Problems solved by technology

[0003] The plants cultivated by hydroponics are clean and easy to sell, but there are also certain problems in hydroponics. One is that in the process of cultivation, frequent supply of nutrient solution is required, and the other is that in the process of cultivation, the roots of plants Immersed in the nutrient solution, the phenomenon of plant hypoxia will appear, and in severe cases, the root system will die

Embodiment 1

[0027] like Figure 1-4 As shown, this embodiment discloses a soilless cultivation nutrient solution circulation irrigation system, including a fertilizer distribution mechanism and a cultivation mechanism 2, the fertilizer distribution mechanism includes a liquid storage tank 101, a liquid supply main pipe 102, a water pump 103 and a fertilizer distribution bucket 104, Liquid storage tanks 101 are evenly arranged side by side, and the top of the rear side plates of the liquid storage tanks 101 are all fixedly connected with brackets 105, and the liquid supply main pipes 102 are fixedly connected through the brackets 105. The liquid supply secondary pipe 106 corresponding to the liquid pool 101, the water inlet of the water pump 103 is connected to the bottom of the fertilizer distribution bucket 104 through the pipeline, the water outlet of the water pump 103 is connected to the liquid supply main pipe 102 through the pipeline, and the water pump 103 is powered by an external ...

Embodiment 2

[0033] like Figure 5 Shown, the present invention also discloses a kind of soilless culture nutrient solution circulation irrigation method, and this method comprises the following contents:

[0034] S1: Dig trenches side by side on the ground in the greenhouse for soilless cultivation, evenly dig holes on both sides of the trench, and pour the liquid storage tank 101 with waterproof concrete in the trench, during the pouring process of the liquid storage tank 101 , integrally pouring the second installation cover 206 on its left and right side plates, pouring the indwelling bucket 201 with waterproof concrete in the hole, during the process of leaving the bucket 201 pouring, the first installation cover 205 and the indwelling bucket 201 are integrally poured.

[0035] S2: Install the two ends of the communication pipe 202 in the paired first installation sleeve 205 and the second installation sleeve 206, and connect the first installation sleeve 205, the second installation ...

Abstract

The invention discloses a soilless-culture nutrient solution circulating irrigation system and irrigation method. The system includes a fertilizer allocation mechanism and cultivation mechanisms. Thefertilizer allocation mechanism includes liquid storage tanks, a liquid supply main pipe, a water pump and a fertilizer allocation barrel. The left and right sides of each liquid storage tank are eachprovided with one set of cultivation mechanisms, and each set of cultivation mechanisms includes a plurality of cultivation mechanisms uniformly arranged in the length directions of the liquid storage tanks. The problem is solved that nutrient solutions need to be added frequently, and meanwhile the situations are avoided that the root systems of plants are directly soaked in the nutrient solutions and the root systems of the plants rot due to oxygen deficit.

Description

technical field [0001] The invention relates to the technical field of soilless cultivation, in particular to a soilless cultivation nutrient solution circulation irrigation system and an irrigation method. Background technique [0002] Soilless cultivation refers to a cultivation method in which water, peat or forest leaf mulch, vermiculite and other media are used as the substrate for the root system of the plant to fix the plant, and the root system of the plant can directly contact the nutrient solution. The composition of nutrient solution in soilless culture is easy to control and can be adjusted at any time. In places where the light and temperature are suitable but there is no soil, such as deserts, beaches, and deserted islands, as long as there is a certain amount of fresh water supply, it can be carried out. Soilless cultivation is divided into hydroponics, mist (air) cultivation and substrate cultivation according to different cultivation media. Hydroponics ref...
