1. Requirements for greenhouse facilities
Vegetable greenhouses generally say that they are planted off-season, and the use of greenhouse equipment to change the growth time of crops allows us to eat fresh vegetables in winter. Now the use of equipment such as vegetable greenhouses can guarantee the supply of fresh vegetables throughout the year. This is also an advancement in our technology. The basic elements of vegetable growth are sunlight, temperature, moisture, fertilizer, etc. Especially in winter, temperature has a great influence on vegetable greenhouse cultivation. The thermal insulation requirements of greenhouses are very high, and the greenhouses also need continuous heating by heating equipment in bad weather. Most vegetable greenhouses are production-type solar greenhouses, which are mainly low-cost environments that can fully meet the needs of vegetable growth.
2. Basic technology of greenhouse planting
Simply speaking, there is no difficulty in planting vegetables. There is no small vegetable garden in the homes of ordinary people. Common vegetables are also grown by everyone, and they grow well. However, greenhouse planting is not unified with ordinary open-air planting. Greenhouse planting is an artificially simulated planting ecological environment, and the temperature and humidity in the greenhouse can be controlled. If the temperature is too high, it will cause crop dehydration or burning seedlings. If the temperature is too low, the powder will be affected, and the fruit setting rate will be low.
3. Analyze the price fluctuations of vegetables in the same period
Everyone now knows that greenhouses are mainly planted off-season, and the vegetable supply in the winter market comes from greenhouses. If you want to grow your own vegetables, you can sell them at a good price in the market, not just the quality of the vegetables. There is no doubt that the variety is good and the price is high. However, the price of vegetables is greatly affected by the market, mainly due to the relationship between supply and demand in the market. Supply exceeds demand, and prices must be low. Supply is less than demand, and the supply price in the market is definitely high. For the growers, the number of varieties to be planted has a very big relationship. This needs to refer to the price range of various vegetables in the same period in the past few years or the suggestions given by relevant departments.
