What preparations do rural areas need to make before preparing for greenhouse planting?

After planting vegetables, farmers often report uneven emergence, wilting, and dead trees. This is probably because the planting is not done well. Therefore, it is necessary for farmers to do a good job in every aspect of the planting process to minimize problems in the later stage.

Keep these points in mind when growing vegetables in a greenhouse!

1. Preparation before planting.

1.Shed and soil disinfection.

Before growing vegetables, the greenhouse needs to be disinfected. Fumigation can be used. About 3 cm of sulphur is used per acre of land. After ignition, the shed is closed, and the smoke is exhausted after 24 hours; It can also be used with 45% chlorothalonil 200 250 grams of mu, sealed for 3 4 hours after ventilation.

2.Apply organic fertilizer and biological fertilizer on the base fertilizer.

People are always accustomed to relying on chemical fertilizers, and ignore the role of organic fertilizers and bacterial fertilizers. In fact, both are indispensable. Bio-fertilization can reduce the occurrence of soil-borne diseases. Mature organic fertilizers can provide more nutrients to crops, but be careful.

3.Land preparation and ridge formation.

Ridge cropping can provide a better growing environment for crops, harmonizing the balance between factors such as water, nutrients, air and heat. Improve soil fertility and provide good conditions for sowing, crop growth and field management.

4.Choose good seedlings when planting.

Choosing healthy seedlings is the biggest prerequisite for planting. Strong seedlings, no pathogens, white and developed roots, and good growth seedlings are the first choice, and seedlings with few root hairs and yellow-brown are best not used.

5.Planting time.

The planting time is generally chosen in the morning or afternoon on a sunny day when the temperature is not very high, so as not to cause the seedlings to wilt due to the high temperature at noon. Dipping roots with rooting fertilizer before planting can improve the survival rate.

2. Post-planting management.

1.Suitable for watering.

Generally speaking, one month after planting, it is important to water three times before watering.

1) Planting water: It needs to be watered thoroughly. Before planting vegetables, the soil in the shed has been turned deep and the air permeability has improved. In addition, seedlings have very few roots, most of which are distributed in a 5 cm tillage layer, so watering with a large amount of water generally does not cause root soaking due to lack of oxygen.

2) Slow seedling water: Generally, it should be watered about 6 to 7 days after planting. Otherwise, it is easy to accumulate water in the field and cause roots. It should be watered at five or six o'clock in the morning.

3) Promote tree water: It is advisable to water about 15 days after slowing down the seedlings. The purpose of this watering is to promote the fruit-setting capacity of the vegetables.

2.Proper ventilation.

The temperature and humidity in the seedbed are high, and the seedlings grow young. If the seedlings are not ventilated for a long time, and then suddenly ventilated, the outside temperature is low, and the air is dry, the seedlings will wither due to the sudden loss of water, and then the leaf cells will be difficult to recover due to the sudden loss of water. In severe cases, the whole leaf is dry, and the mesophyll tissue between the leaf edges or the veins of the network is dry and yellow, and the leaves are like fire.

3.Disease control.

Since some diseases are caused by soil-borne factors, some management measures can be taken before planting to reduce the incidence. For example, measures such as increasing the amount of bacterial fertilizer, deep ploughing of the soil, and high-temperature disinfection. , prevention and control measures should be taken in a timely manner.

1. Be prepared for time, if there is a greenhouse at home, you can't break people in the greenhouse. Especially during the critical period of plant growth, almost all the time is spent working in the greenhouse. 2. Be prepared for illness, the temperature and humidity in the greenhouse are high, and the temperature in the north is low and the humidity is low in winter.

Long-term entry and exit can cause rheumatism, rheumatoid and other diseases. 3. Make income preparation, income preparation here refers to the purchase of off-season vegetables**. Taking the 80-meter greenhouse in western Liaoning as an example, when the average purchase is high, the annual net profit is 5-70,000 yuan.

When the average acquisition is low, the annual net profit is 2-40,000. 4. Be prepared for expenditure, If you build an 80-meter greenhouse in western Liaoning, you need 8-100,000 yuan, which does not include the purchase of fertilizers, pesticides and other expenditures in the later stage.

I want to grow in a greenhouse. First of all, we must understand the temperature and humidity required for plant growth and its growth cycle, and then set up all the environments, and then plant, and when the crops need to be sprayed with pesticides or repellent pests, everything must be followed in steps.

Illness prevention.

Because of long-term work in the greenhouse, the temperature and humidity in the greenhouse are high, and the temperature in the north is low and the humidity is low in winter. Long-term entry and exit can cause rheumatism, rheumatoid and other diseases. This situation is common in rural northeastern areas.

1.Pay attention to the application of CO gas fertilizer; 2.Pay attention to the fertilizing properties of vegetables; 3.

Note that phosphate fertilizer and zinc fertilizer should not be mixed; 4.Pay attention to the jaw effect between potassium and magnesium; 5.Pay attention to the appropriate amount of nitrogen fertilizer; 6.

Note that chlorine-containing fertilizers should not be applied.

Strengthen ventilation and reduce the temperature of the shed. When vegetable farmers plant summer vegetables, in order to avoid high temperature obstacles in the greenhouse, they should pay attention to opening all the upper and lower air outlets of the greenhouse, so that the cold air outside the shed enters the shed, and the hot air in the shed forms a convection flow to accelerate the discharge of hot air, which is conducive to the reduction of the temperature in the shed. Vegetable farmers should be reminded that when the air is released, a windshield film should be set under the air outlet to prevent the cold wind from blowing directly on the fruit surface of the vegetable, resulting in peeling and cracks in the fruit.

It is necessary to pay attention to the temperature, to pay attention to moderation, to do a good job of ventilation, to choose a relatively high quality plastic sheet, and to pay attention to the survival rate of seeds in the planting process.

First of all, Liufang first began to start with the facilities and equipment, rural growers in the construction of greenhouses, do not pursue high-end, so that the cost of greenhouse construction is too high, it may be more beautiful, but it does not play a practical role. Moreover, we choose a very important core from the choice to build a large brother shed address, some growers have built a greenhouse by some natural causes to destroy, such as strong windy weather and heavy rainfall weather, these natural disasters to the greenhouse threat is very high, with the increase in temperature, outside temperature, external insect pests have also entered a high incidence period, so greenhouse vegetable planting during this time must control the density of pests in the shed to avoid insect outbreaks.

<> the main idea of greenhouse planting: according to the environmental needs of crops at various growth stages, the entire production process of crops is completed through planting technology and environmental control means. The following we mainly explain the problems that need to be paid attention to in greenhouse planting from the aspect of environmental regulation:

Greenhouse planting vegetables, to choose high profits, good sales of off-season vegetables for planting, according to the greenhouse space, insulation effect to choose the appropriate vegetable planting, greenhouse temperature regulation to control well, to ensure the normal growth of vegetables!

Chemical fixation often occurs between phosphorus and zinc, and excessive use of phosphate fertilizer will inhibit zinc absorption. The greenhouse temperature is high and the humidity is high, and the effectiveness of phosphorus is 2 3 times higher than that of the open field, so pay attention to reducing the amount of phosphorus appropriately to prevent the effectiveness of inhibiting zinc. If zinc deficiency occurs before planting in a greenhouse, it is necessary to increase the amount of organic fertilizer appropriately, and then turn the soil deep again to remove the dust and weeds of the previous crops.

In addition to increasing the organic matter content in the soil, it can also improve the soil structure and increase the soil permeability.

First of all, it is necessary to pay attention to the problem of watering, because proper water is indispensable for any plant, greenhouse vegetables usually can not accept the rain of nature, so it is necessary to pay special attention, watering should also be based on the observation of vegetables, but also depends on the weather.

No, when planting vegetables, there is still a certain distance, so that the plants can grow better and grow faster.

Yes, because in this way the production can be increased, and there will be no room to spare, and a large area can be managed.

Yes, the greenhouses must be filled with vegetables, so that it looks more aesthetically pleasing, and you can get a good income for yourself.

Of course, there is no need, because the greenhouse full of vegetables will have a very bad environment for celery dismantling, and it will also be very unfavorable to the growth of other vegetables, so it does not need to be planted.

**Insufficient attention and insufficient investment. Although the vegetable industry has undergone more than ten years of development, it is still far from a large vegetable town and a strong vegetable town. Due to the lack of special fund support, the production area roads, bridges, culverts, water, electricity and other infrastructure is poor, bringing a lot of inconvenience to the production of vegetable farmers, in the professional and technical personnel, office facilities, financial security and other aspects of the investment is seriously insufficient, some basic work can not be carried out normally, the existence of these problems, hindering the further development of the town's vegetable industry.

With the introduction of the national rural policy, the local functional departments should actively change the direction of work, change management to service, and actively make suggestions for the development of the local vegetable industry, from the policy, capital and other aspects to be tilted.

Local financial departments have little support for agriculture-related enterprises. Due to the late start of agriculture-related enterprises, the foundation is thin, and the local financial sector has little confidence in financial support, resulting in insufficient funds for enterprises, which is difficult to operate normally, affecting enterprises to become bigger and stronger, and the slow development of local enterprises has affected the process of local vegetable industrialization. Insufficient funds are the "bottleneck" that restricts the development of local agricultural enterprises

If you encounter a large-scale agricultural project, from the county-level unit to the provincial development and reform project, the project materials must have the planning of the park, at this time the county agricultural bureau will take the lead in reviewing the project, and the relevant departments will participate, and the unreasonable planning will definitely not be passed. If your greenhouse is built under the high-voltage line of the State Grid without permission, and the vertical and horizontal distance does not meet the requirements, it will also be ordered to be demolished. Therefore, when building a greenhouse project, it is necessary to communicate with the village cadres first to understand the local greenhouse project policy, so as to establish the corresponding greenhouse project project in combination with its own situation.

Now the vegetables are very expensive, so in the rural development of greenhouse vegetables to increase the income of farmers is a good choice, I grow greenhouse vegetables, first of all, you have to look at the local climate, and then choose the variety, look at the market, choose the water source. Whether the transportation is convenient, there is also a budget in terms of labor.

If you are developing greenhouse vegetable cultivation in the countryside, then you must first consider whether your place is good or not, and then whether you can get the sun, which is very crucial.

The biggest problem is the market problem, that is, the problem of sales channels. Now vegetable greenhouses are everywhere, there are vegetable greenhouse bases, and there are farmers planting first, whether they can be sold, whether they can be sold at a good price is the most difficult problem to solve in front of vegetable greenhouse growers.

Secondly, it is more profitable to grow vegetables, which is also a big problem, to conduct market research, we must not blindly plant a large area.

If you are a rural person, you can use your own land to develop planting, but if not, you need to buy land to develop cultivation. The development of greenhouse vegetable cultivation also requires capital investment, and of course, technology. Generally, it is enough to have funds and technology.

Greenhouse vegetables are basically planted out of season to make money. Especially in winter planting, because the weather is relatively cold, there is little ventilation, and basically the carbon dioxide required for photosynthesis of vegetables and vegetables is consumed by the stove to produce carbon dioxide.

The other is to pay attention to pests, because there are no birds entering, so pests basically have no natural predators, pay attention to insect prevention.

First of all, it is necessary to select a site (a field suitable for greenhouse vegetables), whether the field can grow these vegetables, varieties, water sources, power supply, ventilation, sales channels, pest control, watering, transportation.

First of all, we must consider the elimination of the road, but also consider whether all aspects of technology are supported, and whether the comprehensive calculation of cost and market can make money? These things are done well, and then you can plant a large area and make a lot of money, I wish you success in your business.

One is land, but marketing.

Vegetables are not worried, everyone has to eat vegetables, the key is the variety, there is organic fertilizer, as little as possible pesticides.

Water source, marketing, manpower, technical support!

The most important thing is the sales volume, and other science and technology are relatively not difficult.

Heck, you need to rent a greenhouse first. And then you have to choose the seeds. And fertilization, all aspects have to be considered. After maturity, there will be sales, and all aspects have to be taken into account. Let's take it one step at a time.

Transportation, sales, climate, venues.

Think first about sales, especially for individual development.

There are a lot of considerations for this, first of all, the channel. The end is the kind of vegetable people you want to grow to prevent their house worms and rot status. In the case of greenhouse dishes, it is best to learn this knowledge first.

Special materials may be used, or the building will be carried out according to the size standard of the greenhouse, and bamboo frames may also be used for construction. Pay attention to the cost of the cost, but also pay attention to the money invested, understand the materials used, ensure the temperature, but also pay attention to the working conditions, pay attention to the direction problem, but also pay attention to the size of the area.

Choose the address in advance, choose good lighting conditions, and also choose good ventilation. Then build a steel frame and fix it with steel wire. It is necessary to improve the bearing capacity of the shed, and also choose solid bamboo poles for construction.

Under normal circumstances, it is built by the farmers themselves; Build time, pay attention to quality, pay attention to quantity, improve efficiency, save time.
