If a greenhouse is built in the countryside, which crops can be planted more quickly?

The facility off-plan is divided into solar greenhouse off-plan and plastic greenhouse off-plan. There are many fruit trees and fruits grown in the greenhouse, and this labor-intensive vegetable is more or less profitable. The food grown in the plastic greenhouse is more miscellaneous.

I am more optimistic about the cultivation of plastic greenhouses. The investment is not much, the speed is fast, but it is only because of the vigorous development of greenhouses in the past few years that people have overlooked some plastic greenhouses. It would be better if the vegetable base is close to the city center.

Growing a few leafy vegetables is not a problem at all. Our plastic greenhouses here are mainly leafy vegetables, and the most grown leafy vegetables are celery, kale, cauliflower and lettuce. Briefly introduce their cultivation methods, and if you are interested, you can give it a try.

Celery is the most leafy vegetable planted in plastic greenhouses, and better varieties should be selected in plastic greenhouses, usually American celery, Tianjin solid celery, four seasons celery, etc. Growing celery requires loose and breathable soil, and the amount of fertilizer for celery is relatively large, and 5,000 kg of rancid fertilizer is usually put when stopped. Celery stumps in plastic greenhouses can be scheduled earlier or later in the spring.

If the spring is early, it is generally the seedling in mid to late January, the seedling age is about 90 days, the planting begins in mid-April, the harvest begins in mid-June, and the planting is carried out, the meter width, the Gru row spacing is 8 cm * 10 cm, and the harvest is in June. In autumn, seedlings are usually cultivated in mid-June, officially eaten in late August and early September, and certificates are harvested in the spring season.

Celery prefers cold climates, and it is easier to plant crop rotations in the fall. For celery to grow well, water and fertilizer must be in place. Generally speaking, one month after formal consumption, celery needs to enter the rapid growth period, it takes about 10 days to pour a small amount of water, and when the wind is not turned on, it needs to be watered once every 20 days, and the water is filtered once to make the water fertile, usually chasing 15 kg of nitrogen fertilizer per mu.

Cultivating mushrooms in plastic greenhouses is relatively simple, and the propagation method of mushrooms is also relatively simple, easy to manage, adjust the temperature, and can be harvested about 6 or 8 times a year. Oyster mushrooms are planted by scientific methods, about 30 kilograms of oyster mushrooms can be produced per square meter, and about 10,000 kilograms of oyster mushrooms can be produced per acre of greenhouse every year. In order to make the side ears grow better, you can cover the plastic film of officialdom with a double curtain to properly cover the light.

In order to increase the yield, it is necessary to select the original species of the mushroom that is grown. First of all, it is necessary to introduce strains from various units, and after a certain amount of engineering review and processing, the best ones should be selected. There are many types of strawberries, which can be divided into ordinary strawberries, cream strawberries, chocolate strawberries, etc., and the different types of ** are completely different.

The market for creamy strawberries** is about 3 times that of ordinary strawberries, and they are tall and sweet. The ability of strawberries to adapt to the environment is relatively high, and the picking time is relatively long, which can be picked until May, and the yield per mu can reach about 1000 kg. If calculated according to the average sales of 30 yuan per kilogram, the income per mu is about 30,000 yuan, which is several times higher than planting ordinary strawberries, and the profit is considerable.

The biggest advantage of the constant temperature greenhouse is the constant temperature, which can plant crops out of season, so there are now two planting methods: the first one: vegetables, planting loofahs, cucumbers, beans, tomatoes and other crops with high yield and high benefits, these crops have a short growth cycle, which is conducive to the timely adjustment of the planting scale.

The second type: fruits, you can choose several seasonal and out-of-season fruits that are more strict with temperature conditions and have relatively high yields.

In our lives, we have built a constant temperature greenhouse in the countryside, which crops can be planted more quickly? Some people say that the biggest advantage of greenhouse planting is that it is planted out of season, which I believe many people will not oppose. In the season when vegetables and fruits are scarce, greenhouse fruits and vegetables have become the preferred choice of consumers.

Out-of-season fruit and vegetable planting in greenhouses can not only avoid the concentrated time of fruits and vegetables on the market, reduce sales pressure, but also realize people's wishes to eat the same fruits and vegetables in different seasons. The strawberry market is now becoming more and more popular year by year, and strawberries not only have a variety of ways to eat, but also have a broad market prospect for processing. However, now the most popular is the greenhouse strawberry tourism and picking service, many people are willing to use their leisure time to go to the greenhouse strawberry farm to experience the fun of strawberry picking, so this project has also led to the development of tourism in many places.

Shiitake mushrooms are nutritious and loved by consumers, in recent years, the first class of shiitake mushrooms is still relatively stable, plus shiitake mushrooms can be made dry, which is also one of its planting advantages, when we plant shiitake mushrooms, you can plant several more varieties, such as oyster mushrooms, enoki mushrooms, straw mushrooms, etc., so that several incomes, higher profits. Calcium fruit is a fruit with very high calcium content, and the planting area of calcium fruit in China is not very large, and the market is also considerable, so it has great development potential. In addition, calcium fruit has the characteristics of strong adaptability, fast growth and high yield, and the planting prospect is still very impressive.

Ordinary 832 conjoined film greenhouse span 8 meters, spacing 4 meters, the cost of a shed is between 10,000-20,000 Now it is more suitable to plant vegetables The supply of vegetables in the south is soaring.

Golden leeks, silver cucumbers, from the older generation to say so, has always been this way, our greenhouse is planted cucumbers, sold to a pound during the New Year, more than three yuan in March has been maintained for a long time, this year's weather is cold, southern vegetables have not come down, so this year's vegetables have been high, supermarket dishes are three or four dollars a pound, hey, can't afford to hurt.

Greenhouse cost: 15 yuan per square meter of cost - 25 yuan planting project recommendation:

Tulip flowers. There are about 3 seed balls, 13,000 --- 15,000 plants in a greenhouse, and 10-16 can be sold.

Succulent. There are many types, each ** is different, but the price difference can also be 20-40 yuan.

Fruits and vegetables. For example, strawberries and the like have greenhouses, and they are sold in all seasons. Consumer goods, fast turnover.

Greenhouse, also known as conservatory, refers to a room with facilities such as cold protection, heating and light transmission for cultivating temperature-loving plants in winter. In the season that is not suitable for plant growth, it can provide growth period and increase yield, and is mostly used for the cultivation or seedling of plants such as vegetables, flowers, and forest trees in the low temperature season. A greenhouse is a building that can control or partially control the environment in which plants grow.

It is mainly used for non-seasonal or non-regional plant cultivation, scientific research, generation breeding and ornamental plant cultivation.

There are a few aspects:

First, the greenhouse can ensure the temperature in winter and can carry out the off-season production of vegetables.

Second, because the greenhouse is planted in a protected area, it is generally covered with plastic film, so it can effectively prevent pests and diseases.

The third is to apply efficient production technology in the greenhouse, which has good durability and is protected by greenhouses, so it is protected from external wind, cold and light.

The first is to use a covering to reduce humidity. Lamination can reduce the evaporation of surface water into the shed, which is an important measure to reduce the air humidity in the shed. Use the dust method and smoke method to prevent moisture.

The dust method and smoke method can avoid increasing air humidity due to spraying and improve the prevention and control effect. Cultivation dehumidification. By cutting off the soil capillary, you can prevent the soil capillary water from rising to the surface layer and avoid the evaporation of a large amount of soil moisture.

Secondly, according to the different temperature requirements and growth habits of different crops, the corresponding greenhouse facilities should also be changed accordingly. Solanaceae crops (eggplant, peppers, tomatoes, etc.) and melon crops that require high growth temperature need to be cultivated in double-shed four-film greenhouses in the cold winter, otherwise they are easily affected. Cold.

Crops grow slowly, and fruiting is difficult. If there is a long period of cloudy and sunny weather, the ventilation time should not be too late, and only one side of the ventilation, the effect of this is to prevent the crop branches and leaves from losing water and wilting.

The second is to grasp the temperature control. In addition to simple facilities such as small and medium-sized arches, solar greenhouses and plastic greenhouses have a construction area of more than 2 million hectares. A greenhouse is an energy-efficient building that makes full use of solar energy.

The roof inclination in the greenhouse design fully considers the incidence angle of the sun, which can not only maximize the use of sunlight to heat the greenhouse, but also ensure the normal photosynthesis of indoor crops. The rational use of sunlight and light and heat resources in the greenhouse ensures the normal production of vegetables and other horticultural crops, and also makes a great contribution to eating fresh vegetables in the northern winter.

Finally, the frame film material should be replaced in time。Using iron wire instead of bamboo poles and bamboo chips to support agricultural films, and using plastic ropes instead of bamboo poles as climbing objects can effectively reduce the shading, increase the greenhouse light intensity by more than 10%, increase the greenhouse temperature by 1 -2, and significantly improve the photosynthetic efficiency of crops. High mountain ridges have a large surface area, receive more sunlight during the day, and absorb more heat from the air, so the temperature rises faster.

But the ridge should not be too high or too wide, generally 15-20 cm high and 30 cm wide.

I think that if you want to build a greenhouse, you must first pay attention to the temperature and light time inside, and the color of the shed selected by different crops is different, and the light should be kept inside at any time, and the temperature should be adjusted, which is more conducive to the rapid growth of plants, and it is necessary to pay attention to fertilization and maintain soil fertility.

First of all, you must choose open land, then you must choose a place where the sun rises, and then you must bring a glass greenhouse, there must be windows, so that you can play the role of heat preservation, and you can also open windows when you need to, which can reduce the temperature.

First of all, it is necessary to choose open and flat land and build a greenhouse on a gentle slope of the rising sun. Do not build greenhouses at the tuyere, so as not to damage the greenhouses due to strong winds.
