A Report of the Citriculture on the Coastal Sandy, Windy Land

Abstract

The first step in building a citrus orchard on the coastal sandy, windy, arid land is planting effective wind-protecting shelter belts. The belts can reduce the critical wind speed, which forms the sand flow, usually 5-6 meters per second to less than 3 meters per second. It effectively avoids the outflow of sand from the orchard. Secondly, the suggested ideal fluctuating range of ground water level under the sandy soil surface during the rainy season is 30-60 cm. Thirdly, a close water source for irrigation should be available. Fugie,’ 'Ponkan’ and satsuma are the citrus cultivars most suitable for planting on the arid land and having high, stable yields. Simultaneously, it is considered that 6625 arrow-tongue pea, Indian compea, Sun flax, Amorpha, etc., are the green manure crop cultivars which are most suitable for planting on the arid land. They improve productivity and play an important role in soil improvement by increasing the fertility and reducing the soil surface temperature by covering it.
