摘要: 为减轻葡萄越冬掩埋的劳动强度,2013/2014 年冬季,在新疆吐鲁番进行双层覆膜、再生棉被和土埋下温度的逐日观测。结果表明,双膜覆盖比再生棉被和土埋的热性能好。双膜最低温度高于-18℃冻害临界值,有较高的最高温度和平均温度的补偿温度,可以缓解最低温度时的冷冻。双膜覆盖“春提早”的作用明显,增加了生长期,使得果穗大而重。双膜还比再生棉被和土埋廉价,容易起步,还可利用温室淘汰旧膜使成本更为低廉。

Abstract: To reduce the labor intensity of burying grapevine for overwintering in Turpan, Xinjiang, China, the values of daily soil temperature under bilayer mulching plastic film and recycle-cotton quilt as well as in burying soil in 2013/2014 winter were measured. The results revealed that the heat-insulating property of bilayer mulching plastic film was higher than that of recycle-cotton quilt and burying soil. The minimum temperature under the bilayer mulching plastic film was higher than the critical temperature of freeze injury (- 18℃), and there was a high compensation temperature of maximum temperature and average temperature. The grapevine germination under the bilayer mulching plastic film was obviously earlier than that under the recycle-cotton quilt and in burying soil, thus the growing period of grapevine was prolonged, and the grape yield and quality was increased. Moreover, the cost of bilayer mulching plastic film was cheaper than that of recycle-cotton quilt and re ycle-cotton quilt.
