The invention belongs to the technical field of nano material preparation and performance study, and discloses a preparation method of silver nano particles and a method for facilitating germination of cucumber seeds and growth and development of seedlings with the silver nano particles. The preparation method comprises the following steps that an AgNO3 aqueous solution is taken; PVP (Polyvinyl Pyrrolidone) is added; an amino acid aqueous solution which is isometric with the AgNO3 aqueous solution and has reducibility is added after PVP is dissolved completely; when a color of a reaction system graduates into brown and is optically transparent, the nano particles are generated and are smaller in dimension; centrifugal treatment is performed; an obtained supernatant is recollected into an initial reaction container; a precipitate obtained at the bottom of a centrifugal tube is stored in deionized water; and an Ag nano particle solution is obtained. The silver nano particles are prepared by taking amino acid as a reducing agent, so that the silver nano particles have good biocompatibility. PVP is taken as a dispersing agent for preventing aggregation of the nano particles. A requirement of the whole preparation on reaction conditions is not high; scale production is easy to realize; and the provided nano particles can be applied in agricultural production.

The present invention provides a control device and method for pressure cooker for brown rice germination and cooking. The users can quickly make the brown rice germinate under the optimum environment condition including proper temperature, and directly cooks the germinated brown rice. In addition, the users can cook germinated brown rice under all kinds of germinating states by making the brown rice germinate under the different conditions. As a result, the users effectively make the brown rice germination in a short time, and cook the brown rice according to personal like.

The invention discloses a method for regenerating a rose into a complete plant. The complete plant is prepared by obtaining a rose sterile seedling, inducing a somatic embryo, performing enrichment culture on the somatic embryo and germinating the somatic embryo into a seedling. In the method, the culture period is short; the survival rate is high; the proliferation multiple is high; the characteristics of a parent strain can be maintained completely; and the obtained somatic embryo is convenient to store for a long time and is an important receptor material for genetic transformation.

The invention provides an improved bioassay method for an antagonistic bacterium, namely a double-layer culture medium filter paper sandwich method, which belongs to the technical field of a bioassay method for a strain to be tested which is required to be adopted for biological pesticide development. The antibacterial activity of the antagonistic bacterium on plant pathogenic fungi is determinedthrough the simple and easy procedures of manufacture of a sterile filter paper sheet die, manufacture of an upper culture medium and a lower culture medium, shift-in and shift-out of the sterile filter paper die, culture of the antagonistic bacterium to be tested and the target pathogenic fungi, measurement of experimental results and so on, and the antagonistic bacterium with application value can be reasonable screened out. The simple, convenient and quick novel method for implementing bioassay of the antagonistic bacterium has technological innovation. The method can truly reflect the antibacterial ability of metabolites of the strain, has the advantages of good test stability, good repeatability, cheap materials, simple and convenient operation, short experimental period and so on, can realize large-scale determination of a plurality of antagonistic bacteria on a plurality of the pathogenic fungi, and has good function on research of the biological and ecological stability of theantagonistic bacteria.
