夏季的仙客来易感病,线虫便是罪魁之一。它主要危害仙客来的根系,当根系受到危害时,根上常常有许多瘤状物,线虫即在瘤内存活,人们也因此称之为根瘤线虫或根结线虫等。导致线虫快速孳生的两个必备条件,为温度高和湿度大。如果人为地限制其中一个条件,线虫就难以孳生了。线虫生长最适宜的土壤温度是15～25℃,而仙客来生长时期应达到8～15℃,其中生长最适宜的温度在15～20℃,两者几乎在相近的温度下同步成长,因此利用控制
Summer cyclamen susceptible, nematode is one of the culprits. It is mainly harmful to the root system of cyclamen. When the root system is harmed, there are often many nodules on the root. The nematode survives in the nodules and people call it root-knot nematode or root-knot nematode. The two prerequisites for rapid nematode breeding are high temperature and high humidity. If you artificially limit one of the conditions, the nematode is difficult to breed. The most suitable soil temperature for nematode growth is 15-25 ℃, while the cyclamen should reach 8-15 ℃ during the growth period. The most suitable temperature for growth is 15-20 ℃, and both grow at almost the same temperature. Therefore, Use control
