How to improve the technology of agricultural greenhouses to improve the yield and quality of greenh

It should be possible to ensure the temperature of the greenhouse, and it is also necessary to ensure that the greenhouse must have sufficient fertilizer and water resources, and must be watered and fertilized more, so that the yield of these vegetables can be higher.

Reasonable watering Keeping sufficient water is an important factor to ensure the normal growth of vegetables, and choosing a reasonable time period for watering and a reasonable amount of water is an important measure to improve vegetable yield, especially in winter.

When using greenhouses to grow southern vegetables, in addition to effectively controlling the temperature and humidity in the greenhouses, it is also necessary to scientifically select planting varieties.

Double-layer film can be used and disinfected in the greenhouse to kill pathogenic bacteria in the soil, and the way of film racking should be improved to enhance the photosynthetic effect.

We must choose the right plastic film, pay attention to ventilation and breathability, we must process the basic structure when we are in technical transformation, and then we should also pay attention to stability, and we must pay attention to the fertility of the soil.

After years of practice, I believe that the secret to high-quality production of vegetables grown in greenhouses is as follows:

Using the right greenhouse temperature has a big impact on the growth of vegetables. Now the most important technology for agricultural vegetable cultivation is the use of greenhouse film to grow vegetables, and the choice of greenhouse cover is very important. It is necessary to choose a greenhouse mulch film suitable for the climate at that time, so as to better control the temperature in the greenhouse and be more conducive to the growth and development of vegetables.

Moreover, in the process of choosing greenhouse coverings, greenhouse films made of non-toxic materials must be used for agricultural vegetable cultivation and the production of healthier vegetables. The light transmittance of the film is also very high. Be sure to choose the right light transmittance so that the vegetables get more sunlight and grow better.

The basic requirement for photosynthesis in vegetables is to control sunlight in the greenhouse. If you want vegetables to grow better, you have to give them proper light. Due to the weak holiday light in winter and spring, the film in the greenhouse blocks the sunlight.

Vegetables in greenhouses will be difficult to grow healthily due to lack of sunlight, resulting in slow growth of vegetables. Therefore, it is very important to provide adequate light for vegetables. We need to install well-lit lamps in the greenhouse to ensure better photosynthesis and healthy growth of vegetables.

In addition, the light time of vegetables also needs to be calculated, that is, in order to better promote the growth of vegetables, the amount of light must be controlled.

In order to ensure good ventilation in the greenhouse, carbon dioxide is also needed to provide the raw materials for the photosynthesis of vegetables. If the greenhouse is closed for a long time, the carbon dioxide in the greenhouse will be reduced, which is not conducive to the photosynthesis of vegetables and affects the growth of vegetables. Therefore, the greenhouse should be ventilated in time to make the vegetables have enough photosynthetic substances and better accumulate starch.

The type of vegetables in the greenhouse should be carefully chosen. When we grow vegetables in greenhouses, we must consider the influence of local climate, humidity and season on the growth of vegetables. If you don't consider the type of vegetables, it is likely that the vegetables will be difficult to survive, not only wasting time, but also wasting a lot of material costs, making it difficult to make a profit.

Therefore, we must introduce excellent vegetable varieties in order to better ensure the survival rate of vegetables and lay a solid foundation for the development of greenhouse vegetables in the future.

The above is the secret of high-quality production of vegetable greenhouse planting that I have summarized, and it is difficult to master these methods.

There is a secret, that is, when planting, you must pay attention to the air circulation inside, choose the right soil when planting, to fertilize, but also to pay attention to supplemental sunlight, in order to have a high quality.

Vegetables grown in greenhouses, if you want to dry quality, you need to refine planting, first of all, from the selection of varieties, planting time, but also from the environmental factors, so as to improve the quality.

The Ministry of Finance of the People's Republic of China on deepening the rural areas.

The integration of primary, secondary and tertiary industries, and the notice of the demonstration action of rejuvenating villages and strengthening counties through industry. Deepening the countryside.

The integration of primary, secondary and tertiary industries, the demonstration action of rejuvenating villages and strengthening counties through industry, cultivating and strengthening local economy and rural industries, and realizing the integration of production villages and production villages are important measures to promote industrial prosperity and urban-rural integration, and are of great significance to the implementation of the rural revitalization strategy and the acceleration of agricultural and rural modernization. Greenhouses have played an important role in the modernization of rural agriculture. With the increasing number of modern agricultural parks and family farms across the country, greenhouses have been widely used.

So the question is: why do modern facility agriculture make greenhouses? What are the advantages of greenhouses?

First of all, from the greenhouse. In the 90s of the 20th century, a Sanyuan Zhu village in Shouguang, Shandong Province, under the leadership of Secretary Wang Leyi, took the lead in planting warm vegetable greenhouses, which solved the problem of difficulty in eating vegetables in winter in northern China. At the same time, the vegetable planting technology greenhouse has been promoted to more than 20 provinces and cities across the country, which has completely changed the table vegetable culture in China.

At the same time, Shouguang has also developed into a vegetable planting base and vegetable base. At present, the greenhouse has developed from the earthen wall solar greenhouse to the spring and autumn multi-layer arch greenhouse, flower planting double-layer film multi-span greenhouse, vegetable planting single-layer film multi-span greenhouse, solar panel intelligent greenhouse and glass intelligent greenhouse.

1.Greenhouses can enable the production of out-of-season vegetables.

At present, the greenhouse can realize the early sale of spring crops and fruits, the postponement of harvest of autumn crops, and the production of vegetables in winter. The greenhouse realizes the year-round vegetables by staggering the vegetable production season, ensuring that people can eat fresh vegetable products on the table at any time.

2.Green pollution-free vegetable production in greenhouses.

By creating its own micro-environment climate (the vents of the greenhouse have insect nets), the greenhouse can isolate pests and diseases to the greatest extent and reduce the damage of outdoor dust and smoke to plants. At the same time, greenhouses can reduce the damage to crops caused by natural disasters and produce high-quality and pollution-free vegetables.

3.Greenhouse is highly efficient and energy-saving.

In winter, natural light energy is effectively used to produce high-quality out-of-season vegetables. The greenhouse uses transparent covering material, which heats up quickly and has good light. In the greenhouse on a sunny day, the indoor temperature is more than 20 degrees higher than the outdoor and 2-3 degrees higher at night.

Since the optimal temperature for vegetable production is 20-30 and the minimum growing temperature is at least 5-8, winter vegetable production can be done in greenhouse facilities. The temperature difference between day and night in the greenhouse is large, the nutrient production cycle is long, and the quality and yield of watermelon, melon, fruit and vegetables produced have been greatly improved.

4.Greenhouses can be mechanized.

At present, the vegetable greenhouses built in recent years can be combined with the Internet of Things control software system to realize the intelligent and automatic control of the greenhouse's shading, ventilation, cooling, heating, irrigation and fertilization systems. The greenhouse can be monitored in real time through mobile phones and computers, which can save water, fertilizer, electricity and energy while reducing labor.

Greenhouse facility agriculture is a high input, high output, high efficiency of the industry, only the formation of a considerable scale, is conducive to standardization, standardized production, in order to form an influential brand, so as to occupy the market, so that the resource advantage can be effectively developed and sustainable utilization, while bringing huge economic benefits. Therefore, on the basis of good planning, all levels should formulate preferential policies, increase investment, support and cultivate large-scale greenhouse agricultural bases, accelerate the development of facility agriculture and enterprises, and promote the industrialization of greenhouse facility agriculture Greenhouse agricultural engineering standardization and standardization, including greenhouse facilities, equipment and agricultural production. With specifications and standards for the design, structure, installation, construction and use of facility buildings and supporting facilities, construction and operation costs can be greatly saved; Facility agricultural production has established norms and standards, reduced the production cost of agricultural products, and can improve the quality and sales income of agricultural products in greenhouses.

Greenhouse does bring a lot of help to the development of agriculture, it also has drawbacks, many vegetables in the greenhouse are fast-forming vegetables, such vegetables have a certain harm or unhealthy to the human body for a long time.

The disadvantage of greenhouse planting is that the light in the greenhouse is insufficient, and the temperature difference between day and night is not large, which leads to the taste of the vegetables planted is not so good, and if the greenhouse planting is not good, the temperature will lead to a large number of insect pests.
