Is it okay to grow pumpkins in greenhouses in winter?

Pumpkin to be erected yield can be increased, there is this powdery mildew.

Pumpkins are planted in greenhouses in winter, and the basic conditions required for their growth should also be met, so that the pumpkins will bear fruit. Pumpkins are temperature-loving, short-day plants that are drought tolerant and less demanding on the soil, but are preferable to fertile, neutral or slightly acidic sandy loam.

Pumpkin, Cucurbitaceae.

A species of the genus Pumpkin, an annual creeping herbaceous plant.

The stems are often rooted, the petioles are stout, the leaves are broadly ovate or oval, slightly soft, the veins are raised, the tendrils are slightly thick, monoecious, the fruit peduncle is stout, with ridges and grooves, varies from variety to variety, there are often several longitudinal grooves or none outside, the seeds are numerous, oblong or oblong.

It is native to Mexico to Central America and is commonly cultivated all over the world. It was introduced to China in the Ming Dynasty and is now widely cultivated in the north and south. The fruit can be used as a substitute for food. Each part of the whole plant is used for medicine Xunkuan, and the seeds contain pumpkin seeds.

Amino acids, which have the effect of clearing heat and dehumidification, and repelling insects, have the effect of schistosomiasis.

It has the effect of controlling and killing, the vine has the effect of clearing heat, the guati has the effect of stabilizing the fetus, and the toothache is **.

Thank you for your guidance! Now with the improvement of living standards, the material has also improved. Although the cold resistance and high yield are high, the product is not welcomed by the market, while the cucumbers from the white south yellow pumpkin seeds are shiny and popular with consumers.

Thanks for the invite. Cucumbers occupy a wide range of planting areas in China. With the advent of greenhouse cultivation technology, cucumbers can be seen on our tables all year round.

Although there are greenhouses, the ground temperature is low in winter, the root system of the plants is underdeveloped, and some diseases will also appear. Therefore, when choosing cucumber varieties, pumpkin seedlings are generally grafted, the principle of strong cold resistance, strong disease resistance, generally choose black-seeded pumpkin, black-seeded pumpkin anvil missing chain when the ground temperature drops to about 10 degrees Celsius, the root system can still maintain a certain absorption capacity.

Cucumbers are generally grafted with pumpkin as rootstock, mainly to improve disease resistance and increase yield, and the most effective way is to solve it through grafting. In the selection of scion, choose cucumber varieties with good stool quality and high yield. The best grafting period is when the first true leaf is half-spread to full.

The rootstock is sown 13-15 days before grafting, and the scion is sown 16-20 days before grafting. It is necessary to strictly prevent the growth of rootstock and scion seedlings. You can choose to use the docking method.

After the grafting is completed, the seedlings should be moved to the nutrient bowl immediately, and the root systems of the two should be properly separated during transplanting, so as to facilitate the root breaking treatment of cucumber in the later stage. Water in time after planting.

Thank you very much for the invitation of today's headlines, there are thousands of acres in our greenhouse, so that we have been planting ourselves for more than 20 years, the annual cucumber planting season is autumn and winter, basically that autumn, cucumber seedlings generally do not need to be grafted, melon seedlings need to be grafted.

Let me tell you about some details of this cucumber seedling grafting problem, first of all, the time of grafting must wait for the cucumber seedlings to grow to almost two leaves, you can choose pumpkin seeds, pumpkin seeds must be selected when the tooth rate is high, the general germination rate is relatively high can reach about 85%, and even some pumpkin seedlings can reach 90%, this pumpkin seed does not say that it is specially cold-resistant, salt-alkaline resistant seeds, So when you buy it, you only need to pay attention to what his teething rate is, and you don't need to pay attention to whether it is cold resistant and Korean alkaline, because there is no paper and this kind of pumpkin seeds have not appeared.

First of all, I have talked about the growth of cucumber seedlings above, and secondly, the growth of pumpkin seedlings When the pumpkin seedlings grow to two petals, they must be grafted, because this is a matter of time, as long as the pumpkin seedlings grow to two and a half, you must graft, you can't wait, you can't delay, you can't let the pumpkin seedlings grow very tall, because its stem will have mucus at this time, when you grow big enough, it will have less mucus if it grows high, At this time, if you graft it again, it is not easy to have a bite, and it is not easy to graft together with cucumber seedlings. When the pumpkin seedlings are seeded, they must face the roots of the cucumber seedlings, and they must not be far apart, because if they are far apart, the two of them are not easy to graft.

Finally, all grafting will be depleted, so when you need cucumber seedling grafting, you must raise more, so that it is more sufficient, well, if you have any other questions, you can pay attention to me and send me a private message, our family has been planting greenhouses for more than 20 years, which may help you to a certain extent.

It is possible to grow strawberries, and the soil of strawberries is adaptable and very easy to survive.

Yes, it shouldn't make a difference.

Now it's also possible to grow baby pumpkins in greenhouses.

The weather is warm, and you can remove the greenhouse after a while.

This can be done a little earlier than the regular baby pumpkin on the market.

Ordinary Beibei pumpkins are worth about 10 yuan each, and real Beibei pumpkins are worth 50 yuan each.

Pumpkin is a temperature-loving and heat-tolerant vegetable, which stops growing below 10 degrees, and cannot tolerate low temperatures below 5 degrees for a long time, let alone frost.

The temperature in the greenhouse must not be too low, let alone below zero.

The temperature and precautions for planting eggplants in greenhouses are as follows:

1. Seed selection and breeding: Eggplant planting in winter and spring greenhouses should be selected with excellent varieties of cold resistance, strong disease resistance, high yield and market prospects. Before sowing, build a seedbed (you should choose a plot with dry, ventilated, well-drained, and no eggplant vegetables in the previous crop), and configure nutrient soil (seedbed soil:

Decomposed organic fertilizer: compound fertilizer =, evenly mixed), and poured with foot water; Seed treatment, remove the deflated grains, put the seeds into 50-60 hot water (three open and one cool) and stir continuously until about 30, and then let stand for 8-10 hours and then spray 800 times of the new high fat film and mix well; Seeding: Evenly sprinkle the treated seeds in the seedbed, the sowing amount is appropriate, cover the soil with 1-cm thick nutrient soil after sowing, and spray the new high-fat film to keep warm and moisture to increase fertilizer and promote the emergence of seedlings.

2. Transplanting and planting: Prepare the land for furrowing, and the base fertilizer should be applied half a month before planting, so as to ensure that all kinds of elements are reasonably matched. Water your feet.

Plan the furrow, lay out the row spacing of the plants, and plant reasonably (generally planted in December). Cover film insulation: In winter, when the temperature is low, it is necessary to use two sheds and three films to cover, and spray new high-fat film on the ground and plants to keep warm and protect moisture and prevent diseases and insects.

According to the temperature change, it is necessary to transmit light and cool down in a timely manner every day, and the temperature in the shed should be kept at about 25. Fertilizer and water management: After planting, water and fertilizer should be reasonably controlled according to temperature changes and growth and picking conditions to ensure balanced and sufficient nutrition.

3. Promote flowering and fruiting: After the plant finishes slowing down the seedlings and returns to normal development, it is necessary to spray Kao No. 3 in time, which can effectively inhibit the wild growth of the main shoot and side buds, promote the differentiation of flower buds, more flowering, and more fruit set. It is necessary to spray vegetable fruit at the bud stage, young fruit stage and fruit expansion stage to thicken the fruit pedicle, improve the circulating fruit setting rate, promote fruit development, and have no deformity and no fruit drop.

Fourth, pest control: the main diseases of winter greenhouse eggplant are: Verticillium wilt, sclerotinia sclerotinia disease, cataplexy, fruit rot, brown streak, virus disease, etc., to choose a highly targeted agent (such as DT50%, chlorothalonil wettable powder, agricultural streptomycin, etc.) + new high lipid film 800 times liquid can be effectively controlled.

Liaoning winter greenhouse planting eggplant temperature reasonable measures are enough, the measures are as follows:

Increase the mulch at night around the greenhouse around the grass or corn stalks, than without mulching can be increased by 1 2, on the original grass and then add a layer of toma, can make the temperature in the greenhouse increase 2 3. Alternatively, a film can be added to the original grass to prevent the wind and prevent rain and snow from wetting the grass and reduce heat loss due to water evaporation.

Before the cold snap of smoke around the greenhouse arrives, lighting smoke around the greenhouse can prevent the heat around the boron from radiating to the air and reduce the heat loss.

Frequently clean and scrub the greenhouse film to remove the dust, dirt and snow on it in time to increase the light and increase the temperature of the shed.

Covering plastic film or small arch shed greenhouse belongs to high ridge cultivation, can be covered with a layer of plastic film on the high ridge, generally can increase the ground temperature 2 3, flat furrow cultivation, can support small arch shed to increase ground temperature.

The cold ditch is dug on the south side of the outside of the greenhouse and filled with grass, horse manure, straw and other insulation materials to prevent the ground temperature from being lost outward, which can improve the ground temperature in the south of the greenhouse.

The double-layer film is covered under the non-drip film, above the wire of the sling, and another layer of film is laid. Due to the presence of air in the middle of the space, the temperature in the shed can be significantly increased. 7.

Use the storage tank to store heat in the greenhouse** dig a storage tank every few rooms, spread plastic film on the bottom of the pool, and then fill it with clean water, and cover the upper part of the pool with a layer of transparent film. The heat absorbed during the high temperature in the middle of the day can be released in the evening. Finally, it should be noted that firewood and grass should not be used to heat up the temperature in the shed, because the smoke emitted when firewood and grass are burned is extremely harmful to vegetables.

Pumpkin cultivation technology in greenhouses.

Colonization. Due to the large differences in climate in various places, the planting time of pumpkin is also inconsistent, as long as it can ensure that pumpkin seedlings are not damaged by low temperature freezing and grow normally, they can be planted or live-seeded. It should be noted that the planting should not be too deep, and it is advisable to expose the cotyledons to the ground.

When watering the root water, do not get water and soil on the seedling leaves, so as not to affect the seedling and survival.

Cultivating and weeding. Combined with weeding for medium cultivation, from shallow to deep. Be careful not to move seedlings and injured seedlings or roots when weeding.

In order to promote the development of the root system, when cultivating, soil should be cultivated on the roots. During the whole pumpkin growth period, it is generally necessary to carry out weeding 2 3 times. Be careful not to damage the pumpkin plants and leaves during tillage.

Irrigation top dressing. After the pumpkin is planted, if the moisture is good, it generally does not need to be irrigated. At this stage, tillage should be carried out many times, and at the same time, the ground temperature should be increased to promote the development of the root system, so as to facilitate the growth of seedlings.

After the vine is extended, 15 20 cm away from the root, ditching and fertilizing, applying decomposed manure, and spraying photosynthetic nutrient fertilizer film to improve photosynthetic capacity nutrients and chlorophyll, which can help plants absorb a lot of light energy and light to supply plant growth and development.

Pruning and pressing vines. When cultivating pumpkins, sometimes, due to the excessive branches and leaves, it is easy to cause melons to fall. Therefore, it is generally recommended to spray Kao 3 to inhibit the growth of the main shoot, bloom more, set more fruits, and promote the development of pumpkin.

If there are special cultivation needs, pruning and leaving side vines should be carried out as needed.

Pollination. If pumpkin is cultivated in a facility or in the open field (rainy days during flowering), in order to improve the pumpkin setting rate and yield, and prevent stiff buds and stiff fruits, it can be sprayed to promote Kao No. 3 to improve the quality of pollen fertilization and increase the yield of pumpkin.
