Example 3

The present embodiment further provides a method for managing additional generation seedlings of crops based on the additional generation hydroponic ecological cabin for crops, which is applied to the additional generation hydroponic ecological cabin for crops, and includes:

acquiring a seedling culture picture, and acquiring seedling culture types and seedling culture growth state characteristics based on a machine vision algorithm;

acquiring a seedling maturity grade according to the seedling type and the seedling growth state characteristics;

generating an irrigation control instruction according to the maturity level:

when the maturity meets a preset level, generating a spraying irrigation control instruction;

when the maturity does not meet the preset level, generating a tidal irrigation control instruction;

and sending an irrigation control instruction to the water culture irrigation device.

It should be noted that the seedling type and the seedling growth state feature are used to obtain the seedling maturity level, and a seedling test is performed to obtain the corresponding relationship between the seedling growth state and the maturity level corresponding to different seedling types. In order to more clearly illustrate the implementation process of the method, the following is specifically illustrated by taking rice as an example:

in this exemplary illustration, the entire seedling stage of rice includes the cultivation process from before sowing of seeds to before transplanting. The maturity levels can be respectively set with different level corresponding relations in time periods of different growth states of seeds before germination, breast breaking and white exposure, cotyledon expansion and two leaves and one heart.

As a preferred embodiment of this embodiment, the setting of maturity levels corresponds to the growth characteristics of the seedling cotyledons at different stages, and the preset maturity level may correspond to the maturity level when the cotyledons are expanded. At the moment, rice cotyledons grow out, and the root system also has a certain function of absorbing irrigation liquid, so that the maturity judging condition for triggering the irrigation mode to switch from spray irrigation to tidal irrigation can be realized.

Specifically, as a specific implementation mode of the irrigation liquid setting, before the cotyledon growth is met, clear water is adopted for the irrigation liquid for spray irrigation, and a shower nozzle is adopted for the shower nozzle for spray irrigation, that is, when the cotyledon for rice seedling raising does not expand to be less than a preset maturity level, the irrigation control unit receives the spray irrigation control instruction and then controls the circulation flow of the clear water in the irrigation circulation unit to the spray pipeline, so that the spray irrigation of the water culture seedling raising device is completed. The cultivation of the rice usually adopts a matrix cultivation mode, the rice is watered without pressure by adopting clear water, the seedling of the rice is cultivated in the matrix environment, the whole environment humidity can reach 95% by continuously spraying, and the seedling growth can be promoted.

After the seedlings grow to form cotyledons, the maturity grade of the cotyledons meets the set condition, and at the moment, after the irrigation control unit receives the tidal irrigation control instruction, the irrigation control unit controls the nutrient solution in the irrigation circulation unit to circularly flow to a tidal irrigation pipeline, so that the tidal irrigation of the water culture seedling device is completed. The irrigation liquid is adjusted into the nutrient solution through tidal irrigation, the root system for seedling cultivation is irrigated from the bottom of the planting tray in the tidal irrigation mode, when the root system is immersed in the nutrient solution, the rice seedling cultivation absorbs nutrients in the nutrient solution through the root system, after the nutrient solution flows out, the root system can be ensured to perform necessary respiration, the root is not rotted, and meanwhile, a certain amount of nutrient solution stored in the matrix can further provide necessary nutrients for the root system. Based on foretell control, the rice seedlings is grown seedlings and is sprayed earlier stage, is favorable to matrix and seed to soak, and guarantees the respiratory of sprouting, and later stage morning and evening tides are cultivated, and humidity is controllable in the region, reduces fungus class and breeds and plant foliage cleaning.

Based on the same theory, the method is also suitable for other seedling raising types, such as crops like solanaceous fruits, barley and the like, the difference is that a preset maturity level needs to be obtained according to a seedling raising test, and the reasonable setting of the maturity level is an important factor for obtaining the expected effect by the method.

As a preferred embodiment of this embodiment, in the embodiment of the present invention, after obtaining the seedling maturity grade according to the seedling type and the seedling growth status characteristics, the method further includes:

generating an environment adjusting instruction according to the maturity and the environment state parameters;

and issuing an environment adjusting instruction to the environment adjusting device.

Taking rice seedling as an example, reasonable control of the environmental conditions of seedling raising is also an important condition for improving the efficiency of seedling raising and cultivation, for example, after the chest-broken white of seedling raising is obtained, germination can be accelerated by controlling the temperature, humidity and illumination environment, and after cotyledon grows out, the growth and development of seedling raising are improved by combining the temperature, humidity conditions, light cultivation and dark cultivation. Meanwhile, gas parameters such as carbon dioxide in the environment and the like which influence the respiration of the rice are detected, and ventilation treatment is carried out in time.

Based on the same theory, the method is also suitable for other seedling raising types, such as crops like solanaceous fruits, barley and the like, the difference is that a preset maturity level needs to be obtained according to a seedling raising test, and the reasonable setting of the maturity level is an important factor for obtaining the expected effect by the method.
