摘　　要：通过比较9种不同覆盖处理对雷竹保护地栽培园的始笋时间、笋期长短、笋期延长时间、早期笋产量和早期笋产值等的影响,分析了不同覆盖材料使用后对雷竹园经济效益的提高效果。结果表明,9种不同覆盖材料处理均提早了雷竹始笋时间,延长了笋期,增加了笋产量和产值,其中以谷壳单独覆盖提早出笋的效果最优,提早了笋期55 d,延长了笋期35 d,早期笋产量达到564.8 g/m2,产值为8.47元/m2,总平均产量为903.4 g/m2,总平均产值为9.83元/m2,分别比没有覆盖的雷竹园总平均产量增加了40.1%、总平均产值提高了2.8倍,提高经济效益的效果非常明显。其次是稻草加谷壳的混合覆盖处理效果较好,并随谷壳比例的增加,始笋时间、笋期及其延长时间、早期笋产量和早期笋产值等也都表现不错。单独稻草覆盖处理在一定厚度范围内,随厚度的增加效果也明显。而腐烂玉米秆因含有机物少,不适宜做雷竹保护地栽培覆盖材料。By comparing the effects of 9 different mulching treatments on starting time,duration time and prolonged duration time of bamboo shoots and the yield and production value of early bamboo shoot of protected cultivation of Phyllostachys praecox C.D.Chu et C.S.Chao f.prevernali S.Y.Chen et C.Y.Yao,the promotion effect of different covering materials on economic benefit of P.praecox f.prevernalis forest were analyzed.Results showed all the 9 covering materials advanced the starting time of bamboo shooting,prolonged the shooting duration time,and increased bamboo shoot yield and production value.Covering with rice husk had the best promotion effect as the shooting starting time was advanced by 55 d;shooting duration time was prolonged by 35 d;yield of early bamboo shoot was 564.8 g / m2;the output value was 8.47 Yuan(RMB) / m2.The total average yield was 903.4 g / m2;and total average production value was 9.83 Yuan(RMB) / m2,which was 40.1% and 2.8 times higher than the control without any covering,respectively;the economic benefits improving efficiency was obvious.The straw and husk mixed coverage had the second efficiency;and the promotion effect increased with the increase of husk ratio.The promotion effect of straw mulching treatment alone increased with the increasing of mulching thickness in a certain range.Rotten corn stalk contained little organic compounds thus was not suitable for being used as covering material.
