仙客来属于易染病花卉,其病害不外乎两种:侵染性病害和非侵染性病害。防治要掌握防患于未然、综合防治的原则。非侵染性病害的防治此类病害的发生主要是由营养元素失调、温湿度不适、水分失调及有毒物质侵染等因素造成,它不仅直接影响仙客来的生长,同时也削弱了植株对病原物的抵抗力,为某些病菌的侵入创造了有利条件,这样也容易诱发侵染性病害。若为仙客来提供良好的生长条件,使其健壮生长,并增强自身对病菌的抵抗力,不仅能避免非侵染性病害的发生,也能有效地预防侵染性病害的发生。 1.合理调配使用营养元素氮、磷、钾三种元素配比不合理及微量元素缺乏或过剩会使仙客来生长不良,呈现病态,减弱植株对病原物的抵抗力,造成病害。缺氮时,植株生长受阻,表现为矮小,叶
Cyclamen are susceptible to blossoming flowers, its disease is nothing more than two: infectious diseases and non-invasive diseases. Prevention and control should take preventive measures, the principle of comprehensive prevention and treatment. Prevention and treatment of non-infectious diseases The occurrence of such diseases is mainly caused by factors such as nutrient imbalance, temperature and humidity discomfort, water imbalance and toxic material infection. It not only directly affects the growth of cyclamen, but also weakens the plant-to-plant Pathogen resistance, for some bacteria invaded create favorable conditions, it is also easy to induce infectious diseases. If cyclamen to provide good growth conditions to make it robust growth and enhance their resistance to bacteria, not only to avoid the occurrence of non-invasive diseases, but also effectively prevent the occurrence of infectious diseases. 1. Reasonable deployment of nutrients using nitrogen, phosphorus and potassium three elements of unreasonable ratio and the lack of trace elements or excess cyclamen will make bad growth, showing pathological, weakened plant resistance to pathogens, causing disease. Nitrogen deficiency, plant growth retardation, showed short, leaf
