Persimmon Grafting Time and Method
1, anvil buds After the grafting, as the temperature gradually rises, the tea tree gradually sprouts or germinates, often sprouting from the base of the rootstock or below the interface, and must be erased in a timely and repeated manner to ensure the rapid healing of the scion and germination to increase the survival rate. . In the process of wiping buds, when grafted uncultured plants are encountered, 2 to 3 germinating anvil shoots are selected for preparation for the next year. 2, film, film When the scion and rootstock fully healed and germinate new shoots as high as 15 to 20cm, filming and filming should be performed in time. The time has entered 6 to 8 months. At this point, choose the side without scion, use a grafting knife to draw a knife down from the upper slash, depth to cut the film without injuring the rootstock, and withdraw all the coated membranes for centralized treatment. Membrane, film depends on the growth of the scion seedlings, filming, filming prematurely, is not conducive to the healing of scions and rootstocks; filming, filming too late, but also limiting the growth of the base of the scion, easy to form " "Slim waist gourd" shape, in case of strong wind will make the scion scion along the base stem, resulting in graft failure. Therefore, the solution is the final key to the success of grafting transformation. The complete withdrawal of the Zha Membrane means that the grafting transformation is completed. 3, weeding, weeding, fertilizer, pest control (1) Weeding and weeding After the tea tree is grafted and the rainy season is approaching, it is in the dry season. The growth of weeds is relatively slow, and weeding and weeding should take place due to time and place. For plots with less weeds, cultivator weeding may be unnecessary before the rainy season; for plots with more weeds, 1-2 plowing weeds can be performed depending on the situation. (2) Dressing Topdressing is in principle carried out in conjunction with cultivating and weeding. However, in the dry season, top-dressing is generally not adopted. It is only after the arrival of the rainy season that the seedlings will grow and grow. The reason is that the pre-grafting tea plantation has been applied basal fertilizer, do not have to top-dressing in the whole garden, only for weaker growing plants, take the morning and evening of sunny days to apply 0.2% to 0.3% urea in the root top dressing or root leaves. 4. Pest control After grafting, the survival of the tea plant is generally very rare. Even if it occurs, the disease should be treated with the disease. The focus of prevention and control during this period should be to prevent or control the occurrence and change of pests. Prevention and control measures should follow the “prevention-oriented, comprehensive prevention and control†agricultural policy, and vigorously promote the green prevention and control technology, take the cutting yellow board 70 pieces, blue board 30 pieces/667?, or 2 000 to 3333.33h? Install a killing Insect lamps, etc., take chemical agents when necessary. 5, topping Peng Peng For grafting survival growth branches, to withdraw the film, if it is to be reserved for the next year's development, the main branch can be used for the first time after the top shoot is harvested; if it does not function, the conventional management will be adopted. At the end of the tea season, a light topping is applied to preserve the lateral branches. In the second year, the inspection and seedling supplementation will be carried out again, until there is no shortage of plants in the tea plantation and the original variety may be mixed.
