摘要
对雷竹林分进行调整立竹密度与竹龄结构、除草松土、分期施肥、人工灌溉及冬季林地覆盖共５项技术措施，使雷竹笋获得高产、早产和高效益；８种不同覆盖物试验结果表明，比对照均提早始笋期４１ｄ，延长产笋期２４～９７ｄ，增加竹林笋平均产量３３．６ｔ／ｈｍ２，产值３４．２３万元／ｈｍ２；经综合评定，砻糠覆盖为最佳处理，与对照相比，笋产量、笋产值和纯收益分别增长２９．４％、２７０．３％和３１０．２％，投入与产出比为１：８。
techniques like adjustment of density and age structure.Weeding and loosening soil,fertilization by stages.artificial irrigation and coverage in winter could reap high-yield.early shooting and high benefit. Test on 8 coverage material showed that shooting period of the bamboo forest with coverage was 41 days earlier than CK,prolonged 24～97 days of shooting period, increase 33.6 t/hm2 of shoot yield,output value of 340 230000 yuan/hm2.Demprehensive evaluation showed that rice chaff was the best coverage material.Compared with Ck,shoot yield.output value and net revenue of bamboo forest with coverage of rice chaff was respectively increased by 29.4%,270.3% and 310.2%.Input and output ratio reached 1:8.
