The utility model relates to rice seedling raising technical field, concretely is a kind of rice seedling raising water-saving cultivation device, including equipment main frame, water flow channel and seedling raising tray, equipment main frame includes support side plate, and the inside surface of support side plate is arranged with installation clamping groove at equal distance;Water flow channel includes water receiving groove, and water receiving groove is arranged in installation clamping groove bottom;Seedling raising tray includes tray body, and the inside of tray body bottom side is provided with inclined bottom water leakage groove, and the both sides of tray body bottom are provided with water leakage opening and inclined bottom water leakage groove intercommunication, and water leakage opening and water receiving groove upper opening intercommunication.The utility model in the present application, the excess moisture in routine irrigation can directly penetrate through cultivation soil layer and seep into inclined bottom water leakage groove, the bottom of inclined bottom water leakage groove is arc structure, guides moisture to the water leakage opening at both sides, and then is recycled through water receiving groove, so as to be used again, effectively avoid that the excessive soil moisture affects the respiration effect of rice seed, and simultaneously have certain water-saving capacity.

The invention relates to the technical field of tissue culture, and particularly discloses corn tissue culture equipment which comprises a shell and a seedling raising tray, a containing space is formed in the top side of the shell, a plurality of partition plates are fixed to the bottom side of the containing space, the lower half part of the containing space is divided into a plurality of divided spaces by the partition plates, a second pipe body is arranged on each partition plate in a penetrating mode, and the second pipe bodies are connected with the seedling raising tray. The two ends of the second pipe body are bent downwards, the seedling raising plate is located in the containing space and comprises a plurality of cultivation shells which are arranged in the length direction of the shell, the top sides of the cultivation shells are fixedly connected together, a plurality of cultivation grooves are formed in the top side of each cultivation shell, and a plurality of liquid passing holes are formed in the bottom side of each cultivation groove; according to the corn tissue culture equipment, due to the fact that the corn tissue culture equipment is provided with the opening, cleaning is convenient, the plant tissue culture cost is reduced, plant seedlings do not need to be moved in the tissue culture process, and damage to the plant seedlings is reduced.

The invention discloses a method for preparing a biological fertilizer by using a high-purity threonine preparation process, and relates to the technical field of biological fertilizer preparation, and the method has the advantages that a specific adsorption slow-release agent is prepared, the specific adsorption slow-release agent is prepared from nano-scale hydroxyapatite and polyglutamic acid, and the specific adsorption slow-release agent is prepared from the nano-scale hydroxyapatite and the polyglutamic acid; the nano-scale hydroxyapatite strongly adsorbs threonine, nutrient components such as nitrogen, phosphorus and potassium and trace elements such as iron, zinc and copper in the fermentation waste liquid by virtue of high specific surface area and good adsorption performance, and is gradually degraded along with the action of microorganisms in soil and the change of the surrounding environment of a plant root system in the use process of the biological fertilizer; nutrients are continuously provided for different growth stages of plants, so that resource waste is effectively reduced, long-acting and stable supply of nutritional ingredients is realized, and rapid loss of the nutrients is avoided, so that the utilization rate of the fertilizer is remarkably improved, fermentation waste liquid which is possibly abandoned originally is successfully converted into valuable biological fertilizer resources, and environmental pollution is reduced. And continuous power and solid guarantee are provided for healthy growth of plants.
