本项试验研究了毛竹笋用林综合技术措施,施氮肥、松土和合理留养的增益。1.综合技术措施增益显著,比对照增产竹笋185.04公斤/亩·度;增产竹材369.39公斤/亩·度;增值171.85元/亩·度。2.施用氮肥增益,尿素施用量(W)与收支比值(In)的关系式为:In=2.1700—0.0151W。每亩施尿素77.5公斤以下具正效益,反之具负效益。3.合理留养母竹可显著提高竹笋产量。4.松土能显著地增产竹笋和竹材,增长数分别为1.8倍和0.40倍。
This experiment studied the bamboo forest bamboo forest comprehensive technical measures, nitrogen fertilizer, loose soil and reasonable maintenance gain. 1. Comprehensive technical measures gain significantly, than the control yield 185.04 kg / acre degree of bamboo; bamboo yield 369.39 kg / acre degree; added value 171.85 yuan / acre degree. The relationship between the gain of nitrogen fertilizer, the urea application (W) and the income-expense ratio (In) was: In = 2.1700-0.0151W. 77.5 kg urea per acre with positive benefits, on the contrary with negative benefits. Reasonable maintenance of mother bamboo can significantly increase the yield of bamboo shoots. 4. Loosening can significantly increase bamboo shoots and bamboo, the growth of 1.8 times and 0.40 times respectively.
