摘要: 白哺鸡笋用竹林覆盖前用水浇透, 用稻草覆盖。覆盖物下层为发热层, 厚度25 ~ 30 cm , 用水浇透;上层为保温层, 20 ~ 25 cm , 不浇水, 覆盖总厚度50 cm左右。保温层上再覆一层薄膜。结果表明, 覆盖处理的白哺鸡竹林比对照提早74 d出笋, 产量增长29.6 %, 纯收入增长率为2 347.9 %, 投入产出为1∶10.95 。Abstract: Before mulching with rice straw , bamboo shoots forest of Phyllostachys dulcis has been watered thorough .Mulching material of 50 cm in thickness falls into two layers.Sublayer of 25 ~ 30 cm is watered as heating , and upper layer of 20 ~ 25 cm covering with a plastic film uses as heat preservation .The results show that in all mulching plots , the season of bamboo shooting is moved up 74 d earlier than check .Bamboo shoots output and pure income increase by 29.6 % and 2 347.9 % respectively .Mean ratio of input to output is 1∶10.95 .
