ẢNH HƯỞNG CỦA NGỪNG TƯỚI NƯỚC ĐẾN RA HOA ĐỒNG LOẠT CỦA GIỐNG LAN HOÀNG THẢO TRẮNG TÍM (Dendrobium sonia 18)

The flowering of orchids in general and in particular the Hoang Thao orchids (Dendronbium) depends on many different factors, including the treatments of irrigation. The irrigation experiment was conducted with four treatments: watering two times per day; stop watering three days; stop watering five days and stop watering seven days (stop watering when stem and leaves of the plants stop growing). Research results have shown that the best treatment for the simultaneous blooming of Hoang Thao variety (Dendrobium sonia #18) was stop watering three or five day, after that watering two times per day.
