First, the production point straight insertion method: use black seed pumpkin as a rootstock, choose a strong affinity, good quality, more resistant to the local varieties of the scion. The anvil and ear seeds need to be disinfected and germinated before sowing. When winter and spring sorghum are grafted, black seed squash should be sown for 2 to 3 days (with temperature control seedlings). The second leaf of the rootstock seedlings is spit buds, and the first true leaf of the seedlings is 1 cm in diameter, which is the best grafting period. The growth point of the rootstock was cut with a razor blade, and then bamboo needles (self-made, and the stalks of the scion) were inserted vertically from the incision 4 to 5 mm. The scion was cut at an angle of 30° from the hypocotyls at a distance of 5 mm below the cotyledonary node, and was an elliptical-shaped section of 4 to 5 mm in length. Then remove the bamboo needle, insert the scion with the cotyledon into the pinhole, make the scion match the rootstock and fix it with a plastic clip. After spraying the water, put it in a moisturizing small arch shed. 95% humidity is maintained within 3 days after the connection, the daytime temperature is 25-28 °C, and the nighttime is 18-20 °C. Small ventilation after 4 days, after 8 days, the film can be peeled and smelted. About 25 days into the three-leaf one heart period can be colonized. Linyi Fertilizer Network Copyright

Second, the connection method: the rootstock in the nutrient bowl, on the hypocotyl of the ion leaf section 5 to 10 mm, obliquely cut from the top to the mouth of 6 to 10 mm, 20 to 30 mm under the coniferous cotyledonary node The mouth is cut obliquely 6 to 8 mm (without cutting the seedling and the root is to be taken), then the tongue-shaped tongue wedge is inserted into the incision of the rootstock, the interface is fixed with a micro-plastic clip, and the root of the scion is buried with the soil. The base of the scion was cut off in about 20 days, and other managements were basically the same as the straight insertion method. Linyi Fertilizer Network Copyright

ASA Copolymer for Extusion Super Cover
ASA resin is a ternary copolymer consisted of Acrylonitrile, Styrene and Acrylate. ASA copolymer integrates acrylates's high impact strength and excellent weather-resistance, chemical resistance and high hardness of acrylonitrile, good processability of styrene. It can be extruded single & coextruded over ABS and PVC. ASA is particularly used in outdoor applications that require long term color stability, excellent weather resistance.
