create a suitable temperature environment for the normal growth and development of vegetables and flowering and fruiting, and at the same time prevent vegetables from freezing at low temperatures under the influence of cold waves and cold air.

At this time, some professionals should be asked to make some relevant suggestions.

Regional planting, reasonable planning of vegetables in the greenhouse, can be effective management and fertilization, but also to provide good convenience to people.

In fact, whether it is planting vegetables or farming, we all know that from the process of assisting in breeding, to rapid growth and ready to go on the market, the feed, temperature, environment, etc. are different; So it's the same as growing vegetables as we do.

<> there are problems from the beginning of seedlings, to the rapid growth period, and finally to the market, one is the temperature. the second is to maintain the freshness of vegetables; The third is to take into account the time of market transportation, neither too early nor too late, to ensure that the vegetables in the hands of customers fresh, healthy, not damaged, not damaged. First of all, we all know that for greenhouse vegetables, doing a good job of temperature management is a very important link, which directly affects the harvest of farmers.

The greenhouse is selected in the sunny place, which is conducive to the increase of the temperature in the greenhouse on the one hand, and can also promote the effective growth of vegetables on the other hand. For the winter greenhouse, it is necessary to use a thick soil wall on one side and two doors with thermal insulation cotton pads at the entrance. If it is a continuous cloudy day, you can cover the shed with a straw curtain in advance, which can also play a role in heat preservation.

Whenever a cold wave hits, it is often accompanied by strong winds to cool down, so it is necessary to strengthen the greenhouse to prevent it from being blown away by the wind.

Plant antifreeze can also be sprayed. In short, there are many ways to use, learn from experience, welcome ** intelligent greenhouse planting system can help shed friends avoid this problem. Kaiyi intelligent greenhouse planting system can monitor the temperature and humidity, soil moisture, illumination, photosynthetic efficiency, carbon dioxide, illuminance and other data in the greenhouse, and transmit it to the cloud platform for processing through wireless technology, and display it in real time on mobile phones, computers and tablets.

Users can also control the wet curtain fan, sprinkler irrigation and drip irrigation, internal and external shading, top window and side windows, heating and supplemental lighting and other equipment in the greenhouse through the software platform. In order to realize the intelligent management of greenhouse planting, reduce the workload of users, and save the labor cost and management cost of users.

The management of greenhouse vegetables in winter is very important. It is necessary to carry out regular ventilation and drying, and pay attention to temperature control, otherwise severe frostbite will occur.

One is the temperature, the second is to maintain the freshness of the vegetables, and the third is to take into account the time of market transportation, neither too early nor too late, to ensure that the freshness of the vegetables in the hands of customers is not damaged or damaged.

Winter management of greenhouse vegetables is very important. Regularly ventilate and dry, pay attention to temperature control, otherwise it will cause severe frostbite.

Thicken the insulation layer, control the indoor relative humidity, increase the heat capacity of the soil, apply organic fertilizer, and pay attention to light.

The following points need to be considered in the management of greenhouse vegetables after planting:

1. After the vegetables are planted, the temperature is controlled by closed greenhouse mulch. Generally, the daytime temperature is controlled at 25 32 and at night at 20 25. When the sunlight is strong and the temperature in the shed exceeds 30, a shade net can be used to cool down and promote the slow seedling.

After the seedlings are slowed down, they should be cooled properly. Generally, the temperature is controlled at 20 25 during the day and 15 20 at night. The suitable temperature for the growth of melon and eggplant vegetables is 20 30.

If the temperature exceeds 35, growth and development will be stunted. Therefore, when the temperature of eggplant, fruits and vegetables is greater than 30, and the temperature of melons and vegetables is greater than 32, ventilation should be carried out from small to large. When the temperature stabilizes at 17 at night, the skirt film can be removed and the top film can be retained in case of rain.

Temperature and humidity can be controlled by the size of the ventilation and the morning and evening of the film covering. In cloudy and rainy weather, the inner membrane of the greenhouse should also be removed to allow the vegetables to see the scattered light to prevent the weakening of plant photosynthesis and malnutrition.

2. When the vine vegetable plant height is about 30cm, the vine should be led to the shelf in time to hang; For eggplant and pepper, remove the side branches below the eggplant (piperine); Tomato pruning varies according to the planting density. Dense planting is generally pruned with single stem, and thinning is generally pruned with double stems; Cucumbers and pumpkins are mostly single-vine pruning. Remove the old leaves, diseased leaves, diseased branches and diseased fruits of vegetables in a timely manner, and carry out centralized external treatment.

3. The application of hormones in eggplant and fruits and vegetables can easily cause flower and fruit drop when the temperature is too high or too low. Plant hormones can be used to protect flowers and fruits. Eggplants and tomatoes can be soaked or garnished with tomato wine, or garnished or dipped with anti-fall elements; Pumpkins, zucchini, and cucumbers can be soaked with a strong fruit-setting spirit and can be artificially pollinated when pollen is present.

The above hormones should be labeled with pigments to avoid repeated use leading to abnormal fruits. The concentration of the hormone should be adjusted according to the change in temperature. The concentration is higher when the temperature is low and lower when the temperature is high.

4. Fertilizer and water management is mainly the result of early control of melons, fruits and vegetables, eggplants and melons and fruits. After the results are out, top dressing is carried out according to the growth of the plant. Top dressing is generally carried out 2 to 3 times.

Top dressing can be cavitous, furrow or foliar spray. Fertilizers can be compound fertilizers, well-decomposed human and animal manure, potassium dihydrogen phosphate, and nutrients. In the early stage of fruiting, apply 45 60kg per mu, strips or holes, with a depth of about 5cm, and maintain a certain humidity.

Watering should be carried out according to the temperature and the dryness of the soil in combination with top dressing. When the temperature is high and the soil is dry, it should be watered or run water in time.

The above is the management method after greenhouse vegetable planting, I hope it will help you.

After the greenhouse vegetable planting needs to be managed by scientific methods, we must pay attention to cleaning up the dust stains on the greenhouse when managing the greenhouse, ensure sufficient sunlight, water on time, loosen the soil, clean up the surrounding weeds and dead leaves, prevent pests and diseases, spray the nutrient solution on time, so that the vegetables can grow better, the color is bright, and the color is beautiful.

If you want to manage it after planting, you need to control the temperature of the vegetable greenhouse, and then try to let these plants get light and ventilation properly. In addition, it is also necessary to water and fertilize in time, so that the vegetables can grow better and better.

It must be ventilated frequently, it should also be watered and fertilized in time, to ensure the fertility of the soil, it is necessary to do a good job of loosening the soil, it is necessary to water and fertilize in time, and it is also necessary to prune branches and leaves, kill insects and weeds.

After greenhouse vegetable planting, it is necessary to refine management, control temperature, and water more, and regularly fertilize to do a good job in pest management.
