Problems solved by technology

[0005] The existing method of producing agricultural products on the roof cannot guarantee that the crops cultivated on the roof will not be damaged by diseases, insects and weeds, and there are problems such as poor roof waterproofing, poor cultivation and irrigation, and high production costs.
The biggest disadvantage is that it does not make full use of the advantages of the height of the roof from the ground, which can effectively isolate the source of crop diseases, pests and weeds from the ground

Embodiment 1

[0050] Embodiment 1: A kind of method utilizing wood cultivation pond to carry out the roof production non-phytotoxic crops

[0051] The method of the present embodiment comprises the following steps:

[0052] 1. Choose a suitable roof: choose a roof with a height of more than 20 meters, or a floor with 6 or more floors. There is plenty of sunlight (direct sunlight throughout the day is best), and the surrounding air passages are spacious. It must also be ensured that there are no other roofs or buildings within 500 meters around the roof that are close to other heights that have been planted with crops and become a source of pest weed seed transmission, or that the altitude is close to the hillside where plants grow, so as to ensure that the source of pest weeds around is not Will enter the roof due to air movement. There is a safety fence or parapet around the roof, and there is a pressurized water source that can be connected to the roof. The roof slope is less than 5 de...

Embodiment 2

[0073] Embodiment 2: A kind of method that utilizes light-weight brick slab cultivation pool to carry out the method for producing non-phytotoxicity crops on the roof

[0074] 1. Choose a roof with a height of more than 30 meters, or a roof with a floor of 10 floors or above, with sufficient sunlight (direct sunlight throughout the day is best), and a roof with a parapet.

[0075]2-6 are the same as in Example 1.

[0076] 7. Make a cultivation pond with a light middle and lower part that can store and transfer water.

[0077] 1) Make lightweight brick panels. Make a brick or board mold according to the required brick or board specifications, mix perlite, pottery sand, and cement at a volume ratio of 2:2:1 or an appropriate volume ratio and add water to make mortar, and pour the mortar into the mold. After compaction, wait for solidification, and apply water in time after solidification to ensure the solidification strength. After the cement solidification degree reaches the...

Embodiment 3

[0085] Embodiment 3: A kind of method that utilizes simple cultivation pond to carry out the method for producing non-phytotoxicity crops on the roof

[0086] 1. Choose a roof with an altitude of more than 60 meters, or a roof with a floor above 20 floors, sufficient sunlight (direct sunlight throughout the day is best), and a parapet.

[0087] 2 to 5 are the same as in Example 1.

[0088] 6. Stainless steel is used to make the bottom of the cultivation pond. Make the stainless steel water storage basin at the bottom of the cultivation pool by 1.22 meters wide, 5.44 meters long and 0.15 meters high.

[0089] 7. Make a cultivation pond with a light middle and lower part that can store and transfer water.

[0090] 1) Choose to process foam plastic boxes. According to the foam plastic boxes whose length, width and height are 60, 45, and 32 centimeters respectively, and the thickness of the foam plastic layer is 3 cm, select 24 foam plastic boxes, and drill a hole with a diamet...

Abstract

The invention discloses a method for producing chemical-hazard-free agricultural products on roofs. The method includes selecting a roof; performing waterproofing treatment on the roof; arranging insect-preventing and bird-repelling net on the roof; building a water storage tank as a water-storage bottom of a culture pond, and then building walls of the culture pond; spreading a water-permeable material on the water-storage bottom as a water transfer layer, covering the water transfer layer with a water-permeable partition plate to separate culture media from the water transfer layer; arranging automatic water supply; preparing the culture media and filling the culture pond with the culture media; sowing seeds, growing seedling, culturing until harvesting in the roof in the whole process.Due to the fact that the roof is high above the ground, intrusion of sources of diseases, insect pests and weeds can be prevented effectively; with enough sun and good air resource, temperature-difference effect better than that of culture on ground and enough water and fertilizer supply, agricultural products produced on the roof can meet requirements on high yield and high quality, the roof is prevented from being a propagating source of diseases, insect pests and weeds, and feasibility of producing safety agricultural products on surrounding roofs is also guaranteed.

Description

technical field [0001] The invention belongs to the technical field of agricultural production, and in particular relates to a method for producing non-toxic agricultural products by using roofs. Background technique [0002] With the economic development of our country, the speed of urbanization is accelerating, rural people are moving into the city, and the demand for houses is increasing. Many houses have emerged in many cities. Each house will have a roof. Looking from a high place, the whole city A concrete forest where the roofs are black spots in the city. Due to the level of science and technology, most of the roofs of our cities are empty, and a small part of them is used to place solar water heaters, and some of them are used as heat insulation layers. In the city where every inch of land is expensive, leaving a good roof vacant always has a feeling of pity in people's minds. Many people want to use the roof, and the biggest wish is to build a roof garden, which ...
