Insulation grapes cold winter effect

摘要

【Purposes】 The study of several insulation in cold conditions in Xinjiang Gobi Grape safe winter effect.【Procedures & Methods】 The use of real-time U-plate thermometer to measure temperature changes recorded instrument to study the severe winter conditions, several insulation insulation effect at different depths of grape root, and the cold resistance of winter grape roots at different depths variation; research in the coming year the spring and summerseasons, blooming the results of several insulation grape growth and development. 【Results 】 Several insulation Gobi Grape security winter better, surface temperature is largely improved compared with the control. The D900 collodions + enhanced membrane to improve the 11.69 ℃, non-woven + buried improve the 10.09 ℃. D900 no glue cotton + enhanced membrane covering the grape surface ≦ -5 ℃ continuous days of relatively non-woven + buried reduce eight days underground 30cm, a decrease of 5 days. D900 no glue cotton + Enhanced membrane covering the minimum grape underground temperature than the non-woven + buried there is a significant improvement of the surface temperature has increased 1.57℃, the underground at 30 cm temperature has increased 1.08 ℃, 60cm, underground buried than the processing temperature has increased 1.54℃, the insulation effect. 【Conclusions】 Xinjiang cold conditions, the D900 without glue cotton + film way cover the grapes can live through the winter, is to protect the winter safety of the grapes and grape production.
