【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。更多还原

【Abstract】 To reduce the labor intensity of burying grapevine for overwintering in Turpan,Xinjiang,China,thevalues of daily soil temperature under bilayer mulching plastic film and recycle-cotton quilt as well as inburying soil in 2013/2014 winter were measured.The results revealed that the heat-insulating property ofbilayer mulching plastic film was higher than that of recycle-cotton quilt and burying soil.The minimumtemperature 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.Thegrapevine germination under the bilayer mulching plastic film was obviously earlier than that under therecycle-cotton quilt and in burying soil,thus the growing period of grapevine was prolonged,and the grapeyield and quality was increased.Moreover,the cost of bilayer mulching plastic film was cheaper than that ofrecycle-cotton quilt and recycle-cotton quilt.更多还原
