Eggplant Grafting and Seedling Technology

<

First, grafting method 1. Connection method. Rootstocks of Torubamba, Japan are seeded 25–35 days ahead of time (25 days ahead of sowing after germination, 35 days ahead of live broadcast); Japanese wild red solanum and Congo wild tomato seeded 10 days in advance; South Korean CRP sowed after sowing 20 Days, 25 days in advance of non-germinating live broadcast; Korea CYP and Anyang ArQ as root stocks 3-5 days in advance. When the rootstock grows to 6-8 true leaves and the scion grows to 5-6 true leaves, the stem is semi-lignified and the stem diameter is 0.3-0.5 cm, which is most suitable for grafting. The rootstock leaves two large, robust and true leaves, cut flat from the second true leaf 3-5 cm above the ground, removing all other leaves from the top, and then slitting with a blade. In the middle of the stems of the rootstock, cut 0.8 to 1 cm thick vertically, then remove the scion from the semi-lignified part, usually cut off the cotyledon and 2 true leaves on it, and keep the top 2-4 true leaves; cut the stems. Into a wedge, the size of the wedge is equivalent to that of the rootstock (wedge length 0.6-0.8 cm); the scion is then inserted into the incision of the rootstock, aligned with a narrow strip of plastic or clipped with a grafting clip, and then placed into a grafted seedbed. 2. By connection method. The scion is sown five to six days ahead of the rootstock, and the rootstock and scions are 2-3 when the leaves are long. Choose two seedlings with similar rootstocks and scions. The rootstocks and scions are chamfered with a blade 1 cm below the first true leaf. The incision is 0.4-0.5 cm long and the stem is half as deep; the scions are cut upwards and the rootstock is cut downwards. , Then connect the scion and rootstock to the good incision, fix it with grafting clip and transplant it into the grafted seedbed. The rootstock of the rootstock and scion should be separated to facilitate the cutting of the roots after survival. Second, grafted seedlings management of eggplant grafted seedling survival is the most critical factor is the temperature and relative humidity of the air. Winter and spring pod eggplant grafting when the (late September to early October), due to the cold weather, should be set in the winter warm plastic greenhouse electric hotbed or seedling bed buckle small shed, further insulation moisturizing. The autumn and winter pods and wintering pod eggplant cultivate the grafted seedlings in midsummer and early autumn, and the grafted seedbeds and plastic sheds are shaded, protected from rain, moisturized, ventilated and tempered in the greenhouse. Grafting seedlings should be planted along with planting small arches. When planting, plant the seedlings into the seedbed by 10 cm square, and immediately water it (do not allow the water to soak the interface); after the water infiltration, cover the soil (the buried soil shall not be buried, and the grafting clamp shall be exposed on the ground). After the whole planting, the small arch shed is put on, and the plastic film is sheltered from the rain (Summer and Autumn) or covered with insulation (in winter). Three days after grafting, the temperature in the small arch shelter was maintained at 25°C-30°C during the day and the air relative humidity was over 95%. From 10:00 am to 3:00 pm, appropriate shade, 3 days after the beginning of ventilation, and gradually see the light; 5-7 days after the grafted seedlings survived; scion 10 days after the root. Grafting seedlings were planted in 35-45 days in a warm plastic greenhouse. (Wenchang Street Office, Changqing District, Jinan City, Zip Code: 250000)
