摘要
为了探索在不同透光和透气条件下,毛竹竹笋在模具内的生长规律,以0.12 cm、0.15 cm、0.18 cm厚度,200 cm高的不锈钢方形模具为试材,通过四周洞孔大小不同的模具套住竹笋,对毛竹幼竹成竹过程中主秆形状和竹节生长及胸径变化等指标进行分析对比,结果表明:钢板厚度在0.12 cm时,两块模具连接镙栓固定处略微突出;节间长度,直径1.5 cm孔的平均节间长为11.76 cm,直径3.0 cm孔的平均节间长为13.33 cm,分别比对照16.67 cm减少了29.45%和20.04%,处理间达到极显著水平(P<0.01);竹节个数,直径1.5 cm孔的17个,直径3.0 cm孔的15个,对照的12个,比对照增加了41.67%、25.00%,处理间达到显著差异(P<0.05);竹秆高度,直径1.5 cm孔的110.53 cm,直径3.0 cm孔的152.57 cm,分别比对照207.10 cm减少了46.63%和26.33%,处理间达到极显著水平(P<0.001);胸径,各处理之间差异不显著。为此,在方形毛竹材培育生产中应使用>0.12 cm厚度的钢板制作模具,再根据需要,通过模具孔隙的调整,竹笋粗度和模具的大小、长度选择,培育出规格不同的竹材工艺品。
In order to study the growth of Moso bamboo(Phyllostachys edulis) shoots in the molds with different light and air permeabilities,stainless steel square-shaped sleeve molds with thicknesses of 0.12 cm,0.15 cm and 0.18 cm and height of 200 cm were used as confinement for bamboo shoots and pores of various sizes were spotted on the walls of molds.The culm morphology,internode growth and DBH changes of young bamboo plants were analyzed and compared.The results showed that when the thickness of the steel plate was 0.12 cm,the junction of the two mold pieces fixed by screws was slightly protruded.The average internode length was 11.76 cm with mold pores of 1.5 cm in diameter,and 13.33 cm with pores of 3.0 cm in diameter,a decrease of 29.45% and 20.04% compared to the control of 16.67 cm,respectively.There was significant difference between treatments(P<0.01).The average number of culm nodes was 17 with mold pores of 1.5 cm in diameter,and 15 with pores of 3.0 cm in diameter,an increase of 41.67% and 25.00% compared to the control of 12,respectively.There was significant difference between treatments(P<0.05).The average height of bamboo culms was 110.53 cm with mold pores of 1.5 cm in diameter and 152.57 cm with pores of 3.0 cm in diameter,a decrease of 46.63% and 26.33% compared to the control of 207.10 cm,respectively.There was significant difference between treatments(P<0.01).There was no significant difference in DBH between treatments.Therefore,steel plates with a thickness larger than 0.12 cm should be used to make molds for the cultivation of square-shaped Moso bamboo.Then,according to the needs,crafted bamboo culms of various specifications can be cultivated by adjusting the size of the mold pores,selecting the thickness of bamboo shoots and choosing the proper dimension of the molds.
