| 摘 要： | 1987～2002年,在沿海防护林内层沙滩的退化蕉柑迹地和林中空地中,引种多种优良果树的试验结果表明:(1)首次在这一特殊的立地上成功引种龙眼、荔枝、芒果、余甘子、桃、柿子、番荔枝等优良果树7种,同时,建立了这一立地种植果树特有的栽培技术,提出并验证了确保这一立地种植果树成功的保障技术;(2)种植龙眼和荔枝的经济效益分别是种植湿地松速生丰产林和农作物的12.8倍、7.68倍和9.02倍、5.41倍;(3)在沿海防护林中种植适当比例的果树,不仅不会降低其生态效益,而且还有利于促进沿海防护林体系朝着生态经济复合型的可持续方向发展。

EXPERIMENT AND DEMONSTRATION FOR FRUITS INTRODUCTION ON THE SANDY BEACH INSIDE OF COADT PROTECTION FOREST |
| |
| Abstract: | From 1987 to 2002,some good fruit trees were introduced to degenerate orchard of citrus tree and spare ground in forest on inside sands of coast protection forest.The result indicated:(1)The first success is to introduce 7 species:Euphoria longan,Litchi chinensis, Mangifera indica, Phyllanthus emblica,Prunus persica,Diospyros kaki,Annone squamosa.At the same time,the special cultural techniques are established,and the protection techniques are pointed out and tested to insure success in planting fruit trees.(2)the economic benefit of planting Euphoria longan is 12.8 times,7.68 times more than planting Pinus elliottii and crops, the economic benefit of planting Litchi chinensis is 9.02 times,5.41 times more than planting Pinus elliottii and crops.(3)Planting proper scale fruits in the coast protection forest, not only can't reduce its ecological benefit, but also can promote sustainable development of the coast prtection forest. |
