1 species selection
Article according to the local consumption habits, choose fruit length, straight fine, pointed, purple color, good taste of high yield, high quality and strong adaptability of cultivated varieties, such as zhejiang tomato 1 in tomato, hangzhou 2010.The scion varieties to choose lu bam.
2 grafting seedling
2.1 seeding time arrangement
Take specific seeding time batch sowing seeds, such as table 1.
Early spring temperatures low, slow growth of the stock, in order to ensure the grafting rootstock and scion thickness consistent, root stock seeding time than a scion 30 ~ 40 days in advance.Grafting to colonize interval of about 20 days.
2.2 seed treatment and planting
Wood seed with 500 mg/L gibberellin before planting seed 24 h, then remove with clean water, after air live in seedbed matrix;Live in the matrix seedbed scion seeds.After sowing covering film thermal insulation, moisture, and USES electric heating wire electric heating, the temperature control in 28 ~ 30 ℃.
2.3 seedling stage management
(1) temperature management Root stock information for 10 ~ 15 days after emergence, scion about 1 week after seeding emergence, when 50% of seeds unearthed, appropriately reduce relative temperature, generally in the 25 to 28 ℃, no more than 35 ℃ during the day, not less than 15 ℃ at night.Sunny noon timely ventilated take a breath, the night cover insulation layers.
(2) the humidity management Before the emergence of humidity is a bit high, reduce the humidity after emergence, half dry and wet as well, prevent the moderate growth and seedling diseases.Sunny substrate surface water not white, pale after water flooding in time, prevent the dry seedling substrate.
(3) points seedling seedling 2 leaves 1 at the time of the heart of, choose a sunny day in hole plate.Bed out survival after more see the light, moderate growth, cultivate strong seedlings.Scion adopts 72 cavity plate, stock by 50 holes or 72 cavity plate.
2.4 grafting
When the rootstock and scion 4 leaves 1 heart began to grafting, 1 day before to the root water flooding.Grafting cleft grafting method, from the roots of 3 ~ 4 cm high positions in the stock cut a knife, remove the rootstock seedling growing point, use the blade in the center of the main stem from top to bottom split 1.0 ~ 1.5 cm deep incision.Scion hypocotyl cutting into wedges, special shaving 1.0 ~ 1.3 cm long, about the Angle about 25 °, insert the scion root stock split mouth parts, make the rootstock and scion smooth joint, and then use grafting can be fixed.
2.5 management after grafting
(1) temperature management Eggplant grafting wound healing optimum temperature during the day 25 ~ 30 ℃, 20 ℃ at night.The lowest temperature is not lower than 18 ℃, the highest is not higher than 35 ℃.
(2) the humidity management Moisturizing and shading them in small tunnel after grafting.The roots of moist as well, 5 ~ 7 days after grafting humidity remain above 95%.Within 3 days after grafting is not water, using the scion root water supply.Leaf wilting phenomenon, such as a scion with 2 days a small amount of water.Three days later there are still wilting, increase amount of foliar spray appropriately according to the weather situation.Spray atomization as far as possible, do foliar moist and grafting place dry.Grafted plants see light not wilting after 1 week can stop the foliar spray, water moisture to the roots.
(3) light management within 1 week after grafting adopts double sun-shade net shading, adopt single sun-shade net shading after 1 week, gradually increase the illumination.Blade wilting can see light not gradually remove sun-shade net, see light smelting plants directly, enter the normal seedling management.Late increasing light smelting plants, moderate growth.
2.6 the breed standard
Miao 12 ~ 15 cm high and thick stems 0.3 ~ 0.5 cm, with 4 ~ 6 true leaf, large thick leaves, leaf color dark green, internodes short, root system full of holes at the bottom of the plate, no plant diseases and insect pests.
