On the Cultivation of Guihua Village

Potted osmanthus, in late autumn to early spring, when the pot soil is slightly dry or the leaves are a little wilting, water it once and for all. In the prosperous season of late spring and early autumn, watering is more frequent. If you have no experience, the most mechanical way is not to do it (wither) or water it, but to water it thoroughly. When there is too much water, the leaves turn yellow.

How to apply fertilizer after the spring? Fertilization should be started when the temperature rises above 15℃ at night. At this time, branches begin to grow and need fertilization. Drill four small holes around the pot soil, evenly put down the compound fertilizer, and then cover it with soil. Stop fertilizing as soon as the buds grow out. Overnutrition will cause buds to fall off (except Sijigui). Spraying flowers and makeup can make buds strong, petals plump, colorful and fragrant.

The principle of ventilation is that natural air circulation can increase the air humidity around potted flowers, increase the content of carbon dioxide around leaves, and recycle the air around leaves with germs, which is the same as "running water does not rot", making potted flowers not easy to get sick.

How to prune before the temperature rises above 15℃ in spring, and use household scissors or sharp blades to cut off dead branches, twigs and branches with pests and diseases, so as to make way for new branches and not give opportunities for pests and diseases to propagate (pay attention to coating anti-corrosion film on the pruning mouth to promote wound healing).

Pest control If pests are found, household spray insecticides can be used; When diseases are found, the diseased leaves or branches are directly cut off.

Osmanthus fragrans likes warmth, strong resistance, high temperature resistance and cold resistance. Osmanthus fragrans prefers sunshine. In full light, its branches and leaves are lush and flowers are dense. In the shade, its branches and leaves are sparse and flowers are scarce. If potted indoors in the north, it is especially necessary to pay attention to sufficient light to facilitate growth and flower bud formation. Osmanthus fragrans is relatively humid, and it is forbidden to accumulate water, but it also has certain drought resistance. Osmanthus fragrans is not strict with the soil. Except alkaline soil and low-lying land or soil that is too sticky and poorly drained, it can generally grow, but slightly acidic sandy loam with deep soil layer, loose and fertile soil and good drainage is the most suitable.

(1) intertillage weeding. Tree tray with trunk as the center and diameter of 1 m, with emphasis on loosening soil and weeding. After irrigation or rainfall, intertillage and loosen the soil to prevent the soil from hardening.

(2) Water and drainage. Osmanthus fragrans is mainly watered within one month after new planting and in the summer of the same year. Newly planted osmanthus fragrans must be watered and permeable, and the canopy of the plant should be sprayed with water conditionally to maintain a certain air humidity. Osmanthus fragrans is not tolerant to waterlogging, so timely drainage or transplanting waterlogged plants, combined with certain sand planting, can promote the growth of new roots.

(3) Promoting flower and keeping fruit: Spraying the solution of "Promoting Flower King No.3" in the growing period can inhibit the overgrowth of main shoots, redundant buds and lateral centers of various crops and promote flower bud differentiation. Spraying Zhuangguodiling solution once before flowering, young fruit stage and fruit expansion stage can thicken fruit pedicels and improve nutrient transport. Prevent falling flowers, falling fruit, cracking fruit, hard fruit and deformed fruit, and make the fruit beautiful in color, shape and taste.

(4) Rational fertilization. Fertilization should be based on the principle of thin fertilizer and diligent application, with quick-acting nitrogen fertilizer as the main fertilizer, and medium and large seedlings should be fertilized three or four times a year. In early spring, apply organic fertilizer to the tree tray to promote the growth of spring shoots. Inorganic fertilizer or garbage miscellaneous fertilizer should be applied in early winter. In the meantime, fertilization can be applied once or twice according to the growth of osmanthus fragrans. Newly transplanted osmanthus fragrans should not be topdressed too early. The base fertilizer of the transplanting pit should be mixed with soil before covering it. Spraying new high-fat film liquid can prevent bacteria from invading, improve the absorption and utilization rate of fertilizer and reduce the dosage of fertilizer.
