The invention discloses a method for promoting the germination of miracle fruit seeds and improving the survival rate of seedlings, which is mainly realized through steps such as seed selection, seed disinfection, ultrasonic treatment, seed dormancy breaking treatment, seed germination, and seedling transplantation; The technology of breaking seed dormancy by using growth regulator control and variable temperature treatment, including the use of appropriate concentration of growth regulators and suitable variable temperature treatment substrates and temperature changes, greatly shortens the germination time of miracle fruit seeds. The invention uses ultrasonic waves to treat seeds, and adopts appropriate temperature and light treatment to improve the germination rate, germination potential and germination index, and adopts a suitable seedling raising substrate, and the survival rate of seedlings is also high.

The invention discloses a method for cutting propagation of cynaroides king protea. The method comprises the following steps of: selecting a cynaroides king protea maternal plant, scissoring a twig from a position above a semi-lignified part as a cutting slip, and keeping 4 to 6 leaves; preparing a substrate by mixing peat and pearlite according to a volume ratio of 4:6, adjusting the ph value to be between 5.5 and 6.5 and the ec value less than 0.5; soaking the basal part of the cutting slip by using 1,000 ppm indole-3-butyric acid solution, and air-drying the basal part immediately after soaking 15 minutes; controlling the cutting depth to be 1 / 3 to 1 / 4 of the length of the cutting slip; and performing management according to a conventional technique after cutting, and performing field transplantation after seedling emergence. The application of the technique ensures that the survival rate of the cutting propagation of the cynaroides king protea reaches over 90 percent, and the propagation cycle is shortened to be 40 to 60 days. The obtained seedling is good in quality and has a long service life, and the offspring performance characteristics are stable and consistent, so a technical base for selecting and cultivating a new species with excellent characteristics is established. The method is simple and convenient, and has a low cost, a high seedling survival rate and a good market application prospect.

The invention relates to a medium for seedling raising and cultivation and a preparation method of the medium, belonging to the technical field of agricultural production. In order to solve the problems that the existing cultivation medium uses non-renewable resources such as plant ash and vermiculite as raw materials, and environmental damages are caused because vermiculite and perlite cannot be decomposed easily, the invention provides the medium for seedling raising and cultivation and the preparation method of the medium. The sources of raw materials are wide, the raw materials are degradable materials and pollution is not caused to the environment; and since chemical fertilizers are not used, the soil structure is not damaged. By using recycled aggregate, the problem of recycling building wastes is solved; and since kieselguhr and seaweed fertilizers take an effect of improving the soil and contain rich elements, the needs of growth of different plants can be met. By using the medium for seedling raising and cultivation provided by the invention, the survival rate of cultivated seedlings is high, the cultivated seedlings grow well and the situation that weeds grow is avoided.

The invention discloses a tissue culturing and propagation expanding method for radix pseudostellariae toxin-free seedlings. The tissue culturing and propagation expanding method comprises the following specific steps: (1) obtaining toxin-free seedlings; (2) preparing a culture medium: weighing all the ingredients according to the following matching amounts: 7.07 g / L KNO3, 2.30 g / L NH4H2PO3, 3.4 g / L KH2PO4, 4.95 g / L MgSO4.7H2O, 4.7 g / L Ca(NO3)2.4H2O, 37.3 mg / L Na2.EDTA and 27.8 mg / L FeSO4.7H2O and adding gellan gum into the culture medium to form a solid culture medium; (3) performing tissue culture and amplification on the toxin-free seedlings; (4) propagating the toxin-free seedlings. According to the method, required nitrogen, phosphorus and potassium contents and microelements are provided for radix pseudostellariae growth. In a propagation expanding and culturing process of the radix pseudostellariae toxin-free seedlings, the culture medium is not replaced in the whole process; furthermore, no plant hormone is added, a culture process is simplified, labor cost is saved, and the tissue culturing and propagation expanding efficiency is greatly improved. A clean bench is not needed by tissue culturing and propagation expanding operation, a requirement for operators is low, simpleness and quickness in operation are achieved, the microbial pollution rate is low, the seedling survival rate is high, and production cost is greatly reduced.

The invention discloses a method for cutting and propagating a chamelaucium plant. The method comprises the following steps: collecting a healthy plant without diseases and pests as a female parent material and scissoring newborn tender twigs above the half-lignifying position of the female parent material as cutting ears; dipping the basic parts of the cutting ears by 500-2000ppm of indole-3-butanoic acid solution and then carrying out bactericidal treatment on the cutting ears by a solution with 1500 times of gejunqing of 2.5% after drying in the air; and taking the cutting depth as 1 / 3-1 / 4 of the length of the cutting ears, managing by a conventional technology after cutting, and carrying out field transplantation after the roots of the cutting ears grow out of the bottom of a seedling disk. By applying the method, the survival rate of the cutting and the propagation of the chamelaucium plant reaches more than 90%, and the propagation period is shortened to 35-40 days. The obtained chamelaucium seeds and seedlings have superior quality and long service life, so that the popularized planting of the chamelaucium plant becomes possible. The invention has simple and convenient method, low cost, high survival rate of the seeds and the seedlings and favorable market application prospect.

The invention relates to a method for improving the germination rate of Paphiopedilum grandiflorum seeds and its cultivation method. More specifically, the present invention provides a method for improving the seed germination rate of Paphiopedilum grandiflora, the method comprising the steps of: (1) carrying out artificial pollination after the flowering of Paphiopedilum grandiflora; and (2) after pollination After 180 days to 240 days, the seeds were obtained and sown on a seed germination medium, thereby obtaining buds from the seeds. The present invention also provides a method for cultivating Paphiopedilum grandiflora, which adopts the method for increasing the germination rate to increase the germination rate of seeds.
