Abstract: Since May 1998, we had made the assorted technique studies on raising the effect of Casuarina equisetifolia afforestation on the frontal dry sandy land in the draught of C.equistifolia backbone forest strips on Chihu Forest Farm, Hui\'an County and Chishan Forest Farm, Dongshan County both in Fujian Province. Through the experimental studies for about two years, on the basis of analysing the main reasons for the afforestation failure on difficult sites in the draught, the preserving rate of C.equisetifolia afforestation on the sandy land in the draught was raised to 80%～90% by means of selecting the resistant C.equisetifolia strains for application, determining the afforestation models in line with local conditions and adopting the drought-resistant afforestation assorted techniques, including digging deeply for site preparation, putting into the earth removed from other places, mixing mud, making the afforestation season earlier, selecting largely rainy days for afforestation, planting deeply with big seedlings, etc., as well as adopting the combinative afforestation methods of ridging tending for preserving the soil moisture and watering for keeping seedlings in the drought season with the dampproof and windproof engineering measures of building sandy dikes and setting up windbreaks. The important breakthrough has been obtained in the respect of afforestation techniques, which provides the useful experience for the national special protective forest strip engineering construction on difficult sites in the draught in coastal zones.
