Embodiment 1

[0017] Fermentation treatment of corncobs: The C-N ratio of corncobs is as high as 74.6, which seriously restricts the activity of microorganisms in the fermentation process. Therefore, 2.1Kg of urea is added to each cubic meter of corncob powder before fermentation 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 4-6 days of fermentation, spread out the pile to cool down, and completely remove the toxic gas, and the fully fermented corn cob powder is dark gray. High-temperature disinfection before use, and spray 15%-20% formalin solution to sterilize. Adjust physical and chemical properties for later 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] matrix

[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 provides a culture medium for cyclamen. It is prepared with maize-ear refuse and peanut shell through fermentation with volumetric ratio being 5- 7: 3-5. The combined medium can improve physical chemical properties, reduce adverse effect of single medium, promote cyclamen growth, and reduce peat consumption and production cost. It makes use of maize-ear refuse, and possesses outstanding social benefit, economical benefit and environmental benefit.

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 corncobs. 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 s...
