摘要
对毛竹笋用林不同覆盖模式下春笋和冬笋产量及产值进行了调查分析。结果表明,砻糠+稻草的传统覆盖模式,可显著提高冬笋产量,且连续2次覆盖后,冬笋产量增幅更为明显,全面采挖冬笋会影响春笋产量;地膜+稻草的覆盖模式在产量方面虽然不及传统覆盖模式,但由于地膜成本相对较低,其产出效益反而高于传统模式,也值得推广应用;竹林经济产出既受笋产量的影响,也受覆盖材料及笋市场价格波动的影响。
The yields and outputs of spring and winter shoots in Phyllostachys edulis shoot forest under different types of mulching were studied. The results showed： （1） The yields of winter shoot in Ph. edulis shoot forest covered with rice chaff and straw, which is the traditional mulching technology, were significantly higher, and after 2 consecutive mulching, the yield presented a even more obvious increase, but the large-area extraction of winter shoots would affect the yields of spring shoots; （2） Ground-film ＋ straw mulching is a type of mulching yielding less shoots than rice chaff ＋ straw mulching, but as ground films has relatively low costs, its outputs are even higher than the traditional mulching, so it is worthwhile promoting and applying. The economic outputs ofPh. edulis shoot forest are influenced by shoot yields and mulching materials and bamboo market price as well.
