How to grow greenhouse vegetables how much can you earn per mu of greenhouse vegetables

Land selection: select relatively flat fields for land renovation, fertilization, weeding and so on. Shed: the span of the shed is between 8-12m, and the length of the greenhouse is between 60-120m. Steel frames or bamboo are used on the posts, covered with no dripping film. Varieties: at present, cucumbers, tomatoes, green peppers and so on are more planted. Temperature: when it is greater than 32 ℃, it should be cooled down, and when it is lower than 0 ℃, it should be heated. Watering: drip irrigation under plastic film. Fertilization: scientific fertilization and prevention of common diseases and insect pests.

With the increasing demand for kinds of food, there are also greenhouse vegetables. Greenhouse vegetables not only enable people to enjoy more vegetables in different seasons. So how should people grow vegetables in the greenhouse? In general, how much can you earn per mu of greenhouse vegetables? Next, the editor will give you a brief explanation about the common sense of vegetables in the greenhouse.

How to grow vegetables in greenhouse

1. First of all, planting greenhouse vegetables, building a greenhouse is necessary, so we need to choose a field opposite the platform to build the greenhouse, and this field is also required to be relatively flat, so it is suitable for balanced fertilization. Before planting, it is necessary to apply Bika fertilizer to renovate the land, fertilize, weed and so on. As the temperature in the greenhouse is different from that of the outside world, appropriate amount of fertilizer should be applied to avoid soil deterioration caused by excessive fertilization. Properly increase the application of phosphorus and potassium fertilizer, reduce the use of nitrogen fertilizer, can also be used to improve the soil, so as to improve the soil quality.

2. In fact, it is a shed structure, which must be suitable for its own site, and its size should be reasonable. It is best to let the span of the shed be between 8 and 12m, the length of the greenhouse should be between 60 and 120m, and three earth walls and three rows of columns should be used. It is best to use steel frames on the pillars. If you really can't, use bamboo. The greenhouse surface is covered with no drip film, so as to increase the temperature in the greenhouse, which is beneficial to the growth of plants in the greenhouse.

3. It is necessary to make an in-depth analysis of the local market for which varieties of vegetables are planted in the greenhouse, and do not plant categories with sufficient local supply. In this way, the vegetables grown cannot afford the price, and may not necessarily have a good market. In addition to the varieties for market research, the second is to consider varieties that are resistant to low temperature, low light requirements, strong resistance, high humidity tolerance, high yield, and short planting time. The greenhouse vegetables with high yield and good quality can meet the market demand and improve economic benefits. at present, cucumber, tomato, green pepper and so on are planted in greenhouse, which can be used as a reference.

4. Regulating the temperature and humidity in the greenhouse is also the focus of vegetable planting technology in the greenhouse, because the greenhouse is airtight, it is easy to produce some harmful substances, which may hinder the growth rate of vegetables. Therefore, it is necessary to correctly control the use of greenhouse gas. It is best to ventilate the greenhouse in the morning to promote the growth of vegetables. When the lunchtime temperature is high, properly open the vents and carry out ventilation operation to avoid harmful gases harming vegetables. If the temperature in the greenhouse is more than 32 ℃, the cooling treatment must be given. At this time, regular ventilation, air vents, spray and so on can be used. When it is lower than 0 ℃, give heating treatment, such as hot air heating, etc. The regulation of temperature and humidity can be well mastered by the accumulation of long-term experience.

5. At present, greenhouse vegetables are basically watered by drip irrigation under plastic film, which is very mature at present, which can not only greatly improve the environment in the greenhouse, but also control the humidity in the normal range and maintain the temperature in the greenhouse, which can effectively reduce the incidence of diseases and greatly increase the yield of vegetables.

6. if you want to improve the yield of vegetables in the greenhouse, then fertilization is necessary, fertilization methods should be scientific, in addition to fertilization, pest control in the process of vegetable growth is also a very important link. Common pests are land tigers, aphids and so on. If you want to choose scientific medicine for disinfestation, it must be the right time and choose the right medicine. In general, choose to contain copper and zinc, this kind of medicine can not only kill bacteria, but also increase the resistance of vegetables and effectively promote the growth of crops; maintain a good ecological environment, reduce humidity, control the growth of diseases and insect pests, reduce the number of drugs; soil-borne bacteria are serious bacteria, if not well controlled in the early stage, growing vegetables will be contaminated by bacteria, so we should pay attention to the prevention of seedling stage The use of physical control, such as deep ploughing, variety selection and so on. When there are different degrees of disease, fertilize according to the disease. Be careful not to overdose when taking medicine, or vegetables will become unhealthy vegetables.

How much can you earn per mu by growing vegetables in greenhouse?

According to the data of our investigation and interview, generally growing vegetables in the greenhouse can earn about 40,000 yuan per mu, and the specific income should be determined according to everyone's local vegetable sales market. The annual income of large and medium-sized arched sheds is generally about 25000 yuan to 30,000 yuan per mu. If large-scale planting, under good market conditions, a profit of 20-300000 a year is not a problem. A reasonable mix of varieties and the launch of your own vegetables at the right time is the most important point to ensure profit.

In the above article, the editor also popularized the science for everyone about how to grow vegetables in the greenhouse. In fact, greenhouse vegetables are also very common in our lives. And almost every household eats different greenhouse vegetables every day.
