糙花少穗竹笋产量与林分状况关系初探

Preliminarily Approaching the Relationship between the Bamboo Shoot Yield and Stand Status of Oligostachyum scabriflorum

糙花少穗竹是一种生长快、用途广的优质笋竹两用小径竹种,通过固定标准地调查法进行影响糙花少穗竹竹笋产量形成因素研究,结果表明:糙花少穗竹的产量主要受立竹株数、每株母竹发笋数和平均单棵笋重等3个因子影响。当糙花少穗竹立竹株数保持在13500～21000株·hm-2,每株母竹发笋数在2 06～2 89个,单棵笋重在249 8～435 2g,糙花少穗竹产量可达到13500kg·hm-2以上。

The results show that Oligostachyum scabriflorum bamboo shoot yield is mainly influenced by 3 factors of living bamboo tree number,shooting number of every maternal bamboo tree and average bamboo weight of single tree.When the living bamboo tree number of O.scabriflorum keeps between 13500 and 21000 trees per hm2,the shooting number of every maternal bamboo tree is 206～289 ,and the single bamboo shoot weight is 2498～4352 g,O.scabriflorum yield may reach over 13500 kg per hm2.
