The invention relates to a use technology for preventing
empoasca vitis nymphs in an organic ecological
tea garden by using a
spray irrigation method and particularly relates to a method for preventing
empoasca vitis nymphs in an organic ecological
tea garden. The method includes installation of a
spray irrigation device, determination of peak seasons when
empoasca vitis nymphs appear by means of a pot patting method and a tip examining method, and
spray irrigation for
insect prevention. According to the method for preventing empoasca vitis nymphs in the organic ecological
tea garden, spray
irrigation of
fresh water is firstly used in domestic for preventing empoasca vitis nymphs in the organic ecological tea garden, any chemical
pesticide is not added, and the method is suitable for being applied to the organic ecological tea garden; in late spring and early summer of each year when empoasca vitis nymphs are prone to break out and
natural enemies are few, peak seasons when empoasca vitis nymphs appear are determined by means of the pot patting method and the tip examining method, and empoasca vitis nymphs are timely prevented by using the spray
irrigation method, so that development of pest
population can be effectively controlled, loss of tea production due to
outbreak of imagoes is reduced, and the method has an important significance on aspects of reduction of
pesticide residue in tea, improvement of
quality safety of tea, and the like; meanwhile, a spray
irrigation system can be further used to replenish water and apply
fertilizer to tea trees, and the method is an important measurement for general management of the organic ecological tea garden.
