Breeding device of sorghum seedling
Technical Field
The invention belongs to the technical field of sorghum breeding, and particularly relates to a sorghum seedling breeding device.
Background
The sorghum seedling breeding refers to the process of cultivating excellent sorghum varieties through means of seed propagation, gene improvement and the like under specific environmental conditions. When the sorghum seedlings are bred by seed propagation, a floating tray or a breeding frame is generally adopted, and compared with the floating tray for breeding, the breeding frame has the advantages of simplicity in operation and low cost, and environmental factors such as illumination, temperature and the like can be better controlled by breeding, so that the growth and development of the sorghum seedlings are facilitated.
At present, a common breeding frame comprises a supporting frame and a plurality of layers of breeding discs detachably connected to the supporting frame, a spray head is arranged between adjacent breeding discs and connected with an external pipeline, water, nutrient solution or medicine is sprayed on sorghum seedlings through the pipeline and the spray head, and meanwhile, a temperature sensor and a humidity sensor are arranged on the supporting frame so as to timely adjust the temperature and the humidity in the breeding discs.
In the process of breeding the sorghum seedling by adopting the breeding frame, as nutrient solution and water are sprayed on the sorghum seedling below through the spray head, the nutrient solution or the water firstly acts on leaves of the sorghum seedling and then is only at roots of the sorghum seedling, if the breeding frame is subjected to humidity supplementation in a semi-dry fog mode, the roots of the sorghum seedling are difficult to supplement with the water, the root system of the sorghum seedling is maldeveloped, the growth of the whole plant is influenced, and the inside of the breeding frame is easy to be excessively moist due to the fact that the leaves of the sorghum seedling are ponded, and diseases are caused due to the fact that rainwater is directly sprayed.

Further, the wall body at the bottom of the breeding tray is internally provided with a converging cavity, the converging cavity is positioned above the water storage cavity, water leakage holes are uniformly distributed at the bottom of the breeding tray and are communicated with the converging cavity, and the converging cavity is also communicated with a drain pipe. Through the setting in chamber that converges, when the moisture in the earth is too much, can enter into the chamber that converges through the hole that leaks and gather, the moisture of gathering can be for the follow-up sorghum seedling provides moisture, also can discharge through the drain pipe.
Further, geotechnical cloth, grass-proof cloth or drip irrigation cloth is arranged at the bottom of the breeding tray. Through setting up geotechnique cloth, preventing grass cloth or drip irrigation cloth, help excessive moisture normally to enter into the chamber that converges to avoid earth to block up apopore or leak the hole.
Further, the water outlet hole comprises a diversion hole and a plurality of overflow holes, the overflow holes are uniformly distributed at the top of the diversion block and are communicated with the top of the diversion hole, and the bottom of the diversion hole is communicated with the diversion pipe. The top of the water outlet hole is provided with a plurality of overflow holes, which is helpful for reducing the impact of the water to the soil.
Further, the support frame is "U" shape, and the top of support frame is equipped with the top cap, and the opening both sides of support frame are equipped with the cloth that keeps out the wind. Through the setting of the windshield, can open or close in order to adjust ventilation volume, humidity and temperature.
Further, gauze is also arranged on two sides of the opening of the supporting frame, and the gauze is positioned between the wind shielding cloth and the breeding tray. Through the arrangement of the gauze, when the wind shielding cloth is opened, the direct irradiation of sunlight to sorghum seedlings can be reduced through the gauze.
Further, a temperature sensor is arranged on the supporting frame. The temperature sensor is convenient for knowing the temperature in the breeding device at any time so as to make adjustment in time.
Further, humidity sensors are arranged on the supporting frame and in the breeding plate. Through humidity sensor's control, cooperation atomizer and apopore are convenient for carry out the adjustment of differentiation to the inside and outside humidity of breeding dish.
In the present application, the control of temperature, humidity and illumination may be implemented by using an environmental controller, which is a conventional technology and will not be described herein.
