The plant growth regulator for delaying the harvesting time of the cut-flower roses comprises the following raw materials: 1-naphthylacetic acid, abscisic acid, cytokinin, a water-soluble fertilizer containing amino acid and monopotassium phosphate. According to the plant growth regulator for delaying the harvest time of the cut-flower roses, provided by the invention, the 1-naphthylacetic acid, the abscisic acid and the cytokinin are compounded together, so that the flower blooming process can be effectively delayed, and the harvest time is delayed. The plant growth regulator takes plant hormones as main raw materials, has the advantages of environmental friendliness, safety, harmlessness, low cost and the like, and further accurately regulates and controls the flower development process of the cut-flower roses by ensuring normal hormone signal transduction and development regulation and control. The growth regulator can effectively delay the harvesting time, powerfully ensures that the cut-flower roses are accurately marketed as required and the quality of the cut-flower roses is improved, and remarkably improves the production benefits and the industrial value.

The invention belongs to the technical field of agriculture, and particularly relates to a degerming and seedling formation solution, a preparation method, an application method and a method for promoting seed germination and seedling formation. The degerming and seedling formation solution provided by the invention comprises gibberellic acid, indoleacetic acid, naphthylacetic acid, coptis chinensis and carbendazim, and the combination of coptis chinensis extract, carbendazim and growth hormone (gibberellic acid, indoleacetic acid and naphthylacetic acid) in a specific proportion has a synergistic inhibition effect on alternaria alternata and has a promotion effect on seed germination and seedling formation. The invention provides the preparation method of the degerming and seedling forming solution, and the application is simple. According to the application method of the degerming and seedling forming solution, the operation steps are simple, convenient and efficient, and the seedling forming efficiency is remarkably improved. The result of the embodiment shows that the germination rate of the Sinojackia xylocarpa seeds reaches 100% after the optimal treatment is performed for 15 days, and the survival rate of the seed seedlings reaches 96.67% after the optimal treatment is performed for 30 days.

The invention discloses a dendrobium officinale protocorm-like body efficient proliferation culture medium and an application method thereof.The culture medium takes 1 / 2 MS as a basic culture medium, 30 g / L of mashed potatoes, 30 g / L of sucrose, 7 g / L of agar, 1 g / L of activated carbon, 0.2 mg / L of naphthylacetic acid (NAA) and 2 mg / L of 6-benzylamino adenine (6-BA) are added, pH is adjusted to 5.5-6.0, and preparation of the dendrobium officinale protocorm-like body efficient proliferation culture medium is completed through mother liquor preparation, ingredient mixing, pH adjustment and 121 DEG C high-pressure steam sterilization for 30 min. During application, the protocorm-like body needs to be inoculated into the culture medium through high-pressure steam sterilization, ultra-clean bench preparation, standardized split charging and sterile inoculation operation, and then is cultured under the conditions of (27 + / -2) DEG C, 12h / d illumination and 4000-5000lx. According to the method, the proliferation coefficient of the protocorm-like body cultured for 30 days is not lower than 5.0, the survival rate is not lower than 95%, browning is avoided, large-scale proliferation of the dendrobium officinale protocorm-like body can be efficiently achieved, and technical support is provided for follow-up research and production.

The invention belongs to the technical field of agricultural biology and seed engineering, and relates to a growth-promoting stress-resistant rape seed pelleting agent and application. The pelleting agent has the functions of growth promotion, disease resistance (clubroot), pest killing and stress resistance (stain resistance and cold resistance), and is formed by scientifically compounding an inert filler, a composite growth promotion component (including melatonin, naphthylacetic acid and abscisic acid), a bactericide (fluazinam or trichoderma), a broad-spectrum insecticide (70% thiamethoxam), a plant growth regulator (brassinolide or selenium medicament), an adhesive and an auxiliary agent. When an optimal formula of the composite preparation of fluazinam (the ratio of pesticide to seeds is 1: 100) and brassinolide is used, the cost is only about 0.67 yuan per mu, the yield can be increased by about 14 kilograms, the stable net income increase of 85-219 yuan per mu can be realized, and the input-output ratio is as high as 1: 126-1: 337. The invention provides an efficient, safe and comprehensive seed treatment scheme, and has important application value for guaranteeing stable and high yield of rape.

The invention provides a buxus sinica blooming inhibitor for effectively inhibiting the blooming of buxus sinica, and belongs to the technical field of plant growth regulation, the inhibitor comprises the following components: naphthylacetic acid, gibberellin and humic acid, and can obviously inhibit the blooming process of the buxus sinica, reduce the nutrient waste caused by reproductive growth and maintain the good growth state of the buxus sinica.

The invention relates to the technical field of sculellaria barbata culture, in particular to a sculellaria barbata culture medium and a preparation method thereof The sculellaria barbata culture medium is prepared from an MS culture medium and a basic raw material according to the mass ratio of (6-7): 1, and the basic raw material is prepared from the following raw materials in parts by weight: 2-4 parts of novel nano silicon dioxide, 0.05-0.08 part of cerous nitrate, 1-2 parts of an organic fungicide, 0.7-0.8 part of 6-benzyladenine, 0.2-0.4 part of alpha-naphthylacetic acid, 0.1-0.3 part of jasmonic acid methyl ester and 2-4 parts of a functional additive. According to the invention, cell wall stability is enhanced and hormone slow release regulation is realized through novel nano silicon dioxide, and cerium nitrate is improved to activate a flavonoid compound synthetase system; the organic fungicide inhibits pathogenic bacteria and promotes nitrogen conversion by secreting lipopeptide antibiotics and nitrogenase systems; and the functional auxiliary agent realizes efficient retention and stable release of the active components.

The invention discloses a method for expanding propagation and conservation of thermophilic rare mangrove black plum in a marginal area. According to the method, a waste salt pan (field) with sufficient illumination in the northern marginal area is selected, and a series of measures such as soil temperature increasing and nutrient increasing, close planting, naphthylacetic acid and gibberellin mixed solution spraying and straw heat preservation (winter) are taken, so that a natural breeding mode with a thermophilic environment and obligate outcrossing characteristics is built, and the growth of mangrove prunus salicina plants and the stability of communities are accelerated. The method plays an important role in the aspects of rescue retention of rare and endangered herminium cerasus germplasm resources, maintenance of herminium cerasus germplasm resources and genetic diversity and the like, also provides possibility for northward migration, introduction and propagation of herminium cerasus, and ensures continuous and sustainable growth of herminium cerasus in marginal areas.
