What is the reason for the fallen leaves of Honeysuckle?

Honeysuckle, also known as honeysuckle, is widely used in our lives, and it is planted all over the country. Before, many honeysuckle growers consulted on the Internet, saying that the honeysuckle had abnormal defoliation. Why? Is honeysuckle sick or something. The editor specially analyzed this problem and sorted out the data. If necessary, you can read the following content carefully.

1. Soil discomfort

Honeysuckle planting appears the phenomenon of falling leaves, the first thing we have to consider is the problem of planting soil. Although honeysuckle has strong adaptability, it does not mean that all soils are suitable for planting honeysuckle. If the soil is not suitable, it will also cause honeysuckle to fall leaves. Secondly, there is no problem with the planting land, but the later soil loosening, soil cultivation and other work has not been done, resulting in changes in soil structure, which will also lead to honeysuckle defoliation. If it is caused by soil problems, then we need to change the land for planting or disinfect the soil before planting.

2. Improper management of water and fertilizer

Improper management of water and fertilizer is mainly manifested in four aspects: water yellow, dry yellow, fat yellow and hungry yellow. Water yellow is caused by too much watering; dry yellow is caused by lack of water or lack of timely watering; fat yellow is caused by excessive fertilization, too often, too vigorously, or improper types of fertilization; hungry yellow is caused by lack of nutrients, but there is no timely topdressing, resulting in poor growth and development. Then what we need to do is to apply fertilizer scientifically according to the fertilizer characteristics of Flos Lonicerae, and make rational use of nitrogen fertilizer, phosphate fertilizer, potash fertilizer, micro-fertilizer, foliar fertilizer, organic fertilizer and farm fertilizer. It is best to water once after each fertilization to dilute the concentration and promote nutrient absorption. Watering actively in the high temperature and dry season and timely drainage in the rainy season.

3. Disease and pest control is not in place.

Of course, Xinxiang, where honeysuckle has unusually fallen leaves, is also likely to be caused by diseases and insect pests. The diseases that cause leaf defoliation are generally powdery mildew, brown spot and root rot. The frequent occurrence period of powdery mildew and brown spot is about August every year, so what we need to do is to strengthen field management, adjust branches and leaves reasonably and maintain plant permeability. Secondly, pharmaceutical prevention can be carried out in June, 3000 times of Syngenta's love seedling solution can be used for prevention, and strychnine can be used for prevention and control after the onset of the disease. Root rot can be controlled by mixed fungicides and insecticides. The pests that cause the fallen leaves of honeysuckle are generally underground pests, such as grubs, ground tigers, etc., so we can use methyl isosalidophos granules for poisoning.

4. Lighting conditions

The abnormal defoliation of honeysuckle may also be caused by light. Honeysuckle is a kind of light-loving plant, the demand for light is large, if the light is not enough, then honeysuckle can not carry out normal photosynthesis, so there will be the phenomenon of leaf fall. Then when this situation occurs, we need to strengthen the light of honeysuckle and reasonably adjust the sunlight of the planting place, so that honeysuckle can carry out photosynthesis normally, or change the planting site to promote the growth of honeysuckle plants.

In general, when honeysuckle has abnormal defoliation, it is basically caused by these reasons. Of course, do not rule out special circumstances, if you encounter abnormal leaves using the above methods can not be solved, you can also consult us.
