【摘要】 慈竹是成都地区及川西平原的主要乡土竹种,也是四川竹林资源规模最大的竹种,竹林的退化是目前林农面临的一个现实问题。为进一步提高慈竹林地生产力,促进产业发展,成都市园林科研所首次从江西引进竹腔施肥丰产技术,将BNP毛竹增产剂应用于慈竹株丛,作了BNP毛竹增产剂同一浓度药剂的重复对比试验。试验结果表明,BNP毛竹增产剂在一定程度上可以增加慈竹株丛的出笋量、出笋率、成竿量、成竿率以及成竿粗度。其中,慈竹出笋量、出笋率的增加效果比成竿量、成竿率以及成竿粗度的增加效果显著。更多还原

【Abstract】 Neosinocalamus affinis is the main native bamboo species in Chengdu area and the plain of western Sichuan,and also is the largest species of bamboo resources in Sichuan province.At present the degradation of bamboo forests is a realistic problem to agroforestry.In order to increase the productivity of the bamboo forests and promote the industrial development,Chengdu Institute of Landscape Science has firstly imported the high-yield technique of cavity-injecting fertilization from Jiangxi province and applyied BNP to N.affinis strain plexus.The comparative experiment of the same concentration of BNP on N.affinis indicated that BNP could increase the production and rate of bamboo shoots and the production and rate and diameter of bamboo pole forming,and the effects on the former two were more remarkable than others.更多还原
