低产苦竹林复壮技术试验初报

对低产苦竹林采取覆盖、深翻、施肥等措施进行复壮试验,结果表明:覆盖对提早出笋、苦竹笋产量增加、产值增长有显著作用。其中以稻草80%+砻糠20%组合最佳,可以提前苦竹笋上市期41 d,其早期笋产量占总产量39.8%、产值占总产值68.1%;总产值比对照增加123%,早期笋增值额是对照的13.6倍;利润比对照增加253%。竹林复壮培育的林地抚育管理措施以深翻、深层(或全层)施肥效果好,其中深层施肥效果最好。

Experimental Preliminary Report of Rejuvenation Techniques of Low-Yielding Pleioblastus amarus Kene

The low-yielding Pleioblastus amarus Kene bamboo forest was taken covering,deep plowing,fertilizing and other measures for rejuvenation experiment,the results showed that:the covering of the early shoots,bitter bamboo shoots production increases,output growth had a distinct role.Among them,best combination 80% of straw +20% of rice chaff could let the bitter bamboo shoots come into the market 41d ahead,the early-staged shoots yield accounted for 39.8% of total output,the output value accounted for 68.1% of the total output value;total output value increased by 123% as compared with the control,early-staged shoots increment value was 13.6 times of the control;the profit increased by 253% as compared with the control.The deep tillage and deep fertilization had the best fertilization effects of the forest land tending management measures for rejuvenation culture.
