摘要
为探索毛竹笋材两用林平衡施肥技术,在三明市三元区中村对毛竹笋材林设立固定样地,开展平衡施肥对竹林生长状况的影响研究。结果表明:在N、P、K配比为1∶0∶39∶0.33时,笋材两用竹林的新竹平均胸径最大,新竹株数也在较高水平,配合施用少量的有机肥(有机含量≥50%,N、P、K按干计为6%)和炭质肥(竹炭15%+竹醋液5%+动物粪便72%+废菌棒8%)能有效地提高新竹数,降低退笋率。
The permanent sample plot was established in the moso bamboo forests with dual - purpose of shoots and timber at the Zhongcun Township, Sanyuan District of Sanming Municipality to conduct the research on the effects of balanced fertilization on bamboo forests growth so as to explore the techniques of balanced fertilization suitable for moso bamboo forests with dual - purpose of shoots and timber. The results showed that when the NPK proportion was 1：0. 39：0.33, the average diameter at breast height （DBH） of the new bamboos in the moso bamboo forests with the dual - purpose of shoots and timbers was the largest, and the number of the new bamboos was at a high level. Application of a little amount of organic fertilizer （organic content ≥50%, N,P,K was 6% calculated as dry weight） and carbona- ceous fertilizer （bamboo charcoal 15% ＋ bamboo vinegar 5% ＋ animal waste 72% ＋ waste biomass log 8% ） may effectively improve the number of new bamboos and reduce the degraded shooting percentage. In addition, the applica- tion of carbonaceous fertilizer could increase the soil permeability, water holding capacity and fertilizer retention capac- ity that can not only save the labor inputs but also reduce the production cost.
