| 通过对极端干旱区葡萄在不同微喷弥雾调控方式（WP1,架上喷水1 h;WP2，架下喷水1 h；WP3，地上喷水1 h）下微气候因子与葡萄果实生长形态及糖度的监测，分析葡萄园微气候因子变化规律及其与葡萄果实生长形态和糖度的关系。结果显示：采用微喷弥雾调控可有效降低葡萄园温度和增加湿度，与CK处理（常规滴灌，不喷水）相比，白天平均温度低2.9℃~3.3℃，平均温度低2.5℃~2.9℃，夜晚平均湿度高4.7%~5.5%，同时可促进葡萄果实生长和糖度累积，WP1、WP2和WP3与CK处理相比，果粒纵茎高出2.88、1.76、0.9 mm，果粒横茎高出1.33、1.80、1.76 mm，果粒均重高出0.22、0.26、0.25 g，糖度分别高出7.75%、3.96%和5.53%。在葡萄果实生长发育过程中，白天平均温度和平均温度是影响葡萄纵径和横径的关键微气候因子，晚上平均湿度是影响葡萄果实重量和糖度的关键微气候因子，在白天平均温度为30.4℃~33.8℃、晚上平均湿度为49.5%~50.5%时接近葡萄果实纵径、横径和果粒均重拟合值最大值。根据其相互关系和建立的回归模型，得出可以用白天平均温度、平均温度和晚上平均湿度对该地区葡萄生长和糖度变化进行分析和预测。 |

| By monitoring the microclimate factors and the growth and sugar content of grape fruit in different mist control modes (WP1, spray water on the grape trellis for 1 h; WP2, spray water under the grape trellis for 1 h; WP3, spray water on the ground for 1 h) in the extreme arid area, the change of the microclimate factors in the vineyard and the relationship between the microclimate factors and the growth and sugar content of grape fruit were analyzed. The results showed that the temperature and humidity of vineyard were effectively managed by mist regulation. Compared with CK treatment, the average daytime temperature was 2.9℃~3.3℃ lower and the average temperature was 2.5℃~2.9℃ lower (conventional drip irrigation, does not spray water). The average night humidity was 4.7%~5.5%. Meanwhile, it promoted the growth and sugar accumulation of grape fruit. Compared with CK treatment, WP1, WP2, and WP3 increased the vertical berry size by 2.88, 1.76 mm, and 0.9 mm, the horizontal berry size by 1.33, 1.80 mm, and 1.76 mm, average weight of the berry by 0.22, 0.26 g, and 0.25 g, and the sugar content by 7.75%, 3.96%, and 5.53%, respectively. During the growth and development of grape berry, the average temperature and the average daytime temperature were the key microclimate factors that affected the vertical and horizontal dimensions of berry, and the average night humidity was the key microclimate factor affecting the grape weight and sugar content. The average daytime temperature was 30.4℃~33.8℃, and the average night humidity was 49.5%~50.5%. It was close to the maximum values of the modeled values of the vertical diameter, the horizontal diameter, and the average weight of the fruit. According to the relationship and regression model, it can be used to analyze and predict the growth and sugar content of grape in this area. |
