Pruning plays a very important role in the breeding of flower seedlings. The “seven-point, three-point shear†often used is an important cultivation experience. Through pruning, the branches of flowers and seedlings can be distributed evenly, and nutrients can be saved, consumption can be reduced, the tree vigor can be adjusted, and leggy can be controlled, so that the flowers and trees can be neatly shaped, graceful, and achieve multiple purposes of flowering and multiple fruits. Flowers and trees can be trimmed throughout the year, but mainly in winter and summer. Summer pruning is mainly in the growth period, and the time range starts from the spring sprouting shoot and stops until the end of the autumn. During this period, only partial, mild pruning can be done, and withered or broken branches can be trimmed to maintain the neat and graceful shape of the plant. Winter pruning refers to the pruning of the dormant period. The time range starts from the growth of the late autumn shoots and ends before the buds sprout in the early spring. The pruning is heavy during this period, and the focus of the pruning is on thinning and short cutting according to the growth characteristics of different kinds of flowers and trees. When pruning, it depends on the species and treats it differently.
1. Flowers and trees that bloom in the spring, such as plum, peach, forsythia, spring, clove, jellyfish, redbud, etc., flower buds are formed on the branches of the previous year. Therefore, winter can not be re-cut, can only cut off the autumn shoots without flower buds. If the pruning is too heavy during the winter, the buds that have formed in the summer will be cut off, affecting the flowering in the second year. The correct course of action is to carry out short cuts within one to two weeks after flowering to promote the sprouting of collaterals into new shoots to form flowering branches in the coming year.
2. All the flowers that bloom on the branches of the year, such as rose, hibiscus, jasmine, poinsettia, tuberose, crape myrtle, kumquat, bergamot, hibiscus, etc., should be cut in winter to promote the growth of new shoots and flowers in the following year. Many results.
3. For the foliage plants, the time for pruning should be determined based on the winter room temperature. If the room temperature is low, it should be trimmed before entering the room in order to reduce the crown width and reduce the floor area; if the room temperature is higher, it should be out of the room in the coming year. Trim, so as not to stimulate sprouting buds in the winter to shoot new shoots, consume nutrients.
4. For flowers that have weak germination power, such as conifers, they are difficult to recover after heavy cutting.
5. Vine flowers and trees do not generally need to be trimmed, and only the old and dense branches can be cut off.
6. Magnolia, cherry blossoms, chicken claws and other tree-like flowers and trees, but also do not do a large trim. Pruning is mainly for thinning and short cutting. The thinning is the cutting of dense branches, cross branches, leggy branches, delicate branches, diseased branches and dead branches, in order to facilitate ventilation and light transmission, reducing the occurrence of pests and diseases. The short cut is to shorten the part of the shoot, promote its sprouting lateral branches, adjust the growth, make the canopy evenly distributed, beautiful tree shape, is conducive to more flowering and more results. When trimming, the cut should be smooth and the cut should be about 1 cm above the lateral bud. If the clippings are too close to the lateral buds, the stem and leaf original body in the buds will often be damaged, and the buds will also be easy to air dry; if the clips are too far from the lateral buds, the residual piles will be left, which will affect the appearance. When pruning, it should also be noted that the top lateral buds should remain on the outside of the shoots, allowing the new shoots to grow outwards, which can make the tree beautiful. It can be seen that the pruning of seedlings is also a great knowledge. Miao farmers can properly trim their seedlings according to their own characteristics and their own needs.
