章節(jié)摘錄

　　Casuarina is raised in high density plantations （ about 10， 000 stems ha） and it responds well for irrigation and nutrient application. The commonly followed rotation period is 4 years with irrigation and 6 years under rainfed conditions. But the duration varies greatly in different areas and between farmers.ln a few places of coastal Tamil Nadu irrigated Casuarina is harvested as early as 2.5 yearsof age whereas Forest Department plantations without irrigation are retained up t0 8 years. Woodproduction varies greatly across location， cultivation techniques adopted and age of the trees.　　Plantations with irrigation and fertilizer application yield 100-150 tonnes ha川of air dried wood （ up to 7 cm dbh）. Under rainfed conditions an average yield of 75-100 tonnes ha， in 6 years dependingupon soil quality and amount of rainfall during the cultivation period. An additional 12-18 tonnes ofmiscellaneous wood is produced per hectare in the form of branches， tops and roots. At the time ofharvest the average height is 12 m and dbh is 8 cm.　　……
