Rose rapid seedling technology
Pingyin is the hometown of roses. In recent years, after continuous exploration and practice, a set of rapid rose seedling techniques has been concluded. The new seedling raising technique is characterized by: short seedling raising period, and generally about one year of nursery stock time, it will be able to cultivate the high-quality seedlings needed for production and cultivation, which will greatly shorten the seedling raising time. The new nursery technology can be divided into the following steps. First, Grafting 1. One-by-one grafting method In mid-September, we chose to grow robust branches of the year in the Rosewood Garden, grafting a rose bud every 20 centimeters, and checking for survival. Grafting survival buds to grow 15 to 20 cm spikes, the distance from the wall to buds 3 to 5 cm, the next wall cut into a slant. Each bundle of 20 bundles is embedded in wet wood chips with a moisture content of 60%. With the use of a geothermal heating, the temperature was controlled at 24 to 26°C and all callus was generated after 10 days. But to control it well, you can't take root. 2. The winter indoor grafting method utilizes the collected rose cuttings or direct access from the field. Scion to take annual rose branches, cut into 5 to 6 cm long, the interface cut surface to retain 1 to 2 buds. The use of "double tongue" grafting method, that is, in early December of the year to the end of January can be carried out, the rootstock and scion below the increase of 2.0 to 2.5 cm material surface, in the middle of the two spikes longitudinal cut a knife, 0.4-0.5 cm deep, cut parallel to the noodles, avoid vertical cuts. When cutting, the knife should be fast, and it is best to complete it once. The cutting surface is smooth and smooth. It should avoid repeated cutting friction, damage the formation of layer cells, and affect the formation of callus. When the two spikes are combined, the layers will be aligned. If the two ears are different in thickness, one side is aligned to form a layer. Tightly tied with plastic film, thinly tied to facilitate the production of callus, the top speed in the paraffin wax cap, paraffin temperature 60 ~ 80 °C. The bundles of grafted cuttings were bundled and the wet wood chips gave birth to the callus and used for sand reserve. Second, sand reservoirs where the leewards are sunny and not watery, dig one meter deep and one wide, and measure the length of the cuttings in order to determine the length of the cut. Put a good bundle of cuttings into the ditch, and set up the ditch in the diagonally downward direction, and then Cover a layer of 3 to 5 centimeters of fine sand and pour a suitable amount of water. Note that as the temperature rises and falls, the territories are reduced or thickened in a timely manner to ensure that the cuttings do not freeze and germinate. If the length of the ditch is 3 to 5 centimeters, a straw should be placed and the diameter of the grass should be 15 to 20 centimeters so that the cuttings can be ventilated and ventilated. After the cut, the cuttings will be moved to the seedbed first, and warm and moisturizing measures will be taken. After rooting, the cuttings will be moved to the nursery. Third, the nursery 1. Nursery seedlings Law in late February after the thawing up the bed, will be a dragon or grafting in winter indoor grafting, according to the spacing of 15 cm and 30 cm buried in trenches, irrigating the water, and then cover the plastic for the shed. In late April, the seedlings were gradually uncovered. Timely unbundling, wiping buds, strengthen management, after the fall out of the garden into seedlings, seedling height can be more than 50 cm. 2. The Daejeon seedling raising method will be carried out when the temperature is relatively stable in late March. It will control the spacing of 15 cm and 30 cm to plant the cuttings, effectively strengthen the field management after planting, and can grow into seedlings in the autumn. They are all above 40 cm. . 3. The nutrition cup seedling cup is made of newspaper or plastic film, the length is generally about 3/4 of the cuttings, the diameter is about 10-15 cm, and there are 4 to 6 corn-sized vent holes, evenly distributed in nutrition. The lower half of the cup. Put the inserted cutting into the cup, fill in the soil in the nursery bed, densely squeezed in the seedbed, and irrigate the water, but pay attention to antifreeze. 500 can be discharged per square meter. In the spring, they are moved to a field or a shed to raise seedlings with a spacing of 10 cm and 30 cm. 4. The method of raising seedlings in the north-south direction is to open each ditch with a depth of 1 meter, and the length is determined by the number of cuttings. Put the cuttings in a row of 20 pieces and put them into the bottom of the ditch. Then cover the fine sand 5 to 10 centimeters, pour the appropriate amount of water, and seal the ditch with straw and plastic film to keep it warm and cold. After the cuttings promote the callus rooting, they will be moved to the nursery in spring. 5. Winter-winter-style greenhouse nursery method Grafting the grafted autumn wolfberry or one-draft grafting has been prompted by the root-generating cuttings, before mid-October moved to winter-style greenhouses, planting spacing 15 cm 30 cm After the irrigating, mulching water, covering the mulch to improve the wetlands, moisture insulation through the shed, cut the anvil to wipe buds, weeding and fertilization, prevention and treatment of diseases and insect pests, before the nursery and other management measures. In the coming spring, the nursery will grow into seedlings. The height of seedlings is generally more than 40 cm.
