本文选择同一立地条件、相同品种、同样造林管理的油茶新造林,采用了地膜覆盖、深施基肥和每年冬季追施有机肥等抚育措施,对油茶早实丰产开展研究,对照样地未进行地膜覆盖、施基肥和追施有机肥.结果表明,地膜覆盖对新造林成活率,深施基肥和追施有机肥对油茶新梢N、P、K含量、高径生长、冠幅和鲜果结实量有显著提高.
本文選擇同一立地條件、相同品種、同樣造林管理的油茶新造林,採用瞭地膜覆蓋、深施基肥和每年鼕季追施有機肥等撫育措施,對油茶早實豐產開展研究,對照樣地未進行地膜覆蓋、施基肥和追施有機肥.結果錶明,地膜覆蓋對新造林成活率,深施基肥和追施有機肥對油茶新梢N、P、K含量、高徑生長、冠幅和鮮果結實量有顯著提高.

New plantations of Camellia oleifera with the same site conditions, variety and management were selected as the sample plots to study the cultivation techniques for early-fruiting and high-yield plantations of Camellia oleifera by means of film mulching, deep base fertilization and additional organic fertilization every winter. There were no film mulching, base fertilization or additional organic fertilization in the control plots. The results showed that film mulching could significantly increase the survival rate of the new plantations and deep base fertilization and additional organic fertilization could significantly increase the contents of N, P and K in the new shoots, height and DBH growth, crown breadth and fruit quantities.
