Hibiscus rosa-sinensis Linn cutting medium and Hibiscus rosa-sinensis Linn cutting method under high-temperature condition

Abstract

The invention discloses a Hibiscus rosa-sinensis Linn cutting medium and a Hibiscus rosa-sinensis Linn cutting method under a high-temperature condition. The cutting medium is prepared by uniformly mixing the following components in parts by volume: 10-60 parts of urban landscaping waste compost, 0-50 parts of peat and 40-50 parts of perlite. On the one hand, the urban landscaping waste compost decomposed by a composite fermentation microbial agent is added into the medium, and multiple functional probiotic floras are introduced into the cutting medium and fight with residual pathogenic bacteria in soil for nutrition and various survival conditions by utilizing symbiotic cooperation or synergism of multiple microorganisms in the probiotic floras, so that soil-borne diseases are competitively inhibited; meanwhile, growth of the pathogenic bacteria causing root rot is inhibited through antagonism among the microorganisms, rot of cutting slips is reduced, and survival of the cutting slipsis improved; and on the other hand, the characteristics of water retention and fertility of the urban landscaping waste compost are utilized, growth of plant root systems can still be promoted underthe high-temperature condition, survival and later-period growing power of cutting seedlings are guaranteed, and the cultivation time and period of the cutting seedlings are shortened.

Description

technical field [0001] The invention relates to the field of plant breeding and planting, in particular to a hibiscus cutting substrate and a hibiscus cutting method, in particular to a hibiscus cutting substrate and a hibiscus cutting method under high temperature conditions. Background technique [0002] Hibiscus (scientific name: Hibiscus rosa-sinensis Linn.) is a perennial woody flower of the genus Hibiscus in Malvaceae. It can bloom all year round at a suitable temperature, and its color and pattern are changeable. There are more than 10,000 cultivars in the world. Because of its excellent potting characteristics such as good flowering, good branching and compact plant type, hibiscus has not only become a popular potting material in European and American markets, but also the state flower of Hawaii in the United States, the national flower of Malaysia, and Tainan City and Guangxi in Taiwan, China. The city flower of Nanning. [0003] Cutting is a relatively mature rapi...

AI Technical Summary

Problems solved by technology

In the hot summer and winter, due to the need to maintain a constant and suitable temperature, the operating cost of the greenhouse is high, and it is not suitable for cuttings.

And the inventor found that under the condition of continuous high temperature in simple gardening facilities, using the substrate of classic formula to carry out hibiscus cuttings, although the water holding capacity of peat is relatively high, its wilting water content is also relatively high

If you don’t pay attention to timely irrigation during the management process, the hibiscus cuttings will die. If the water content of the substrate is maintained by artificial watering, it will easily cause root rot seedling blight under high temperature and high humidity conditions.

In short, in the simple gardening facilities with poor conditions, the survival rate is low under high temperature weather, which affects the rooting and growth of new branches, prolongs the seedling cultivation cycle, and cannot meet the needs of production.
