Embodiment 1

[0033] Such as figure 1 Shown is a closed circulation rock wool cultivation system of the present invention, including a cultivation subsystem, an irrigation subsystem, a nutrient solution recovery and disinfection subsystem, a monitoring unit and a control unit.

[0034] The cultivation subsystem includes a closed cultivation tank 1 and supports for cultivating plants. A rock wool matrix is ​​arranged in the cultivation tank 1, and the cultivation tank is provided with a loam cake, and the loam cake is provided with a planting hole for the plants to pass through. Ventilation pipes are integrated on the cultivation tank for microenvironmental adjustment in the rhizosphere and between plants. The lower end of the support is provided with a crossbeam, and the cultivation tank 1 is fixedly arranged on the crossbeam. The support above the cultivation tank 1 is provided with a hanging vine track. Hanging rings are arranged on the vine track, and the hanging vine ropes pass throu...

Embodiment 2

[0046] Such as figure 2 Shown, be a kind of rock wool cultivation control method of the present invention, comprise the following steps:

[0047] S1, input the initial leaf number when the plant is planted, and judge the initial physiological development time of the plant according to the initial leaf number;

[0048] Enter the initial number of leaves the plant had when it was established in the gutter. According to the initial leaf number, the initial physiological development time of the plant can be automatically judged. The initial physiological development time is the physiological development time before plant colonization.

[0049] S2. Obtain the daily temperature value, calculate the daily physiological development time of the plant according to the daily temperature value, and accumulate it to obtain the physiological development time of the plant after planting;

[0050] The monitoring unit collects and records daily temperature values. According to the three b...

Embodiment 3

[0064] This embodiment is basically the same as Embodiment 2. For the sake of brevity, in the description process of this embodiment, the same technical features as Embodiment 2 will not be described, and only the differences between this embodiment and Embodiment 2 will be described:

[0065] Step S2 also includes obtaining the daily solar radiation value, calculating the radiation product according to the daily temperature value and solar radiation value, and accumulating; step S3 also includes establishing a growth and development model, and according to the accumulated radiation product, through the The above growth and development model is used to obtain the growth and development information of the plant; step S4 also includes adjusting the composition and concentration of the nutrient solution according to the growth and development information of the plant.

[0066] Specifically, the monitoring unit collects and records the daily temperature value and solar radiation va...

Abstract

The invention provides a closed recycling rock wool cultivation system. The rock wool cultivation system comprises cultivation grooves, a nutrient solution pond, drip irrigation components, a nutrient solution recycling disinfection subsystem, a monitor unit and a control unit; the nutrient solution pond and the irrigation components are used for the transport of nutrient solution to plants, the nutrient solution recycling disinfection subsystem is used for the disinfection and the recycling of the nutrient solution in the cultivation grooves, the monitor unit is used for the monitoring of environmental parameters and the irrigation and recycling amount of the nutrient solution, the opening and closing of the drip irrigation components are controlled by the control unit based on the monitoring information. The invention also provides a rock wool cultivation control method. The cultivation control method comprises the steps that the initial physio-genesis time is determined based on the initial leaf number at the colonization of the plants; the physio-genesis time after the planting of the plants is calculated based on the temperature values in each day; the total physio-genesis time of the plants is calculated and the fertility period is estimated according to the initial physio-genesis time of the plants and the physio-genesis time after the colonization; nutrient solution is prepared according to the fertility period of the plants; the plants are estimated whether the irrigation should be conducted according to the basis that whether or not the rea-time light accumulation amount is greater than the arranged light accumulation amount.

Description

technical field [0001] The invention relates to the technical field of agricultural soilless cultivation, in particular to a closed circulation rock wool cultivation system and a control method. Background technique [0002] Soilless cultivation is cultivated by using nutrient solution to supply plant nutrients, including hydroponics, substrate cultivation, etc. Rock wool was first used as a substrate by the Danes around 1970. Due to its unique advantages, it has become the most extensive substrate for research and cultivation of plants after soil. [0003] The key to the success of rock wool cultivation is to manage the nutrient solution and irrigation time well to meet the needs of the optimal nutritional state. The core technologies in rock wool planting are Water Management and Nutrition Management. This is a set of precise management technologies, through which the growth of the root system can be effectively controlled, and the balance between vegetative growth and re...
