Rapid Yang Yangmiao Technology
First, collect cuttings, scion. 1. Time: The time for collecting cuttings and scion is generally carried out after the late autumn leaves and before the beginning of spring in the following year. 2, varieties: cuttings can be collected in Beijing Yang, Canada, Yang and other strong resistance varieties, while the scion can be collected triploid Chinese white Poplar or 107 such as fast-growing Yang variety. 3, standard: cuttings to choose the thick and full of annual branches, cut into 20 to 25 cm long spare. To use scion, one should also select one-year-old full-grown shoots. Second, grafting technology. 1. Grafting time: The grafting time of the nursery method should be carried out during the dormancy period of the tree. 2. Grafting method: The method of bud grafting is introduced. The specific operations are as follows: (1) Cutting buds. The left hand holds the fast-growing Yang scion, and the right hand grips the knife about 1.5 centimeters from the top of the shoot with a wooden flat cutting knife, then cuts the bud under the bud at a 45-degree angle under the head and puts it into the apparatus filled with clean water. (2) grafted buds. Cutting a plane 2 centimeters above the cuttings requires a similar plane to the splicing buds, and requires a 45-degree angle bevel to cut a plane that matches the bud-shooting cuts. Then remove the buds from the water and insert them into the joints of the cuttings. Third, then deal with. Because this method of grafting is carried out during the dormant period of the tree, a fast-growing poplar needs to be treated as a sand trap: a pot of 1 meter in height, 80 centimeters in width, and of unlimited length. First lay a layer of 10cm thick wet sand on the bottom of the pool, put a layer of fast-moving cuttings, then spread a layer of sand and put a layer of fast-growing poplar. Followed by analogy, then cover with thick plastic cloth. Fourth, nursery technology. 1. Cutting time: Cutting is generally performed before and after “Changmingâ€. 2. Cutting technology: It is required to insert fertilizing, ploughing and leveling before plugging in, and to achieve the standard of Panasonic solid and wet and dry, it can be cut. The cutting spacing should be 1 meter and the spacing between the rows is 33 centimeters. The key to cutting technology is to insert obliquely and expose buds, which is appropriate to the ground. 3. Post-insertion management: In order to prevent the young leaves from being harmed by phytotoxicity, one can manually capture the beetle. On the other hand, it can spray 50% of dichlorvos EC 800 times, which can reduce the damage. In addition, weeding and weed removal should be repeated during this period in order to facilitate normal germination of poplar buds. 4, timely unbundling: When the fast-growing Yangzhi grow to 20 cm high, you can use a knife to draw a knife behind the budding solution.
