Thành lập vườn cây ăn quả là một đầu tư dài hạn và do đó cần quy hoạch hoàn chỉnh. Bất kỳ sai lầm đã cam kết trong quá trình lựa chọn của trang web, mật độ trồng, lựa chọn giống, chất lượng cây giống . phản ánh rất nhiều hiệu suất vườn cây ăn quả. Đối với quản lý có năng suất bền vững, nó là rất quan trọng chọn một trang web tốt cho vườn cây ăn quả. | Ministry of Agriculture and Rural development THE SOUTHERN FRUIT RESEARCH INSTITUTE THE TECHNICAL PROCEDURES FOR GROWING AND CARING OF CITRUS IN VIETNAM VO HUU THOAI I. SITE SELECTION Establishment of an orchard is a long term investment and hence needs the complete planning. Any mistake committed during selection of site plant density choice of varieties quality of seedling. reflects greatly on the orchard performance. For got management and sustained yields it is very important to select a good site for orchard. Climate Temperature It should be remembered that the optimum temperature range for tropical trees is between 23-30oC if temperature is low at 10oC can damage tropical trees. Rainfall In general a climate with low rainfall and plenty sunshine in good for tropical trees. High rainfall areas are less suitable for fruit trees because of pressures of pests and diseases lower yield and poor fruit quality. Soil Fruit trees can grow and produce well in a wide variety of soil types except very light sandy soils and heavy clay soils. In general most fruit trees prefer the soil pH between 5.5 and 6.5. The water table should be no higher than one meter below the soil surface. Other important factors Day length the amount of sunshine the level of relative humidity latitude altitude and slope of land may all affect fruit tree growth fruit yield and .
