摘要：AbstractChina is a big producer of citrus all over the world, and citrus is an important industry of mountainous area in South China. It is main economic source for farmers in citrus main producing areas. 90% citrus is planted on hilly mountain, wherein the site conditions are poor, it is difficult to operate mobile spraying machine in such areas, knapsack sprayer backed by farmers or pesticide spraying vehicle pushed by hands are main modes for spraying operation, and such modes have disadvantages of high labor intensity and low efficiency, thereby affecting timeliness and effectiveness of prevention and control of plant diseases and insect pests in citrus orangeries. Pipeline spraying technique is adopted in a few orange orangeries, there is no scientific calculation and planning design in the establishment of facilities, thereby pipeline spraying technique is lack of systematic design method. Therefore, technical parameters of key equipment and facilities in establishment of mountainous region citrus orangery pipeline constant pressure spraying facilities are studied and calculated on the basis of theoretical calculation and field scientific experiments, thereby providing theoretical and practical guidance for establishing standardized pipeline constant pressure spraying equipment and facilities.
