研究了大棚和大棚加地膜覆盖对生姜生长和产量的影响。结果表明 ,大棚内地膜覆盖和大棚栽培生姜可提早播种和延后收获 ,具有早出苗 ,生长量大 ,叶面积扩展快 ,增加株高、茎粗和分枝数以及促进养分充分运输到根茎中的作用 ,产量大幅度提高 ,大棚内地膜覆盖栽培的增产效果尤为突出 The effects of plastic film mulch and greenhouse on the growth and yield of ginger were studied. The results showed that the plastic film mulching in greenhouse and ginger growing in greenhouses could be sown early and late after harvest, with early emergence, large growth, rapid expansion of leaf area, increased plant height, stem diameter and branch number, and full transport of nutrients to roots The role of production, a substantial increase in greenhouse plastic film mulching cultivation yield is particularly prominent
