1. Strengthen pruning and shaping. Flowers and trees grow at a certain height in time to pick up the heart, adopting branching angles and twisting, twisting branches shaping, inhibiting the top growth advantage, shortening the vegetative growth cycle, and promoting flowering results.
2. Chemical regulation. Chemical synthesis of growth inhibitors promote dwarfing. When the seedlings are transplanted onto the pots, a certain amount of paclobutrazol is mixed in the culture soil. Spraying or pouring 0.15% to 0.25% paclobutrazol in the growing season or using growth inhibitors such as Chlormequat and B9 can inhibit the cells. Elongation and growth, promote cell division and thick growth, to achieve a fat leaf Zhi Zhuang, dwarfing the crown compact, multi-flowering purposes, improve the ornamental value.
3. Use dwarfed varieties. The characteristics of dwarfing varieties include strong multi-branch buds, low branches, large branching angles, short internodes, and compact plants. The main root is not obvious, the lateral roots are developed, and the fibrous roots are more.
4. Dwarf and strong seedlings. The use of nutritious seedlings will limit the development of major roots and promote the development of scallop roots, and accordingly inhibit the growth of stems and leaves on the ground.
5. Prepare culture soil. Cultured soil is the basis for potted flowers to predict plants, requiring rich organic matter, good granule structure, loose fertility and complete nutrition. It is made up of a mixture of humus, garden soil, pond mud, peat soil, river sand, organic fertilizer, phosphate fertilizer, bone powder, and grass ash. pH from slightly acidic to slightly alkaline, specifically rooted in different flower varieties to adjust the adaptability of pH.
6. Broken radicles above the basin. The seedlings were planted in pots, and the radicles (main roots) were cut short. When transplanting, the lateral roots were spread around and layered and filled. Such as chrysanthemum pots, began to add only two-thirds of the culture soil, with the growth of the plant, gradually soil, buried a few old leaves at the base, to promote the thickening of the base, grow coarse leaves in the near basin mouth, plant dwarf .
7. Change pots, fertilizer control, water system. Potted flowers are mainly based on nutrient-based soil-based fertilizers. Therefore, the soil must be constantly renewed by changing pots. Usually, the pots are changed 1 year to 2 years. According to the growth of the plants, pots are replaced by large pots and old soil is replaced with new soil. In combination with basin replacement, rooting and pruning, improving the recommended tree structure, and promoting dwarfism. Control nitrogenous fertilizers, increase phosphorus and potash fertilizers, and avoid excessive waterlogging, so as to prevent leggy and dead roots. Especially during the peak of growth period, it is necessary to make water-control fertilizer, so that the potted soil sees dry and wet, water-saving and fat-reducing, and promotes stable growth, reaching more branches, forming more flowers, shorter section and shorter branches, and dwarfing plants.
