新疆天山北坡阜康和南麓吐鲁番葡萄双层覆膜越冬试验结果表明,采用双层覆膜的葡萄,单株产量提高5.2-13.0kg;果穗增大3.7-7.8cm,增重114.9-293.9g;果粒增重0.1-0.6g;新枝生长量增长47.3-89.3cm,一级品率提高20%。经分析,主要是膜下最低温度高于临界值上限-16℃不会受冻,在最低气温日都有高于土埋50-90℃·30m的补偿温度和6-9h的补偿时间,整个冬季的补偿温度是840.5-1435.9℃·d。寒冷期后平均温度越来越高于土埋,10℃萌发的日期提前了10-20d。高温环境和长生长期是增产的主要原因。土埋越冬有长期低温的危害。
The results of overwintering experiments on double-layer mulching of Tu-Fu grape in Fukang and the southern foot of Tianshan Mountain in Xinjiang showed that the yield per plant increased by 5.2-13.0 kg with double-layer grapes; the ear increased by 3.7-7.8 cm and the weight gain was 114.9-293.9 g; fruit weight gain 0.1-0.6g; growth of new branches increased 47.3-89.3cm, a product rate increased by 20%. After analysis, it is mainly that the minimum temperature below the membrane is higher than the upper limit of the critical value, and the temperature will not be frozen at -16 ° C. At the minimum temperature, the compensation temperature and the compensation time of 50 to 90 ° C and 30 to 30 m are higher than the buried temperature, Winter compensation temperature is 840.5-1435.9 ℃ · d. After the cold period, the average temperature is higher and higher than the soil burial, 10 ℃ germination date ahead of 10-20d. High temperature environment and long-term growth is the main reason for increasing production. Buried winter over the long-term low-temperature damage.
