Greenhouse Vegetable Planting Methods and Profit Analysis per Mu
AbstractSite selection: choose relatively flat field, renew the land, fertilize, weed, etc. Build a greenhouse: the span of the greenhouse type is between 8-12m, the length of the greenhouse is between 60-120m, use steel frames or bamboo on the upright posts, and cover with drip-free film. Varieties: currently the most commonly planted are cucumber, tomato, green pepper, etc. Temperature: when above 32°C, cool it down; when below 0°C, heat it up. Watering: use drip irrigation under film. Fertilization: scientific fertilization and prevention of common diseases and insect pests.
As people's demand for types of food increases more and more, greenhouse vegetables have now appeared. Greenhouse vegetables not only allow people to enjoy more vegetables in different seasons. So how should people plant greenhouse vegetables? Generally, how much money can be earned per mu by planting greenhouse vegetables? Next, the editor will briefly explain to everyone some basic knowledge about greenhouse vegetables.
How to plant greenhouse vegetables
1. First, to plant greenhouse vegetables, building a greenhouse is essential, so a relatively flat field needs to be selected for building the greenhouse, and this field is also required to be relatively level, so that it is suitable for balanced fertilization. Before planting, apply Bika bacterial fertilizer to renew the land, fertilize, weed, etc. Because the temperature inside the greenhouse differs somewhat from the outside, fertilization should be moderate to avoid excessive fertilization causing soil deterioration. Appropriately increase the application of phosphorus and potassium fertilizers and reduce the use of nitrogen fertilizer. Bika bacterial fertilizer can also be applied to improve the soil, thereby improving soil quality.
2. Next is the greenhouse structure, which must suit your own site, and the dimensions must be reasonable. It is best to make the span of the greenhouse type between 8 ~ 12m, the length of the greenhouse between 60 ~ 120m, with three-sided earth walls and three rows of upright posts. On the upright posts, it is best to use steel frames; if that is really not possible, use bamboo. Use drip-free film on the greenhouse surface, thereby increasing the temperature inside the greenhouse, which is beneficial to plant growth inside the greenhouse.
3. As for which varieties of greenhouse vegetables to plant, you need to make an in-depth analysis of the local market. Do not plant categories that are already in very sufficient supply locally, because then the vegetables grown cannot fetch a good price, and there may not necessarily be a good sales channel. In addition to investigating varieties for the market, next consider varieties that are tolerant to low temperatures, have low light requirements, strong resistance, tolerance to high humidity, high yield, and short planting time. Only if the greenhouse vegetables grown have high yield and good quality can they meet market demand and improve economic benefits. At present, the varieties more commonly planted in greenhouses are cucumber, tomato, green pepper, etc., which can serve as a reference.
4. Regulating the temperature and humidity inside the greenhouse is also a key point in greenhouse vegetable planting techniques. Because the greenhouse is closed, some harmful substances are easily produced, and these harmful substances may hinder the growth rate of vegetables. Therefore, it is necessary to correctly control the greenhouse air and use the greenhouse air. It is best to ventilate the greenhouse in the morning to promote vegetable growth. When the temperature is relatively high at noon, appropriately open the vents and carry out ventilation operations to avoid harmful gases harming the vegetables. If the temperature inside the greenhouse is greater than 32°C, cooling treatment must be given; at this time, regular greenhouse opening for ventilation, vent holes, spraying, etc. can be used. When it is lower than 0°C, give heating treatment, such as hot air heating, etc. The regulation of temperature and humidity depends on long-term accumulated experience to be mastered very well.
5. Greenhouse vegetables at present basically use drip irrigation under film for watering. This method is already very mature at present. It can not only greatly improve the environment inside the greenhouse, but also control humidity within a normal range, maintain the temperature inside the greenhouse, effectively reduce the incidence of diseases, and greatly increase vegetable yield.
6. If you want to increase the yield of greenhouse vegetables, then fertilization is essential, and the fertilization method must be scientific. In addition to fertilization, disease and pest prevention during vegetable growth is also a very important part. Common pests include cutworms, aphids, etc. For pest control, choose scientific pesticide application; it must be at the correct time and with good medicine selected. Under normal circumstances, choose agents containing copper and zinc. This type of medicine can not only provide super-strong sterilization, but also increase the resistance of vegetables and effectively promote crop growth; maintain a good ecological environment and reduce humidity, which can control the growth of diseases and pests and reduce the number of pesticide applications; soil-borne bacteria are serious pathogens. If they are not well controlled in the early stage, the vegetables being grown will be contaminated by the pathogens, so prevention at the seedling stage must be taken seriously; adopt physical control, such as deep plowing and deep turning, variety selection, etc. When diseases of varying degrees appear, apply fertilizer according to the symptoms. When applying pesticide, be sure not to overdose, otherwise the vegetables will become unhealthy vegetables.
How much money can be earned per mu by planting greenhouse vegetables
According to the data from our survey and interviews, generally planting greenhouse vegetables can earn about 40,000 yuan per mu. The specific income depends on the local vegetable sales market conditions. The annual income per mu for large and medium arch sheds is generally about 25,000 to 30,000 yuan. If planted on a large scale, under good market conditions, a profit of 200,000-300,000 yuan a year is not a problem. Reasonably matching planting varieties and putting your own vegetables on the market at the appropriate time is the most critical point for ensuring profit.
In the above article, the editor also explained to everyone the methods for how greenhouse vegetables should be planted. In fact, greenhouse vegetables are also very common in our lives now. Moreover, almost every household eats different greenhouse vegetables every day.
