为探究施肥时期对毛竹林出笋成竹及新竹生长的影响,2019-2022 年在福建省永安市进行了不同施肥时期试验,设置 3 种施肥时期处理:5 月份施肥 1 次+挖冬笋前 1 个月施肥 1 次(处理A),5 月份施肥1 次+边挖冬笋边施肥 1 次(处理B),5 月份施肥 1 次+挖冬笋后1 个月施肥1 次(处理C),以不施肥作为对照(CK),分析比较不同施肥时期对毛竹林春笋出笋量、成竹量及新竹生长量的影响.结果表明,以处理B对毛竹林出笋成竹及新竹生长的促进作用最好,平均春笋出笋量达 939 个/hm2,平均成竹量达883 株/hm2,新竹平均胸径达 10.9 cm,平均竹高达 12.3 m,分别较对照提高 28.10%、32.38%、14.74%、14.95%.研究结果可为笋竹两用毛竹林施肥时期选择提供技术参考.
To investigate the effects of fertilization time on the shooting and young bamboo growth in moso bamboo forest,fertilization tests were conducted at different times from 2019 to 2022.Three treatments were set to compare and analyze the effect of the time to fertilize on shooting quantity,quantity of bamboo culms and growth of new bamboo,i.e.,fertilizer application in May and then in the month prior to winter bamboo shoot digging(Treatment A),fertilizer application in May and then when digging winter bamboo shoots(Treatment B),fertilizer application in May and then in the month after the digging of winter bamboo shoots(Treatment C),and no fertilization(CK).The study reveals that Treatment B has the best effect in improving shooting and new bamboo growth in the moso bamboo forest.Under Treatment B,the spring bamboo shoot production,the average quantity of bamboo,and the average diameter at breast height and the average height of new bamboo culms are 939 shoots/ha,883 culms/ha,10.9 cm and 12.3 m,28.10%,32.38%,14.74%and 14.95%higher than the CK,respectively.The research results would provide technical references for the selection of the time to fertilize in shoot-timber producing forest.
