Potted osmanthus trees fertilize potted osmanthus trees Due to limited potash soil and insufficient nutrients, it is difficult to meet the long-term need for growth and development of osmanthus trees. Therefore, it is necessary to continuously replenish fertilizers. Otherwise, the plants are thin, the growth of new shoots is poor, the flower buds are few, the flowering is thin, and even flowering is impossible, which seriously affects the ornamental effect. Potted osmanthus trees sprouted in the middle and early March of buds, and soon entered a period of new shoot growth. To this end, it is necessary to apply 1 to 2 fast-acting nitrogen fertilizers before and after germination, so that the growth of new shoots is stout and full, which lays a foundation for flower bud differentiation.
Friends who like to cultivate flowers all know that the saying goes, "Third and seven branches." Water and fertilizer management is a regular and important work.
1. Control moisture in different growth periods
Watering osmanthus in different growth periods, the demand for water is different, watering too much or insufficient, have a direct impact on the normal growth and development of plants. Newly planted sweet-scented osmanthus trees, especially within one month after planting, should be watered in a timely manner according to weather conditions and site conditions. Each watering must be thoroughly irrigated. Conditionally, the crown of the plant should be sprayed with water in order to maintain a certain degree of air humidity and reduce the evaporation of water from the seedlings. In addition, in order to promote early flowering of sweet-scented osmanthus, in mid-September, when flower buds begin to sprout, they should be watered in an appropriate amount to keep the soil moist. Before watering, Zhu should loosen the soil and then perform watering operations. When using a water pump or tap water, do not wash away the mud from the root of the osmanthus plant. Adult sweet-scented osmanthus has a certain drought-resistance capacity, does not require a lot of watering, and it only has to be drought-proof and watering when it is hot and early.
2, it is best to work to prevent drowning
Flood prevention Osmanthus intolerance waterlogging, poor ground drainage or high groundwater level, will cause large loss of leaves, root rot or even death. After the rainy season and after a long period of rain and heavy rain, we must promptly check and do a good job of trenching and draining to ensure the normal growth of osmanthus saplings. Practices over the years have shown that, in low-lying areas where drainage is not smooth, osmanthus growth is poor, affecting the flowering of osmanthus, black root rot, and severe yellowish tip. These phenomena are due to drowning hazards.
3, young sweet-scented osmanthus and adult osmanthus fertilizer
In Zuoyi's "Mirror", osmanthus "when the pig's cricket was cast, the pig's quail was made of silkworm and the second silkworm was the manure". This shows that fertilization is important for the growth and development of osmanthus. In order to make osmanthus flourish and grow vigorously, fertilize it. . Fertilization should be applied to thin fertilizers, and mainly available nitrogen fertilizers. Young osmanthus trees need to be fertilized four times a year, before the winter, early spring, early May, late June and late June until the end of July. Choose sunny weather and dry soil. The first two times were dominated by cattle and sheep manure and lake mud as base fertilizers, and the latter two were mainly fast-acting nitrogen fertilizers. The sweet-scented osmanthus is fertilized three times a year. One of the basal fertilizers was planted in the middle and late October to the winter before the winter. The fertilizer was used twice for the first time. The first time it was used as a tipping fertilizer. It was applied in February and March to promote the spring shoots, and the second time to stimulate the flower fertilizers. In August (1 month before flowering), people were employed to increase the amount of flowers and improve the quality of flowers.
At the same time, since the sweet-scented osmanthus seedlings absorb nutrients and moisture in the fibrous roots around the crown, it is advisable to fertilize the outer circle of the canopy projection, and the depth of the ditches can be determined by the depth of the root. Newly transplanted sweet-scented osmanthus, due to the damage of the root system, has weak absorption capacity, and therefore fertilizer should not be too early. When fertilizing, the fertilizer should not come in contact with the foliage, nor should it be in direct contact with the roots and fibrous roots. After the application, it is required to cover the soil with the meal and at the same time level the floor.
When fertilizing Osmanthus fragrans trees, pay attention to the following four taboos. A bogey of hot fertilizer, potted osmanthus tree fertilization summer fertilizer should not be selected around noon or noon, because at this time the basin of high soil temperature, dressing easily burn the root system, it is best to fertilize in the evening, and then watering. Second bogey concentrated fertilizer, potted osmanthus trees fertilization can not be too concentrated or too much application, should master the principle of thin fertilizer, generally with seven minutes of water, three points fertilizer or fertilizer is more appropriate. 3. Avoid bogey and apply fertilizer without composting. Fermentation inside the pot will produce high temperatures and it will easily cause root damage. Four avoid sitting fertilizer, potted osmanthus trees when the basin can be enough base fertilizer, but to add a layer of soil above the fertilizer, or the fertilizer buried in the pelvic and pot edge soil, the naked roots is strictly prohibited directly into the fertilizer.
