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.

preparation example Construction

[0056] 2) preparation of rooting agent aqueous solution: indole butyric acid is dissolved with alcohol, is made into 2g / L rooting agent aqueous solution, and then is placed in refrigerator fresh-keeping layer and preserved for subsequent use;

[0057] 3) Preparation of cuttings: from the perennial hibiscus mother plant (lemon black tea), a robust semi-lignified branch with a length of 10 to 12 cm is cut for use as cuttings, and the top of the cuttings has 2 to 3 half-cut leaves; according to the physiological lower end alignment, After bundling, first soak the lower incision of the cuttings in water for 5-10 minutes, then use the carbendazim solution to disinfect the incisions, and finally soak the cuttings base in the rooting agent aqueous solution for 1 minute, and then place 3-4 cm of the cuttings base in the water. Step (2) is soaked in the prepared rooting agent aqueous solution for 1 minute;

[0058] 4) Cutting: make a small hole in the substrate, insert the cutting into...

Embodiment 12 and 13

[0085] Embodiments 12 and 13 are different from Example 6 in that: the 0.1%~1% aqueous solution of fermenting inoculum is poured through and replaced with clear water; Step 3) in the preparation of cuttings, the aqueous solution of fermented inoculum is also replaced by clear water to carry out the incision. Disinfection treatment; in the management after cutting, replace the aqueous solution of fermentation inoculum with water to spray cuttings.

[0086] After 45 days, the status of the cuttings under different treatments is shown in Table 4 and image 3

[0088]

[0089] It can be seen from Examples 10 and 11 in the above table that after the substrate is subjected to high-temperature sterilization treatment, the functional probiotics cannot achieve the purpose of inhibiting the growth of pathogenic bacteria, and compared with Examples 5 and 6, the rot rate of cuttings can be greatly improved, Affect surviva...

Abstract

The invention discloses a hibiscus cutting substrate and a hibiscus cutting method under high temperature conditions. According to the volume ratio of the cutting substrate, 10-60 parts of urban landscaping waste compost, 0-50 parts of peat and 40-50 parts of perlite are uniformly mixed. On the one hand, the present invention introduces a variety of functional probiotics into the cutting matrix by adding composted urban greening waste that has been decomposed by a compound fermentation bacterial agent in the matrix, and utilizes the symbiotic synergy or synergy among various microorganisms in the flora It competes with the remaining pathogenic bacteria in the soil for nutrients and various living conditions, and competitively inhibits soil-borne diseases; at the same time, it uses the antagonism between microorganisms to inhibit the growth of pathogenic bacteria that cause root rot, reduce the rot of cuttings, and increase the growth of cuttings. Survival; on the other hand, using the water retention and fertility characteristics of urban landscaping waste compost, it can still promote the growth of plant roots under high temperature conditions, ensure the survival and later growth of cutting seedlings, and reduce the cultivation time and cycle of cutting seedlings.

Description

technical field [0001] The invention relates to the field of plant breeding and planting, in particular to a cutting substrate of hibiscus and a method for cutting of hibiscus, particularly a cutting substrate of hibiscus and a cutting method of hibiscus under high temperature conditions. Background technique [0002] Hibiscus (scientific name: Hibiscus rosa-sinensis Linn.) is a perennial woody flower of the genus Hibiscus in the Malvaceae family. It can bloom all year round under moderate temperature, and its flower 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 shape, hibiscus has not only become a popular potting material in the European and American markets, but also the continent flower of Hawaii, the national flower of Malaysia, Tainan, Taiwan and Guangxi. The city flower of Nanning. [0003] Cuttings are a relatively mature a...
