Embodiment 1

[0017] Sawdust fermentation treatment: The C-N ratio of sawdust is as high as 130.6, which seriously restricts the activity of microorganisms in the fermentation process. Therefore, before fermentation, 2.5Kg of urea is added to each cubic meter of sawdust to increase the N source, and a small amount of gypsum powder is added to adjust the acidity and alkalinity (pH6.5 or so ). When fermenting, the moisture content is controlled at about 60%, and the plastic film is put on the cover after fully stirring. During the fermentation process, the temperature in the substrate heap can reach 60-65°C, even as high as 70°C in summer. After 5-7 days of fermentation, spread out the pile to cool down, and completely remove the toxic gas. Fully fermented sawdust is yellowish brown, high-temperature disinfection before use, and sprayed with 15%-20% formalin solution to sterilize, and adjust the physical and chemical properties for future use.

Embodiment 2

[0023] Application of embodiment 2 composite matrix in cyclamen cultivation

[0024] With the substrate of the formula of embodiment 1, be used for the cultivation of cyclamen, use peat substrate (peat: perlite=3: 1) as contrast (CK) cultivation under the same conditions (cultivation under greenhouse conditions, this greenhouse has fully automatic Temperature control and ventilation facilities can ensure a relatively stable and suitable growth environment for the test materials during the test period). The results are shown in Table 1:

[0025] Table 1 The comprehensive evaluation index of plant morphological indicators of cyclamen cultivated in composite substrate

[0026]

[0027] It can be seen from Table 1 that the comprehensive evaluation index of cyclamen morphological indicators is higher than that of the traditional peat matrix formula, and the cost of the matrix is ​​greatly reduced.

Abstract

The invention is provided with a cyclamen culture medium made of wood chips. The culture medium mixes the zymolytic wood chips and soya bean stem powder in a volume rate of 6-8:2-4. The compound medium can improve the medium physicochemical property, reduce badness reaction of the single medium and promote the growth of the cyclamen, decrease the turfy usage dosage and lowered the cost in a precondition of ensuring the quality, achieve the resource utilization of the coco peat.

Description

technical field [0001] The invention relates to a resource utilization technology of agricultural organic matter, in particular to a cyclamen cultivation substrate prepared from sawdust. Background technique [0002] Cyclamen percicum Mill. is a perennial bulbous flower of the genus Cyclamen in Primulaceae, and it is mostly cultivated as an annual in potted flower production. It has a wide variety, unique flower shapes, bright colors, and long flowering period. It is deeply loved by people and has become an enduring annual potted flower. It is one of the main potted flowers in winter and spring. [0003] Peat is a complex hydrophilic polymeric system with multi-component, multi-fraction and semi-colloid properties transformed from marsh plant remains. It has high organic matter and humic acid content, rich fiber content, loose and porous, good air and water permeability, large specific surface area, strong adsorption and chelation ability, strong ion exchange ability and sa...
