Method for cultivating crops on roof

Abstract

The invention discloses a method for cultivating crops on the roof. The method includes steps of manufacturing a light water-storage cultivating tank, preparing light cultivation medium, mounting a water level adjustment controller at the position of a water inlet pipe of the light water-storage cultivating tank, controlling the water level of the cultivating tank at the required height by the water level adjustment controller, paving the prepared light cultivation medium in the cultivating tank, and planting the crops to be cultivated into the light cultivation medium, wherein the light water-storage cultivating tank comprises a cultivating tank frame inlaid or arranged in a groove bed and a flexible waterproof material layer enclosing the cultivating tank frame, and the light cultivation medium comprises inorganic bearing materials and organic nutrition matrix. The method has the advantages that resources are sufficiently utilized, water and energy are saved, mounting is convenient, cost is low, the roof can be sufficiently utilized, safety of the roof structure is guaranteed and the like.

Description

technical field [0001] The invention belongs to a method for cultivating crops, in particular to a method for cultivating crops on a roof. Background technique [0002] Our country has abundant roof resources. The roof has sufficient temperature and light resources, and the air is dry and circulates quickly. Using the roof to cultivate crops can not only effectively isolate diseases, insect pests and weeds, but also easily obtain high-yield and high-quality agricultural products. It is the preferred place for efficient crop cultivation. However, due to the lack of related technologies for using roofs to cultivate crops, when people use roofs to cultivate crops, they will cause crop death, high cultivation costs, damage to the sanitation environment, and impact on roof safety due to incorrect watering and fertilization and improper management. Taking advantage of failures may even arouse social resentment. [0003] People have been paying attention to the utilization of roof...

Problems solved by technology

The Chinese patent document with the application number CN201320417527 discloses a cultivation device, which consists of a cultivation box with a small top and a large bottom, a water storage tank and a water pump. It has difficulties in making a cultivation pond, inaccurate water supply, The production materials are rough, the cost is high, there is no continuous water source, and the weight is large, which may easily cause safety damage and other defects.

Application number is that the Chinese patent document of CN200410089091 discloses a kind of roof hydroponic lawn greening method and cultivation system, sticks linoleum on the roof, puts turf on its top cover film again, realizes watering with relay constant water supply method; Water resources are wasted, and it is not leak-proof. The fertilization process will also affect the environment and lose fertilizer

The Chinese patent document with the application number CN201310709278 discloses a method for making a substrate for soilless cultivation of vegetables. Its main content is to use coconut shell powder, alcohol biogas residue and straw powder fermentation material and a small amount of auxiliary materials as the substrate formula. The focus is on fermentation treatment. Method; this kind of cultivation medium is difficult to obtain, high in cost, poor in air permeability, and not durable in use

[0004] All there is certain defect in the above prior art, and present roof crop cultivation also has following three prominent technical problems: the first is that there is no targeted watering technology, and present watering mode mainly is artificial watering (comprising regularly water supply with relay) and Drip irrigation, which may lead to roof leakage, and it is difficult to guarantee the water required for plant growth; the second is the lack of anti-leakage and anti-puncture solutions for the roof; the third is that there is no special lightweight and low-cost cultivation substrate and cultivation pool, so that the safety of the roof load is not guaranteed; the fourth is that the resource advantages of the roof itself without disease and insect pest sources and can isolate the source of Cordyceps species are not fully utilized, and the real application value of the roof cannot be fully utilized; due to the existence of these technical problems , so that the function of roof greening is limited, and it is impossible to achieve safe and high-yield roof cultivation crops
