Ficus disease control psyllids Yung Yung psyllid life history occurred last year in Ficus 4 generations, overwintering psyllids in early April last year 1O spawning, hatching occurs in late 1O months, coming in April In early May began adults, adults emerge in early May peak; s l in early May on behalf of the psyllid eggs, green seedlings, hatching occurs in early June, early July is the peak of the adult; the second generation of fleas in early July spawning, hatching occurs early August, late August peak of adult emergence; 3rd generation fleas lay eggs in late August, 1O adults emerge in early May peak, 4 ~ 1O months came on behalf of the overlap the phenomenon is obvious. Coleus seedlings of full illumination spray softwood cutting techniques of technical management of the entire light spraying softwood cutting techniques, that is, under conditions of full sun, nursery stock prices, the use of semi-woody cuttings shoots good ventilation and drainage seater, seedlings network, adopt automatic intermittent spray 'modern technology, high-efficiency large-scale cutting seedling. Compared with the traditional hardwood cuttings, root cuttings have easy, seedling rate Gao, breeding cycle is short, cutting more than a year can be approved, a rich source of cuttings and scale advantages; the application has easy to learn, easy to operate, invest less benefit Gao and other characteristics. Softwood full illumination spray to defend the plug nursery equipment present, automatic spray device widely used in our country, there are three types, including electronic foliar spray equipment, double long boom spray devices and micro jet piping systems, Beibei seedlings are constructed in common by the automatic controller and mechanical spray of two parts. Electronic foliar spray equipment such devices on the foliage management is more reasonable, it leaves to water cuttings on demand and automatic control of intermittent spray, which is very beneficial rooting. As shown in Figure 10. Double long boom spray device symmetrical pairs of long cantilever self-pressure water spray scanning device having easy to install, durable, uniform spray, etc., because it uses a new and useful way rotary scanning and low refractive spray nozzle, so the normal spray It does not require high pressure. As shown in Figure 11. Beibei seedlings, seedling bases Hua Hin, seedling bases provided by the Chongqing Hua Hin green seedlings base. Beibei seedlings, seedling bases Hua Hin, Hua Hin seedling bases in Chongqing green seedlings base (www.cqxhlh.com) this year introduced a new upgrade, the above picture is for reference only, please call the telephone or pictures on this page, for the latest Information, Contact: Su Bo.
