5 results about "Mass propagation" patented technology

The present application relates to a kind of methods for mass propagation of tea corner miridae in laboratory, comprising the following technical steps: collecting tea garden tea corner miridae adult, cultivating fall kui seedling, putting seedling and leading insect, tea corner miridae habitat and feeding, mating and oviposition and nymph hatching and feeding.The present application uses fall kui seedling as the main body of feeding raw material, and the leaf of raw material is relatively thick, strong in harm resistance, not easy to dry, which helps to improve the hatching rate of tea corner miridae eggs, reduce the frequency of raw material supply and replacement, at the same time, the present application saves time and effort, can be realized in laboratory low cost and sustainability fast, efficient, mass propagation of tea corner miridae test insect source.

A system and method for growing microalgae capable of mixotrophic metabolism, preferably Chlorella sp. Microalgae grown in the system using the method are able to survive and grow in dark refrigeration, which allows the algae to be stored and transported for application as a live culture. In addition, the microalgae can be grown in sufficient quantities to be sold commercially for application to crops as a biostimulant.

The utility model relates to the technical field of pomacea canaliculata physical prevention and control, aims to solve the problems that in the prior art, the egg killing efficiency is low, the environment is prone to being polluted, the prevention and control effect is slow, mass propagation of pomacea canaliculata cannot be prevented, and the local ecological environment cannot be rapidly recovered, and provides a pomacea canaliculata egg killer which comprises a telescopic rod. The top end of the telescopic rod is detachably connected with a rolling device used for grinding ampullaria gigas eggs, the rolling device is provided with a connecting frame, the end, close to the telescopic rod, of the connecting frame is detachably and fixedly connected to one end of the telescopic rod, the end, away from the telescopic rod, of the connecting frame is provided with a rotatable roller, and the outer wall of the roller is provided with a plurality of spikes. And the plurality of spikes are uniformly distributed on the outer wall of the roller. The pomacea canaliculata egg killing device has the advantages of being high in egg killing efficiency, free of environment pollution, fast in prevention and treatment effect and capable of rapidly preventing the pomacea canaliculata from mass propagation and rapidly recovering the local ecological environment.

The utility model discloses a spartina alterniflora harvester which comprises a main machine body in which an engine is arranged, and further comprises a cab arranged on the main machine body; the conveying assembly is obliquely arranged on the main machine body, is close to the cab and comprises a header conveying belt and a first supporting frame, one end of the first supporting frame is connected with the conveying assembly, the other end of the first supporting frame is connected with the main machine body, and the feeding end of the header conveying belt is lower than the discharging end of the header conveying belt; the cutting assembly is arranged at the feeding end of the conveying assembly, is used for cutting spartina alterniflora and comprises a cutting knife and a collecting roller, the cutting knife is connected with the collecting roller, and the collecting roller is connected with the header conveying belt. By arranging the collecting box, grass seeds of the spartina alterniflora can be prevented from leaking to the mud flat and being transported along the way, mass propagation of the spartina alterniflora can be avoided, the header conveying belt and the conveying belt in the collecting box are made of stainless steel grid materials, the spartina alterniflora cut by the cutting assembly is drained through the stainless steel grid conveying belt, and the weight of the spartina alterniflora is reduced; and the resource consumption is reduced.

The application discloses a culture method for propagating Brachythecium populeum, and belongs to the technical field of Brachythecium populeum tissue culture. The application uses sporangium as an explant to propagate Brachythecium populeum, and quickly obtains Brachythecium populeum spores with a high germination rate, establishes a regeneration system of Brachythecium populeum, lays a foundation for large-scale propagation of Brachythecium populeum, shortens the propagation cycle of Brachythecium populeum, and better maintains excellent properties. The application first establishes a method for culturing Brachythecium populeum by using spores, fills the blank of the prior art, and provides a technical basis for propagation, seed preservation, preparation of protoplasts, recombination experiments and gametophyte culture of Brachythecium populeum.
