Azolla germplasm resource preservation device

Abstract

The invention relates to an azolla germplasm resource preservation device, which comprises a base and a cultivation layer frame, wherein preservation boxes for persevering azolla germplasm resources are placed on the cultivation layer frame; a lamp plate component is arranged above the various preservation boxes; water inlet hoses and water outlet hoses all of the various preservation boxes are mutually connected in parallel onto water inlet branch pipes and a return water branch pipe respectively; the water inlet branch pipes and the return water branch pipe are mutually connected in parallel onto a water inlet main pipe and a return water main pipe respectively; a liquid storage tank is arranged in the base, and is connected with the water inlet main pipe and the return water main pipe respectively to form a preservative fluid closed loop; an PLC (Programmable Logic Controller) is arranged in the base, the input end of the PLC is connected with a sensor monitoring unit, the output end of the PLC is connected with the preservative fluid closed loop and an environment control unit to form a closed loop control system, and the PLC is also connected with a GPRS (General Packet Radio Service) communication module. The device has the advantages that independent preservation is realized to prevent the mixing of the azolla resources and the cross contamination of pest and disease damage, a preservation quantity of germplasm resources can be flexibly adjusted, the functions of growth and integrated environment monitoring, adjustment and control are achieved, and the excellent character and hereditary property of the azolla varieties can be preserved permanently.

Description

technical field [0001] The invention relates to the fields of agricultural equipment and agricultural scientific research instruments, in particular to a red pineapple germplasm resource preservation device and a red pineapple active preservation solution. Background technique [0002] The main reasons for the degeneration of varieties are the variation of genetic characteristics of varieties and the decline of vitality caused by unsuitable cultivation and breeding methods. The excellent characters of an excellent variety are formed under certain ecological conditions and cultivation conditions. When the ecological conditions and cultivation methods are not suitable for the requirements of the variety, the excellent traits of the variety will not be fully utilized, resulting in the decline and deterioration of some economic traits of the variety. To permanently preserve the good characters of plant varieties, the ideal method is to grow and reproduce under suitable ecologic...

Problems solved by technology

This method is close to the natural state and is suitable for the preservation of the activity of many weed species. The disadvantage is that it occupies a large area, and the daily management workload such as soil preparation, fertilization and spraying, and harvesting and division is very heavy. It is difficult to survive summer and winter. If it is stored in a greenhouse or greenhouse, it will inevitably further increase investment costs and energy consumption
