First, choose the fine strip parent and the plug as the mother of the strip, require good varieties, growth and prosperity, no pest damage and other conditions, growth and aging plants are not selected as the parent strip mining. On the same plant, the middle and upper parts of the cuttings should be selected, and the branches should be filled with the sun, and the internodes should be short, the buds should be full, and the branches and leaves should be thick. On the same branch, the middle and lower parts of the branches are selected for the hard branches, because the middle and lower parts store more nutrients and the tip tissues are often not full, but the tree-shaped coniferous trees such as Cypress, Cedar, etc. The tip is good, after the cut trunks grow straight, beautiful shape, with cuttings, cut to the top of the delicate, and chrysanthemum, etc. in the cutting, the use of the tender head.
Second, the correct cutting treatment Cuttings should be carried out immediately after cutting the cuttings, especially leaf plugs, so as not to wilt the leaves, affect rooting. At the end of the fall, cuts such as rose, hibiscus, and lycopene cannot be inserted immediately. They can be cut and tied, bundled with moist sand in pots, and maintained indoors at a temperature of 0- At 5 degrees, in the winter, do not make the sand too dry, and wait for the next spring to cut it again. For rose flowers and other flowers can also be cut in plastic sheds in winter. Cactus succulent plant cuttings, after clipping should be placed in a well-ventilated place to dry for about a week, until the cut-out at the time of slightly shrinkage and then cutting, or easily rot. Begonia, oleander, etc., can be soaked in clean water after cutting, and the roots can be directly planted into the pot. Rose, Milan, etc., can cut the bottom of the cuttings in the vitamin B injection, take out for a minute or two so that the liquid is sucked into the cuttings and then inserted into the coarse sand, so that the treatment has the effect of promoting rooting. The cuttings of flower plants with more moisture content, such as Hydrangea, Begonia, etc., cut some grass ash under the cuttings to prevent rot after cutting.
Third, the selection of a suitable cutting matrix In addition to water, the cuttings have to be inserted into a certain matrix, a variety of types of substrates, garden soil, culture soil, yellow mud, orchid mud, ash, gangue, river sand, etc. Their environmental requirements are: good water permeability, a certain degree of water retention, easy temperature rise, and good heat preservation. For the more extensive flowers, generally inserted into the garden soil or culture soil, the flowers of hi-acid soil can be inserted into the yellow mud or orchid mud, and the hard-to-root flowers and trees should be inserted in the ash, gangue or river sand.
Fourth, do a good job in the management of cuttings After cutting and cutting, strengthen the management and create a good rooting condition for cuttings. Generally, the cuttings of flowers need to be rooted to be moist and air-flowing. The glass or plastic film can be placed on a pot or a bowl. Made of a hood to maintain temperature and humidity. A small brick is placed on the underside of the cover to allow air to flow in. In the summer and early autumn, the cutting pots should be placed in the shade during the day and in the open air in the evening. In early spring and late autumn and winter when the temperature is not enough, they can be placed in a warm place or in a greenhouse. Must pay attention to the adjustment of temperature and humidity. Afterwards, according to the speed of the cuttings, the lighting will be gradually strengthened.
