What should I pay attention to when cultivating zucchini in a solar greenhouse?

The optimal temperature for seed germination is 20-30, germination is slow and regular at 20-25, but it cannot germinate below 13, and the germination rate decreases above 35. The optimal temperature for seedling growth was 18-22 during the day and 8-12 at night, and the optimal temperature for flower bud differentiation was 20 during the day and 10 at night. The optimal temperature for flowering and fruiting is 22-25, and the pollination and fertilization effect is poor when it is lower than 15 and higher than 35.

The optimal temperature for photosynthesis is 20-30. A temperature of 13-15 at night can promote the movement of light products, and 8-10 fertilized fruits can swell. The optimal ground temperature for root growth is 20-22, the starting temperature for root hair formation is 12, and the minimum tolerable ground temperature is 6-8.

In order for the seedlings to grow neatly, the method of moving the seedlings should be employed. Large seedlings should be placed on the south side of the greenhouse seedbed, and small seedlings should be placed in the middle of the seedbed, where the light and temperature are better. When pouring seedlings, the spacing between seedling pots can be appropriately increased to make the seedlings neat and robust.

Zucchini is mainly composed of main vines and melons, and the side branches should be removed as soon as possible; Zucchini has large leaves and long petioles, which make it easy to shade. Diseased leaves, yellow leaves, residual leaves, and old leaves should be removed as soon as possible to promote ventilation and light transmission and prevent disease infection. The production of zucchini in solar greenhouse is still in the trial stage during the sowing stage, and the cultivation system has not yet been formed.

According to early spring cultivation, it takes about 60 days from sowing to harvesting. Due to the low temperature and weak sunlight in winter and spring, the growing season will inevitably be extended. Seedlings with cotyledons are first made into a sand bed on the floor of the greenhouse, and seeds with small buds are sown on the bed surface and watered with water.

When the two ** leaves are in 2-3 days, plant into the seedbed with a row spacing of 10-12 cm. The method is shown in the cucumber seedling section.

Moisture managementZucchini seedlings are prone to overgrowth. In addition to strict temperature control, moisture must also be strictly controlled, so that there are no early phenomena and no watering is required. When watering is required, it should be done in the morning when the sun is sufficient, and the amount of watering should not be too large.

After watering, ventilation should be strengthened. Increase the light intensity. Erect a reflective curtain north of the seedbed to increase the light intensity.

It is conducive to the differentiation and development of female flowers and inhibits the excessive growth of seedlings. We should pay close attention to the cultivation of seedlings and lay a good foundation for a variety of melons. The amount of water to promote seedlings should not be too large, especially when the ground temperature is low, it is easy to take root.

When the melon seedlings grow up, they should squat down until the first melon grows to more than 10 cm, and then they can be fertilized and irrigated. The flowering period of zucchini requires high light intensity. Zucchini grown in solar greenhouses in winter and spring is in the season when the light is weakest in severe winter.

Even when the temperature is met, it tends not to bloom.

In the process of growing zucchini, we should reasonably regulate the indoor light according to the changes of the season, the solar greenhouse in our village adopts the architectural format of high north and low south, so that the greenhouse is fully sunny, and try to enhance the role of light.

Generally, from late September to early October, sowing in a solar greenhouse, grafting seedlings, planting from the end of October to the beginning of January, harvesting from late January to mid to late May, and the harvest period is about 210 days.

We should pay attention to pests and diseases, because pests and diseases at this time are very serious and seriously affect people's health, so we should pay attention.

In the early or late fruiting stage, the environmental conditions of the female flower formation process are relatively poor (the temperature is too high and too low, the water is uneven, etc.), and the female flower development is incomplete, which directly causes the fruit to be deformed and the proportion of fruit is high. For example, low temperature during the flower bud differentiation period can easily lead to the occurrence of deformed fruits. The situation you mentioned, my family has also encountered it.

Let's talk about the situation in our family. Causes of deformed fruits. That is, we have seedlings too early, the temperature is too low, and the seedlings are damaged.

After transplanting, there will be deformities, and the yield will be very low.

Even dead seedlings. Therefore, when we buy seeds or seedlings, we must understand whether they are suitable for your area, because zucchini varieties consider many factors such as temperature and light in the breeding process, and it is naturally easy to cause melons or deformed fruits if they are not in suitable areas. Deformed melon In the process of zucchini production, various deformities often occur, which seriously affect the quality and yield of zucchini, and cause great losses to vegetable farmers.

There are the following points for turning melons. First, poor flower bud differentiation or pollination leads to the inability to produce auxin in the ovary, resulting in zucchini melon. In view of this situation, the means of wiping melon can be used to supplement auxin for the fruit, promote the sitting of melon, and prevent melon.

Deformed bee sirlums can also appear. After on-the-spot visits and consulting various information, it was learned that in fact, the sudden drought is the land with a relatively high salinity concentration, as well as the absorption of various nutrients, insufficient water, and insufficient light will cause the situation of zucchini peppermelon.

There are many influencing factors. It may be the variety of air sunlight pesticide residues. Seasonal factors .......

Another is whether it is short of water. This is critical. If you want to improve this problem, it is not something that can be explained clearly in one sentence or two.

This also requires long-term experience.

It is because sunlight exposure and good environmental ventilation are good for the zucchini grown, and the zucchini grown in this way will be particularly productive.

A: Because the quality of ventilation and light transmission conditions will affect the growth and development of zucchini, I think growers should pay more attention to this.

Because as long as there is enough ventilation and light, the gourd seedlings will grow and develop better, and its gourd seedlings will thrive.

In addition, zucchini prefers temperature but is not heat-resistant, its growth period is relatively long, generally one month can bear fruit, if the fertilizer and water conditions are good, you can pick two or three months, therefore, you should avoid high temperature as much as possible when planting. Zucchini is more hardy and not resistant to high temperature vegetables, the most suitable temperature for growth and development period is 20-25, 15 below the slow growth, 8 below the stop does not grow, more than 30 slow growth and willing to get virus disease, seed germination temperature 25-30, then in the off-season planting vegetables, open field generally can not be planted, the outside temperature is relatively low, only to take greenhouse planting, in order to grow more high-quality vegetables. For example, we eat peppers, tomatoes, eggplants, cucumbers, and many more in winter.

Zucchini planting is generally before and after Qingming, watering first, digging a pit 5-6cm at the dry point, and burying the seeds in the soil. Thanks for the reference. The local area is different, and it is generally possible to have a minimum temperature above 12!

Some crop temperature requirements are different depending on what adaptability is carried Zucchini is a cultivar of the Cucurbitaceae squash species with white spots on the leaves and 5-edged fruit stalks, he is actually a kind of pumpkin, also known as American pumpkin. When I went to Xinjiang in 2018, I saw a large area of zucchini planting, but it was not used to harvest tender melons, <>

Too good first-class soil is too rich in nutrients, which will lead to less seedlings and melons, and generally choose thin land and two depressions to plant zucchini. Because dry land does not protect seedlings, if the rain in the later stage of waterlogged land will lead to rotten melons, which is also a reason for the reduction of the yield of many kinds of zucchini. The plot where zucchini is planted should be selected in a place with good sunlight, good water supply and drainage, and strong permeability.

The soil in which it is planted should be loose and have good moisture content. After deep ploughing of the plot before planting, a sufficient amount of farm manure is applied.

We need to select high-quality varieties, then carry out sowing, reasonable fertilization and watering after the emergence of seedlings, and carry out management measures for flowering and fruiting in the later stage. Varieties should be selected to be resistant to high temperature, drought and waterlogging, good virus resistance, easy fruit set, and high yield.

When planting gourds, you need to pay attention to the emission measures in the field. It is necessary to pay attention to insect control, pay attention to strengthening nutrition, and pay attention to drainage and irrigation when there are many rainy seasons, so as not to cause root rot caused by rainwater.

Zucchini's requirements for soil are relatively strict, of course, its environmental requirements for growth are very strict, but if you want to grow zucchini well, then the correct soil selection is the basis for high yield and high quality of zucchini. It is best to plant zucchini in the soil with strong water storage capacity and close to the water source, followed by the nitrogen content in the soil should not be too high, and the soil layer is best to be pine and solid, which is conducive to the growth and water storage of zucchini roots.

Zucchini is very sensitive to temperature, if the temperature is higher than 30 degrees or lower than 15 degrees, then the growth rate of the plant will slow down, the resistance will decrease and various diseases will easily occur, but if the temperature is lower than 10 degrees, then the plant will directly stop growing, so the temperature has a great impact on the growth of zucchini.

Zucchini is extremely drought tolerant, if the moisture in the soil is not up to standard, then the growth of zucchini will slow down, onset and even wilt, so we should water in time.

soil, temperature, etc. Soil, zucchini is very strict on the soil, it is best to choose a place close to the water source; The temperature, the temperature at which the zucchini grows properly is between twenty and twenty-five degrees.

Temperature

Zucchini is very fragile to temperature, if the temperature is higher than 30 degrees or less than 15 degrees, then the growth rate of the plant will slow down, the resistance will decline and it is easy to produce various pests and diseases, but if the temperature is less than 10 degrees, then the main stem will stop growing, so the temperature is still very harmful to the growth of zucchini, the most suitable temperature for the growth of zucchini is about 20-25 degrees, Therefore, it is necessary to be aware of the temperature change at the time of planting and effectively control the temperature using the manual planting process.

Plucking

In the whole process of zucchini growth, special attention must also be paid to some of its unnecessary branches, branches and petals in a reasonable period of time to pick off, the effect of that is to improve the production, sales and quality of zucchini, because the branches are too luxuriant, then the permeability in the field is not good, easy to concurrency, and the nutrient loss is too large to completely meet the requirements of the fruit, resulting in the reduction of the quality of zucchini, and then some petals and branches around must be cut off, so that a good melon will grow better.

Fertilize. The production and sales of zucchini and the quality of nutrients are particularly harmful, in the whole process of zucchini growth must be specifically based on potassium fertilizer, if the soil has nitrogen components then most of them do not need to apply base fertilizer, if not then only a small amount of application, because the base fertilizer is too much will cause zucchini to grow steeply seedlings and not bear fruit, and then miss the best fruit setting period to cause limited yield, but it has a very large demand for potassium fertilizer, potassium fertilizer can promote the blooming of flowers and carry out flower preservation, and at the same time can also add appropriate boron fertilizer for strong melon.

More nitrogen and less potassium

Zucchini's requirements for nitrogen, phosphorus, and potassium are the most abundant in potassium, followed by nitrogen, and phosphorus at least. The temperature in early summer is already high, and if there is too much nitrogen fertilizer, it is easy to cause the zucchini to grow steeply. Therefore, top dressing must pay attention to less nitrogen fertilizer, with high potassium compound fertilizer as the dominant fertilizer.

Prevent high temperatures and droughts

Zucchini is not tolerant to high temperatures, and high temperatures and droughts will not only reduce their production, but may also cause viral diseases. Today's temperature is high, if natural ventilation and watering are not timely, it is very easy to lead to high temperature and drought of the arch shed, leading to the occurrence of viral diseases. In addition, the temperature of the arch canopy increases, and the zucchini is very prone to steep growth, resulting in melons.

Therefore, it is necessary to enhance natural ventilation and water immediately to prevent the arch shed from producing a high temperature and drought environment. Under normal conditions, the temperature of the arch shed should be adjusted at 20-24 during the day and 12-14 at night. Water immediately in times of drought, and properly plough the soil after watering.

Avoid falling flowers and fruits

Artificial assisted pollination is carried out at 6-8 o'clock in the morning every day, and the male flowers are removed, the pistils are exposed, and the female flower column can be rubbed twice. Auxin solution can be sprayed or dipped in the newly blooming female flowers with a solution containing 20-25mg per liter or a solution containing 30-50mg per liter to prevent falling flowers and fruits.

Avoid too many results

In the ripening period of zucchini melon to avoid too much fruit and falling seedlings, generally with 2 leaves and 1 melon as the suitable amount of fruit to carry out combing, in the future to immediately hit the yellow leaves, diseased leaves, in order to promote wind and light permeability, improve efficiency.

We must pay attention to the temperature of planting, grasp it at about 25 degrees, and we should also choose high-quality seeds, we must pay attention to the density of planting when planting, we should pay attention to the depth of planting, and we should also do a good job in ventilation and water and fertilizer management, and we should use chemical fertilizers and pesticides in time.

It is necessary to pay attention to the selection of soil, to control the temperature at about 12, to pay attention to the choice of fertilizer, to pay attention to the time of top dressing, and to pay attention to the way of cultivation.

When planting zucchini, we must choose the right soil, choose the right site, and pay attention to proper watering, pay attention to pest and disease prevention, and be sure to properly fertilize in the later stage.

To prevent diseases, and at the same time to prevent viral diseases, but also to control the temperature, it is necessary to pollinate manually, and master the planting technology.
