The invention relates to the propagation of Sargassum thunbergii, in particular to a method for quickly propagating the Sargassum thunbergii by a method of main branch fragment tillering, which comprises the following steps: 1) alcohol with a volume concentration of 75 percent used by the main branch of the Sargassum thunbergii is adopted for dipping the main branch for 25 to 23 seconds; and thena plurality of disinfected seawater is adopted for quickly washing the main branch for 3 to 4 times; 2) the main branch of the Sargassum thunbergii strain is sheared into fragments with a length of 2to 3cm; the fragments are arranged in a container to culture; universal ES seawater culture liquid is adopted as a medium for ventilation culturing; and when the tillers of the fragments can achieve 1.5 to 3.5cm, the fragments are taken out from the container and the tillers are cut off by a disinfected bistoury; and 3) the cut off tillers are continuously propagated and cultured by adopting the conditions in the step 2) or directly used for the large-scale gripping mariculture. The method is simple to be operated and low in cost; regenerated seedlings can be produced in a circularly; moreover, the method plays the remarkable role of protection on the natural environment.

The invention relates to the technical field of plant tissue culture application, in particular to a system and an application method for increasing the transplanted seedling emergence of "King Violet" grape test-tube seedlings. Cut the young shoots of the grape plants, remove the leaves, cut them into single-bud stems, inoculate them into the culture medium after sterilization, and obtain test-tube seedlings suitable for in vitro culture after subculture. Transplanting the lower section and cutting the upper section, the test-tube seedlings changed from one to two, and the "Violet King" grape test-tube seedling transplanting system controls the temperature, humidity, and light in the small plastic shed, which not only increases the number of grape test-tube seedlings. The emergence of domesticated transplanted seedlings improves the survival rate of test-tube seedlings of grapes, reduces production costs, can also reduce the height of tissue cultured seedlings, and overcomes the disadvantage of inconvenient management of creeping growth after transplanting.

The invention provides a novel method for breeding kelp seedlings with a gametophyte cloning method, comprising the following steps of: respectively separating a female cell on a female gametophyte and a male cell on a male gametophyte under a microscope by using a capillary tube separation technology; then respectively cloning the female cell and the male cell by using a cloning vegetative propagation technology to respectively grow the female cell and the male cell into female and male gametophytes; continually breeding the gametophytes; when the gametophytes are bred to a fixed amount, damping a formed cell cluster by a cell stamping machine; mixing the female and male gametophytes and respectively releasing ova and sperms by the female and male gametophytes to spontaneously fertilize;putting fertilized zygotes into nutritive salt to be cultured; and after 10 weeks, obtaining seedlings with the height of about 1.5 cm. According to the invention, a fertilization process and the control of temperature and illumination are realized by manual operation, so that the growth period of offspring seeds is greatly shortened; meanwhile, the female cell and the male cell are separated from the gametophytes by using the capillary tube separation technology to clone and culture, so that the quality and the yield of the seedlings are improved, the cultivation of the kelp can be satisfied; and by utilizing the novel method, the cost for breeding the kelp seedlings is low.

The invention belongs to the technical field of plant breeding and particularly relates to an efficient breeding method for maca seedlings. The method is used for solving the technical problems of the existing maca reproduction technologies that the yield of seedling raising is low, the quality is poor, and labor and time are consumed. The technical scheme of the invention is as follows: the efficient breeding method for the maca seedlings comprises the following steps: (a) carrying out seed treatment; (b) preparing nutritional soil; (c) carrying out sowing; (d) carrying out seedling raising management; and (e) carrying out seedling hardening. The method can be applied to the breeding of the maca seedlings, the germination accelerating speed of seeds is high, the emergence of seedlings is even, and the rate of emergence is high; the density of sowing and the quality and yield of the seedlings are greatly improved; the cycle of seedling raising is shortened, the phenology and season of cultivation of the seedlings are controllable, and the survival rate of cultivation is high; and the input-output ratio of seedling raising is high, and the benefit is remarkable.

The invention provides a biological cultivation method of a sea horse, which comprises the following steps of: establishing a cultured biological system, cultivating a newborn sea horse, cultivating a young sea horse and cultivating an adult sea horse. In the sea horse cultivating technology provided by the invention, the supply of bait under an industrial condition is ensured by establishing thecultured biological system, accelerating maturity and cultivating the bait; diseases are effectively prevented and treated and the surviving rate is increased; the mature rate and the seedling yield can be greatly increased; the surviving rate of sea horse seedlings is 62.38%; the nurturance surviving rate is 89.52%; the seedling yield per fetus is 405.2; the unit yield is 0.613kg / stere; and the biological cultivation method is a new technology capable of realizing industrial cultivation.

The invention provides a large-scale mappia pittosporoides direct seeding and seedling method. The method includes a series of steps such as nursery site requirements for mappia pittosporoides direct seeding and seedling, greenhouse erection and compartment division, seed pretreatment, seeding, management before germination, preliminary management after germination, seedling transplantation, field management after transplantation, etc. Seedlings obtained through the method achieve a low infection rate, high robustness, a high transplantation survival rate, as well as strong rootstocks; the operation is simple and convenient; the method is applicable for propagation technologies for mappia pittosporoides field seedling, and overcomes the limitations of the conventional seedling technologies.
