毛竹春笋冬出试验

摘要

Experiments were conducted on earlier shooting by mulching with different thickness and different materials at Phyllostachys heterocycla cv.pubescens stands in Huzhou,Zhejiang province.The result resulted that different treatment of mulching had different effect of raising soil temperature,earlier shooting,more days for shoot supply and economic benefits.The experiment indicated that compared with the control,mulching with 10cm of straw,covered with 10cm of bamboo leaves,and covered with 20 cm of rice chaff had the best effect of raising 10℃ soil temperature(20 cm soil depth),of 57days earlier of shooting,of 31 days more of shoot supply,of yield increasing by 240.27％,of output value increasing by 1445.83％,of input-output ratio of 1:3.82.%为使毛竹春笋期提前至春节前后,对试验林地分别用稻草、竹叶、砻糠、杂草等材料进行不同的覆盖处理.结果表明,不同的覆盖处理对毛竹林提高土壤温度、提早出笋时间、延长笋期和经济效益均有明显效果,其中以“稻草10cm+竹叶10cm+砻糠20 cm”覆盖模式效果最佳,平均提高土壤温度(20cm土深)10℃,始笋期提早57d,笋期延长31d,竹笋产量增长率为240.27％,产值增加1445.83％,投入产出比可达1:3.82.
