Technical Field

The invention belongs to the technical field of floating seedling of flue-cured tobacco, and particularly relates to a flue-cured tobacco floating seedling airing device based on the Internet of things.

Background

The floating seedling of the flue-cured tobacco is the main mode of the current seedling of the flue-cured tobacco, and makes great contribution to the cultivation and production of high-quality flue-cured tobacco.

In general, tobacco seedlings grown in floating mode need to pass through the following four growing periods:

(1) and (5) seedling emergence stage. Generally means the growth period from the sowing of tobacco to the emergence of seedlings;

(2) and (4) a cross period. Generally, the first and second true leaves appear in succession shortly after the emergence of the tobacco seedling, and the cross stage is called when the leaves are similar in size and cross-shaped. At the moment, the main roots of the seedlings are very shallow in soil, slow in growth, weak in drought resistance and disease resistance;

(3) and (5) rooting period. Generally refers to the growth period from the birth of the 3 rd true leaf to the birth of the 7 th true leaf. In this period, the growth center is transferred to the underground part, i.e. the root system is actively growing. The central task of cultivation management is to promote the seedlings to form developed root systems;

(4) and (5) seedling stage. Generally means a period from the birth of the 7 th true leaf to the arrival of the tobacco seedling which is suitable for transplanting standard. At this time, the seedling growth center begins to transfer to the overground part, i.e. the overground part grows faster than the root system.

Airing trays are important technical links of floating seedling of the flue-cured tobaccos. The airing disc is a technical operation of separating a floating disc for floating seedling from the water surface of the seedling pool. The airing plate is mainly used for artificially applying appropriate stress such as water, nutrients, illumination and the like to the tobacco seedlings before transplantation so as to increase the keratinization degree of the tobacco seedlings, so that the tobacco seedlings gradually build tolerance and resistance to stress factors such as water, nutrients and the like, and adapt to the field environment after transplantation as soon as possible, thereby improving the survival rate and seedling returning speed of the tobacco seedlings after transplantation.

Generally, the modes commonly adopted by the tray airing include the modes of draining water in the seedling raising pool, lifting a floating tray and the like, and the modes generally have the defects of time and labor consumption, low efficiency, resource waste, high cost and the like, and are not beneficial to improving the seedling raising quality.

Disclosure of Invention

The invention aims to overcome the defects of the prior art, and provides the flue-cured tobacco floating seedling airing tray device based on the Internet of things, which can efficiently and quickly realize airing trays on one hand, and can also control the airing tray degree by observing the wilting degree of tobacco seedlings through the Internet of things and a field camera on the other hand, thereby achieving the purposes of scientific, efficient and remote control and further improving the floating seedling quality.

The technical scheme of the invention is as follows:

the utility model provides a flue-cured tobacco floats grows seedlings and dries in air dish device based on thing networking comprises nursery pond, two-way self priming pump, automatically controlled cabinet, camera, wireless communication module, remote monitoring computer and mobile terminal, the nursery pond includes the multiunit, and every group comprises two nursery ponds, two-way self priming pump is located between two same ends in nursery ponds for realize wherein with the nutrient solution in a nursery pond of group take out toward another nursery pond. A plurality of floating plate groups are arranged in each seedling raising pool, each floating plate group comprises a plurality of floating plates, and support legs are arranged on the back of each floating plate. The camera is located beside the seedling raising pond and used for observing the growth state of the tobacco seedlings. The electric control cabinet is located on the site of the tobacco seedling greenhouse and used for controlling the starting, stopping and extracting directions of the bidirectional self-sucking pump. The wireless communication module is used for realizing the link of the electric control cabinet, the camera and the remote monitoring computer, and the mobile terminal is linked with the remote monitoring computer in a wireless communication mode to realize the image monitoring of the field camera and the remote control function of the electric control cabinet.

Preferably, the bottom of the pond of growing seedlings to the one end slope that sets up two-way self priming pump and be less than relative other end 10 ~ 20mm, be convenient for take out the pond of growing seedlings completely futilely.

Preferably, the floating disc is rectangular, and four corners of the back surface of the floating disc are respectively provided with a support leg.

Preferably, the length and width of the floating disc is 527 × 343 × 58mm, and the length and width of the support legs is 20 × 40 mm.

Preferably, the electric control cabinet controls the bidirectional self-priming pump to completely pump the nutrient solution in the first seedling raising pool of the same group, and at the moment, the floating plate in the first seedling raising pool with the pumped nutrient solution falls on the bottom of the pool, and the floating plate is kept for airing until the technical requirement of airing is met; then pumping the nutrient solution in the second seedling raising pool into the first seedling raising pool, airing the second seedling raising pool, and keeping the floating plate airing the plate until the technical requirement of airing the plate is met; then the nutrient solution in the first nursery pond is pumped into the second nursery pond, and the first nursery pond is aired and coiled, and the operation is repeated.

Preferably, the tray airing requires that the growth state change of the tobacco seedlings is observed through the camera until the tray airing is reached, which is reflected in a wilting state in the noon of the day and a normal growth state in the morning and at night.

Further, the tray is dried 15 days before the transplanting in the seedling stage, the conditions of the current evening are further observed when the tobacco seedlings are normal in the morning of the current day and the first to the sixth true leaves are wilted in the noon of the current day, and the tray drying is stopped when the first to the fifth true leaves are basically recovered to the growth state in the noon of the current day but are still in the wilted state slightly in the morning of the current day.

Preferably, the plate airing is carried out for 2-3 times, and the plate airing time is 2-3 days each time. The picture observation shows that the bamboo shoot is wilting in the noon and can recover normal growth in the morning and evening, and the picture observation is usually carried out on the 2 nd day or the 3 rd day of airing.

Preferably, a movable one-way self-sucking pump is further arranged and used for completely sucking water when the water pumping effect is poor.

According to the invention, each group of seedling raising pond is composed of two seedling raising ponds, and the nutrient solution in one seedling raising pond in the same group is pumped to the other seedling raising pond by using a bidirectional self-sucking pump and is pumped back and forth to realize alternate airing. In order to reduce the resistance of extracting the nutrient solution, the back of the floating tray is provided with support legs, so that the nutrient solution at the bottom of the pool can flow conveniently. The invention realizes remote monitoring and control based on the Internet of things, can effectively control the tray airing by remotely observing the wilting degree of the tobacco seedlings, and greatly improves the efficiency. By using the air-curing tray device, in the same seedling raising greenhouse, tobacco seedlings of the same flue-cured tobacco variety and the same seedling age and adopting the same nutrient solution are compared with tobacco seedlings which are not subjected to air-curing, and the tobacco seedlings are developed in root system (long main roots and large in fibrous root number), large in stem circumference and good in leaf growth state, so that the technical scheme of the invention has exact beneficial effects.
