Rose is a very good flowering plant. Cutting with softwood cuttings can save cutting materials. As long as there are a few mother plants, a large number of seedlings can be produced in a short period of time. At the same time, softwood cuttings have a longer duration and can be implemented from May to August. A group of seedlings can be propagated within 30 to 40 days, and 3 to 4 batches can be propagated each year. This creates favorable conditions for the balanced production of the nursery. However, the cutting of soft materials is relatively tedious, management must be meticulous, and the requirements are strict. The specific approach is as follows:
First, the preparation of cutting seedlings.
Softwood cut roses can be used horse dung (straw) hot bed or cold bed.
1. To make the bed for convenience, the size of each seedling should be as good as possible using an integer, such as width 1.5 or 2 cm, east to west, north to north, to facilitate lighting and warming. Bed height of 1.5 meters before and after the height difference of 20 or 30 cm, the bed depth to the front can be 60 cm, the bottom stone 10 cm (or not shop), horse manure 15 to 20 cm, coarse sand 15 to 20 cm, by Sand-to-glass 20 cm, four beds available for soil temperature bed or wooden frame, brick frame, and the best tiles or glass, do not stain. The hotbed covers are made of wood, the glass is installed, the window frames are painted to extend the service life, and iron handrails are installed at both ends so that the covers can be uncovered and a small bed can be made every other window frame for ventilation or watering. . Contact with the hotbed around the window sashes should be made in order to avoid the wind.
2, pony manure will be stacked to heat the horse to 50 to 60 degrees Celsius manure into the hotbed, according to 15 to 20 cm thickness pave the way, and then spray water, about 1 kilogram of water per square meter, when the hotbed with foot Wet, but not water, spread the fully heated horse dung on the upper soil layer, and lay it on the lower layer than the raw horse dung, so that it will last for a long period of time, and it can evenly heat. The top layer of rough sand is 15 cm thick (grain diameter 1-1.5 mm). If the sand is mixed with mud and humus, it must be washed and then laid into the bed. After the excrement sand was laid, the glass window was covered. After the sun had been exposed to the sun, the grass curtains were covered at night so that the temperature in the bed rose, and the cutting was repeated the next day. Second, the cutting method 1, the choice of panicle When collecting panicle, we must choose the new year of the occurrence of strong tender strips, about 8 to 15 cm long, in order to achieve the degree of semi-lignification is the most suitable. At the same time, it is necessary to pay attention to the use of the bar, do not take long branches, excessive prickles branches and flowering branches.
2, mining time in the early morning 5 to 7 harvest, quickly cutting. Do not collect the cuttings with water, do not pile too much and press too tightly. After the shoots are harvested, remove the lower 3-4 leaves. The upper 2 or 3 leaves are cut or cut in half. Then use a pair of sharp scissors to repair the cut. The degree of clipping must be mastered, and the cut point is exactly the branches. Semi-woody place (do not emphasize the same length), cut mouth should be smooth, do not make chapped.
3, cut the inserted branches into the sand 15 cm, do not be too deep, do not make the lower end of the skin when the split, for the proper use of small sticks to drill hole, and then cut, easy to root available naphthalene acetate or 2,4 - D handles the roots and immediately fills with water immediately after insertion.
Third, insert management. Immediately after spraying, spray water, cover the window sash, and block all gaps. In the first 5 days just after the cutting was completed, curtains were used to avoid sunlight. After the cutting, the temperature and humidity in the bed shall be measured every day. The seedbed after cutting shall be prevented from being ventilated. After cuttings, keep the seedlings moist, spray water no less than 4 times a day, once in the morning at 5-7 hours, once at 11-12 hours; once at 2-3 pm, once at 5-7 hours, it should be sprayed as usual in rainy weather. Spraying water can be sprayed with a fine hole sprayer or a sprayer. The amount of water does not need to be too large, as long as the dew often remains on the leaves, and the clear water basin is placed in the cutting bed to automatically adjust the humidity. The shading straws should be covered at 8 o'clock in the morning and removed at 5 o'clock in the evening. Pay attention to drainage in the rainy season and prevent rainwater from leaking into the bed to make rootlets rot. On cloudy days, the windward time can be longer. In order to increase the seedbed temperature, it is possible to use oblique sunlight for warming in the evening; the seedlings after cutting roots need more wind to make them strong. The seedbed must be kept absolutely clean so as not to rot.
Fourth, the basin transplant. After the seedlings are cut into the living plants, they can be put on the basin after about 30 days, and the seedlings are removed from the seedlings. For the first time, the transplanted roots are transplanted. Therefore, they must be carefully managed during the operation. In the small flowerpots, sufficient humus, gaza, and ash are used, or they are planted with fertile garden soil. The seedlings are planted with the plants and are immediately filled with water. Then still need to be placed in the hotbeds and properly managed (the same as in the initial insertion). After 3-5 days, the windward time was gradually prolonged, and its growth environment was similar to that of the open ground. The soil ball was then moved to the open bed. The transplant must be slightly later, that is to say, the young roots turn from white to tan so that it is black, that is, after the roots reach the degree of lignification, the roots are transplanted again to the open seedbeds. The transplants should be carried out in the evening and should be properly covered. Overcast for a day or two.
