Question 2: What soil should be used to grow vegetables on the roof? You can use the soil of vegetable fields to grow vegetables on the roof. Growing vegetables on the roof is not much different from growing vegetables on the ground, but you should pay attention to drainage to prevent soil erosion. (For reference only)

Question 4: I want to grow vegetables on the roof. What kind of formula soil do I need? What is the best way to grow them in plastic vegetable boxes or wooden boxes? Plant it directly on the balcony for fear of damaging the insulation of the house. Fertilizers in the soil can be bought from chicken manure and compound fertilizer online. The ratio can be soil: fertilizer = 8:2. When sowing, you can open a ditch, sprinkle fertilizer, cover the fertilizer with soil, and then sprinkle seeds on the soil. Cover the seeds with about 2 cm of soil. Water it. Just do it.
Question 5: What do you need to prepare for growing vegetables on the roof? Under normal circumstances, the floor and balcony can bear 300 kilograms per square meter, and the weight of soil and water with a thickness of more than 20 centimeters per square meter will not exceed 150 kilograms; After the floor is waterproof, you can grow vegetables. When laying the isolation layer, pay attention to the use of non-porous plastic film to lay the foundation, and the surrounding area should be 3cm higher than the ground, forming a 3cm water retaining layer at the boundary. According to the planned crop varieties and roof parts, the thickness of filling soil is determined, such as spinach, Chinese cabbage, sweet potato dish, Guanyin dish and other leafy vegetables with a covering thickness of 5 cm; The soil thickness of beans and melons is 8- 10 cm.
Before planting vegetables, the soil should be exposed to the hot sun and disinfected by potassium permanganate to remove diseases and weeds. Daily management can't use manure, only biological fertilizer, mineral fertilizer and commercial organic fertilizer. If there are bugs in vegetables, try to prevent them artificially, or use washing powder or a little biological pesticide.
Therefore, it is not difficult to see that the key to growing vegetables on the roof is leakage prevention, moisture preservation and pests and diseases. The first two of these three items are more troublesome. It is necessary not only to prevent water leakage downstairs, but also to consider that the moisture caused by strong sunlight and thick soil on the roof is not easy to moisturize. Anyone who has planted vegetables knows that the moisture in the soil is very important for the survival and growth of crops, so it is the most difficult to grow vegetables on the roof.
In order to solve this problem, I suggest you take an examination of the automatic humidity control planting box invented by Dongguan Lujia Green. This kind of vegetable box solves the problem of moisturizing, does not need manual watering, and automatically adjusts the humidity, even if the owner 1 month is not at home. The detailed introduction and real-life pictures of roof planting are on their website.
This is their online engineering case:
Question 6: What should I pay attention to when growing vegetables on the roof? The upper and lower passages should be arranged reasonably to prevent safety accidents. In addition, the waterproof problem of the roof should be handled well, and the soil layer should not be too thin, about 4 or 50 cm, and nothing else is important.
Question 7: How high is the best place to grow vegetables on the roof? Cut the pond with red bricks, the soil is 20-30 cm. I will send you a piece of my vegetable garden for your reference.
Question 8: How thick soil does it take to grow vegetables on terraced fields? 20cm is enough for growing vegetables. Of course, the deeper the soil layer, the better, because there is more water retention. If you feel that the amount of earth moving is too large, you can do single-layer water storage planting. The problem of soil thickness does have an impact on the cultivation of fruits and vegetables, but this problem can be solved by management, that is, using water and fertilizer to supplement it. Generally speaking, the thickness of soil for planting vegetables on the roof is 10 cm to 30 cm.
There are several problems that need to be solved when growing vegetables on the roof: First, it is hot in summer, with severe light and freezing in winter, or avoiding or building sheds. Second, there should be an adequate supply of water. The third is the substrate, and it is best to use organic fertilizer with sufficient fertility and long fertilizer efficiency. The thickness of soil is determined according to the plant root length of species. If you master the nutritional needs of plants in different periods, a small amount of soil or even no soil is enough. If the cost is low, the labor intensity is low and the management is extensive, it is better to choose richer soil.
Question 9: Can I grow vegetables directly on the roof? What roof? Cast-in-place floor? Waterproof will be better; The roof of your own house? Water leakage is less troublesome; In fact, no matter what kind, it is recommended to make a waterproof layer first, and then lay a protective layer to avoid the trouble of water leakage treatment in the future.
