锥栗栽培密度试验及其主要栽培技术

Trial on suitable planting density and cultivation techniques for Castanea henryi

于2004～2010年连续7年进行锥栗不同造林密度的试验,结果表明:稀植有利于提高单株产量,适当密植有利于提高单位面积产量。生产上一般造林密度为每667 m2种40～55株,矮化栽培的在种植10～15年后进行间伐,使造林密度为每667 m2种33株。并简要总结锥栗的高产栽培技术。

Effects of different planting densities on the growth of Castanea henryi were studied for continuous 7 years in 2004-2011. The results showed that low planting densities facilitated the yield of single plant, and reasonable planting density facilitated the yield of unit area. The regularly density for Castanea henryi was 40 - 55 individuals per 667 m2 in pro- ductive practice, and thinning practice for the dwarfing culture should be done after seedling growth for 10 - 15 years, and maintain the density of 33 individuals per 667 m2. Finally, the high-yield cultivating techniques for Castanea henryi were briefly summarized in this paper.
