The method comprises the following steps: (1) male loaches and female loaches living for 2 to 3 years are chosen and are respectively fed for 40 to 50 days; (2) each female loach receives subcutaneous injection of parturition hastening medicine liquid at 0.0500to 0.0575 mL/g; (3) after the subcutaneous injection, the male loaches and the female loaches are respectively fed continuously for 12 to 14 days; (4) the male loaches and the female loaches are fed in a mixed mode, after copulation and egg-laying are completed, the female loaches and the male loaches are taken away, and after eggs are hatched, an average hatchability is over 99.8%; and (5) loach fries are fed. The method solves the problems that fry rate is low in natural breeding, copulation is incomplete, hatchability for a germ cell is low, the fries are threatened by small natural enemies so that ...

The invention relates to a one-step after-ripening method of a magnolia sieboldii seed. The method comprises the steps of soaking the seed with mixed solution of 1.10-1.30mg.L-1 of 6-benayl aminopurine and 2.10-2.30mg.L-1 of 2,4-dichlorphenoxyacetic acid, then fishing the seed out, evenly stirring the seed with river sand and then packaging into a wood tank with good air permeability; and covering a plastic film and arranging the wood tank inside a room to carry out 93-114d of poikilothermic treatment, wherein the temperature range and time are that the temperature during the day is 18+/-2 DEG C, the treatment time is 16 hours, the temperature at night is 7+/-2 DEG C, and the treatment time is 8 hours, and then the seed develops to become a mature embryo cotyledon seed. According to the method, not only are the difficulties that the seeds do not germinate or a few of seeds germinate in the same year of being sown and the rooting percentage of vegetative propagation such as cottage is very ...

The invention relates to an integrated detoxification method of vitis vinifera in a test tube, belonging to the technique of plant propagation. The method comprises the following steps: (1) conducting water cultivating on dormant branches of the vitis vinifera to impel dormant buds to sprout, employing treated stem tips as explants for standby; (2) inoculating the cut vitis vinifera stem tips to a minimal medium added with 0.08-0.13mg.L of indolebutyric acid, 2.20-3.30mg.L of gibberellins, 5g.L of edible sugar and 8.0g.L of agar stripes for cultivating to remove a grapevine fanleaf virus and a grapevine leafroll associated virus; (3) controlling the cultivating temperature to be 45-48 DEG C, and cultivating for 51-57 days; and (4) when the stem tip grows to 1.0cm, cutting 0.03-0.05cm of stem tip to further carry on nontoxic seedling cultivation. Through the application of the integrated detoxification method, the removal rates of the grapevine fanleaf virus and the grapevine leafroll associated ...
