The alfalfa non-separation quick rooting and cutting device and an application method thereof further disclose an alfalfa non-separation quickly rooting cutting method, and the alfalfa non-separation quickly rooting cutting device and the application method thereof have the advantages of being high in efficiency and survival rate.

The invention relates to a method for multi-layer breeding of seedlings by using a heating incubator, belonging to a method for cultivating plant seedlings. A box with a bottom inner diameter of 200cm×100cm and a height of 30cm is made of color steel composite board, and a geothermal wire with a resistance of 33 ohms / m is laid on the bottom of the box to form a heated and temperature-controlled seedling box. Put the seedling box on the seedling rack, fill the seedling box with a 15cm thick seedling substrate, and pour it with 2000 times of carbendazim solution, insert the cut cuttings into the substrate after treatment, and keep the temperature in the box at 27-29°C , every 8‑10 days, the seedling box is poured with a 2000-fold carbendazim solution once to keep the substrate in the box moist. The seedling time is 30-40 days, and the incubator seedlings are obtained. The method of the invention has a seedling rooting rate of more than 92.0%, a large number of root systems and even distribution, secondary lateral roots, and relatively mature root development. Compared with flat seedling raising, multi-layer seedling raising increases the number of seedlings per unit area, which is suitable for factory breeding of seedlings.

The invention discloses a non-tube rootage method for a camellia oleifem tissue culture seedling. The method comprises the steps of inoculating a micro-branch which has 4-5 leaves, a slight red and brighten top leaf, a green stalk and height being 2-4cm and is obtained by performing subculture proliferation on a camellia oleifem seedling onto a root primordium induction culture medium for culturing till the base part generates a white root primordium, wherein each litre of the root primordium induction culture medium contains NAA of 3.0-5.0mg, and the rest root primordium induction culture medium is 1 / 2HB culture medium; taking the micro-branch with the white root primordium growing on the base part, washing the culture medium of the base part without roots and shoots, dipping with GGR (green plant growth regulator) of 200-600mg / L after filtering, instantly cutting onto a cutting medium, watering enough root fixed water, ensuring sufficient water and fertilizer supply during the growth period, and growing the micro-branch to a rooted seedling, wherein the cutting medium is formed by uniformly mixing 2-6 parts of yellow subsoil and 1-2 parts of plant ash. The method adopts non-tube rootage and breaks through the traditional mode in which the root system is induced in a tissue culture bottle, rootage and domestication are organically combined, direct rootage of the camellia oleifem tissue culture seedling outside a tissue culture bottle is realized, and the method has the advantages of short rootage time, well developed root system, absorption function and high transplantation survival rate.

The invention belongs to the field of tissue culture, and relates to a rootless tissue culture method of Lycoris and a cultivation method of Lycoris. The invention provides a method for rootless tissue culture of Lycoris: inducing bulbs in an induction medium to obtain adventitious buds; the induction medium is based on MS, and further includes: 0.5-3.0 mg / L 6-benzylaminopurine, 0.5 ~1.5mg / Lα-naphthaleneacetic acid, 30g / L sucrose and / or white sugar and 6~8g / L agar; culture adventitious buds in proliferation medium to obtain rootless tissue culture shoots; proliferation medium is based on MS, and also Including: 3.0-5.0mg / L 6-benzylaminopurine, 0.5-1.5mg / L α-naphthaleneacetic acid, 0-3mg / L forchlorfenuron, 30g / L sucrose and / or white sugar, 0-1mg / L thidiazuron and 7-8g / L agar; the number of proliferation culture is 1-5 times. The rootless tissue culture method for lycoris provided by the invention has a high survival rate.

The invention relates to a heating foam particle nursery box and an application thereof, belonging to a method for cultivating plant seedlings. Spread the geothermal wire with a resistance of 33 ohms / m on the bottom of the color steel composite board box to form a seedling box. Wrap the base of the cuttings with a nutrient bag and put them into the seedling box one by one. Fill the upper space with foam particles 1-3cm in size to about 2cm from the top buds. Cover the gaps between the cuttings with newspapers and cover the top with 1-3cm. 2cm thick fine sand forms a relatively airtight space under the newspaper. The temperature in the space is kept at 27-29°C. Every 7-8 days, the seedling box is poured with a 2000-fold carbendazim solution once to maintain the matrix in the box. moist. The seedling time is 30-40 days, and the incubator seedlings are obtained. The method of the invention has a seedling rooting rate of more than 95.0 percent, a large number of roots and even distribution, and improves the transplanting survival rate of the mulberry seedlings.
