In recent years, as people's standard of living has been rising, many people have become half-eat-eaters, and many vegetables and fruits, with a little taste, know what quality they are, and even know how to produce. Or is the fruit and vegetables grown in the shed not yet tasted well, or even tasted like chewing wax, according to the northeast words of the home of the young writer: “wished by the water.” so why not eat the fruit and vegetables of the shed? Mr. Wang, the neighbor of xiao jing, has more than 10 years of experience in growing a shed, and he points out three reasons。
Light co-operation is bad
It is well known that a membrane is covered outside the shed so that the temperature in the shed can reach normal summer temperatures, so that the desire to eat counter-season fruits can be realized, but it is also because such a membrane does not allow the sun to be fully irradiated on a plant, does not have access to the vegetables for light-cooperative use, tastes are dim and fruits are not sweet, because plants need to use sunlight as a medium, water and carbon dioxide as raw materials, for light-cooperative use, and then excrete oxygen after glucose, which explains why the strawberries bought in the summer are so sweet, and in winter, strawberries are not only sweet, but are acidic, mostly due to the growing of large sheds。
Fertilizer ripening
Many of the nuts are slower to grow because of the lack of light and ventilation in the sheds, but in order to accelerate the growth of the fruit and vegetables, some farmers have opted for fertilizers, which are more guaranteed to be sold on time, generally divided into nitrogen, phosphorus, potassium and compound fertilizers, the main components of which are proteins, most commonly urea nitrogen fertilizer, which is not harmful to the soil, can be used to increase production, and has the effect of attaining a small early maturity, which, if used within national standards, is not problematic, to some extent affects the taste of the fruit。
Long and short
In the case of cucumbers, for example, cucumbers grow for approximately 50-55 days outside the house, but they mature within the shed for about 10 days, which is the result of warm indoors and the catalytic effects of chemical fertilizers. The fast-born cucumbers are not only of poor taste, they are expensive。
However, it is also beneficial to grow vegetables in the sheds, first of all by eating anti-season food, which is known to all to be controlled and kept warm. Because the sheds are sealed, relatively less pests and pests, naturally less pesticide use, and if they cover the rain, they can be effectively avoided for plants that are most afraid of the weather。
