摘要
采用正交设计的方法、对雷竹笋用林进行田间试验,经过两年的重复试验结果表明:试验地竹笋产量比对照地增加5936.0kg/hm2,平均增长296.91%;纯收入平均比对照地增加7.7432万元/hm2,平均增长399.78%.春笋冬出,平均出笋期比对照提早25天,最早的小区比对照提早55天.早出笋产量最高的占总产量的87.71%.投入产出比最高的达1:12以上.覆盖物种类(A)对产量.产值差异性显著;覆盖厚度(C)对产值差异性显著,对产量差异不显著;覆盖时间和施肥种类(D)对产量、产值差异性均不显著.综合田间试验的产量、产值及经济效益.
Adopting the orthogonal design principle, using variance analysis, this paper researched into the effects of different coverings, different covering times, different covering thicknesses and different fertilizers applied before covering on shooting times, yields and values on Phyllostachys praecox shoot stands, the results supplied alternative bumper-yield treatment for shoot stand management.
