The invention belongs to microbial fermentation, and particularly relates to a preparation method of a probiotic inoculum for preventing replant disease of greenhouse cucumbers. The preparation method comprises a fermentation step: inoculating a probiotic inoculum producing strain into a sterile culture medium containing a carbon source, a nitrogen source, inorganic salt and water; carrying out aerobic fermentation under the conditions that the temperature is 30-37 DEG C and the pH value is 7.2-7.6 in the fermentation process, wherein the producing strain is a mixture of Bacillus subtilis, Bacillus licheniformis, Trichosporon behrendii, Paecilomyces lilacinus, Streptomyces microflavus, Bacillus polymyxa and Metarhizium anisopliae of the same mass; and adsorbing the final fermentation product, and immobilizing on grass carbon to obtain the probiotic inoculum. The preparation method solves the defects of replant disease, root rot, blight, nematode disease and the like in the existing greenhouse vegetable-cucumber planting technology, has the advantages of low production cost, short fermentation period and high flora density, and can effectively prevent seedling death, seedling yellowing, blight, mosaic disease, root rot and other ecological symptoms of soil. Meanwhile, the preparation method can promote the growth of roots, loosen the soil, strengthen the seedlings and degrade the residual pesticides and fertilizers, and has an effect of obviously restoring the soil ecosystem. By using the preparation method, the yield of greenhouse cucumbers can be increased by 15-20% in one season.

A preparation method of probiotic microbial inoculum for prevention of genseng replant diseases belongs to the microbial fermentation field, and comprises a fermentation step: producing strains of the probiotic microbial inoculum are inoculated onto an aseptic culture medium containing carbon source, nitrogen source, inorganic salts and water for fermentation, the fermentation process is aerobic mixed fermentation, the producing strains are selected from eight strains comprising Bacillus subtilis CGMCC1.1700 and the like. The probiotic microbial inoculum is a solid microbial inoculum prepared by adsorption and immobilization of a fermentation end product onto grass carbon. The preparation method solves the problem of the replant diseases existing in the ginseng planting technology in the prior art, can reuse soil in which ginseng is planted, has the advantages of low production cost, short fermentation cycle and high bacteria density, can effectively prevent soil ecological disease symptoms of dead seedling, yellow seedling, withering, flecked leaf, root rot and the like during ginseng planting, at the same time, can promote root growth, loosen soil and strengthen seedling, remove residues of pesticides and fertilizers, and has obvious effects on soil ecological restoration.

The invention discloses a disease-resistant and pest-resistant culture substrate based on agricultural wastes and a preparation method thereof, and relates to the technical field of soilless culture.The disease-resistant and pest-resistant culture substrate comprises the following components in parts by weight: 800 to 1000 parts of crop straw, 5 to 200 parts of edible-fungus chaff, 200 to 400 parts of livestock and poultry manure, 0.2 to 0.5 part of a straw decomposing agent, 50 to 100 parts of ash from a biomass power plant, 50 to 100 parts of coal slag, and 0.5 to 1 part of a microbial pesticide. The disease-resistant and pest-resistant culture substrate provided by the invention has the advantages of scientific proportion, comprehensive nutrition, sufficient nutrients, moderate bulk density, good ventilation and water permeability, and capability of being used as a seedling raising substrate of a plant in a seedling stage, and a culture substrate and a soil improvement conditionerfor a crop in a whole growth period. The disease-resistant and pest-resistant culture substrate provided by the invention comprises a large number of beneficial microorganisms, so the growth of the crop is promoted, and the occurrence of diseases and pests is effectively prevented and controlled.

The invention discloses a germination accelerating and rooting method for lily bulbs. The method comprises the steps of preparing a simple germination accelerating and rooting greenhouse and a rooting bed; defreezing the lily bulbs; disinfecting the bulbs, and treating a rooting accelerant; arranging the bulbs, and covering the bulbs by soil; controlling the temperature and the humidity in the simple germination accelerating and rooting greenhouse, and keeping proper moisture content of a matrix; performing large-field planting after germination accelerating and rooting are finished. Therefore, lily stems are rooted to be 1-3mm, and lily buds are 8-15cm long. According to the method, a refrigeration house condition is not needed, so that the cost is low; environment conditions such as proper temperature, proper humidity and darkness are supplied to stem rooting growth and bud germination through bulb germination accelerating and rooting treatment in the field greenhouse, so that the lily stem rooting growth and the bud germination are facilitated; the problem that high temperature in the early stage of lily growth affects the lily stem rooting growth and the bud germination is solved, and the lily cutting quality is improved.

The present invention provides a phosphorus solid-phase buffering system that can be spatially localized, i.e., banded on top of, or at specific depths, in media, e.g., soil, by which phosphorus concentrations in the media are reduced or maintained at levels sufficient for optimal plant performance. Also provided are methods for improving the cultivation of plants growing in different media. The present invention provides benefits, such as reduced water and pesticide requirements, reduced phosphorus leaching and runoff, and enhanced root growth. The invention can be used in connection with containerized or field-grown plants, e.g., crops, grasses, trees, and the like. The invention is particularly useful for greenhouse and nursery plants, ornamental propagation, vegetable and bedding transplants, and for turf used for stadium fields, golf courses, lawns and the like, where phosphorus leaching is particularly undesirable.

A self-contained plant cloning system and method for stimulating root growth from a stem of a plant. The system includes a reservoir having a base, one or more sidewalls, and an open upper end, defining an interior volume that can hold liquid. A rack rests on the upper end of the reservoir and can support a plant therein. A pump and cooling element are disposed in the reservoir and can be submerged in the liquid. The submersible pump is connected to one or more sprayers that mist liquid on the stems in order to stimulate root growth. As the pump is operated, it circulates the liquid in the reservoir. Liquid directly contacts the cooling element as it circulates in order to efficiently regulate the temperature of the environment in the reservoir.
