What is the difference between growing vegetables in greenhouses and growing them in the open air?

Greenhouse cultivation is more expensive than open-air planting vegetables, but the production of greenhouse vegetables will be better than outdoor planting varieties and canopies, which can regulate temperature and humidity, and it is more convenient to manually control plant diseases and pests, and the planting cycle is short, and off-season vegetables can be planted, increasing the gap in the market, and the income will be better. Open-air planting should generally be suitable for vegetable planting according to the season, otherwise the vegetable planting is not good, or even not long. The open-air planting cycle will be longer than that of greenhouses, and the air temperature and humidity cannot be controlled, and there will be more pests and diseases, which will be difficult to manage, so I prefer greenhouse planting.

In a greenhouse, it's not just sunlight that keeps vegetables warm. There is a greenhouse effect in the greenhouse.

Photosynthesis of vegetables.

The photosynthesis of open vegetables cannot be achieved, so the quality of greenhouse vegetables is not as high as that of open vegetables, and the taste is good. Rich in nutrients. Greenhouse vegetables are not limited by the season and have a breakthrough time difference.

However, the yield and quality of vegetables cultivated in the open field are affected by rainy weather and threatened by high temperature and heavy rain in summer. What vegetables to grow in what season depends on the weather.

The quality is good, the open-air vegetables have a large temperature difference under natural conditions, a long time, an outdated appearance, a little more fiber, and a serious disability. Greenhouse production avoids these problems. The cost is relatively large in the north, the greenhouse ranges from 5,000 to 100,000, and the ordinary pipe shed in the south is about 10,000, and it is more than 30,000 to see what quality shed pipe, which is expensive and can be used for five to fifteen years.

Benefits, eating outdoors, the general output value is 3000 to 6000.

Year-round greenhouse production, planting winter, spring, summer and autumn medium and high temperature crops, the output value per mu is between 10,000 and 50,000, mainly relying on the thermal insulation capacity and technology of greenhouse facilities. The value of the commodity.

High, open-air, short cycle, complete goods, ** low. The greenhouse is manually adjusted, in advance or delayed, to control the market time, control the yield, and achieve the best quality and value. The nature of the work, strong outdoor seasonality, heavy workload in hot weather, no rain cooling equipment.

Greenhouses can do this. The production area can be planted by one person in the open air for five to eight acres. The greenhouse can be planted three to five acres per person.

The planting time is different, the taste is different, the length of the cycle is different, the general greenhouse planting vegetables, do not need to be planted in accordance with a certain season, and the open air planting should be planted in accordance with the appropriate season, otherwise it will affect the taste of vegetables, and its planting cycle is also relatively long for the temperature of the air, humidity is difficult to control, and there will be a lot of pests and diseases, the difficulty of management is relatively large, relatively speaking, greenhouse planting, there will be no such concerns.

The yield of greenhouse planting is relatively high, and the temperature in the process of planting is also relatively high, which may breed a lot of pests and diseases, **different, greenhouse planting, the management cost is relatively high, so the vegetables planted are more expensive, and the varieties of agricultural products planted are also relatively high-quality, and the management is more exquisite.

First of all, it is not the same, the vegetables grown in the greenhouse are more expensive, because the cost is relatively high, coupled with the usual care, the time is relatively long, and the vegetables grown in the greenhouse are generally dark green, which can be provided all year round.

Vegetables grown in greenhouses are not limited by the season, and have the ability to break the time difference.

the characteristics of spatial and geographical differences; The vegetables planted in the open air in the field are affected by rainy weather, and are affected by high temperature and heavy rain in summer.

Therefore, neither yield nor quality can be guaranteed, and it is up to heaven to decide what vegetables to grow in what season. Thank you for your interest.

1. The selection procedures of "greenhouse vegetables" are stricter than those of "field vegetables", and high-quality seeds naturally cultivate high-quality products.

2. Greenhouse planting vegetables is not limited by the season, and has the characteristics of breaking the time difference, space difference and regional difference; However, the vegetables grown in the open air in the field are affected by rainy weather, and the summer is threatened by high temperature and heavy rain, so the yield and quality cannot be guaranteed.

3. Planting "greenhouse vegetables" is better than "field vegetables".

In many rural areas, the "greenhouse vegetable" industry has become a new economic growth point and a new direction for adjusting the rural industrial structure. However, relatively speaking, greenhouse vegetables need high-tech and high-input support to have high output.

4. The demand for high-quality, pollution-free pollution-free greenhouse vegetables continues to grow in large quantities, and the demand for pollution-free greenhouse vegetables increases.

Extended information: Precautions for greenhouse vegetable planting:

1. Determine a reasonable planting time. The efficiency of greenhouse vegetables depends to a large extent on the early and late planting time, and the off-season vegetables are the highest benefit period before and after spring, and the planting time should be determined as the highest yield period before and after spring.

From the original annual stubble to the current 70% of the place with two stubbles a year, the planting period is roughly as follows: the planting period of one stubble a year is in early and mid-October, and the first stubble is in early and mid-July, and the second stubble is planted from December to January of the following year.

This is a high efficiency in terms of planting time.

2. Select high-yield and disease-resistant varieties. Improved varieties are the internal cause of increased yield. High-yielding cultivation techniques are first and foremost inseparable from improved seeds.

The use of greenhouse facilities to grow off-season vegetables relies on sufficient light and heat resources, mainly planting tomatoes, cucumbers, eggplants, peppers, beans, melons and other major categories of vegetables and fruits. The well-selected varieties generally increase the yield by 10% and 20%, and the benefit increases by more than 10%.

3. Reasonable shed type. Greenhouse is divided into 5 types, in the planting of vegetables to choose the type of shed according to the different requirements of vegetables for temperature, or according to their own shed type to determine the type of vegetables planted, only in this way can the ideal yield of vegetables be obtained.

Greenhouse vegetables are not affected by environmental weather factors, so you can grow off-season vegetables all year round.

Dapeng is definitely not as delicious as vegetables in the open air, and the open air receives the sunshine, these.

Compared with greenhouse vegetables and open-air vegetables, there are both advantages and disadvantages, the advantage is that the vegetables in the greenhouse grow fast, and the economic benefits are higher, but the disadvantage is that the taste of the vegetables is relatively poor, the nutrients are not sufficient, the most important thing is that because there are too many pesticides and growth agents, it is not healthy to eat too much!
